APPLYING THE ‘‘PARADICHLOR.” 
After the soil around the base of the tree has been prepared the 
“yaradichlor”’ is applied evenly in a circular band an inch or two wide 
entirely around the tree, care being taken that the inner part of the 
band is about 2 inches from the tree trunk (fig. 11). Use 1 ounce per 
tree, by weight, or somewhat more for very large trees, and for con- 
venience in measuring the chemical a small bottle or wooden or tin box 
holding just the desired amount may be employed. As soon as the 
chemicalhas been applied, cover it carefully with several shovelfuls of 
dirt, making a cone-shaped 
mound around the tree 
trunk by packing the earth 
with the back of the shovel 
(fig. 12). 
IMPORTANT POINTS TO RE- 
MEMBER. 
Under average fall 
weather conditions, with 
soiltemperature around 60° 
F., or higher, most of the 
“‘paradichlor’’ under the 
soil covering will have 
evaporated in four to six 
weeks, killing from 90 to 
100 per cent of the borers. 
Cooler weather than this, 
and frequent rains which 
keep the soil more or less 
wet, will greatly retard

ditions, and in general practice if feasible, mounds should be removed 
some five to six weeks after application of the chemical, so as to avoid 
subjecting the tree further to the gas on account of danger of injury. 
From present knowledge, orchardists are taking undue risks, espe- 
cially in case of applications later than above indicated, in allowing 
the mounds to remain around the trees over winter—a practice that 
has been frequently observed. Labor arrangements should be made 
to put on the chemical at the right time for its proper evaporation. 
In large commercial operations the work could well be divided into 
sections, with the necessary number of men in each section, under 
a competent foreman, to carry it along expeditiously. One group 
of men could prepare the trees for the “‘ paradichlor,”’ another group 
apply the chemical, and the third group follow immediately to cover 
and mound the trees.
