a few noted exceptions. For Instance,
the eggs of that noted pestof our orchards,

may be found atthis time of the year In
compact clusters ofseYeral hundred, sur
rounding the small twigs Of apples, pear,
and other trees in our orchards. Simply
by knowing these eggs and where TO look
for them, a man may in d few hours
gather and destroy the entire brood that
would appear few months later in the
form of innumerable caterpilars, defoli-
ating the trees. Other insects are more
readily destroyed while. in the pupa or
chrysalis state. The chrysalids of tie
