It is apparent from these figures that there is considerable variability 

 in the chances of survival, depending upon the time of year at which 

 fruit is set. Fruit set in September or October is liable to be killed by 

 cold weather in January, or if set in May or June is liable to be killed 

 by hot weather in June. That which was set in the winter months was 

 repeatedly chilled by low temperatures at night and its vitality was 

 probably lowered. Fruit set in April and July appears to have the best 

 chance of survival, though these relations may vary from one year to 

 another. 



It will perhaps be more nearly correct to group the records by seasons, 

 since conditions are not necessarily confined to months.
