Dear Collins: 
I don* t know whether you are planning to come up to the 
Club meeting Friday night or not, but if you are and could come 
out for a while Friday afternoon and give Dr. Robinson and me 
the use of your experience with cameras we should be very grate¬ 
ful. We have a new micro-photographic apparatus for taking seeds 
and other small objects and we are not quite clear how to work 
it without a good deal of experimentation. It occurred to us that 
perhaps you would understand immediately how to go to work with 
it and could save us a good deal of time and trouble. If, inci¬ 
dentally, you could stay over night at my house and help us a 
while Saturday with it,it would be a great help and we should be 
glad to remunerate you for your time and services, since we want 
to get the thing started right and with as little waste of time 
and money as possible. 
Naturally, I don't want to put you to inconvenience, but 
it occurred to me that you would very likely be coming up Friday 
anyway. 
Dictated to HMB 
Very sincerely.
