Aug. 19 tli. Martins on crosstrees of flagpole, would fly 
away a moment when touched by halliards but would return at 
once. This was early this A.M. Are they preparing to migrate 
Aug. 20th. Saw young birds on box, also two or three old 
ones flying about box . 
Aug. 24th. C.saw 2 young birds flying alone over carpen- 
ter shop. These were the last seen in 1900. 
In 1901 the birds came and were here more or less during 
the season, but not in sufficient numbers to make them inde- 
pendent of the sparrows which had occupied the box and while 
we thought one pair made a nest and commenced to sit, no 
young ones were seen. 
In 1902 a few came but loss than the year before, and 
last year, 1903, none were seen. The box is still up and we 
continue to hope the birds will come. If I cduld spare the 
time, I would try the experiment again and believe with the 
advantage of the former experience I could raise a much larger 
number and make it a lasting success. 
This is the first abstract I have made of this experiment 
All that has been published, as far as I know, was a very 
short article in a 7/est Chester paper, from Mr.Hoopes, I 
think, and a mere item regarding it in one of our city papers. 
Very truly yours
