they are very scarce^ and I know comparatively nothing of 
their economy. I once had a glimpse of a flying squirrel 
taking a long leap from the top of one tree to the top of an-

of its existence here. Many species are indigenous to this 
continent^ but I am not aware that any others visit this part 
of Canada at leasts than those I have mentioned.
