poultry does not seem improbable since it is said that “ hunters occasionally 
find muskrats feeding on the bodies of waterfowl that have been shot and 
lost in the marshes.” 1

12. Zapus hudsonius (Zimmerman). Hudson Bay Jumping Mouse. — 
The writer has observed these animals on one or two occasions in previous 
years, but none were seen in 1911. 
13. Erethizon dorsatum (Linn!) Canadian Porcupine. — These animals 
have disappeared with the hardwood and hemlock forests until at present 
they are very rare. They are most plentiful in the northern part of the 
county and in southern Wexford County, where there are small islands, 
so to speak, of hemlock and hardwood isolated from the surrounding 
region by thousands of acres of almost impenetrable tamarack swamp. 
One specimen was taken. 
Museum Number 42181. Sex female. 
14. Lepus americanus Erxleben. Varying Hare. — This hare is quite 
plentiful at present, altho the numbers are slowly decreasing. It is only 
found in the vicinity of large tamarack swamps or far in the interior of 
the waste lands, where there is a large amount of second growth trees, 
especially the aspens, oaks, etc., which are invading the “pineries,” and 
then only when there is swampy or low ground in the vicinity. One 
specimen was taken by the writer in the winter of 1910-11. 
Museum Number 41764. Sex male. 
15. Sylvilagus floridanus mearnsi (Allen). Cottontail. — Cottontails are 
to be found everywhere in the hardwood habitat, in the tamarack swamps, 
and in the margins of the pine lands. Merciless persecution by hunters 
and the presence of numerous enemies do not seem able to cause any 
decrease in the numbers.

16. Felis canadensis (Kerr). Canada Lynx.— It is somewhat doubtful 
if this species is ever found at present in Osceola County, altho reports 
are occasionally started that one has been seen. There is no record on 
the books of the County Clerk of a bounty having been paid on a lynx 
within the last fifteen years. This, however, is not good evidence since 
many such specimens go to the taxidermist and not to the County Clerk.
