For cover buffalo skins, bound together at the edges, were drawn around the frame in two series, the lower series being laid first. The peak of the pole frame was left uncovered, to let out the smoke. Instead of buffalo skins, gunny sacks may be used, fastened at the edges with safety pins or with wooden skewers; or strips of canvas or carpet may be used. Three or four heavier poles may be laid against the gunny-sack cover to stay it in place. The door may be made of a gunny sack, hung on a short pole. Indians often raised a piece of skin on a forked pole for a shield, to keep the wind from driving the smoke down the smoke hole. Figure shows the finished lodge with gunny-sack cover, door, and wind shield. The last is made of a piece of oil cloth. - square divider

- Lilienthal's Experiments
Lilienthal was fascinated by the mechanism of the bird’s wing. He and his brother built one machine after another to determine the exact amount of lifting effort that a man could obtain by imitating the wing-beat of a bird. One such apparatus is illustrated. This had a double set of wings; a wide pair in the centre and narrower ones in front and at the rear. These wings beat alternately, by movements of the operator’s legs; and the machine was suspended by a rope and pulleys from a beam, being counterbalanced by a weight. The tests showed this: that, after some practice in working the wings, a man could raise with them just half the weight of himself and of the machine; but the muscular effort proved so great that he could only maintain this rate of wing-beating for a few seconds. Here, incidentally, a fact may be mentioned: the energy a man can produce, at all events for a prolonged effort, has been estimated at about a quarter of a horse-power; and this—in tests so far made—has been insufficient for the purpose of wing-flapping flight. - William Penn
William Penn and the Settlement of Pennsylvania Among the most prominent was William Penn, who was born in London in 1644, the son of Sir William Penn, a wealthy admiral in the British Navy. Conspicuous service to his country had won him great esteem at Court, and he naturally desired to give his son the best possible advantages.
