As soon as the eggs have been laid, the Indians, arriving in their canoes from all directions, with their families, build reed huts on the banks--some merely driving poles into the sand, from which to swing their hammocks. The canoes are then drawn up on the beach and thoroughly washed out, while the whole praia is covered with natives with the baskets on their backs in which they collect the eggs. The eggs are then cleansed from the grains of sand adhering to them, and emptied into the canoes, when they are trodden on by the children, much in the same way as grapes are mashed for wine-making. The canoes, when full, are left exposed to the sun's rays, and in a short time a fine clear oil rises to the surface. It is then skimmed off with shells and put into large pots, when it is boiled over the fire and becomes purified. It is next transferred to jars, and is ready for use. It is finer and clearer than that produced from olives. Meantime, any stray turtles which have delayed their departure, as frequently happens, are turned over on their backs. Holes are dug in the sand near the water, in which the young turtles are kept till required for eating. When not actually employed in picking up eggs or catching turtles, the whole population are engaged in feasting off them--an enormous quantity being thus consumed. The flesh of the animals is cut up and dressed in the shells, which serve as pots, without the danger of burning; and it is washed down with copious draughts of chica. The female turtles contain an enormous number of eggs, apparently ready to be laid during a succession of years--from the large ones covered with a white membrane, down to a confused mass resembling mustard-seeds. As it requires five thousand to fill a jar of oil, and as many thousands of jars are collected, it may be conceived what an enormous number of eggs are deposited every year. Were it not that many turtles lay in solitary places, which the Indians have not discovered, the rivers would soon be depopulated. The Indian children watch for the creatures as soon as they are hatched, and collect great numbers. Humboldt calculates that nearly a million turtles annually deposit their eggs on the banks of the Lower Orinoco. In the Amazon, already the turtles have greatly decreased in numbers; and Bates states that, where formerly he could buy one for ninepence, he could with difficulty procure them latterly for eight or nine shillings each. Every house on the banks has a little pond, called a corral, or pen, in the back-yard, to hold a stock of large turtle during the wet months, till a fresh supply can be procured in the dry season. The tracaja, or smaller kind, which lays its eggs a month earlier than the larger species, seldom lives, in captivity, beyond a few days.
