be plucked and the whole colony destroy¬ 
ed. At a later stage, spray with arseni- 
cals. 
JUNE. 
The young caterpillars of the bud- 
worms and caseworms are hatching from 
the eggs and would seem to be amendable 
to treatment with arsenical sprays. 
Though some of them must extend their 
bodies out of their encasing tubes to feed, 
and others have in a measure the habits 
of leaf miners, all consume more or less 
or the epidermis, hence can possibly be 
killed with poisons. Continue the work 
of May against webworms and the wal¬ 
nut caterpillars collect in masses on the 
trunks of the trees to moult, kill them by 
means of a burning torch or by crushing. 
A ring of “ tree tangle foot” put around 
the trunk above the mass before begin¬ 
ning the slaughter will prevent any es¬ 
caping worms from reascending the tree, 
though they may seek other neighboring 
trees and here continue their develop¬ 
ment, If necessary repeat the white¬ 
washing against the borers so as to keep 
the coating intact. 
JULY. 
Young caseworms and budworms 
working on leaves and can likely be check¬ 
ed by spraying with poisons. Because of 
copious rains in spring it may be found 
more advantageous to spray for these in¬ 
sects during the drier months of summer 
and fall. The second • brood of web¬ 
worms may be expected to put in their 
api>earance about this time. It is probably 
that a second brood of catocalas or “alli¬ 
gator worms” also appear at about this 
time, since the moths of at least one spe¬ 
cies issue in June and early July. Ex¬ 
amine the white-wash coating on the 
trunks and renew if necessary. 
AUGUST, SEPTEMBER AND OCTOBER. 
Budworms and caseworms continue 
feeding during August and part of Sep- 
ber, but usually ensconce themselves in 
winter quarters before October. The 
whitewash may need renewing in August 
but this is unlikely if cement was used 
the preceding application. The second 
brood of webworms become conspicuous 
during this period, so also does the sec¬ 
ond brood of walnut caterpillars. The 
twig girdler is busy in September and 
October laying their eggs and girdling the 
twigs in which the eggs are laid. 
NOVEMBER AND DECEMBER. 
Insects and practice about ditto as 
given for January and February. 
Inspect the roots carefully to ascertain 
if root borers are present. If any are 
found, treat with carbon bisulphide. Fill 
up all cavities in the trunk with cement, 
first cutting out all rotten wood and singe¬ 
ing the cut surface with a blast lamp to 
destroy the spores of any rot fungi that 
may be present. This will do away with 
a favorite hiding place for hibernating 
forms, such as the pupoe of the fall web- 
worm.
