ABIPONES, an unreclaimed nation of Indians, who inhabit the south shores of the river Bermejo, in the province of Tucuman, Buenos Ayres. This nation is said, perhaps vaguely, to have formerly numbered 100,000 souls, but was, at the last accounts, about A.D. 1800, much reduced. They present some peculiar traits, living as nearly in a state of nature as possible. The men go entirely naked, subsisting themselves by hunting and fishing, and passing much of their time in idleness or war. The women wear little ornamented skins called _queyapi_. Physically, the people are well formed, of a lofty stature and bearing, robust and good featured. They paint their bodies profusely, and take great pains to inspire hardihood. For this purpose they cut and scarify themselves from childhood; they esteem tiger's flesh one of the greatest dainties, believing its properties to infuse strength and valor. In war they are most cruel, sticking their captives on the top of high poles, where, exposed to the scorching rays of the sun, they are left to die the most horrid death. They have no knowledge of God, of laws, or of policy, yet they believe in the immortality of the soul, and in a land of future bliss, where dancing and diversions shall prevail. Widows observe celibacy for a year, during which time they abstain from fish. The females occupy themselves in sewing hides, or spinning rude fabrics. When the men are intoxicated--a prevalent vice--they conceal their husbands' knives to prevent assassinations. They rear but two or three children, killing all above this number. ABISCA, an extensive mountainous territory of Peru, lying between the Yetau and Amoramago rivers, east of the Andes, noted from the earliest times, for the number of barbarous nations who occupy it. It is a wild and picturesque region, abounding in forests, lakes and streams, and affording facilities for the chase, and means of retreat from civilization, so congenial to savage tribes. An attempt to subjugate these fierce tribes made by Pedro de Andia in 1538, failed. The same result had attended the efforts of the emperor Yupanqui. ABITANIS, a mountain in the province of Lipas, in Peru. In the Quetchuan tongue, it signifies the ore of gold, from a mine of this metal, which is now nearly abandoned. ABITTIBI, the name of one of the tributaries of Moose River, of James' Bay, Canada. Also a small lake in Canada West, near the settlement of Frederick, in north latitude 48 deg., 35' and west longitude 82 deg.: also, a lake north of lake Nepissing, in the direction to Moose Fort. It is a term, apparently derived from nibee, water, and wab, light.
