Cauliflower plants, set out on June oth, had cotton wrapped 
around them when they were set out, so that the cotton was stuck 
down into the dirt about an inch, and above the soil about three- 
fourths of an inch. There were two rows treated in this way, the 
alternating plants being treated, on this date. In one row there 
were 70 plants, and in the other 88 plants. On August 25th the 
plants remaining in these rows were pulled up, and their roots 
examined. Out of the 164 plants, of the treated plants, only 22 
were living. The death of the plants is not to be attributed to the 
treatment, because as many check plants as treated ones died, but to 
the fact that either the plants were in pocr condition, or that they 
were not set out properly. Of the treated plants 3 were found to 
be free from infestation, and 8 had been marked by maggots. Of 
the check plants 5 were free from infestation and 6 had been marked 
by maggots. This gives no evidence in favor of the treatment. 
On June 12th and 17th two rows of cauliflowers were set out 
with cotton wrapped around them, the cotton being stuck down 
into the dirt about an inch, and above the soil about three-quarters 
of an inch, as above described. These two rows contained in all 
123 plants, alternating plants being treated in both rows. In the 
case of these two rows also there was no evidence to be found, when 
the plants were pulled up and examined, in favor of the treatment. 
On the whole it must be said that the cotton treatment was entirely 
unsatisfactory. 
Treatment with Sulphur. 
Two rows containing between them 185 plants were set out on 
June 4th on the Station grounds, and were treated with sulphur 
about the bases of their stems on the morning of June 6th. The 
alternating plants in these rows were treated, the remaining plants 
being left as checks. About half a trowelful of sulphur was used 
for each treated plant. The sulphur remained in good condition, 
unmixed with soil, as long as this experiment continued. It took 
14 pounds of sulphur for 81 plants, making this treatment rather 
expensive. On July 12th the plants in these rows were pulled up 
and examined with results as follows:

It will be noticed that many of the plants had died, apparently 
through poor condition, or on account cf being improperly set, 
rather than on account of the treatment. This experiment showed 
no evidence in favor of the treatment.
