E. part of Louisiana, so called in honor of Count Pontchartrain, a minister of Louis XIV. The lake is about 40 m. long from E. to W., and 24 m. wide from N". to S. It is connected with Lake Borgne on the east by the Rigolets, a narrow winding strait, and with Lake Mau- repas on the west by the bayou Manchac. Its S. shore borders on New Orleans; and the bayou St. John, a small tributary, extends into that city. The lake is nowhere more than about 20 ft. deep, yet through it is carried on most of the coasting trade between New Or- leans and the eastern gulf ports. Steamboats and small vessels pass from the lake to the heart of the city through two canals, each ter- minating in an artificial basin. The northern shores of the lake are more elevated than the southern, and afford sites for country seats and summer resorts. Among these are the villages of Madisonville and Mandeville. P01VTE, Da.

' PONTIAC, a North American Indian, chief of the Ottawas, an Algonquin tribe, born about 1712, killed in 1769. He was first known as an ally of the French. In 1746, at the head of a body of Indians, mostly Ottawas, he suc- cessfully defended Detroit, then a French pos- session, against the attacks of some hostile northern tribes. He is believed to have led several hundred Ottawas at Braddock's defeat in 1755. The Indians at that time were fond of the French, and hated the English; their discontent was increased by injudicious usage, and trivial conspiracies began to be formed. Pontiac finally determined to concentrate the hatred of all the western tribes in one great effort to drive out the English. At the end of 1762 he sent messengers to the different na- tions, proposing that in May, 1763, they should rise, massacre the English garrisons, and fall upon the frontier settlements. The plot was generally successful. Pontiac had reserved for himself the attack upon Detroit, but before it was made his intention was discovered. He then regularly besieged the place, and neglect- ed no expedient that savage warfare could sug- gest to take it. To obtain food for his war- riors he issued promissory notes, drawn upon birch bark and signed with the figure of an ot- ter, which were all redeemed. After the siege had continued several months it was raised, and the tribes generally sued for peace. Bu1 Pontiac was not yet subdued. He endeavoi to stir up the Indians on the Miami and 11 other parts of the west, and applied for aid, though in vain, to the French commander
