Weights 
From "The Life History of the Fafescent Woodchuck" by W. J.Hamilton,
Jr., p. 91 
(filed in Rodent Box): 
"Me effect of climatic conditions, such as droughts, mild winters, etc.,
must 
play some part in the animal's existence. The late summer of 1931 was noticeably

dry, indeed a drought threatened the crops and did considerable damage in
central 
New York. It was noticed, when averaging figures for a study of the rate
of growth, 
that young collected in September of 1931 averaged consistently somewhat
lighter than 
in those animals collected a year later, when copious rains and a good growing
season 
combined to make for rank growth of the food plants commonly used by this
species. 
The average weights of nine young collected during September of 1931 averaged
four 
pounds, nine ounces, while a like number, collected over the same period
a year later 
averaged five pounds, fourteen ounces."
