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- 

 other, in the forest ; and I have seen one or two specimens 

 of the grey species, which had been shot. The black has 

 never fallen under my own personal observation : I know it 

 only from the report of others, but have not the least doubt 

 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 least, than those I have mentioned.
