Prof6 P. H. Rolfe,
Vigosa, Minas Geraes,
Brazil, SOUTH ARNICA.

Dear Professor Rolfe:

I thank you for yourrecent letter in regard to the scab of Lima

beans caused by Elsinoe. So far as I have been able to ascertain this

disease has not been found in South America.

Recently I have been studying Citrus scab from South America.

Professor Swingle suggested that I write to you for specimens of this

disease. I would be very glad to have specimens of scab ol Satsuma-fruits,

on sour orange leaves, and on sweet orange including Navel orange, if and when such material is available. Where specimens of fruit are sent if the rind could be peeled off and pressed it should arrive in satisfactory condition. Leaf material if pressed dry should also be satisfactory for study

when received.

Thanking you in advance for the favor I am asking, I am Very sincerely yours,



Anna E. Jenkins
Associate Pathologist

Dear Dr. Rolfst

Your letter of March 19th has been received. I am
glad to see that you approve of our mycological
explorations of Colombia, as a basis for future work
in plant pathology. it would be nice and handy to start
something of this kind in Minas Geraes.

I am starting on a three Months' vacation, for
Venesuela and probably Colombia, the first week of June.
I am planning to collect fungi and advise the Venezuelan
government on certain proposed agricultural activities.
If I can be of any service or if you have any suggestion
I shall be glad to be at your service.

Yours very truly,

Dr. P.H. Rolfs

Dear Dr. Rolfs
I write to thank you for your very kind remarks as to my article published in the Revista
da Agricultura. It was extremely gratifying to me to receive such a letter from you.
I also wish to thank you for the two leaflets which I received. I was much interested by that
dealing with the culture of the "Sapucainha." I had already obtained some seeds of this plant, which I understand is fairly common in this neighbourhood and will be much aided by your work in the plantation I hope to set
out in this Experiment.Station.
It is possible that my article, with some alterations, will now be published by the Repartigo de Publicidade of the Secretaria, as the new Secretary of Agriculture is Dr. Theodureto de Camargo, who I know. If so, it will of course be easy to obtain copies and, if any Minas student should desire it, I could
have them forwarded.
I was given ten separate copies of the
article, as I asked for them before the Jan. number was published. The majority pf these I have already distributed. In any case, however, I will probably arrange to
have more copies, even if it is not published by the S.Paulo Secretaria as I understand that the Sociedade
Rural desire to publish it in their periodical and I
will arrange for them to print some separates.
My kind regards to Misa Rolfs,
Yours very sincerely
















Dear Miss C.Rolfs


-any thanlfs for the four publications you so kindly

sent me and whose contents T appreciate much.I know the work and troub~ le these prints need but a success,and this is one,values all spent efforts.You are living in a country which has a sure future and I w wish you all success in your enterprise.Brazil also feels the crisis of the world market;but as she disposes on a greater diversity of crops than Egypt she will be better on;Egypt disposes only on cotton and onions for exportation.

Very obliged for your kindneses,I remain

Yours very truly

Em'experiwentacao de campo, a heterogeneidade do solo e, sem duvida, o factor mais importante.Q aan
do se passa em revista os trabaUnios dos *ul imos vin.-te annos, realizados em di,rerocs Laize-. ve-se que nao tem sido pequena a preoccupaqao de estabelecer
methods pelos quaes se'possa fazer uma estimative dos erros expex imentaes, ao mesmo tempo que se Prom
rava standardisar esses 'me-thodos

My dear Doctor Rolfs:

Dr. 0. E. White has suggested that I write to you concerning the possibility of
securing seed of any types of peanut (wild or cultivated) which show unusual characteristics such as odd seed coat color, flower color etc.
I am anxious also to obtain viable seed of all the
species of the genus Arachis which are found in
South America so as to broaden a cytological study
that is now limited tothe chromosome structure and meiotic processes of our common peanut A. hypogaea.

I hope you may be able to aid me either directly or by referring me to a capable person
whom you think could help me to secure odd types of
A. hypogaea and seed of other Arachis species,
Thanking you, I remainVery truly yours


Ladley Rusted.

BRAZIL.

Dear Mr. Rolf

It is rather difficult to obtain definite information from South America and consequently
I am taking the liberty of writing to a one-time colleague,
although I expect you will be very fully occupied without
the added load of outside requests.

