Dear Mr. Low: 
Vm having a little difficulty with your banding summary. 
"No. birds re-trapped" means individual birds rather than total

re-traps; I gather you gave me the latter, as the number for last 
winter is greater than the number of individuals banded on both 
refuges. Again, the numbers caught in your shelter trap are 
greater than the number of individuals banded in 1939-40, but lse 
than the totail of new birds plus the re-traps which you have 
listed. 
Can you straighten me out on these points? I1d like the 
total of new birds banded in 1939-40 (which Itake to be 102 on 
the Des Iacs Rfg and 220 on the Lostwood, all banded in Feb     ), 
the number of these new birds banded in each kind of trap, 
the number of individuals from past winters which were re    pped 
in 1939-40. Did you use colored feather markers or colored bands? 
Do you know of anyone else west of the 'ississippi who is 
banding pinnates or sharptails? 
Incidentally, when the Cooperative invited M. C.  ammond to 
join, Dr. Bell wrote to ask for information concerning the 
Cooperative before approving Hammond's joining. He has'int given 
his approval yet. Should I hold your data back until I hear from 
Dr. Bell? 
Very truly yours, 
F. N. Haerstrom Jr. 
Plainfield, Wisconsin.
