ll, almost every year, and especially in the West and South, there
is somewhere a multiplication of grasshoppers to a very injurious
degree, and it is hoped that the introduced fungus can be used in such
cases.

Persons officially engaged in searching for remedies for injurious
insects all over the world have banded themselves together in a society
known as the Association of Economic Entomologists. They are constantly
interchanging ideas regarding the destruction of insects, and at present
active movements are on foot in this direction of interchanging
beneficial insects. Entomologists in Europe will try the coming summer
to send to the United States living specimens of a tree-inhabiting
beetle which eats the caterpillar of the gipsy moth, and which will
undoubtedly also eat the caterpillar so common upon the shade-trees of
our principal Eastern cities, which is known as the Tussock moth
caterpillar. An entomologist from the United States, Mr. C. L. Marlatt,
has started for Japan, China, and Java, for the purpose of trying to
find the original home of the famous San Jose scale--an insect which has
been doing enormous damage in the apple, pear, peach, and plum orchards
of the United States--and if he finds the original home of this scale,
it is hoped that some natural enemy or parasite will be discovered which
can be introduced into the United States to the advantage of our
fruit-growers. Professor Berlese of Italy, and Dr. Reh, of Germany,
will attempt the introduction into Europe of some of the parasites of
injurious insects which occur in the United States, and particularly
those of the woolly root-louse of the apple, known in Europe as the
"American blight"--one of the few injurious insects which probably went
to Europe from this country, and which in the United States is not so
injurious as it is in Europe.

It is a curious fact, by the way, that while we have had most of our
very injurious insects from Europe, American insects, when accidentally
introduced into Europe, do not seem to thrive. The insect just
mentioned, and the famous grape-vine _Phylloxera_, a creature which
caused France a greater economic loss than the enormous indemnity which
she had to pay to Germany after the Franco-Prussian War, are practically
the only American insects with which we have been able to repay Europe
for the insects which she has sent us. Climatic differences, no doubt,
account for this strange fact, and our longer and warmer s