I am concerned with the disease of tobacco know here as "blue mould" and ascribed to
Peronospora hyoscyami DeBy. although it is closely related to, if not the same as, P. nicotianiae Speg. described in 1891 from Argentina. I understand that Brazil produced
some 61 million pounds weight of tobacco in 1931-32, mainly
in the Bahia area, and as South America is the home of
tobacco and probably of P. nicotianiae I find it hard to
believe that no downy mildew occurs with you.

I shall be deeply indebted to you if you can find time to ascertain whether a downy mildew does
occur and, if so, what it is. Specimens would also be
extremely valuable. We have found that the downy mildew ("blue mould") attacks every species of Nicotiana we have
inoculated under glasshouse conditions.

I shall be glad to send you in a week or two a bulletin on the disease as it occurs in Australia.

You are probably aware that it is occurring again in North Carolina this year.
Kindest personal regards,

Yours sincerely,


(B. T. Dickson)
Director, Australian Tobacco Investigation, and Chief of the Division of Plant Industry, Council for Scientific and Industrial Research.

Dear Mir. Dickson:

Your letter of Apr. 27th reached us a few days ago.

Since coming to Brasil I have given almost no time at all to the study of plant pathology. My time is extremely loaded with matters of a general nature.

Prof. A.S.Muller, a uornell graduate, has been in charge of the Department of Plant -rathology for nearly three years. I know that in a general way he has made studies of the tobacco diseases in Minas and possible in other Otates.

313 W. 6th Ave., Denver, Colo.
March 5, 1932


Dlaldo P. Johnson, Atty.,
Gloyd Bld0.
Kansas City, Mo.

Oear Sir: Your attitude to-7ards Mr. Hillrman's conditional $400.00 settlement looks like double barreled rapacity.

I threw $1800.00 into a well, due toadmitted forgery and manipulation of my Acct., also $700.00 in stock profits.

Christophers tried to bribe me into getting more money, promising to keep the grain Acct. open to trading after the $4000.00 liability had been discovered. "Don't do it"' Said Tom Coghlin. Stanley Christopher was hoodwinked by employees that it was merely an oversight, Tom Coghlin tried to shoo me alay; "get -out and stay out", on pretense of protection. I demanded a statement of my Acct. from Tom. A confession of forgery, unauthorized grain trading and house robbery was the result.

After informing S. Christopher, I was accused in my wife's presence, of having prior knowledge and was suspicioned of being 'in' on the game. The bonding Co. was now responsible for the Approx. $7500.00 loss on my Acct.

Later S. Christopher accused my wife of attempted bribery after all information was given. If the case is too much for Mr. Hillman's more money Referee, what will be the additonal cost to get an Insanity Commission? I want to kno1 where I'm at, I never realized our Judges were such inferior cheap skates. Is that why my $500.00 equity in the Masonic Temple, Topeka, Kans. is practically worthless?

If chagrin is in the oblivion maybe I can care you-guys. Psychologists fathom reformers like the farmer antd the giraffe.

In spring, 1896, Onaga, Ks. was agog. Two likable boys of 16 htd a horrible fight. One UNANGERED, but forced to protect himself, said, "Turn around here and take your medicine" The other, fell unconscious; marked for life. The doctor had a 6 hour job. R, P. Crum, Stafford, Ks offered his hand, saying, "Geo., I want to be your friend. That's the best thing that evar happened to me"

It was ethical for Dr. W. H. Crisp, Denver, to force an Irishman into court to pay for hastening his sisters death. There is a Dame who would have "called" the Dr, on such Amer. rascality.

Copies will be mailed to Mrs. S. Christopher, S. Christopher, Jr., K.C. Judges,
Better Business Bu., Pres. Amer. and K.C. Bar Assns., K.U, where the Christophers are supposed to be educated, Ed A, Guest, Darrow, The proud Mrs. H. Hoo*er, Gov. Murray, other Christopher Attys. too big to handle this case, Pres. N.Y. Stock Exchange & Chgo. Bd. of Trade.

Geo. Rolfs.





there is no science the study of which is more commendable than the knowledge of the true interest in one's country; and perhaps there is no kind of learning more abstruse and none more generally neglected, Hence it is that we every day find men in conversation contending warmly on some point in politics, which, although it may nearly concern them both, neither of them understands any more than they do each other.
--Benjamin Franklin.

A legal pharmacist pulled off stunts that made a booze-selling druggist look like an angel; but things went wrong. A prescription was received ordering Lloyd's aconitia in teaspoonful doses. "W1hy, wait a minute; why echinacea is what I want," said the doctor. A mother was worse after childbirth. Two roads are before you. Deliver the rectified prescription and trust to the Lord, or "squeal" and stick up a "For Sale" sign. Blood poisoning was averted; also suit for "professional services rendered."

