- Wright Brothers' Wind tunnel
They found that a slight curve or camber in the wing section would cause the moving air to travel farther over the top of the wing surface than along the under side. This made the air pressure greater under the wing, gave a suction effect above the wing, and caused it to rise, creating lift. They discovered that a wing section of the proper camber would counteract the weight of gravity. Thus, a wing must be so designed that, with a certain amount of air flowing around it, it would lift a certain weight. They also discovered that air flow against any surface attached to the wing would cause a resistance or drag. Hundreds of experiments in their wind tunnel with various types of wing shapes gave the Wrights a series of tables from which to design a wing that would create the lift for a designed weight. - Wright Brothers' Bicycle shop
Out in Dayton, Ohio, there were two small brothers, who dreamed, as countless other children before them had dreamed, of flying like birds through the air. Their dreams were heightened by a small toy given to them by their father, the pastor of a local church. This toy was to lead to an idea which had a profound effect on the world. You would probably call it a flying propeller. It consisted of a wooden propeller which slipped over a notched stick. By placing a finger against the propeller and rapidly pushing it up the notched stick, the propeller was made to whirl up off the end of the stick and fly into the air. The brothers, young as they were, never quite forgot this little toy as they continued to dream of flying like birds through the air. Though the brothers continued to dream of flying, they were not the kind of lads who spent all their time in dreaming. They made kites which flew a little better and a little higher than those made by the other boys in the neighborhood. They built a press to print their own little newspaper, and they dabbled in woodcuts. To carve out porch posts for their father’s home they built an eight-foot wood-turning lathe. Indeed, they were the sort of boys who caused the neighbors to say, “What will they think of next?” The brothers knew that if they ever wanted to see their dreams come true they must earn their own capital. In the early nineties America was in the midst of the bicycle craze. Everyone who could possibly afford to do so owned a bicycle of some sort and belonged to a cycle club. Being mechanically minded, the brothers did the logical thing. They set themselves up in a small bicycle shop in Dayton, next door to their home. The bicycle shop in Dayton prospered, for the brothers were careful and expert mechanics, and cyclists in need of repairs made their way to the Wright Brothers’ shop. - Wright Brothers first powered airplane
By 1903 the Wright Brothers were ready to build a powered man-carrying flying machine. Their experiments had shown them just how much moving air was necessary to create lift in such a machine. To create the needed thrust, an engine having eight horsepower and weighing not over 200 pounds had to be fitted into the machine. Such an engine was not available, so the Wrights built one in their shop at Dayton, Ohio. They were ready to ship their airplane to Kitty Hawk, N. C., in the fall of 1903. - Wright Brotherrs wind tunnel
The Wright Brothers were not only inspired mechanics (as many people still believe today) but serious scientists, working along the soundest lines. In their keen desire to know what air pressure on wings really was, they cleared a corner of their bicycle shop and built a small wind tunnel with spare lumber and an old electric fan. They built small wing sections of various shapes and experimented with them in their wind tunnel. The electric fan was used to create the moving air around the wing section. By attaching the wing sections to a supporting frame and connecting the frame with a pointer and dial, they were able to keep a record of the effect of moving air on each experimental wing section. Through their wind tunnel research the Wright Brothers discovered the four forces that control all heavier-than-air flight: lift, thrust, weight, and drag. - With horn spoon she filled her mouth with water
But if the weather was cold, we did not go to the river to bathe. An earthen pot full of water stood by one of the posts near the fire. It rested in a ring of bark, to keep it from falling. My mothers dipped each a big horn spoon full of water, filled her mouth, and, blowing the water over her palms, gave her face a good rubbing. - Winter clothing
- Winter Camp
