sote mixture. The creosote may be applied with a small 
swab or paint brush. In killing gipsy moth eggs in high 
trees, it is usually best to work with two men; one man to 
point out the egg clusters from the ground, another to kill 
the eggs in the trees. (Figure 10) . Creosote mixture may 
be purchased at agricultural warehouses and seed stores at 
from 50 cents to $1 per gallon, depending on the quantity." 
CATERPILLAR DESTRUCTION. 
Spraying.— "Spraying with arsenate of lead at the rate 
of 10 pounds to 100 gallons of water is very effective when 
the caterpillars are small. Any of the common hand outfits 
will suffice for the spraying of shrubs or flowering plants, 
but for use on trees a barrel pump is desirable. The poison 
should be thoroughly mixed in water and applied, if pos- 
sible, on a clear day, in such a manner as to cover the leaves 
rather slowly with a fine mist. Spraying should begin at 
the top of the trees. The work is most effective when done 
during May and early June." Where orchards are to 
be sprayed, this spraying may be combined with that which 
should always be given for the codling moth and diseases. 
Eecent experiments in Massachusetts have shown that 
woodlands can be more cheaply sprayed by using a power 
outfit with a large hose and straight jet nozzle shooting a 
large stream into the air high above the trees, which de- 
scends upon them in a spray. This does away with the 
expensive climbing and makes the work much quicker. 
More materials are used but the cost of the work can be 
reduced to about $25.00 an acre. 
Burlapping.— When a loose band of burlap or other cloth 
is tied about an infested tree trunk the caterpillars will 
gather under it in the day and may be destroyed by hand. 
The burlaps should be examined daily. But if there be 
numerous hollow stubs and loose bark on the tree, the cater- 
pillars will secrete themselves there rather than under the 
burlap, so that to make the burlap treatment effective the 
trees should be thoroughly scraped and the holes plugged