"Bartenders who are going into essential industries may hear some intelligent
conversation. It will be a welcome change from 'One more and then we'll all go home,' and 'Now, man to man, am I right or am I wrong?,"--Kansas City Star

"I have been pretty fair; maybe I should be good," thought a booze-selling druggist; "I'll see if I can pick up an idea worth while."

"Mr. Gunsaulus, you said that to do good in the world, merely for the good that is done; and to be honest, simply because honesty is the best policy, IS OF LITTLE CONSEQUENCE OR VALUE, unless the one who does these things professes Christianity and believes in a Supreme Being. You also said that SINNING is MISSING THE MARK. I want to 'call' you on that."

"Who are you?" He asked. "An ex-druggist," was the reply. "I have no time for a matter of conjecture," said he, and hung up. it was not long till F. W. Gunsaulus, Chicago, turned his philosophy upside down.

Coolidge says conditions are bad. "Begin at home." His pastor deplores that agnostics, not Christians, uphold evolution. And we need more "living apostles of Christ,' like Calvin. A religious microscopic view shows Jesus less tolerant. "Blood-thirsty Christians."--Darrow. Rev. Hargett asked forgiveness for Darrow's using his church. "Has Every Man His Price?" "What a vicious, dirty arrogant septic he is who plucks out faults without consideration for the good," says Hargett. The Kansas City Star printed such with flying colors. Burris Jenkins read it thusly: "It is an easy thing to be a crank, faddist or lunatic on religion". Which is, "Let he who has not under the microscope.

"Jesus is not seeking those who can explain Him, but those who can follow Him. What the world needs is less analyzing, more obedience and less philosophizing." -Dr. D. J. Evans who boasted of having the world's largest bible class in Kansas City.

"In the tenth century an Italian woman of high caste, refused to eat with her fingers, using a crude fork. She disgraced all Italy." Science Service Bureau, :.ashington, D. C.--Were there theo),ogians then?

To praise Lincoln is fine. To practice his philosophy is a crime. An agent unsuccessful in selling him a book, asked for a letter recommending it. "To any one who enjoys reading this book, it is a good book for that one to read." A simple, supple, SELF-RELIANT, honest mind. SERIOUS, BUT NOT TOO SERIOUS. They say he scratched his head; if so, crude, but not rude. Not good, not unfair. Not GREAT, Not SMALL. One who used his brain--that's all.

You are the one that you must fight. You are the one who must choose the right. GOD gives you the equipment, but He, lets you decide what you want to be.--Excerpt., Ed. A. Guest's "EQUIPMENT," a poem inspired by a booze-selling druggist.

Ue pilgrimage to theinembrance of jealousy, hatefulness, seclusion. (Roosevelt ) The long euphonious ear that finds a way in, will find a way out. Not a strain is lost. They back up for more. An antidotal fiend.

Bishop Edwin Holt Hughes, 'hicago, boasted that a college boy returned to his home town and wiped out the saloon. A Kansas town boy quit high school, for fear of becoming an educated fool, wiped out the biggest 'Hell Bent For Heaven' church in Chicago, and was ashamed of the job.

The pastor, in the habit of not using his brain, died a broken-hearted man.

Christianity has never been tried.-- H. W. Beechet.

You reach for high thots; I fail to fight off the low ones.

(Letter of Dr. Webber, sent by Haywoodf
(OrigiAnal returned).

University of Ualifornia
College of Agriculture

Graduate School of Tropical
agriculture
and Citrus Experiment Station
Riverside, California
April 2, 1932.
Mr. Wyndham Haywood,
Box 426,
Winter Park, ilorida.
Dear Sir:

Your communication of April 12 addressed to the itrus Experiment Station has been handed to me for consideration.

The paper on rootstocks which I was preparing and hich I apparently referred to in writing you is primarily on rootstock selection or the improvement of citrus rootstocks by the. selection of good vigorous type seedlings. This. publication has been delayed and I do not know how soon it will be Assued. I supposedly read the final draft of the manuscript about a month ago and it should he out in a month of so. Publication matters, however, are moving very slowly and I do not know how soon this will be issued.
I may say that this publication is not intended to be for
general distbution as it will be a scientific treatment of the subject. I will, however, expect to forward a copy to you as it may give you some information that will be of interest. I shall expect sometime in the fLtUre to issue general bulletins on rootstock trials but Cannot say as wtb when publications will be prepared and it will therefore probably be just as well to answer certain of your questions by letter.
You ask in particular as to whether Cleopatra Mandarin, Rangpur lime and Shaddock are used at all as stocks and with what success.

