could be found on the whole field, nor did this salted cabbage 

 ever look any better than did the check to our tests. 



The second test was made on very late cabbage, the majority 

 of which had only five or six leaves thrown out. 

 August 29 — 1. Sprayed two rows each of Savoy and Flat DutcV. 

 cabbage with the poisoned resin-lime mix- 

 ture. 



2. Sprayed two rows eacli of Savoyand Flat Dutch 



cabbage with Bordeaux mixture. 



3. Sprayed five rows each of Savoy and Flat 



Dutch cabbage with a combined mixture of 

 resin and poisoned Bordeaux mixtures. 



Note. — Examined tests on August 31. Where No. 2 was used 

 alone found no dead worms of either cabbage-moth or of the 

 imported cabbage-butterfly. Very few live worms were found 

 on either variety of cabbage where Nos. 1 and 3 were used. Ex- 

 amined again September 4, after a heavy rain. To all appear 

 ances there is very little difference between the adhering quali- 

 ties of Bordeaux mixture and the resin-lime mixture. 



There were about five acres of cabbage in the field used. On 

 September 1 the owner of the field treated all but the one-half 

 acre on which we were testing mixtures with Paris green mixed 

 with flour. When examined September 4th no dead cabbage 

 loopers could be found where he had applied the dry powder. 

 He had, however, succeeded in killing a large number of the 

 imported cabbage- worms. On September T7 the field which 

 was sprayed August 29 was resprayed, the same substances 

 being applied to the same number of rows of each variety of 

 cabbage. When this second spraying was given no attempt was 

 made to spray the lower outside leave«. as they were still pro- 

 tected by the first spraying, at least where the resin mixtures 

 were used. 



September 29. Although after two rains there is little differ- 

 ence to be seen between the amount of Bordeaux mixture (No. 2! 

 and resin-lime mixture still adhering to the leaves, there is a 

 marked difference to be seen in the leaves themselves. The leaves