Autumn came; my mothers harvested their rather scanty crops; and, with the moon of Yellow Leaves, we struck tents and went into winter camp. My tribe usually built their winter village down in the thick woods along the Missouri, out of reach of the cold prairie winds. It was of earth lodges, like those of our summer village, but smaller and more rudely put together. We made camp this winter not very far from Like-a-Fishhook Point. - When my sack was filled, I tied it shut and slung it on my back by my packing strap
When my sack was filled, I tied it shut and slung it on my back by my packing strap. Sacred-Red-Eagle-Wing laid some sweet smelling leaves under the sack that the juices from the ripe berries might not ooze through and stain my dress. - When a man mourned he cut off his hair, painted his body with white clay
In those days, when a man mourned he cut off his hair, painted his body with white clay, and threw away his moccasins. He also cut his flesh with a knife or some sharp weapon. Now when a man sought a vision from the gods, he wept and mourned, that the gods might have pity on him; and for this he went away from the village, alone, into the hills. So it happened, that Snake Head-Ornament, on his way to the hills, went mourning and crying past a field where sat a woman, his clan cousin, on her watch-stage. Seeing him, she began a song to tease him: He said, “I am a young bird!” If a young bird, he should be in his nest; But he comes here looking gray, And wanders about outside the village! He said, “I am a young snake!” If a young snake, he should be in the hills among the red buttes; But he comes here looking gray and crying, And wanders aimlessly about! - We’ll Enter to Win, Boys!
- we women busied ourselves making bull boats
We remained in the camp about ten days. The men would hunt until they made a kill. Then we harnessed our dogs, and all went out to fetch in the meat. To do this took us about half a day. At other times, when not drying meat, we women busied ourselves making bull boats, to freight our meat down the river. - We were fond of squashes and ate many of them
Sometimes we brought a clay cooking pot, and boiled squashes. We were fond of squashes and ate many of them. We sometimes boiled green corn and beans. My sister and I shelled the corn from the cob. We shelled the beans or boiled them in the pod. My grandmother poured the mess in a wooden bowl, and we ate with spoons which she made from squash stems. She would split a stem with her knife and put in a little stick to hold the split open. - We were clad warmly, for the weather was chill. All had robes
We were clad warmly, for the weather was chill. All had robes. I wore a dress of two deer skins sewed edge to edge; the hind legs, thus sewed, made the sleeves for my arms. I had made my husband a fine skin shirt, embroidered with beads. Over it he drew his robe, fur side in. He spread his feet apart, drew the robe high enough to cover his head, and folded it, tail end first, over his right side; then the head end over his left, and belted the robe in place. He spread his feet apart when belting, to give the robe a loose skirt for walking in. - We made our eleventh camp on the north side of the Missouri
We made our eleventh camp on the north side of the Missouri, a few miles below the mouth of the Yellowstone. Here the Missouri is not very wide, and its sloping banks make a good place for crossing. A low bank of clean, hard sand lay along the water’s edge. We pitched our tents about noon on this sand. There were about a hundred tepees. They stood in rows, like houses, for there was not room on the sand to make a camping circle. - We Hidatsas loved our good dogs, and were kind to them
Even in famine times we did not forget our dogs; but we sometimes had only soft bones to give them that had been broken for boiling. The dogs gnawed these, and so got a little food. We Hidatsas loved our good dogs, and were kind to them. - We also had a big, soft ball, stuffed with antelope hair, which we would bounce in the air with the foot
We had a game of ball much like shinny. It was a woman’s game, but we little girls played it with hooked sticks. We also had a big, soft ball, stuffed with antelope hair, which we would bounce in the air with the foot. The game was to see how long a girl could bounce the ball without letting it touch the ground. Some girls could bounce it more than a hundred times. It was lots of fun. - Waiting to bat