The Cleopfatra Mandarin, as you doubtless know, has been used rthR. extensively in certain parts of lorida and I believe was first advocated by the Royal Palm Nurseries, through Mr. Reasoner.

I have recentl spent a month in Florida studying the rootstock situation. In mango places 1 found the Cleopatra being used with fair success. From the evidence I was able to obtain, however, it did not seem to me that this stock could be considered as hAving given favorable results except for tangerine or mandarin varieties. It could not be considered in any sense of the word, as a failure for varieties
of the common orange or grapefruit, but does not apparentlS gi'e as satisfactory results as the Rough Lemon stock on the light sandy lands and the soir orange stock on the heavier flatwoods Or hammock lands.




It is probably Ansafe to generalize, but I would be inclined to believe that Rough lemon and sour, Ander& respective soil conditions to which they are suited, will in general give better results, even
with the mandarin types.
I heard some suggestions with reference to the-use of the Rangpur lime but I can see no reason why this variety should be considered as good stock. In the first place, it is a small growhag tree and is very susceptible to frost injury so that apparently it
could not be considered in the same class with other standard stoCks. I have seen no trials of the Rangpur lime and I am this speaking on general principles.

In some cases Shaddock stocks haie been used and grapefruit,
but experience with these stocks usually have been rather disappoigting. Some 35 years ago grapefruit was advocated extensively in Ylori da and also in California for use as a stock but now, after a 30 year period, I find both in California and in Florida about the same attitude. One can find certain good groves on grapefruit, or# sometimes
on types of Shaddock, but the stock is generally consideredLas an erratic one and as a shy bearer requiring extensive fertilization to keep it in production dondition.
I cannot find that it is in general favored any where in either tkifornia or 'lorida. Of course, we must remember that when we speak of the Shaddock or grapefruit stock, or indeed of the stock of any other citrus species we are talking of a conglomerate assembly of individuals, many of which differ from each other. The majority of grapefruit or shaddocks might be worthless as stocks and yet we might find that a certain shaddock or grapefruit would turn out successfully.
ACll of our informatiom heretofore has' been limite& to a dis cussion of species and not to definite varieties and the information that has accumulated is therefore very unsatisfactory. It will he necessary for us in the future when we con& mn grapefruit, sour orange, or sweet orange, or whatever it may he, to condemn a certain type oft these species, or favor a certain type. In other words, we must know the actual variety that is being used and be able to obtain the same thing the second time.
If there are any special questions you have in reference to stock matters I shall be glad to discuss them with you by letter and from time to time i may be in position to send you ppublications outlining the work we are doing.

The publications from the Citrus Experiment Station are
all made through the California agriculturall Experiment Station which has headquarters at Berkeley. I am enclosing here-with a list of bulletins now available from which you could request any that you might desire. I would suggest, however, that you made this request directly to the vxberiment Station headquarters at Berkeley. In the work of our Experiment Station we cover subtropical fruits as well as citrus and vyou will find certain publications issued on the avocado.

With reference to nurseries handling subtropical fruits. I would refer you to armstrong Nurseries, Ontario, and the Coolidge Rare lant Gardens, Pasadena. I should be rather surprised if you will obtain from these nurseries anything that could not be obtained just as well through the Royal Palm Nurseries, at Uneco, -lorida, or probably #ny other good nursery in Florida. The Royal Palm nurseries aaL-.

particularly good and have a wide range of material. You could of course ontain material from them easily while you might have difficulty in obtaining things from California, owing to the quarantine laws.

We do not issue a catalog ~'the graduate school of tropical
agriculture as we give only graduate work to comparatively few students and this is given as a part of the graduate work of the University of California. One would, therefore, find our part of the University of California discussed in the catalog of the Lraduate School

My dear Professor Rolfs,

I have handed over your letter to Mr. F. J. Pound who is
------ engaged on a long term cacao research scheme. I enclose a letter

from Mr. Pound which should give Dr. Novaes the information he wants
in the first place, and open the way for further correspondence,

direct with Mr. Pound if he wishes to correspond.

2, Dr. Novaes should note that when he applies for seed it

will have to be sent out by the Director, Department of Agriculture,

Trinidad.

3. I a glad to hear such a good account of the affairs of

your College and trust the satisfactory conditions may continue.

We are very hard pressed for cash here. Our budget for scientific

work and teaching has been pretty well maintained. Salaries have

been cut. We are, however, coming out all right, I think. We

have no endowment and have to run on annual grants.

4. I remember how pleased you were with the Cassias here

especially C_.javonica. The javonica avenue will be a fine sight P. H. Rolfs, when

Agricultura de Minas-Geraes,

when in bloom. Our Cassias are just beginning to show their flowers for this season.
5. Thanks for your remembrances. -We have been hoping that we might see you passing this way again.
With kindest regards to you both from us both.
Yours sincerely,

THE PHIFER STATE BANK
STATE, COUNTY AND CITY DEPOSITORY


GAINESVILLE, FLA. April 18,1932.

Dr .P.H.Rolfa 3 z,
Vic osa Minas-Gerais,
Brasil.
My Dean Dr.Rolts:I want to thank you for your good letter and the check received some days since. We do appreciate the check for it helped us out quite a little.
The Stewards made a desperate effort to collect the amount in full that was underwritten but did not succeed in getting it all but the larger part of it and the underwriter paid the balance. As usual we are now running a little behind but trust we will be able to make grade before the close of the year.
I want to assure you that we want you and your daughter to keep your membership here with the Gainesville church and I am sure the whole membership feel the same way. At our next stewards meeting I will deliver your message to them and it would be awfully nice to have you back to worship with us again I am sure.
Mrs.Phifer and I greatly enjoyed your letter.I am sure you and your dear wife did your full part as pioneers and am
glad to know that many of the young men that you all helped have and are making good.
By the way, you might be interested to know that
the women of the church thru the Missionary Society have paLrobased the lot Just north of the McBeath residence on E.Main St NJand are commencing the erection of a $7500.00 brick parsonage.They have paid $2500.00 for the lot and have on hand about $2500. and have borrowed $5000.00.This is a pretty big undertaking for them under present conditions but they think they can do it and I reckon may be they can if they will just stick to it to the end.0f coursethat means about $25.00 per month interest that they must pay and it will make them hustle.
As you know we maje an effort to build a big new
church a few years ago but the boom bursted on us and we failed to get started and I guess it was a gobd thing we didn 't start as things have turned out.
tWhen you have worked as long as you feel like you
oughtamong the people over there,I trust you all will come back to lold Gainesville and be one of us during the evening of life.
Mrs.Phifer wishes to be rebered to you both.
With all good wishes,Iam, Yours sincerely,

188 Dwight Street,
Yew Haven,Connecticut,
April 15,1932.

Dear Dr. and Miss Rolfs:Please pardon the long delay in writing to you. I have diligently been searching for work ever since I returned and as yet have not been able to earn'a nickel's worth of anything. Your letter came to me this morning and I was indeed glad to receive it,and to hear of some of the things which you are doing in Brasil. I see the state of Sao Paulo is still at it in changing around state officials,none of which are able to accomplish anything constructive under the political conditions even if they cared to. I am a great admirer of Dr.Theodureto de Camargo,and I certainly* eel sorry for his position at this time.

I also judge that Dr,Mello Moraes is running true to form as of
old. He has the least appreciation of what an agricultural college is of any man I have ever met and he cares still less to ever know. Hlie also has a little characteristic of fabricating many things. I learned of some of these from some sciehtists in Sao Paulo. I never told him or anyone that I was to be at Cornell and as a matter of fact I have not been there since my return. I spent about a month at the Boyce-Thompson Institute and about the same amount of t1me here in Yew Haven near Yale University and the Connecticut Agricultural Station with Dr.Clinton. I have not even been to Chicago to see my Mother and Sister as yet as I have not been able to get enough money together at any one time to make the trip. 6u see I got my fare back to Yew York and was dropped there and not having enough money to travel I have been marroned here trying to get work af any kind ever since. I have tried ever thing. It seems impossible that the States should be in such a financial conditions There are thousands with out work and I have tried e 'y thing I could imagine to even pay for my board and room and have not been able to geta thing. Yot even washing dishes in a restaurant, Of course I have not seem Mrs.Honey but trust she is well. She is :ith her sister,in the West (Iiddle).

I have copies of the pictures taken in Sa Paulo and have already sent copies to T7r.ierberger. I have a set for you and will enclose it in this letter. I judge that the second set which you asked for was for. MTr.nierberger and as I have already sent them a set will .not have any more made up unless you wish more. I will also send a set to your sister in Florida. Should you care for more I shall be glad to supply them. They charge me 8 cents apiece for cppies.

