fact, it was worthless. The difference between Plats 1 and 3, as 

 compared with Plat 2 and checks, was so marked that it could be 

 seen from a distance without going into the field. The difference 

 between Plats 1 and 3, and the portion of the field treated with 

 dry Paris green and flour was not marked until after the second 

 spraying. At the time the last examination was made a few 

 loopers had found their way from the checks to the heads on 

 Plats 1 and 3, but all the cabbage worms had disappeared. 



The following letter from Mr. F. P. Baylis gives the estimated 

 condition of the crop at time of gathering and shows the value of 

 spraying with the resin lime mixture fairly well : 



" Floral Park, K Y., Nov. 22, 1897. 



" Dear Sir: In reply to yours of the 19th inst., the white cab- 

 bage sprayed in fall of 1896 was fully 100 per cent better than 

 where not sprayed at all, and at least 60 per cent better than 

 where Paris green and flour were used. There was not so much 

 difference when used on Savoy cabbage. The sprayed was better 

 than where ' Green ' was used, but only about 30 per cent. I 

 think this is owing to the nature of the Savoy, which will make 

 quite some growth after cold weather sets in and the worms are 

 destroyed. Yours very truly, 



"F. P. BAYLIS." 



ON CAULIFLOWER AND BRUSSELS SPROUTS. 



In 1897 further tests of the resin lime mixture combined with 

 Paris green were made on cauliflower and Brussels sprouts at 

 Baiting Hollow, K Y. 



The first test was made May 26. 12 A field of cauliflower, the 

 plants of which had only 3 or 4 leaves was sprayed with 

 the resin lime mixture. At the same time seedbeds of later cauli-
