Philadelphia, Sept. 5, 1900. 
Dear Mr.Hoopes, 
One and perhaps two pairs of Martins bred in my oox this 
season, out in addition to those that bred, there were two 
or three pairs and sometimes more on and about the oox nearly 
every day and, on the 18th of August, at about dush, there 
must have been over 100 in sight at once. A few were seen 
early the next day but, with the exception of the young birds 
from my box which left on the 24th, none have been seen since, 
to know 
I would like A when your birds left so, if you have the date, I 
will be obliged if you will send it to me. I think I may say 
that the Martins have yielded to the determined effort to 
bring them here and will in future make the Zoo one of their 
summer homes. I thank you however for your offer to place 
your colony at my service again. 
Very truly yours,

Rob ' t D. Carson.
