The first of the superior varieties to fruit in 3ra-
sil. Imported by the M:inas Geraes Agricultural Col-
lege in 1925. Nurserymen have 'sold thousands of
trees budded to this variety. LNany tens of thousands
of trees budded to varieties belonging to the Gua-
temalan, Mexican and hybrids have been sold. Although
the first tree fruited only ten years ago, thousands
t crates of their fruit have already been marketed
in Brasil. One planter marketed seven thousand
crates in 1937.
Brasilians differ radically from Americans in
that the whole population, nearly fifty million,
are avocado eaters. No other large country con-
sumes so much 6f this fruit. Relatively few
Americans know an avocado when they see it. A
small percent apply the vulgarism "alligator pear".

XV. Touring in Brasil.
How to See the Usual and the Unusual
1). Tourist, Y:turlist or Sciettist.
Whether one or the other of these is merely
a matter of temperament. The tourist, whose time
is alv.ays ver' precious, demands ani pays for the
;cst,- means of transport, reals and lodging. An
a amorous flea pursing his mate :ay upset the rou-
ti n of an entire hotel staff and cause a violent
headache for the "Gerente". A thirsty bedbug may
cause a world wide scandal. The grapevine tele-
phone functions wherever two or more tourists
meet. oo censorship can stop them. No dictator
is poweri~l1 enough to proscribe them. Great. de
luxe"continental trains are run for their con-
venience; and expense. A five minute delay is
unpardonable. very day trainloads of tourists
halt at the rim of the G rand Canyon of the Colora-
do for three hours to see the incomparable spec-
tcle Rhetoricians have tarried for weeks to
v:rite under the inspiration. Poets have burst
forth in ethereal meter. Artists have taken
months to transfer their feelings to canvas.
"A naturalistt, said Bradford Torrey, ''Never
knows what he is looking for and is most delighted
when he finds it.' He maintained that everything
\ as worth observing and recording; sometime and
somewhere it will fit into nature's jigsaw puzzle.
_ __ __ _
He knew because he vrote several delightful books
on natural history. He disparaged the scientist,
because, as he said, the scientist knew just what
he was looking for and never lets up until he had
Dr. Joseph Le Conte, Professor of Geology in
the University of South Carolina, traversed afoot,
the unexplored stretches of the Apalachian Moun-
tains, carrying with him his rations, consisting
of "side meat" (bacon) and "cohn" (corn) bread.
He wrote the most delightful textbook, "Elements
of Geology", ever compiled. The great western
empire, California, had to smile and wheedle to
coax him to her University. Dr. H.S.Fawcett,
one of the most brilliant biological scientists
living, has repeatedly said, at the close of the
day's work, "By jinks, I have forgotten to eat
my lunch". And then looks up at a negro janitor,
remarking, "If I take it home my wife will be
distressed for days". Before he had a wife, he
often slept under trees where he was studying.
Imagine, if you can, a naturalist turning tourist
or the latter exchanging places with the immortal
Joseph-Le Conte. It can't be done. It is purely
a matter of the temperament of the individual.
2>. To Sete Quedas and Iguassu.
Everybody, whether tourist, naturalist or
scientist, should visit the sublime Iguassu Falls.
The tourist should go by palacial steamer from
Buenos Aires direct to the modern hotel on the
Argentine side of the River Iguassui The hotel
is equipped far entertaining tourists, including
high prices and guides to conduct parties to the
spectacular points. It will take about two days
to do the falls. (The great Niagara has been so
extensively improved that a large percent of the
visitors do both the American and Canadian Falls
in a day.
The naturalist has more leisure and so
should include both Sete Quedas and Iguassu in
his itinerary. He can take the excursion train
from S5o Paulo to Presidente Epitasio, connecting
with a steamer on the upper Parrana iver, for
Guayra, the "mate" metropolis. Here he will want
a week at least to study Pnd record nature in her
captivating and enchanting moods. The miraculous
under water explosions; Land plants and animals
adapting themselves to a perpetual mist from the
falls. The voluminous Sete Quedas, said to have
a five million horse power hydroelectric poten-
tial and to be one of the most powerful water-
falls in the world, potentially. Flocks of
noisy parrots and brilliant macaws. The three
story jungles. Presumptious tropical trees
occupying the topmost story. Gigantic bamboos,
sixty feet tall, content with the middle story.
The lowly wild orange contending with hundreds
of other species for floor space. Lianas in
every direction at every elevation, from floor
to ceiling. The fatigued naturalist regretting
that he had allow':ed himself only a week, leaves
a call at the desk. A comfortable and dainty
train carries him to Porto do I.endez, forty
miles away, at the foot of the rapids and head of
the lower Parana River. Here is another delight.
The passengers at the railway station board a
double tracked, inclined cable trolley and step
off at the ship's side.
The steamer discharges him at the city of
Foz do Iguassd, with ample but simple accomoda-
tions for normal travel. An auto road takes him
to the sublime falls; fifty feet higher than the
:iagara Falls and during high water, with a much
greater volume. The naturalist and scientist
will find the low water period more auspicious.
The former should allow himself two weeks, at '
least. Come provided with several volumes for
recording notes and a roll of his favorite film
for each day's stay. One roll should be highly
sensitive to color. A rainbow cast by the moon,
in the mist, is a rare spectacle. It will be
discounted without tangible evidence; and then
too, such a photograph would probably be the only
one extant. Or he may be so lucky as to get a
photograph of swallows diving thru the falls to
their nests behind it.
A scientist has unlimited time and infinite
patience to work out his theme. He can follow
the route of the naturalist or go to Curityba,
State of ParanA, and there hire a truck or auto-
mobile and go directly to the Iguassi Falls,
some three hundred miles west. After he has
spent two months taking notes and making expos-
ures, collecting and labelling specimens, he will
have enough material to keep him very busy for
two or three years to come.
Material for volumes and volumes of natural
history and scientific lore has been grouped
around the sublime Iguassu.
3). To Paulo Affonso Falls
In North Brasil.
The traveler, whether naturalist or scientist,
should make his first trip (the second and suc-
ceeding trips will be inevitable) to the Paulo
Affonso Falls during low water, August to Novem-
ber. Railhead from the north is at Garanhuns,
Pcrnambuco. Two hundred miles to Pedra, nearest
town to the falls. It takes two days by auto to
do it, the road is tortuous and lined with inter-
esting and important things one wants to see.
Railhead from the south is at Propria, State
of Sergipe. From Propria to Piranhas, State of
Alagoas, an hundred miles up the Sio Francisco
River, is an enchanting trip. Something truly
out of the ordinary. It is made by "canoa",
with gigantic sails. May take a day or two or
may take a week at worst if the wind is obstre-
perous. From the landing at Piranhas to Pedra,
forty miles, is a half day by auto.
Three great waterfalls, Sete Quedas,
the sublime ITuassu and Paulo Affonso.
Falls of Sete Quedas, at Guayra, State of
Parana. The falls extend for nearly a mile from
this point. Prevailing south east winds keep the
woods to the left perpetually bathed in rainfall.
Veritable fairyland for a scientist, if he don't
mind getting wet. The rain comes from above, below
and all sides. An umbrella is of no use. Either
the scientist or naturalist passes from surprise to
wnazement. Engineers say that there is a potential
of five million hydroelectric horsepower.
