ABITIGAS, a fierce and warlike nation of Indians, in the province of Tarma in Peru, of the original Quetche stock. They are situated 60 leagues to the east of the Andes. They are barbarians, roving from place to place, without habits of industry, and delighting in war. They are numerous, as well as warlike; but like all the non-agricultural tribes of the region, they are often in want and wretchedness. They are bounded on the south by their enemies the Ipilcos. ABO, ABOUOR MICHABO, or the Great Hare, a personage rather of mythological, than historical note, in the traditions of the Lake Algonquin tribes. It is not clear, although probable, that he is to be regarded as identical with Manabosho, or Nanabosho. ABOJEEG, a celebrated war and hereditary chief of the Chippewa nation, who flourished during the last century; more commonly written Wabojeeg, which see. ABRAHAM, a chief of the Mohawks, who, after the fall of king Hendrick, so called, at the battle of lake George, in 1755, between the English and French armies, became the ruling chief of that nation. He was the younger brother of Hendrick, and lived at the lower Mohawk Castle. He was of small stature, but shrewd and active, and a fluent speaker. Numbers of his speeches are preserved, which he delivered, as the ruling chief of his tribe, in various councils, during the stormy era of 1775, which eventuated in the American revolution. In the events of that era, his name soon disappears: as he was then a man of advanced years, he probably died at his village. It is not known that he excelled in war, and, at all events, he was succeeded, about this time, in fame and authority, by a new man in the chieftainship, who rose in the person of Thyendanegea, better known as Joseph Brant. Abraham, or little Abraham, as he was generally called, appears from his speeches and policy, to have thoroughly adopted the sentiments and policy of Sir William Johnson, of whom, with his tribe generally, he was the friend and admirer. He was, as his speeches disclose, pacific in his views, cautious in policy, and not inclined, it would seem, to rush headlong into the great contest, which was then brewing, and into which, his popular successor, Brant, went heart and hand. With less fame than his elder brother Hendrick, and with no warlike reputation, yet without imputation upon his name, in any way, he deserves to be remembered as a civilian and chieftain, who bore a respectable rank; as one of a proud, high spirited, and important tribe. Little Abraham was present at the last and _final_ council of the Mohawks, with the American Commissioners, at Albany, in September 1775, and spoke for them on this occasion--which is believed to have been the last peaceable meeting between the Americans and the Mohawk tribe, prior to the war.
