would Lave 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. 



A Icoho lie extract— One ounce powder, 4 fluid ounces alcohol (reper- 

 eolated). 



This killed slowly at 10 dilutions; above that was not effective. 



BENZINE. 



This was used on several iusects. Early in the season when the rapes 

 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 10 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 JSquash 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 alum in it. 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. Jn 

 every respect it was a complete failure.
