pip. There are scientists devoting much
time to research in all manner of things
large and small. Their activities may be
best understood by taking look at the
tasks they are tackling.
There u.s. for instance, DIR. Rodney III.
True whose chief business it is to Juggle
with those plants that are perniciously
poisonous Dr. True has garden IN
which he grows scores of plants with
medicinal properties. In that garden may
be found the big white poppies of India
which yield the opium that has degen-
Grated the orient. This government does
not want opium grown in America ana,
in fact, guards against its introduction,
but a few of these poppieS are grown
for experimental purposes. In a bed
nearby is another medicinal plant of the
orient a sort of first love of the Chinese.
This is ginseng. Ginseng is root plant.
a sort of potato, that has always grown
wild in the dense shades of the forest
of the Atlantic SeabOard. A generation
ago the Yankees found that they could
pull up these ginseng roots and send them
to China, where the millions of the pig
tailed kingdom would carry bit of this
root in their pockets and nibble 1T upon
occasion that the inner man might De
kept fit So profitable was this industry
that all the ginseng in the United States
was pulled UP and exported. The supply
is now almost exhausted. DR.. True is
showing farmers how they can go into
the cultivation of ginseng and produce
crop similar to potatoes, which sells for
So pound. Golden seal is another drug
plant similar to ginseng which may be
grown and sold at similar prices. There
is the Dalmatian daisy from the stormy
Balkans, which furnishes the insect pow
der of the world. 1t is being grown in
this poison garden. Camphor trees are
being raised profitably beside the orange
groves of Florida as the result Of Dr.
herbs and things which have previously
been gathered from supplies grown wild
in nature are here being domesticated,
their secrets ascertained, and they are
being handed to the farmers for Guilt

drug supply of the nation to be put on
a more dependable basis than when its
raw material is gathered in the wilds-
chief of the bureau Of entomology. DR..
Howard knows more about insects
than anybody else in the world. He
knows how houseflies multiply in the
summer time and how to keep them
from doing 1T. He knows how the
Texas tick transmits fever in cattle
and how to stamp it out. He knows
how the gypsy moth got into New
England and he knows other insects
that will combat the spread of that
insects in New England by the whole
sale and 1iberating them in the gypsy
moth territory. But most strange of
all, he has developed worldwide
commerce in insects, and 1t has come
to pass that this nation is swapping
them with other nations the world
around.
The chief gypsy moth parasite is a
certain fly that is we'll known in Eu-
rope and Japan. Certain of our scien-
fists have gone to those countries,
studied these flies. captured them,
brought them to America and bred
them in great numbers. They lay their
eggs in the larvae Of the gypsy moth
and these eggs Matching into young,
devour the larvae. So is the gypsy
moth to be fought. The gad1y is a
pest that is known the world around,
and its pernicious habit of singing
animals in the heels while inserting its
eggs under their skins has resulted
In many mild-faced COW turning her

gadf1y attacks the camel similar way
in Africa.
There is a certain digger wasp in Texas
that preys upon the gadfiy. Texas is
exporting these wasps to Africa that the