I have communicated with scientists all oer the U.S. whooI knew
personally and have located but one possible position for next year and fear that I am not going to be able to get it. It is only an instructorship but I would take an assistantship if I cold get it,as conditions are getting worse and worse ever day. T don't believe I shall get any summer work. I tried some nurseries and farms near here while I was at one place (for about 20 25 minutes) a dozen men applied to the pro., prietor for work "nd he was not taking any. Cong-ess has killed all chance in the bureau even for summer work so that nothing is open inScibnci "ale is trying to get places for 5500 men this June and with the collegeQ and Universi-tik turning out men in June conditions will be even worse,







/ Many places that are filled now are to be dropped in June,for instance,
Hunter College in Botany Department alone is .ropping 4 Ph.D.'s in
June,cutting down the department T1any other positions are gradually being abandoned so that the unemployed is increasing and positions are,
decreasing. Congress many be trying to do a lot for unemployment but.
they have directly thrown into unemployment hundreds of trained workers.
Of course T suppose scientists are not considered "labor" and they are
only interested in "labor". I am mighty thankful to be back in the
States even though the conditions are bad. Of course if I could get
a depehdable employer I would be glael to return to Brasil for I fekl
I:cAnodooi al good there if conditions permit. I really saw so little of Brasil and was just beginning to get to the place where I could be
more useful as I had adjusted (as well as an Anglo-Saxon 'can to the
Latin mind,etc.) myself more or less to the conditions,languages,etc.

I hope this finds you ,nd the rest of the 4ne rican colony at Vigosa
well. I always am glad to hear from you and ? arn how'Brasil is progressing. The amount you sent is more than enough to cover the pictures for
I am giving a set to IIr.Dierbur& r and I expected t u at least one
set. Should you care for more I shall gladly supply them. As yet I
do not know how my pictures came out that Bert and I took in Rio. They
have been developed but hot seen as yet.

I'ust close with best wishes to all,

Sincerely yours,



Edwin E.Honev.

Faltam-lhes enthusiasm, ensinam para garantir, arenas um meio de subsistencia e disto, tudo result uma verdadeira anarchic, onde a political predomina, para criar cadeiras que so' para ella sao.de Interesse.

Nas paginas 70 do seu trabalho, na parte referente a instrucQao superior em agriculture, o Illustre amigo nao foi bem informado e Impressionado pelo number elevado de lenses, cujas cadeiras continuum sendo desdobradas, sem uma raz6o muito acceitavel, diz "que houve uma 6poca em que contava (a escola S.de A.e M.V. daqui) mais ou manos dois profess6res para cada alumni matriculado", 6 possivel que nesta march la chegaremos,_.mas, at& agora, a Escola Superior de Agricultura n&o alcanqqu
esta infelicidade.

Sou mesmo da opinion que a1gumas cadeiras, clomo a de Technologla agricola, deve cqnstituir assumpto para um unico professor, mas, o Regulamento desta Escola ast' exigindo uma reform, para que possam todos os seus, curses ter, realmente, efficiency. Ella n9o foi feita curso de agronomia 6 o que tem sido mais prejudicado.

Tive o prayer de conhecer o "ex-guia de ani-, maes dessa Escolallpaginas 85 a 87, cuja capacidade de trabalho deve server de exemplo, para os que quizerem subir pelo esforgo proprio.

Dre.HRolfs,

Vigosa, Minas Geraes.



Mau caro Dr.Rolf s:


Acabo de recebar a sua carta de 6 do corrente a foi prayer para mim recebel-a, nao s6 pelo muito qua me
merece o Illustre amigo, como por ter 6xternado conceits
sobre o ensino da chimica, queveem ao apoio das id6as
aq.ui defendidas.

Realmente, os seus dois trabalhos, qua recebi, estdo am polos oppostos, mas, no momecto actual, considerando a grande importance do ensino agricola para o'Brasil, qualquer trabalho bem feito sobre ensino agricola tem
sempre um val5r superior.

Eis ahi, o, motive unico qua considered o seu trabalho sobre ensino agricola superior ao'de "Propag&Qao do
Citrus no Brasil", cujo progress depended do primeiro.

Tenho acompanhado Illustre professor o seu traba1ho nesse Estado com especial carinho a sobre a sua carta
muito 1he poderia fallar, mas, ficara' para uma outra occasiao. Entretanto, tratarei dos pontoi principles.

