These animals are found on the coasts of the polar regions, both to the north and south, often in extreme abundance, and are generally about five feet in length, closely covered with short hair. They swim with great vigour and rapidity, and subsist on various kinds of fish, which they are often observed to pursue within a short distance of the shore. They possess no inconsiderable sagacity, and may, without much difficulty, if taken young, be familiarized to their keepers and instructed in various gesticulations. They are supposed to attain great longevity. The female is particularly attentive to her young, and scarcely ever produces more than two at a birth, which, after being suckled a fortnight on the shore, where they are always born, are conducted to the water, and taught by their dam the means of defence and subsistence; and when they are fatigued by their excursions, are relieved by being taken on her back. They distinguish her voice, and attend at her call. The flesh of seals is sometimes eaten, but they are almost always destroyed for their oil and skins. The latter are manufactured into very valuable leather, and the former is serviceable in a vast variety of manufactures. A young seal will supply about eight gallons of oil. The smell of these animals, in any great number upon the shore, is highly disagreeable. In the month of October, they are generally considered as most valuable ; and as they abound in extended caverns on the coast, which are washed by the tide, the hunters proceed to these retreats about midnight, advancing with their boat as far into the recess as they are able, armed with spears and bludgeons, and furnished with torches, to enable them to explore the cavern. They begin their operations by making the most violent noises, which soon rouse the seals from their slumbers, and awaken them to a sense of extreme danger, which they express by the most hideous yellings of terror. In their earerness to escape, they come down from all parts of the cavern, running in a promis-cuous and turbulent mass along the avenue to the watpr The men engaged in this perilous adventure oppose no impediment to this rushing crowd, but, as this begins to diminish, apply their weapons with great activity and success, destroying vast numbers, and principally the young ones. The blow of the hunter is always levelled at the nose of the seal, where a sligh stroke is almost instantly fatal.
