No doubt the cubs when full-grown change to the colour of their own species; but even at all ages bears of the same species are found varying in colour from difference of climate or other circumstances.
On the continent of North America, say the naturalists, but three species of bears are found, viz the "black," the "polar," and the "grizzly." This is not certain, however, for the cinnamon bear, of which we have been speaking, is probably a species distinct from the black.

If so, there are four kinds on that continent, and, perhaps, a fifth; as the brown bear of the Hudson's Bay furriers, hitherto set down as a variety of the black, is more likely the Russian or brown bear of Europe.

It may have reached the American continent by Kamschatka, where it is a common species.
The polar bear is found only in the snowy regions that border the Arctic Ocean; and never ranges above one hundred miles from the sea.

The "grizzly," for strength, courage, and ferocity, takes the first place among the bear family--outranking even his white cousin of the north.
We shall have more to say of him by-and-bye.

The _black_ bear is our present subject; and as all that is known of the cinnamon variety goes to show that its habits are similar to those of the black, what is here said of the one may be considered applicable to both.
The black bear (_Ursus Americanus_) is said to resemble the brown bear of Europe.