Alta educaQao am chimica Sempre considered prejudicial, a id6a extravagant dengio se queer dar aos
curses de chirrica uma orientagao, mais de accord com o nos.go meio e seguindo, tanto quanto possivel, uma orientagao
technical reconhecida como b6a, no vo.L,,so adiantado paiz.

ho project qua presented aos Maus companh.eiros de Commissao para reorganizar 0 ensino da chimica no Brasil, por determinaggo do Snr4Ministro da Agricultura, o
illustre professor encontraro bemclaro o MeU ponto de





2


vista. Foi publicado no Diario Offici al e vae ser impress em folhetos.

Subscrevo todos os conceits escriptos nas paginas 2 da sua Carta. Visitaio Instituto de Chimica de B611o Horizonte e connect, tambem, o seu Director e professor.

Ngo ha duvida que "the fundamental reason for its failure however, was in the concept. The Director and the professors had projected themselves so far into the future that they lost contact with the industries of the state at the present".

Quanto A Industria de oleo de ramona ou ricino
(castor oil), que fracassou em Bello Horizonte, a causa foi exactamente a dada pelo illustre profess6r;- nada conhecia sobre extracgdo de oleo de ricino, que e uma das mais simples, e nao, achou quem a amparasse,

Na Bahia, festive com velhos amigos e colleges, oAlvaro Ramos e o Octavio Eeres, auctores da reform da Es'Cola Agricola da Bahia. Ambos estiveram nos Estados Unidos e procuraram, dentro do possivel, adopter & Escola as necessidades do Estado. A reform foi fortemente criticada aqui, pe71 10 Professor de Agricultura Geral da E.S.A. e M.V., Dr.Thomaz Coelho, e pel-o DrPaulino Cavalcatti. Delles discord em various points e espero exp6r o meu modo de pensar na Sociedade de Agronomia, quando forem discutidos os pareceres dados.

Ultimamente, visitor este Instituto o Director da Escola de Firacicaba, que esteve, tambem, na E.SA. e M.V,

Estou, perfeitamente, conheced6r do modo pelo qual. o illustre professor agiu na questao da mudanga da Escola de Agriculture daqui para Vigosa. Era Ministro o Dr.Calmon e director o.Dr.Horta, que foi substituido pelo Dr,'Famplona.

As paginas da minha Carta de 26 de margo, escrevia: "0 Brasil precise de escolas de agriculture, mas, 6 preferivel nao ter senao as capazes de ministrar, realmente, uma instruc9do agricola. e scientific elevada. Infelizmente, algumas n9o satisfazem os seus fins".

0 illustre amigo, e professor discord do meu ponto de vi-sta, talvez, por nao ter tornado bem Claro o, meu pensamento,

Condemn a existence de escolas, arenas, para dar diplomas de agronomos, sem a menor nogao pratica de agricultura e de nenhuma das cadeiras do curso. Visited as escolas de agronomia de Man6os, Belem, Fortaleza, trazendo dellas Uma pessima impressao das.suas installagoes.




3




La existed profess6res esforgados e alumnus que querem aprender, mas, nada poder&o fazer em beneficio da agriculture dos seus estados. Gonhecem agriculture, em sua maioria, pelas figures dos livros e os agricultores dos estados nao teem confianga nos seus ensinamentos.

Pernambuco tem tido, varies escolas de agriculture. Visited a annex & Escola de Engenharia, que foi depois installada em Barreiros, e a dos padres de S.Bento.

A de Barreiros foi construida para =a escola de
agriculture, mas,,foi fechada e quando 16 festive, encontreia como hospicio.

Actualmente, a dos padres de S.Bento esta' amparada pelo Estado e demonstrate, inegavelmente, um grande esforgo.

Na Bahia, a Escola Agricola estava optimamente installada. Fecharam a escola, distribuiram os apparelhos pela Escola de Engenharia e outros estabelecimentos, para mais tarde reabril-a e depois transferil-a para a capital, para ser mais tarde, talvez,-installada em Cata, onde se acha o Fosto Zootechnico, optimamente, Installado pelo Alvaro Ramos.

