May 15 and 20. Cordley states 
that in Orei^on in 1899 moths 
emerged in some cases April 
10, and continued to do so until 
July 1. At Ithaca, N. Y., 
Slingerland found in 1896 that 
moths emerged from May 3 to 
June 22, and in 1897 from May 
21 to June T. Gillette records 
that he found moths out of 
doors at Fort Collins as early as 
April 26. The extreme range 
in time of appearance of these 
moths was 69 days in their 
cages. At Fort Collins, ac- 
cording to Mr. Hitt's records, 
this period extends over about 
23 days. Professor Slingei'- 
land found that this range was 
49 days in 1896. 
RELATION BETWEEN EMER- 
GENCE OF THE MOTH AND 
THE BLOOMING PERIOD. 
Slingerland states that the 
moths begin to emerge in New 
York about the time the apples 
are in l)loom, l)ut the majority 
do not emerge until after the 
blossoms fall, and but few lar- 
vie are found to enter the fruit 
until about two weeks there- 
after. Gillette found the first 
moth emerging about 10 days 
before the trees were in bloom. 
He states that the majority of 
them emerged about the time 
of bloom, but eggs were found 
July 9, 1900, and June 19, 
1901, and were all hatched by 
July 21, the trees having been 
in blo;gsom about May 5 to IT). 
This would make about a 
month between the ])looming 
period and the time when the
