INJURIOUS INSECTS OF 1909 AND IQIO. 51 
This gives considerable evidence in favor of the treatment. 
Many plants died on account of lack of moisture. The loss of plants 
was divided about equally between the treated and untreated plants. 
Miscellaneous Treatments. 
On May 31st four rows of cauliflower plants were set out on 
the Station ground, one row being used as a check, the others being 
treated on June 2d, as follows: 
One row of 64 plants Dr. Franklin treated with air-slaked lime 
placed around the base of the plant about three inches in every 
direction; one row of 77 plants he treated with cotton batting 
wrapped around the base of the plant after it was set out, and being 
pushed down somewhat into the dirt and held down by the dirt 
being pressed around it. The cotton stood up from an inch to an 
inch and a half from the dirt, all the way around the plant. It 
took 8 cents worth of cotton to treat 101 plants. Another row of 
57 plants was treated with cotton batting in a similar way, and one 
row of 59 plants was treated with cotton batting and creosoted 
sawdust. The cotton was applied as in the case of the other two 
rows, and the creosoted sawdust was placed around the cotton, but 
not allowed to come in contact with the plant tissue. On June 3d 
these rows were examined, but it was found that nearly all the 
plants treated with cotton batting and creosoted sawdust were dead, 
evidently on account of the creosoted sawdust. These plants were 
removed and fresh plants were put in their places, and these were 
treated with cotton batting as soon as set out, in a manner similar 
to the other two rows treated with cotton. On June 15th the row 
treated with lime was treated again. On August gth the row 
treated with lime was pulled up, and the roots of all the plants 
examined with results as follows: Seventeen marked by maggots 
and four not marked. The check row was likewise examined on 
this date, with the following results: Thirteen marked and thirteen 
free from marks. This gives no evidence in favor of the lime 
treatment. 
The plants in the three rows treated with cotton batting were 
also examined at this time, and there was no evidence shown in any 
of the rows in favor of the treatment. It should be noted here, 
however, that the cotton batting treatment in these experiments 
did not really have a fair chance to prove its value; as English 
sparrows from the first were a great nuisance in tearing away the
