40 INJURIOUS INSECTS OF 1909 AND IQIO. 
cutworm was taken away from every plant in this row, except one 
or two, and in some cases as many as four were taken away from a 
single plant. It is probable that they took to ihe soot in this way 
on account of its black color, which caused it to absorb a great deal 
of heat during the day and retain it during the night. 
On June 3d a row of 81 cauliflower plants were set out, and on 
June 4th every other plant in the row was treated with a batch of 
soot dough placed around its base. The soot covered the ground 
for a distance of six inches away from the plants on every side. 
On June 22nd 27 of the plants were pulled up and examined, and on 
July 20th 34 others were examined. Of the treated plants, 17 
were found to be infested and 14 free from infestation, and of the 
check plants 12 were found to be infested and 18 free; so the 
general results of the treatment with soot were negative. 
Experiments with Lime. 
A row of cabbages, planted on May 14th, had the alternate 
plants treated on May 18th with air-slaked lime, about a trowelful 
of the lime being used around the base of each plant. This covered 
the ground around the stem of the cabbage for a radius of four 
inches. The lime having become somewhat mixed with soil by 
rains, this treatment was repeated on May 28th. On June 17th 
1q plants were pulled up and examined, and on August 20th the 
remaining 24 were pulled up and examined. The results were 
entirely negative, as many of the treated plants, as of checks, being 
found infested. 
Experiments with Carbolic Acid and Lime. 
Cauliflowers planted May 18th, belonging to Mr. Fisher, of St. 
Anthony Park, were treated on May 2oth with carbolic acid and 
lime; the formula given in the New Jersey Bulletin No. 200 being 
followed. These plants were treated again in the same way on 
June Ist, a third time on June 16th, and the fourth time on June 
26th. These plants were cultivated twice, the first time on the 28th 
of May, and the second on the 8th of June. On July 12th some 
of the plants had reached maturity, and Mr. Fisher began harvest- 
ing them. On July 14th the roots of the cut plants were pulled 
and examined, and afterward the remaining roots were cut and 
examined every few days as the harvesting proceeded; examina- 
tions and counts being made on the following days: July 16th, 
July 23d, and August 3d. After the last counting the results
