one except a wolf could tell under which piece of meat it was 
placed, and yet in the morning ever y piece of meat was gone 
except the one hanging over the trap ; various other plans 
were tried, with the same want of success, until the trapper 
found that all attempts to catch these animals were useless, 
and he therefore gave up the trial. 
The Dusky Wolf, a variety of the common wolf, frequents 
also the same region, but is far less numerous, much larger 
than the Prairie-wolf, and is remarkable for emitting a strong 
odor. 
The Black Wolf, another variety, has been found in 
British America, but is very rare ; it was also seen in the 
Bocky Mountains by Long’s expedition. Desmarest thinks 
it a distinct species from the European, but not enough is 
known of it to form any decision.
