Dear Prof, East 
During the past few days I have been working 
some on photographs, and have had a chance to print the slides 
that you clisered. Please let me know how you wish to have them 
sent. It is quite likely that I shall be in Forest Hills, 
at the Arboretum, sometime during the present month, at which 
time I could take them with me if you do not want them before 
that time. 
Very truly yours,
