“In the first place,” said Alexis, “there is the brown bear (ursus arctos). Him we might find in many parts of our own country—since he is emphatically our ‘Russian bear’; but there is also a black bear, which some naturalists say is a variety of the ursus arctos, while others believe it to be a separate species, having given to it the specific name of ursus niger—ursus ator it is sometimes called. Now, whether it be a species or only a variety, we must get a skin of it all the same—since papa has definitely expressed it so.”
“This black bear is to be found in our own northern forests, is it not?”
“Yes; it has been observed there; but more frequently in the mountains of Scandinavia: and, as we might wander through all the north of Russia without finding one, our best plan will be to proceed at once to Norway or Lapland. There we shall be certain also of finding the brown bear, and thus kill two birds with one stone.”
“Say Lapland: I should like to see the little Laps, but where next? To North America, I suppose?”
“By no means. There is a bear in the Pyrenees, and other mountains of Spain—in the Asturias especially. It is also deemed by most naturalists to be only a variety of the ursus arctos, but it is certainly a distinct species; and papa thinks so. Some naturalists would have it that there are only three or four distinct species in the whole world. They might just as well say there was but one. I think it better to follow papa’s views upon this subject, and regard all those bears which have permanent marks of distinction—whether it be in size, colour, or otherwise—as being so many separate species, however much they may approximate in habits or disposition. Why, some naturalists even call the American black bear merely a variety of our brown; and, as I said a moment ago, Linnaeus himself believed the Polar to be the same species. This is now known to be an erroneous theory. Since papa has given as much time to the study of the bears as perhaps any one else, I shall follow his theory, and regard the Spanish bear (ursus pyrenaicus it is called) a distinct species.”
“You propose, then, to go next to Spain, and kill the Spanish bear?”
“We must. Having started in a westerly course by going to Lapland, we must keep on in that direction.”
“But how about the white bear of the Alps?”
“You mean the ursus albus of Lesson?”
“Yes. To reach the Alps, where it is said to be found, we should have to recross a meridian of longitude?”
