Mr. Alex Wetraore, 
Corinne, Utah. 
Dear Wetraore: 
Enclosed are prints of films from Rolls 6, 7, and 8. 
Mr. Kent showed me these rolls of film and it is evident 
that something is interfering with the proper working of 
your camera. Maybe your shutter was not working right or 
the diaphram not open wide enough. The films that were 
spoiled- were all underexposed. 
As yet we have had no report on the water examinations 
but I am sending the last three along today. 
Proof of your review in the Auk has been received 
and I will carefully compare it with copy and return it. 
Very truly yours, 
■'W- mi l U. ~
