New York AGRICULTURAL EXPERIMENT STATION. 273 
Four hundred and eighty-seven cherry buds were treated of 
which 77.8 per ct. set. The total number of checks was 497, of 
which 91.7 per ct. set. While the difference in these percent- 
ages is much greater than in the case of the apples it is hardly 
Sufficient to indicate important injury by the gas. As pre- 
viously stated the somewhat unfavorable conditions under which 
the buds were grown, together with the fact that they were put 
in about two weeks late, might easily account for this difference. 
A more definite indication that the gas had little if any injurious 
effect is shown by the comparatively high percentages of buds 
set that were fumigated with .22 gram of cyanide. The 
strongest gas and longest exposure had practically no more 
effect than the weakest gas and shortest exposure. The growth 
also was in all cases equal or nearly equal to that of the checks.