Having bathed my baby, Red Blossom bound him in his wrapping skins. She had a square piece of tent cover, folded and sewed along the edges of one end into a kind of sack. Into this she slipped my baby, with his feet against the sewed end. About his little body she packed cattail down. On a piece of rawhide, she put some clean sand, which she heated by rolling over it a red-hot stone. She packed this sand under my baby’s feet; and, lest it prove too hot, she slipped a piece of soft buckskin under them. Over all she bound a wildcat skin, drawing the upper edge over the baby’s head, like a hood. The hot sand was to keep my baby warm. This and the cattail down we placed in a baby’s wrappings only in winter, when on a journey. - Until I was about nine years old, my hair was cut short
Until I was about nine years old, my hair was cut short, with a tuft on either side of my head, like the horns of an owl. Turtle used to cut my hair. She used a big, steel knife. In old times, I have heard, a thin blade of flint was 60used. I did not like Turtle’s hair cutting a bit, because she pulled. - Two braves
- Turtle’s hoe was made of the shoulder bone of a buffalo set in a light-wood handle, the blade firmly bound in place with thong
Turtle’s hoe was made of the shoulder bone of a buffalo set in a light-wood handle, the blade firmly bound in place with thongs. The handle was rather short, and so my grandmother stooped as she worked among her corn hills. She used to keep the hoe under her bed. As I grew a bit older my playmates and I thought it a curious old tool, and sometimes we tried to take it out and look at it, when Turtle would cry, “Nah, nah! Go away! Let that hoe alone; you will break it!” - Turtle, I think, was the last woman in the tribe to use an old-fashioned, bone-bladed hoe
Turtle was old-fashioned in her ways and did not take kindly to iron tools. “I am an Indian,” she would say, “I use the ways my fathers used.” Instead of grubbing out weeds and bushes, she pried them from the ground with a wooden digging stick. I think she was as skillful with this as were my mothers with their hoes of iron. - Turtle and her old-fashioned digging stick
I was too little to note very much of what was done. I remember that my father set up boundary marks—little piles of earth or stones, I think they were—to mark the corners of the field we claimed. My mothers and Turtle began at one end of the field and worked forward. My mothers had their heavy iron hoes; and Turtle, her old-fashioned digging stick. - Turning an error into an out

- To eke out our store of corn and keep the pot boiling, my father hunted much of the time
To eke out our store of corn and keep the pot boiling, my father hunted much of the time. To hunt deer he left the lodge before daybreak, on snowshoes, if the snow was deep. He had a flintlock gun, a smoothbore with a short barrel. The wooden stock was studded with brass nails. For shot he used slugs, bits of lead which he cut from a bar, and chewed to make round like bullets. Powder and shot were hard to get in those days - Throw to first
Throw to first - They saw two great fires sweeping toward them over the prairie
“The third day after, they saw two great fires sweeping toward them over the prairie. The women cried out with fear. All thought that they should die. “When the fires came near, the people saw that they were the two dogs, Death and Sickness. “‘Do not fear,’ said the dogs. ‘Our hearts are not all evil. True, we will bite you, because you forgot us; but we will also live with you and be your friends. We will carry your burdens; and when we die, you shall eat us.’ - They looked very terrible, all painted with the lower half of the face black
I remember one morning, just after breakfast, I heard singing, as of a dozen or more men coming toward our lodge. I started to run out to see what it was, but my mothers cried, “Do not go. It is the Black Mouths.” My mothers, I thought, looked rather scared. We were still speaking, when I heard the tramp of feet. The door lifted, and the Black Mouths came in. They looked very terrible, all painted with the lower half of the face black. Many, but not all, had the upper half of the face red. Some had eagles’ feathers in their hair, and all wore robes or blankets. Some carried guns. Others had sticks about as long as my arm. With these sticks they beat any woman who would not help in the clean-up. - They ate it greedily. It did not seem to harm them
But, as the puppies grew up, we began to feed them raw meat. My grandmother sometimes boiled corn for them, into a coarse mush. They were fond of this. As they grew older, any food that turned sour or was unfit for the family to eat was given me for my doggies. They ate it greedily. It did not seem to harm them. - Then he arose and took my baby tenderly in his arms
