 Mr. W. B. Mershon, 



Dear Sir: — 1 am much chagrined over my carelessness in overlooking your request for 

 a photo of a young Passenger Pigeon. I had best of intentions, but crowded work threw this out of 

 mind. I should have attended to it at first, had it been easy to get at the picture 1 have been 

 away all summer and found things misplaced on my return. I fear it is now too late, but send the 

 picture to be used if you are still able to do so. I shall be very much interested to see your book. 

 I still have two female pigeons and two hybrids between a former male pigeon and the common 

 Ring-dove. The hybrids are inifortunately infertile males. Very truly, 



C. O. W'hitm.an.
