At the time of full sea, one half of the Penguins assemble in the centre-square, where they parade in regular order. They then march off, two abreast, and in close order, preceded by a leader, to the diving-place. They dive into the sea in succession, as they arrive, and swim off to feed on kelp, rock-weed, small fish, and other marine productions. During their absence, the other half remain stationary upon their stands, keeping watch; occasional short visits by some few of them to their nearest neighbours, being the only deviation from strict duty in this particular, that is allowed. If any one strays far from his station, or shows a disposition to go out to feed, he is pecked and driven back by the others. At the turn of the tide, those that are out collect about the landing-place; some sporting in the water, leaping and diving with great dexterity; others lounging upon the shore, apparently admiring themselves and each other, like our fashionable belles and dandies in Broadway. When the leader lands, they form in regular order, march to the square, in the same manner as they left it, divide into squadrons, and file off to their respective stations to relieve guard. As soon as those returned from feeding mount the stands, the others leap off and repair to the square. When collected, they form, and march off to the diving place in the manner before described, to take their tide of feeding and recreation. Thus they occupy the day; each having the benefit of a full tide, and each doing his share of domestic duties. At night all are assembled in the city, and each stand is crowned with two of these exemplary birds. The contemplation of these orderly, discreet, and beautiful amphibia, afforded me much pleasure, and gave rise to many delightful anticipations. It appeared certain to me that they, in common with seals, whales, and mackerel, were visiters from the internal world through the southern opening, which they were admirably formed to pass and repass; for they moved with great facility, in the water, and could exist under it as well as fish. On land they walked with as much ease as men, and in the same erect posture. It occurred to me that a world, in which the brute creation were so neatly formed, so polished in their manners, so social in their habits, and so quiet and well behaved, must, if men existed in it, be the abode of a race perfect in their kind. I had no apprehension of the air being unhealthy in the internal world as suggested by Capt. Symmes, because the climate in which these visiters are found in the greatest numbers is the healthiest of the external world, which indicates that they are accustomed to good air, or they would not affect this salubrious region.
