Soon after coming to Florida my interest was awak-
ened in the cassava plant. The plant has been studied
somewhat carefully. It has been planted to some extent
at Lake City,and in smaller quantiy at De Funiak Springs
and Fort Myers. The evidence is strongly in favor of its
great value as a food for all kinds of stock, and as
a source for the production of starch, glucose and tapioca.
While it has long been cultivated in Florida, the fact that
it is usually grown on a rather small scale, and that
a great many farmers do not grow it all, indicate that its
worth is not fully appreciated. Moreover, many new
comers are quite unacquainted with it, and will be inter-
ested in learning of its culture and value.
A dry, loamy soil is best adapted to this plant. A
rich soil gives good returns, but the plant does well on a
light, sandy soil, if moderately fertilized. It will thrive on
almost any of the high pine land of Florida. The very
long, fleshy roots would probably not do well in a stiff,
clay soil. It is useless to plant it on springy, wet soils.
Muck lands, if well drained, will produce a crop, but not
as good a one as high pine lands with some fertilizer.
Any decomposed barnyard manure will be helpful.
Leaf-mold from the woods, decayed rubbish from the
fields, a compost of one-half good stable manure and one-
half good muck, four tons per acre will be valuable. On
our land at Lake City I have used 300 pounds per acre
of a mixture made up of 300 lbs nitrate of soda, 400 lbs
cotton and meal, 800 lbs superphosphate, 500 lbs muriate
of potash, applied in the drill, and well worked in. Al-
most any of our high pine lands will yield 6,000 to 8,000
pounds per acre of cassava, without any' fertilizer at all.
It will be more economical to give fertilizer and get 12,-
000 to 16,000 pounds per acre.
In the latitude of Lake City, cassava has a season
long enough to bloom and ripen some seed. This takes
a season of about nine months without frost. In the
neighborhood of Fort Myers it will doubtless ripen a large
quantity of seed every year. The matter of. bloom, and
of ripe seed from it, is of no importance, except as it in-
dicates a long season in which the fleshy roots may grow,
for the seed produced from the bloom is not usually
planted, unless, as in the case of the potato, one desires to
produce new varieties. Cassava, like sugar cane, is usu-
ally grown by planting the tops or canes. These branch
irregularly, and have many knots or protuberances, and
also "eyes" or buds, from which new plants spring.
These canes are bankedin the fall so as to be kept from
frost. About the tenth of March, in North Florida, they
are taken from the bank, cut into pieces six to eight
inches long, with several eyes or buds to the piece, and
these pieces are planted very much as we plant Irish po-
tatoes. In cutting the seed be careful that the pieces are
not split or shattered.
PREPARING THE SOIL AND PLANTING.
The soil should be well plowed, as for corn or pota-
toes. Lay off the rows four feet apart, and the hills four

Canaigre belongs to the same genus of plants as the
common dock which is so abundant in some parts of the
States. It grows wild in Arizona, New Mexico, and some
other sections of the great Southwest. Its leaves grow in
a cluster at the surface of the ground. They are light
green in color, quite succulent, and may be boiled for
"greens" like the leaves of the yellow dock. On pine
land here in Florida it throws up a flower-spike of two to
two and a half feet high, and produces an abundance of
seed. Its roots when young are yellowish-red outside,
and darker red within; they are shaped somewhat like a
sweet potato, tapering at both ends. As the roots grow
older they become darker in color. These roots are very
rich in tannic acid. In the Southwest the wild roots are
gathered in large quantities, are sliced, dried in the sun,
and shipped to markets in the East or to Europe, to be
used for tanning. Near localities where large quantities
of the wild roots grow, factories have been built, in a few
instances, to extract the tannin from the roots. The
tannin is then shipped in barrels to the markets, thus
making a great saving in the cost of transportation.
Attention has been turned within a few years to the
cultivation of Canaigre, and large plantations of it are al-
ready planted, and many others are planned and will soon
be planted. It can be grown from seed; but, usually,
wild roots are obtained and planted. As the roots in-
crease somewhat rapidly, the planting of roots has thus
far been the best way of starting. Should the demand
for the plant increase rapidly it will, doubtless, be easily
grown from seed on a large scale. If grown from seed,
probably the best way will be to sow the seed about as
onion seed is sown, cultivate carefully for a year, and then
transplant to the fields.
In the spring of 1894 I obtained a few roots through
the courtesy of the Directors of the Experiment Stations at
Mesilla Park, New Mexico, and Tucson, Arizona. These
came to me by mail. They were small, dry and wrinkled,
having little appearance of life. They were planted in
rows three feet apart, and two feet apart in the rows.
About a shovelfull of stable manure was given each root.
They grew at once, gave some bloom, and seemed in all
respects healthy and at home. The seeds were ripe about
the middle of May, and soon after the leaves turned yel-
low and died. Through the summer there was no sign
of the plants above ground, but the roots seemed all right.
In the fall of 1894, in October, the leaves again
appeared, and grew well all winter. The freezes cut them
somewhat, but they recovered immediately, and made a
good growth. Again, after the seed was ripe in May, 1895,
the plants died to the ground. Examination showed the
roots in healthy condition, the old ones increased in size,
and many new ones formed. In October, 1895, the
growth begun again, and now (February, 1896,) the plants
are looking well. There are a good many small roots,
about the size of the thumb. The old roots are much
larger, and of a much darker color. The ground has
been kept free from weeds, and a shovelful of manure
given once a year.
There is every promise that this plant will grow well
in Florida. The roots have a very acrid taste, indicating
that they are well charged with tannic acid. We have in
Florida great quantities of saw palmetto, the roots of
which are rich in tannin. It would be well to be quite
sure that it is more profitable to cultivate Canaigre, as a
source of tannin, than to secure it from the saw palmetto,
before going extensively into the growth of Canaigre.,
Why not establish factories to extract the tannin from
The Florida Experiment Station has only a few roots
of Canaigre. It has none for sale, or to give away. Prob-
ably any one who desires to try the plant can learn the
names of parties from whom roots can be obtained by ad-
diessing the Directors of the Experiment Stations in Ari-
zona and New Mexico.
Several sowings of Alfalfa seed were made in the fall
of 1894 and the spring of 1895. It was sown on sandy
land, fertilized with 350 pounds per acre of the following
Acid phosphate, . . .. 150 lbs.
Sulphate of potash, ...-100 lbs.
Cotton-seed meal, . . .. -100 lbs.
As the main purpose was to learn if Alfalfa would
thrive at all, the seed was sown in drills, so as to be able
to keep it free from weeds, and give it every chance to do
well. The seed germinated quickly. The young plants
were quite tender, easily cut down by frost. But the seed
sown so late that the plants were not touched by frost
grew well. By July it was twelye to fifteen inches high,
with a healthy look, A part of it was mown, and a part
left uncut. During the summer and fall the plants nearly
all died. This spring only a few roots show any sign of
life. Perhaps on other soils in Florida it may do better.
Thus far it gives no promise here.
FLAT PEA,.-(Lathylus silvestris.)
Great claims are made for this plant as a forage crop.
I grew it at the Experiment Station in Michigan with
success. In the spring of 1894 seed were procured and
sown on our Station farm at Lake City. It germinated,
but as soon as it appeared above ground it died. Apparently
it was killed by the sun.
In the fall of 1894 and the winter of 1895 several
sowings were made. The seed grew well whether sown
early or late. The earliest sowings were three or four
inches high when the severe freeze of December, 1894,
came. The plants were not killed, but during the colder
portion of the winter they made very slow growth.
Plants from seed sown February 1st were as large inMay
as were those from seed sown in the previous October. In
late spring and early summer the plants grew slowly, and
gave little promise. In mid-summer, and later, they
turned yellow and withered. All died. By November
not a plant was alive.
In the spring of 1895 I obtained a few roots of this
plant from Michigan and a few from Nebraska. Good
care was given them, and they grew well; looked healthy.
But during the winter just passed they grew very little,
and now (February, 1896), some of them are dead, and
others look as if preparing to follow their dead compan-
ions. Many dealers in seeds now offer the seed of this
plant, and anyone wishing to try it can probably procure
seed through them. It would be well to try the plant on
some of the soils of West Florida. Its forage has a very
high feeding value, and it yields heavily when it grows
well. It is a perennial. Once established it would con-
tinue indefinitely. It is a misfortune that it does not
seem to be at home on our soil and in our climate.
In the spring of 1894, when so much was said in the
agricultural press about this new forage plant, I sent for
some roots of it. They grew at once, with no special care.
After a few months the party of whom I bought wrote that
he had been misled by a dealer, and had not sent me the
true scahaline. In the spring of 1895 some true roots
were obtained. These grew well, though not with special
luxuriance. But they formed the most astonishing mass
The young stems are very vigorous and succulent.
When two or three feet high the stems begin to get woody,
but still are readily eaten by all kinds of stock. Probably
they should be cut for green forage before the stems have
become too woody. The foliage was killed by the first
frosts. The new gA h showed above ground February
20. The new shoots are very numerous. Examination
of the roots at different times during the winter had
shown that they were thickly set with buds.
It is clear that this plant once established will be very
difficult to eradicate. But it produces a large amount of
foliage which is eaten by stock with avidity. If the foli-
age proves to have a high nutritive value for animals, a
grower having a field of it would not want to eradicate it.
On most farms there are locations that could be profita-
bly given to a plant that required no attention, and that
would yield a fair amount of stock food. The permanent
value of this plant remains to be proven. Those liking
to experiment might secure a few plants and try it in
locations from which they will not want to dislodge it.
Most of the nurseries now offer for sale both plants and
