“ It seems probable that these singular rodents cannot long sur- 
vive human settlement. Incapable of rapid motion they are easily 
approached, and their spiny armature, so potent a protection from 
their natural enemies, fails before the merciless power of man. In 
the isolation of the mountain top where we have just seen them, 
they appeared to be at a loss to understand the nature of their

They have now killed and burned 126 of them.” 
By persons ignorant of natural history, the Porcupine is some- 
times called “ Hedgehog.” The hedgehog is a small animal, re- 
lated to the mole, and is not found in America. 
The Porcupine makes its nest in a ledge of rocks, or in the hol-
