398 Report of the Entomologists of the 



plants were found to be practically free, not only from the cab- 

 bage worm, but also from the looper. Worms from a late brood 

 of the latter were abundant on the unsprayed portions of the field. 

 As a whole, the tests on cauliflower were not as thorough nor 

 results as marked as on cabbage sprayed in the fall of 1896. This 

 was partially due to the size of the plants at time of first spraying, 

 but more to the position in which the leaves of the cauliflower 

 grow, it frequently being impossible to get the mixture on the 

 upper and inner surface of the leaves. Hence cauliflower cannot 

 be protected as well as can cabbage. Elates I to V give some idea 

 of the difference between the sprayed and the unsprayed cauli- 

 flowers, and the following letter from Mr. B. E. Goodale, on whose 

 farm the spraying was done, gives his opinion of the value of 

 spraying cauliflower : 



" Bating Hollow, K Y., Oct. 19, 1897. 



" Dear Sir: In reply will say that the last spraying did the 

 work well. I am satisfied that it would have paid me to have 

 sprayed the entire field. The worms are raising the mischief this 

 year. I do not see but very little of the mixture at this time ad- 

 hering to the leaves that I leave as a protection. You might de- 

 tect a little on the outside row of leaves. 



" I do not think it would be of any practical use to spray later 

 than we made the last spraying. 



" Yours truly, B. E. GOODALE."

ON LETTUCE. 



During the fall and winter of 1897 and 1898 the following tests 

 of resin lime mixture combined with Paris green were made on 

 lettuce in forcing house: 



On October 27 lettuce 15 in flats was sprayed with resin lime 

 mixture and Paris green, using same strength as used on cabbage 

 and cauliflower. Cabbage loopers were collected from cabbage in 



IB This lettuce had from 3 to 4 leaves at time of spraying.