My little son was ten days old the second day we were in winter camp; and, though we were hardly well settled, I found time to make ready his naming feast. Having filled a wooden bowl with venison and boiled dried green 170corn—foods I knew well were to his liking—I set it before Small Ankle. “I want you to name your grandson,” I said to him. Small Ankle ate, thinking the while what name he should give my son. Then he arose and took my baby tenderly in his arms, saying, “I name him Tsakahka Sukkee, Good Bird.” Small Ankle’s gods were birds, and the name was a kind of prayer that they remember and help my little son. - The Wright Brothers experimental glider
After a year of exhaustive study and experiments with models in their wind tunnel, the Wright Brothers were ready to experiment with a man-carrying glider. With the thoroughness that was typical of every move of the Wrights, the brothers asked the government to let them have information on meteorological conditions all over the country. By studying the weather charts they were able to find a locality where there was a continual flow of wind. This would be nature’s wind tunnel where they could test their glider day after day. Through their study of the charts they found that the wind conditions at Kitty Hawk, on the North Carolina coast, seemed to offer the best possibilities for their glider test. Orville and Wilbur Wright began their experiments with a small man-carrying glider at Kitty Hawk in 1900. From that time until 1903 they made hundreds of successful glider flights and kept accurate records of each flight. They recorded wind velocity, angle of flight, duration of flight, time of day, temperature, humidity, and sky conditions overhead with the typical Wright attention to detail. Each year the Wrights constructed new gliders which embodied principles they had discovered for themselves during their flights at Kitty Hawk. Each glider was larger and had longer and narrower wings than the one before. During the fall of 1902 the brothers recorded nearly a thousand flights in a glider with a wingspan of thirty-two feet. It had a front elevator and a vertical tail which helped to maintain lateral stability. - The wild geese had come north, but this fact alone was not proof that winter had gone
- The Voyage Home

As he lay there he heard some one riding toward him, but thought it was one of his party. It was a Sioux; and right in the midst of the song—poh!—the Sioux fired, wounding Weasel Arm in the hip. Luckily the wound was slight, and Weasel Arm sprang for the near-by woods. The Sioux dared not follow him, for he saw that Weasel Arm had a gun.” - The Manager of the team

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. - The Lodge - 2

Buffalo-Bird Woman has told us of the earth lodges of her people. They were for permanent abode. Hunters, however, camping but a day or two in a place, usually put up a pole hunting lodge. Four forked poles were stacked. - The Hunting Camp
We recrossed the river the next morning and fetched back most of the staged meat and skins, reaching camp again in the early part of the afternoon - The hunters came in
The hunters returned before evening. Son-of-a-Star was the first to come in. “I shot two fat cows,” he cried. “I have cut up the meat and put it in a pile, covered with the skins.” He had brought back the choice cuts, however, the tongues, kidneys and hams. We ate the kidneys raw. - The harness was of two pieces - a collar, to go around the dog’s neck
The harness was of two pieces: a collar, to go around the dog’s neck; and a breast thong, that was drawn across his chest and through a loop in the saddle, was lapped once or twice around one of the travois poles, and was finally carried under the dog’s body to the other pole, where it was made fast. - The game was to see how many times she could be tossed without falling
A girl now lay downward on the hide. With a quick pull, the others tossed her into the air, when she was expected to come down on her feet, to be instantly tossed again. The game was to see how many times she could be tossed without falling. A player was often tossed ten or more times before she lost her balance.59 Each time, as she came down, she kept turning in one direction, right or left. When at last she fell, the pile of weeds saved her from any hurt. - The first he put on my head; the second he handed to my sister, Cold Medicine
