Note 347 — Chapter XVII

"We give here the notices which we have collected respecting the existence and position of a lake which is not to be found in any map, and which bears the name of Arapa. It is said to be 6 leagues to the north of lake Titicaca, and is 30 leagues in circumference. It extends from the foot of a very abrupt chain of mountains, and its figure is that of a half-moon. It contains some islands. Its waters, having traversed two other smaller lakes to the west, fall into the Ramiz, which is thus rendered navigable at all seasons. The principal villages around the lake of Arapa are Chacamana, Chupan, Arapa, and Vetansas. Round the latter place it is said that there are many veins of silver and mines of precious stones."—Castelnau, tom. iii. chap. xxxix. p. 420.
