LEFT LENA 454 LENINE also joins the hind limbs and tail. The membrane also unites the digits of the foot, and is hairy on both sides. The fore limbs are longer and more powerful than the hind limbs. These forms are arboreal in their habits, and make short flying leaps from tree to tree, the mem- brane acting like a parachute in sup- porting them during their flight or leap through the air. They are fruit-eaters, but also prey upon insects and birds. They are nocturnal in habits; and when at rest suspend themselves from trees by RING-TAILED LEMUR the limbs, the body and head being pen- dent. The mammary glands are four in number and are placed on the breast. All other Quadrumana possess only two mammffi. The most familiar species is the Galeopithecus volitans of Java and the neighboring islands. It measures about 20 inches in length. LENA, a river of Eastern Siberia, ris- ing amid the mountains on the N. W. shore of Lake Baikal, in the government of Irkutsk, flows first N. E. to the town of Yakutsk, where it is 6% miles wide, then N. to the Arctic Ocean, into which it falls by several mouths, forming a delta 250 miles wide. Its course is 2,800 miles in length, the area of its basin 772,000 square miles. Its chief affluents are the Vilui (1,300 miles) on the left, andtheVitim (1,400), the Olekma (800), and the Aldan (1,300) on the right. Navigation on the Lena is open from Ya- kutsk upward from May till October. During spring the waters of the river regularly overflow their banks. The Lena is a principal artery of the trade of Eastern Siberia. The riverine sand of the Vitim and Olekma yields richly in gold; salt, coal, iron, copper, and argenti- ferous lead exist. Large quantities of mammoth ivory have been found in the delta. LENAPES, LENNI-LENAPES (len'- aps), or DELAWARES, one of the Al- gonquin tribes of American Indians, which about the early part of the 16th century occupied the valleys of the Dela- ware and Schuylkill. They were, accord- ing to tradition, pre-eminent for wisdom and valor, exerting a powerful influence over the neighboring tribes from the Hudson to the Chesapeake. This influ- ence they upheld till, by the rise of the Iroquois power, they lost their ascend- ency and in a manner their independ- ence. They soon afterward removed to the banks of the Susquehanna. In 1751 they are found at Shamokin and Wyalus- ing on the Susquehanna, where they be- came exposed to the violence both of the Iroquois and the whites. The English dis- regarded their peaceful attitude (they having been taught the principles of peace and non-resistance by Penn and Zinzendorf), considering them under French influence; and the Iroquois, of- fended at their neutrality, plundered their crops and devastated their villages. In 1778 they made a treaty of amity with the United States at Fort Pitt, in which the latter agreed to build a fort for their protection, which is the origin of Fort Mcintosh. In 1795 they were parties, with the Wyandots, Shawnees, and other western tribes, in the general pacification of Fort Grenville. These were further strengthened by the treaties of Fort Wayne, in 1803, and Vincennes, in 1804; and the frontiers were unmolested till the movement of Tecumseh in 1811. They gradually continued W., stopping for a time at White river, Indiana, and afterward crossing the Mississippi, fin- ally settled on fertile tracts in Kansas, cultivating the soil, raising horses, cattle, etc., and dressing in many respects in civilized costume, the United States hold- ing in trust for them a considerable fund. They were removed in 1870 to a reservation in the Indian Territory. They were later incorporated with the Cherokees. LENCOBAN, a Russian seaport on the Caspian Sea, 130 miles S. of Baku. In the vicinity are celebrated sulphur springs. It was surrendered to Russia by Persia in 1813. LENINE, NIKOLAI, a leader of the Bolshevik government in Russia. His name is Vladimir Ilyitch Uulyanoff and he was born of noble parentage at Sim- birsk on the Volga in 1870. Taking to economics very early in life he became a