For nigh a week my father and my two mothers were busy getting ready the feast foods for the wedding. On the morning of the sixth day, my father took from his bag a fine weasel-skin cap and an eagle-feather war bonnet. The first he put on my head; the second he handed to my sister, Cold Medicine. “Take these to Hanging Stone’s lodge,” he said. - The day was windy and cold, and the bull skin kept the chill air from me and my babe
My husband had spread a heavy bull-skin robe over the travois basket and set me on it, with another skin folded under me for a cushion. Through holes in the edge of the bull skin Son-of-a-Star passed a lariat; and when I was seated, with my baby in my arms and my robe belted snugly about us, my husband drew the lariat, drawing the bull skin about my knees and ankles. The day was windy and cold, and the bull skin kept the chill air from me and my babe. - The Crowd went wild

The beds of the rest of the family stood in the back of the lodge, against the wall. They46 were less simply made than my father’s, being each covered with an old tent skin drawn over a frame of posts and poles. The bedding was of buffalo skins. As these could not be washed, my mothers used to take them out and hang them on the poles of the corn stage on sunny days, to air. Most of the earth lodges—at least most of the larger ones—had each a bed like my father’s before the fireplace; for this was the warmest place in the lodge. Usually the eldest in the family, as the father or grandfather, slept in this bed. - Swing and a miss

Soldiers in both armies had no scruples about supplementing their rations with whatever could be taken from surrounding farms and homes. - Suddenly the knoll began to shake
“Tell us the story,” said Son-of-a-Star. “A brave young Dakota led out a war party, of six men,” began Scar. “They came into the Chippewa country and wandered about, seeking to strike an enemy. They found deserted camps, sometimes with ashes in the fire pit still warm; but they found no enemies. “One day they came to a beautiful lake. On the shore, close to the water, was a grassy knoll, rising upward like the back of a great turtle. “The leader of the party had now begun to lose heart. ‘We have found no enemy,’ he said. ‘I think the gods are angry with us. We should return home. If we do not, harm may come to us.’ “‘Let us rest by this knoll,’ said one. ‘When we have smoked, we will start back home.’ “They had smoked but one pipe when the leader said, ‘I think we should go now. There is something strange about this knoll. Somehow, I think it is alive.’ “There was a young man in the party, reckless and full of life, whom the others called the Mocker. He sprang up crying, ‘Let us see if it is alive. Come on, we will dance on the knoll.’ “‘No,’ said the leader, ‘an evil spirit may be in the knoll. The hill may be but the spirit’s body. It is not wise to mock the gods.’ “‘Hwee—come on! Who is afraid?’ cried the Mocker. He ran to the top of the knoll, and three of the party followed him laughing. They leaped and danced and called to the others, ‘What do you fear?’ “Suddenly the knoll began to shake. It put out legs. It began to move toward the lake. It was a huge turtle. - Suddenly a Sioux warrior
Suddenly a Sioux warrior, in trailing eagle-feather bonnet, and mounted on a beautiful spotted pony, dashed down the hillside toward us, waving his bow over his head; and from our side I saw Red Hand, gun in hand, riding to meet him. As they drew near one another the Sioux swerved, and an arrow, like a little snake, came curving through the air. Red Hand’s pony stumbled and fell, the shaft in its throat; but Red Hand, leaping to the ground, raised his gun and fired. I saw the Sioux drop his bow and ride back clinging desperately to his pony’s mane. Red Hand put his hand to his mouth and I heard his yi-yi-yi-yi-yah, the yell that a warrior made when he had wounded an enemy. - Strikes-Many Woman parched ripe sweet corn, pounded it in a mortar with roast buffalo fats, and kneaded the meal into little balls
My mother’s name was Weahtee. She was one of four sisters, wives of my father; her sisters’ names were Red Blossom, Stalk-of-Corn, and Strikes-Many Woman. I was taught to call all these my mothers. Such was our Indian custom. I do not think my mother’s sisters could have been kinder to me if I had been an own daughter. Meanwhile Strikes-Many Woman or old Turtle had parched some corn in a clay pot, and toasted some buffalo fats on a stick, over the coals. Red Blossom now pounded the parched corn and toasted fats together in the corn mortar, and stirred the pounded mass into the pot with 50the squash and beans. The mess was soon done. Red Blossom dipped it into our bowls with a horn spoon. - Soldier with staff and pipe