1h Minas, s' conhego essa Escola e a de Bello Horizonte. Ngo ha duvidaque a Escola-de Bello Horizonte demons-' tra um grande esforgo, mas, se f6sse fechada, como as do Norte, do Amazonas at& o Cearg, n&o prejudicariam ao future agricola do paiz. Salvo, se os estados ou.o governor central amparassem essas instituig6es. 0

Em Sao Paulo, F aran5 e Rio Grande do Sul (Forto Alegre e-Pelotas), visited as escolas de agriculture 1& existences e teem meios, principalmente, a de Piracicaba e .Forto Alegre para darem options curses de agriculture, apenas, precisam, em certos points adoptarem os programmes, as exigencies e o adeantamento dos estados. Soube que a Escola Agricola do Parang vae ser fechada, por falta da subvengao estadual. 0 intervenor quer crear, arenas, o ensino primario agricola.

0 grande mal que fazem essas escolas mal Installadas 6 a producqao dos I'doutores", que, muitas vezes, devido aos pistol6es, alcangam posiq&es de destaque, ficam convicts de que entendem alguma cousa de agriculture e das suas Industrias. eresolvem ditar leis, que s6 fazem prejudicar o, paiz.

As escolas devem ter elements para ensinar e obrigar o alumnor a trabalhar, theoricae praticamente, nos problemas que lhe forem apreiventados, para que possam 6aber mandar. 2 a orientaggo que deu b Illustre professor a essa Escola e 6 por isto que os seus alumnus estao sendo procurados.




4



Quanto Escola Superior de Agricultura dlaqui, o grande'mal vem desde a sua creagao.

I know that "she has some of the finest scientists of South America on her Faculty", but it Is not enough....

Na minha aula inaugural, qua darei hoje 'a tarde,
operate o Ministro da Agricultura, tratarei da actual sitLB gao do ensino, na maioria dos estados.

a Orientag&o dada ao Instituto.de Oleos e' a seguinte, temdo em vista as nossas necessidades; preparer technicos para as industries, dando-lhes os meios theoricos e praticos para resolver os problems mais communes, tendo sempre em vista o adiantamento industrial e actual do Brasil, e de crear pesquisadores, que sao escolhidos centre os melhores alumnus graduados pelo Instituto, um ou dois por anno, de accord com a verba dada, torque zao pagos'pare estudar (Fellowship Foi uma lucta para obtel-o).

Estes alumnus estudarao problems communes e necessarios ao nosso paiz e nao temos em mente, fazel-os scientistas, na concep9go real da expressao.

Felo nosso Regulamento, o Illustre professor e amiI
go vera, francamente, o nosso plano de trabalho, e sera para mim grande prayer, receber os seus conselhos a respelto.

Estimaria muito em ter a sua.visita, pois, assim melhor poderia vulgar os nossos trabalhos.

Obsequio recommendar-me a Miss Rolfs e fico

Dear Dr. Rolf a:

I was very glad to get your letter of February 22 and you will notice by this time that I have pled guilty in the inference in the next to the last paragraph of your letter. You are one of only two persons who guessed the name of the author of the Citrograph articles. Dr. E. W. Berger was the other man who guessed it correctly and in both cases it was due to the remembrance of the old article I wrote in Florida. I had considerable fun and recreation in writing these articles and I hope that
they have done no harm.

Thank you for the suggestions regarding the men who are interested in Citrus diseases in Brazil.

With best regards to yourself and daughter from all of us,9 Iam

Sincerely yours,

fDear Clarissa:

The bulletins you were so thoughtful to send came this morning, and we are delighted to have co-pies
of them in our Library.

Since the new addition to the building has been completed we have so much better facilities for taking care of material, and we are collecting everything we can find, particularly Florida material, or
by Florida people. We now have a separate room for
all Florida material, and it is kept locked except when research students go in for s-pecial work, and
then an attendant is there to help them. We seem so
much more like a library since ttie addition to our
building.

I hope you and your father are both well and I know that your work is going forward satisfactorily.
With best wishes to your father and yourself, and again
assuring you of our appreciation of the bulletins,

Cordially yours,

Dear Mr. Rolfs,

I am very pleased to acknowledge the receipt of your letter of the 16th instant and also
"Propagago do Citrus no Brasil" and "A Escola Regional
I am very grateful for the advice contained in your
letter.

From my short experience of 8 months with citrus tress, it would appear that the control of disease is the most inportant subject here and it
surprises me, at times, how trees bear at all. I only
know of one chacara where control work of any kind is
done and this is limited to liming the trunks of trees.
This can be readily understood,as without any special
care oranges give the growers a good living, the demand being greater than the supply in the local
market.

With renewed thanks and appreciation for your courtesy, I remain,
Yours very sincerely,
