Do certain individual birds come and go over the same 
migration routes ? 
How long do birds live ? etc., etc. 
The Biological Survey is now considering plans to secure 
the permanent co-operation of Universities, Colleges and 
Agricultural Schools throughout the country in Bird 
Banding, and when plans have been developed more defi- 
nitely and a larger number of organizations and individuals 
have become enrolled in this effort, the volume of data and 
results should accumulate rapidly. 
I take this opportunity to solicit volunteers in Massachu- 
setts and in New England to undertake this work with the 
ultimate purpose of forming a Bird Banding Association to 
meet regularly, to forward and systematize this work. Will 
you join ? 
Bands, record blanks, licenses, books of instruction and 
literature will be furnished free by the Biological Survey. 
As a result of only 10 weeks activity at Cohasset this 
year and with but one trap the writer was able to trap and 
to band from nests 75 birds representing 15 species. 
A good many people have answered this letter stating 
that they were interested, but had no time for trapping and 
banding. If your time is limited the only requirements of 
this association to become a member is to band ONE 
BROOD OF FLEDGLINGS per year and as many more as 
your time will permit. Therefore anyone interested can heïy 
the cause by devoting only a few hours time each year to 
this work. 
I quote from a letter recently received from J. T. Nichols, 
Assistant Curator of the American Museum of Natural His- 
tory, New York City. “T consider the work of this proposed 
Association the most important of any Ornithological 
research work in America at present.” 
If you are interested in this plan and would like further 
data, write either to the Bureau of Biological Survey at 
Washington, D. C., or to the undersigned. 
Vours very truly,
