The saliva with which the boa covers his prey hastens the process of decomposition; the muscular flesh thus becomes softened into such a gelatinous state, that he can force entire limbs of larger, and bodies of smaller, animals down his throat without division. The Creoles call this gigantic serpent from these circumstances, “Tragavenado,” which means “Stag swallower:” they tell fabulous stories of snakes being seen with the antlers of a stag (which it was impossible to swallow) sticking in their throats. I have several times seen the boa swimming in the Orinoco, and in the smaller forest streams, the Tuamini, the Temi and the Atabapo. It holds its head above the water like a dog. Its skin is finely spotted. It is said to attain a length of 48 feet; but the largest skins which have as yet been brought to Europe and carefully measured do not exceed 21 to 23 feet. The South American boa (which is a Python) differs from the East Indian. On the Ethiopian boa, see Diodor. lib. iii. p. 204, ed. Wesseling. [50] p. 25.--“_Using ants, gums, and earth as food._” It was a very prevalent report on the coasts of Cumana, New Barcelona, and Caraccas, visited by the Franciscan monks of Guiana on their return from the missions, that there were men on the banks of the Orinoco who ate earth. When, in returning from the Rio Negro, we descended the Orinoco in thirty-six days, we passed the day of the 6th of June, 1800, in the Mission inhabited by the earth-eating Otomacs. This little village is called La Concepcion de Uruana, and is very picturesquely situated at the foot of a granite rock. I found its geographical position to be 7° 8′ 3″ N. lat., and 67° 18′ W. long. from Greenwich. The earth which the Otomacs eat is a soft unctuous clay; a true potter’s clay, of a yellowish-grey colour due to a little oxide of iron. They seek for it in particular spots on the banks of the Orinoco and the Meta, and select it with care. They distinguish the taste of one kind of earth from that of another, and do not consider all clays as equally agreeable to eat. They knead the earth into balls of about five or six inches diameter, which they burn or roast by a weak fire until the outside assumes a reddish tint. The balls are remoistened when about to be eaten. These Indians are generally wild uncultivated beings, and altogether averse to any kind of tillage. It is a proverb even among the most distant of the nations living on the Orinoco, when speaking of anything very unclean, to say that it is “so dirty, that the Otomacs eat it.”
