Mr. Alex Wetmore,

Corinne, Utah. 
Dear Wetmore: 
Under separate cover six rolls of 3A films are being sent to 
you today, these being all on hand at the present time. Mr. Kent 
tells me that all of your negatives up to date have been greatly 
over-exposed, and suggests that you either reduce the time or use 
a smaller diaphragm. He will be able to get prints from negatives 
thus far received, but with difficulty. 
Mr. Holt has been asked to Join a prairie dog party in South 
Dakota, and to collect certain material for an exhibit at the Dry 
Farming Convention, Denver, Colorado. Please let us know well in 
advance of the time you wish him to Join you on the duck work. 
Very truly yours.
