As Fast As This Collects On The Surface Of The Water, It Is Taken Off And Boiled Over A Quick

Fire. This animal oil, called tortoise butter (manteca de tortugas* (* The Tamanac Indians give it the name of carapa; the

Maypures call it timi.)) keeps the better, it is said, in proportion as it has undergone a strong ebullition. When well prepared, it is limpid, inodorous, and scarcely yellow. The missionaries compare it to the best olive oil, and it is used not merely for burning in lamps, but for cooking. It is not easy, however, to procure oil of turtles' eggs quite pure. It has generally a putrid smell, owing to the mixture of eggs in which the young are already formed.

I acquired some general statistical notions on the spot, by consulting the missionary of Uruana, his lieutenant, and the traders of Angostura. The shore of Uruana furnishes one thousand botijas, or jars of oil, annually. The price of each jar at Angostura varies from two piastres to two and a half. We may admit that the total produce of the three shores, where the cosecha, or gathering of eggs, is annually made, is five thousand botijas. Now as two hundred eggs yield oil enough to fill a bottle (limeta), it requires five thousand eggs for a jar or botija of oil. Estimating at one hundred, or one hundred and sixteen, the number of eggs that one tortoise produces, and reckoning that one third of these is broken at the time of laying, particularly by the mad tortoises, we may presume that, to obtain annually five thousand jars of oil, three hundred and thirty thousand arrau tortoises, the weight of which amounts to one hundred and sixty-five thousand quintals, must lay thirty-three millions of eggs on the three shores where this harvest is gathered. The results of these calculations are much below the truth. Many tortoises lay only sixty or seventy eggs; and a great number of these animals are devoured by jaguars at the moment they emerge from the water. The Indians bring away a great number of eggs to eat them dried in the sun; and they break a considerable number through carelessness during the gathering. The number of eggs that are hatched before the people can dig them up is so prodigious, that near the encampment of Uruana I saw the whole shore of the Orinoco swarming with little tortoises an inch in diameter, escaping with difficulty from the pursuit of the Indian children. If to these considerations be added, that all the arraus do not assemble on the three shores of the encampments; and that there are many which lay their eggs in solitude, and some weeks later,* between the mouth of the Orinoco and the confluence of the Apure; we must admit that the number of turtles which annually deposit their eggs on the banks of the Lower Orinoco, is near a million. (* The arraus, which lay their eggs before the beginning of March, (for in the same species the more or less frequent basking in the sun, the food, and the peculiar organization of each individual, occasion differences,) come out of the water with the terekays, which lay in January and February. Father Gumilla believes them to be arraus that were not able to lay their eggs the preceding year. It is difficult to find the eggs of the terekays, because these animals, far from collecting in thousands on the same beach, deposit their eggs as they are scattered about.) This number is very great for so large an animal. In general large animals multiply less considerably than the smaller ones.

The labour of collecting the eggs, and preparing the oil, occupies three weeks. It is at this period only that the missionaries have any communication with the coast and the civilized neighbouring countries. The Franciscan monks who live south of the cataracts, come to the harvest of eggs less to procure oil, than to see, as they say, white faces; and to learn whether the king inhabits the Escurial or San Ildefonso, whether convents are still suppressed in France, and above all, whether the Turks continue to keep quiet. On these subjects, (the only ones interesting to a monk of the Orinoco), the small traders of Angostura, who visit the encampments, can give, unfortunately, no very exact information. But in these distant countries no doubt is ever entertained of the news brought by a white man from the capital. The profit of the traders in oil amounts to seventy or eighty per cent; for the Indians sell it them at the price of a piastre a jar or botija, and the expense of carriage is not more than two-fifths of a piastre per jar. The Indians bring away also a considerable quantity of eggs dried in the sun, or slightly boiled. Our rowers had baskets or little bags of cotton-cloth filled with these eggs. Their taste is not disagreeable, when well preserved. We were shown large shells of turtles, which had been destroyed by the jaguars. These animals follow the arraus towards those places on the beach where the eggs are laid. They surprise the arraus on the sand; and, in order to devour them at their ease, turn them in such a manner that the under shell is uppermost. In this situation the turtles cannot rise; and as the jaguar turns many more than he can eat in one night, the Indians often avail themselves of his cunning and avidity.

When we reflect on the difficulty experienced by the naturalist in getting out the body of the turtle without separating the upper and under shells, we cannot sufficiently wonder at the suppleness of the tiger's paw, which is able to remove the double armour of the arrau, as if the adhering parts of the muscles had been cut by a surgical instrument. The jaguar pursues the turtle into the water when it is not very deep.
