summer of 1900 in a Denver daily about January 15, 1901. I have a 
clipping only, and do not know the exact date that it was published, 
nor the paper in which it appeared. The record is as follows:

The following record, kept by an assistant, Mr. Titus, at Fort Col- 
lins last year, gives approximately the same dates at which the two 
broods of larve reach their maximum and minimum numbers. The 
dates run a little later at Fort Collins, which is the more northern 
point. The larve were taken twice a week by Mr. Titus, so some of 
the periods are 5 and some 4 days.

The first brood had reached its maximum when the bands were 
removed the first time, July 25. The great number of ciphers 
between August 11 and 22 indicate the division between the broods. 
The second maximum came September 12, and then the numbers 
diminished rather slowly for the next two weeks. 
Another record kept the same year on a tree growing in the college 
lawn at Fort Collins gave a similar record, though the first maximum 
came a few days later. The record is as follows:
