Insect Pests and Plant Diseases and How
to Combat Them, by Prof W. G. johnson
State Entomologist.
Naturalists have discovered iu the last
quarter OF a century that there is SO close
relationship and lnterdependence between
plants and insects that should the entire
class OF insects be destroyed the whole lace
Of nature would speedily change. With
the disappearance OF our grains, grasses and
succulent fruits, man and the higher ami
mails would possibly perish Everything
has place in the economy OF nature, and
it would not be good policy to ekterminate
any plant or insect. The balance Of nature
may be kept by the applcG N # insect
cides and fungicides
1t has been estimated tina there afs on
the earth 100000 species insects Nrt
all Of these are injurious, rU us0y an

and none OF the arsenicals win destroy them,
therefore, such washes as whale oil soap
and water and kerosene emulsion.
Insects do not breathe through their
mouths as do the higher animals, but
through little openings along their sides
called spiracles. Such insecticides as kero-
sene emulsion are applied as irritants, and
the insects are killed by the closing up OF
the breathing organs.
The various orders of insects were ex-
planned by means OF charts and specimens.
The internal anatomy was illustrated by a
large model of the silk worm. Each part
was taken out and explained.
1t was stated that the dreaded San Jose
scale had gained foothold in this county
and was doing much damage to young OF
chards. This neat has been located in twelve
