54 INJURIOUS INSECTS OF I909 AND IQIO. 
Miscellaneous. 
On June oth a row of cauliflowers containing 86 plants was set 
out on the Station grounds, the alternating plants being wrapped 
in waxed papers about their middle portions, their roots extending 
below the paper, and the tops of the plants projecting above it. The 
paper protruded about an inch above the ground, and was wrapped 
tightly about the stalks, it having been folded befcre it was wrapped, 
so ‘that there were three or four thicknesses of the paper between 
the soil and the stalks of the plants. On August 25th the plants 
were pulled up and the roots examined and counted with results 
as follows: 
muneatc dmeererrae 6 marked, 1 uninfested. 
@hecksiaracr 7 marked, 1 uninfested. 
This gives no evidence in favor of the treatment. It will be 
observed that the majority of the checks and treated plants died for 
some reason aside from the treatment. 
On June 15th a row of cauliflowers containing 34 plants was 
set out, and all plants treated at once with hellebore decoction (see 
formula given in the Twelfth Report of the Minnesota State Ento- 
mologist, Page 136). On June 22d these plants were treated again 
as before, and also again on July 20th; the long space of time 
between June 22d and July 20th having been allowed to pass with- 
out treatment, because the maggots were at this time passing 
apparently into the pupal or adult stages, and were not active. On 
August 26th the plants were pulled up, and the roots examined with 
the following results: 
NT Catedis aoe pine ceca 13 free, 31 marked. 
@hecksy tyr .is terrane 2 free, 35 marked. 
(In another row, when set out of equal number.) 
This shows some evidence in favor of the treatment. 
Carbolic Acid Emulsion. 
A row of cauliflowers containing 58 plants, set out on June 15th, 
was treated as soon as set out with carbolic acid emulsion, made 
according to the formula given in Smith’s New Jersey Bulletin No. 
200. On June 22d this emulsion was applied again, and on July 
20th the plants were treated a third time. In this experiment as in 
the one just described, there was no treatment applied between 
June 22d and July 20th, because the maggots were not active. On 
August 26th the plants were pulled up and the roots examined, 
with results as follows:
