Frosts in New York 535 



reasons given on page 511, the risk of injurious temperatures at the height 

 of the blossoms probably is considerably less than would appear from the 

 tables. For example, the record made at Appleton, Niagara county, 

 shows that freezing temperatures occurred after May i in 14 out of 21 

 years; but a careful study of the temperature record in detail, particularly 

 in connection with the dates when the various fruits come into bloom 

 (which always must be considered), warrants the statement that fruits 

 in that vicinity were injured actually in only about 6 out of the 2 1 years, 

 and in only two seasons did the injury approach a total loss. From this 

 and other studies, it is believed that about one third the number of the 

 frosts given in the table after any date in May will approximate the actual 

 frost risk to which tree fruits are subject in a given locality.
