270 RErOKT OF the DeTARTMELNT of ExTOMOEOGY of TH0 



The total number of apple buds treated as shown by the above 

 table was 1,157, of which 80.6 per ct. set. The total number of 

 checks was 1,807, of which 84.3 per ct. set. This difference is 

 too slight to indicate that the gas seriously affected the buds 

 when the unfavorable conditions previously referred to are 

 taken into consideration. 



A further evidence that the gas had no injurious effects is the 

 variation in the percentage of treated buds that set. There is 

 no relationship between the percentage of treated buds that set 

 and the strength of gas or time of exposure. 



The slight difference in growth between the treated buds and 

 the checks is not enough to be of much importance and is prob- 

 ably due largely to the late date of setting them in.
