M. de Musly afterwards informed me that the female they had thought pregnant was supplied with straw at the necessary time, but though she made a bed and rested upon it for three weeks, she did not bring forth anything; therefore the last time she brought forth she had but one, and was at the age of thirty-one years. He likewise adds, that there are brown bears on Mount Jura, in Franche-comté, and in the county of Gex, which come into the plains in autumn, and do great damage in the chesnut woods. There are two species of bears in Norway, one of which is much smaller than the other; in both there are different colours, such as dark and light brown, grey, and every shade of white, at least so says Pontoppidan; and also that they retire to the dens which they have prepared in October. Being very formidable, when wounded, three or four hunters usually go together, and as he easily kills large dogs, they use small ones, which run under his belly and seize him by the genitals; when nearly overpowered, he places himself against a tree, and throws tufts or stones at his foes, until he is dispatched. In the menagerie of Chantilly there is an American bear, with fine, soft, straight black hair, whose head is longer, and snout shorter than the bears of Europe. And M. de Bertram mentions a bear that was killed near St. John's river in East Florida, which was seven feet long, weighed 400lbs. and from which 60 Paris pints of oil were drawn. THE BEAVER. AS man becomes civilized and improved, other animals are repressed and degraded. Reduced to servitude, or treated as rebels, and dispersed by force, all their societies are dissolved, and their talents rendered nugatory; their arts have disappeared, and they now retain nothing but their solitary instincts, or those foreign habits which they have acquired by example or human education. For this reason there remain no traces of their ancient talents and industry, except in those countries where man is a stranger, and where, undisturbed by him for a long succession of ages, they have freely exercised their natural talents, brought them to their limited perfection and been capable of uniting in their common designs. The beaver seems to be the only remaining monument of that intelligence in brutes, which though infinitely inferior in principle to that of man, supposes common projects and relative views; projects which having society for their basis, and for their object the construction of a dike, the erection of a residence, or the foundation of a republic, imply some method of understanding each other, and of acting in concert.
