These nests were in the form of obtuse cones, and were constructed with mud, grass, and herbage. In the formation of them, the alligators had made a kind of floor of these substances, upon the ground; on this they had deposited a layer of eggs, and upon that a stratum of mortar, seven or eight inches in thickness, and then another layer of eggs; and, in this manner, one stratum upon another, nearly to the top. Mr. Bartram supposes that the eggs are hatched by the heat of the sun; and that the female alligator carefully watches her own nest of eggs until they are all hatched. He says it is certain that the young ones are not left to shift for themselves, for he had frequent opportunities of seeing female alligators leading about the shores their offspring, as a hen does her chickens. After having gratified his curiosity, he continued his voyage up the river. In his progress he observed several small floating islands. The swamps on the banks of the river were, in general, three or four feet above the level of the water; and the timber upon them was large, but thinly scattered. The black mould of these swamps was covered with a succulent and tender kind of grass, which, when chewed, was sweet and agreeable to the taste, somewhat like young sugar-canes. Alligators were still numerous. Exposed, during the day, to the rays of a vertical sun, Mr. Bartram experienced great inconvenience in rowing his canoe against the stream; and, at night, he was annoyed by the stings of musquitoes, and he was obliged to be constantly on guard against the attacks of alligators. In one instance an alligator, of immense size, came up to his tent, and approached within six feet of him, when he was awakened by the screaming owl. Starting up, he seized his musket, which, during the night, he always kept under his head; and the animal, alarmed by the noise, rushed again into the water. In many places the banks of the river were ornamented with hanging garlands of various climbing vegetables, both shrubs and plants. One of these had white flowers, each as big as a small funnel, the tube five or six inches in length, and not thicker than a tobacco-pipe. It was curious to observe the wild squash, (a species of cucurbita,) which grew upon the lofty limbs of the trees: its yellow fruit, somewhat of the size and shape of a large orange, pendant over the water. In some parts there were steep cliffs on each side of the river. During the middle of the day the weather was so intensely hot, that Mr. Bartram was obliged to seek for shelter under the shade of the trees which grew upon the banks.
