would have recovered had they been where they could have crawled 
away to fresh leaves. The season was so late when received that I was 
unable to give it a test out of doors with anything like satisfaction. 
Alcoholic extract.—One ounce powder, 4 fluid ounces alcohol (reper- 
colated),. 
This killed slowly at 10 dilutions; above that was not effective. 
BENZINE. 
This was used on several insects. Early in the season when the rape 
worm was plenty a large number of infested plants were sprayed with 
very unsatisfactory results. Where it was used lightly not 1 per cent. 
of worms was killed, used heavily a few more were killed, but the plants 
were also slightly injured. Tests in the field were repeated several 
times with no better results. A number of tests were made in breed- 
ing cages and there they resisted it equally as well. Of one lot, after 
being thoroughly sprayed four times in quick succession, only 16 per 
cent. died. It usually sickened the worms, but they soon recovered. 
Of the lot above mentioned two had pupated in twenty hours. Only by 
the most thorough drenching was I able to kill cabbage worms at all 
with this remedy. The injury to leaves was not nearly so great as at 
first would be supposed, and in fact only extremely heavy applications 
did any lasting injury. 
On Potato Beetle. 
Thorough spraying did not injure these at all. Leaves were not in- 
jured. 
On Tomato Worms. 
The most thorough treatment was unavailing. Leaves slightly in- 
jured. 
On Squash Bugs. 
Were not injured. Leaves slightly burned. 
On Cabbage Lice. 
These were destroyed where the spraying was thoroughly done. 
ALUM WATER. 
This was first used in solution of 1 ounce to 1 quart of water, but as 
this had no effect whatever on cabbage worms or lice a strong solution 
was made by boiling water with a quantity of alam init. Part of the 
alum crystallized out on cooling, but left the solution as strong as could 
be made. This was used very thoroughly with no result whatever. In 
every respect it was a complete failure,
