“And quite as large too?”
“Quite as large: the tracks of some kinds even larger than those of most men. As, for instance, the white and grizzly species—many individuals of both having paws over twelve inches in length!”
“The bear does not tread upon his toes in walking, but lays the whole sole of his foot along the ground—does he not?” asked Ivan.
“Precisely so,” replied Alexis; “and hence he is termed a plantigrade animal, to distinguish him from those other kinds, as horses, oxen, swine, dogs, cats, and so forth, that all, in reality, step upon their toes.”
“There are some other plantigrade animals besides bears?” said Ivan, interrogatively; “our badger and glutton, for instance?”
“Yes,” answered the naturalist. “These are plantigrade; and for this reason they have been classed along with the bears under the general name ursidae; but in father’s opinion, and mine too,” added Alexis, with a slight sparkle of scientific conceit, “this classification is altogether an erroneous one, and rests upon the very insignificant support of the plantigrade feet. In all other respects the different genera of small animals, that have thus been introduced into the family of the bears are, as unlike the latter almost bears as are to blue bottles.”
“What animals have been included in this family ursidae?”
“The European glutton and American wolverine (gulo), the badgers of both continents, and of Asia (meles), the raccoon (procyon), the Cape ratel (mellivora), the panda (ailurus), the benturong (ictides), the coati (nasua), the paradoxure (paradoxurus), and even the curious little teledu of Java (mydaus). It was Linnaeus himself who first entered these animals under the heading of bears—at least, such of them as were known in his day; and the French anatomist, Cuvier, extended this incongruous list to the others. To distinguish them from the true bears, they divided the family into two branches—the ursinae, or bears properly so called, and the subursinae, or little bears. Now, in my opinion,” continued Alexis, “there is not the slightest necessity for calling these numerous species of animals even ‘little bears.’ They are not bears in any sense of the word: having scarce any other resemblance to the noble Bruin than their plantigrade feet. All these animals—the Javanese teledu excepted—have long tails; some of them, in fact, being very long and very bushy—a characteristic altogether wanting to the bears, that can hardly be said to have tails at all. But there are other peculiarities that still more widely separate the bears from the so called ‘little bears;’ and indeed so many essential points of difference, that the fact of their being classed together might easily be shown to be little better than mere anatomical nonsense. It is an outrage upon common sense,” continued Alexis, warming with his subject, “to regard a raccoon as a bear,—an animal that is ten times more like a fox, and certainly far nearer to the genus canis than that of ursus. On the other hand, it is equally absurd to break up the true bears into different genera—as these same anatomists have done; for if there be a family in the world the individual members of which bear a close family likeness to one another, that is the family of Master Bruin. Indeed, so like are the different species, that other learned anatomists have gone to the opposite extreme of absurdity, and asserted that they are all one and the same! However, we shall see as we become acquainted with the different members of this distinguished family, in what respects they differ from each other, and in what they are alike.”
“I have heard,” said Ivan, “that here, in Norway and Lapland, there are two distinct species of the brown bear, besides the black variety, which is so rare; and I have also heard say that the hunters sometimes capture a variety of a greyish colour, which they call the ‘silver bear.’ I think papa mentioned these facts.”
“Just so,” replied Alexis; “it has been the belief among Swedish naturalists that there are two species, or at least permanent varieties, of the brown bear in Northern Europe. They have even gone so far as to give them separate specific names. One is the ursus arctos major, while the other is ursas arctos minor. The former is the larger animal—more fierce in its nature, and more carnivorous in its food. The other, or smaller kind, is of a gentler disposition—or at all events more timid—and instead of preying upon oxen and other domestic animals, confines itself to eating grubs, ants, roots, berries, and vegetable substances. In their colour there is no perceptible difference between the two supposed varieties—more than may be often found between two individuals notedly of the same kind; and it is only in size and habits that a distinction has been observed. The latest and most accurate writers upon this subject believe that the great and little brown bears are not even varieties; and that the distinctive characteristics are merely the effects of age, sex, or other accidental circumstances. It is but natural to suppose that the younger bears would not be so carnivorous as those of greater age. It is well-known that preying upon other animals and feeding upon their flesh, is not a natural instinct of the brown bear; it is a habit that has its origin, first in the scarcity of other food, but which, once entered upon, soon develops itself into a strong propensity—almost equalling that of the felidae.
