INJURIOUS INSECTS OF I909 AND IQIO. 45 
Treated, 75 entirely free, 48 infested. 
Check, 20 entirely free, 113 infested. 
This count, however, does not tell the whole story, as among 
the infested plants those which had been treated were much less 
infested, and much cleaner in appearance than were those which 
had been untreated and were infested. 
On June 18th the experiment was tried of dipping the middle 
portions of cauliflower plants in melted tanglefoot, and then drop- 
ping them in water, and afterward setting them out in the field, it 
being thought that possibly this method would be the best means 
of applying the tanglefoot, as by this means very little tanglefoot 
would be used, and it could be kept entirely away from the leading 
leaves. It necessarily, however, got down nearer to the roots by 
this method of application. In addition in some cases cheap cotton 
batting was wrapped around the tanglefoot on these plants, as it 
was thought the cotton might prove an added barrier to the mag- 
gots, and at the same time make the operation of setting out less 
objectionable. 
In these tests practically all of the treated plants died, while 
most of the check plants survived; and, in the case of the treated 
plants which survived, there was not much evidence in favor of the 
use of this treatment against the maggots. 
Experiments with Soot, 
Cauliflower plants set out May 14th were treated on May 18th, 
by placing a trowelful of dry soot around the bases of the plants. 
This covered the ground about the stem for a radius of about five 
inches. As the soot had become more or less blown away by the 
wind, and mixed with dirt by rains, another application similar to 
the first was made on the 28th; and, as this had become badly 
mixed with dirt by June 2d, a lot of soot was mixed up with water, 
and the soot dough was applied around the bases of these plants. 
Twenty-seven of the plants in this experiment were pulled up and 
examined on June roth, and 16 were pulled up and examined on 
June 15th. Out of the total of 43 plants, 38 were found to be 
more or less infested by maggots, which shows that this treatment 
was not at all effective. Further than this, it was found that the 
plants in this row were badly troubled by cutworms; much worse 
than were other rows of cauliflowers treated differently. The cut- 
worms seemed to like to work into the soot, and they were found 
imbedded in the soot in a large number of instances. At least one
