/ This plant is the ficus elastica Of
1otanists, and, although tolerably well
xnown as greenhouse. window or
decorative plant at the principal rub
Der stores, it has not so very early a
history. having boon introduced in Eu-
rope in 1915. IL is native OF the East
Indias. The plant belongs to the fig
family, all of which exclude, when
wounded. milky juice. with. of course.
a fig for fruit this one being about the
size of a cherry, and not edible. There
are not less than eighty known species
distributed over a large part of the
tropical world.
Tho India-rubber tree in its native
fields attains the size of our sycamore,
growing chiefly among decomposed
rocks and vegetable matter over the
declivities of mountains. 1t grows
very rapidly when young, reaching, it
is said, to the height of twenty-four
feet in four years, and with a trunk a
foot in diameter The well-known
lndia-rubber is the product or THIS
tree as found in India, but in South
America there are several trees FROM
which il is obtained. but the chief
American tree is the Jatropha elastica.
The name, India-rubber, came from
the discovery that tho article was use
full to remove marks of the ordinary
lead pencil, and is mentioned by DIR.
/ Priestly in his work on perspective
printed in l77O, as having just been
brought to his notice. The Indians of
America gave the name cahuchu to the
hardened juice, and from this our
word caoutchouc is derived.
The milk from which the rubber is
made is extracted by making incisions
through the bark TO the wood, at
the distance of foot from each other,
all around the trees, and even up to the
top. After one course of tapping, the
tree requires to rest fortnight, when
the process may be repeated. When
the liquid is exposed to the air it be-
comes a firm and elastic substance,
fifty ounces of pure milky juice yield
ing about fifteen of clear washed gum.
This gum used to be known by the In
dian name of caOutchOuc, veritable
jaw-brealler to the English tongue.
and yet, in our bOyhOod days, when
this now plentiful rubber was being
introduced into sundry uses, that was
its common name.
For the manifold uses to which it is
now put il is vulcanizcd. This was
the discovery of Goodyear. that at the
time made his name famous. 1t is al.
80 mixed with another product from
an Indian tree, gutta percha, intro.
duced in the arts by DR.. Montgomery
in 1913. This gum is the exact oppo-
site of rubber it being non-elastic.
The plant has large. glossy leaves,
thick. oval and pointed. 1t is quite an
attractive plant, particularly as a
/ specimen window plant, without others
near it. 1t stands the dry atmosphere

plants are not much used for propa-
eating from, but an old plant is gem
orally selected and induced TO throw
out rs many shoots as possible. In the
olden times propagation was effected
by layering or winding around moss,
or inserting a shoot through a flower
pot made for the purpose, in which the
roots formed, and afterward severing
from the parent tree. Prairie Farmer.
