- Physiographic provinces of Illinois
Physiography is the study of the creation and gradual change of land surface forms (the landscape). Thus, the land surface as we see it today in each of the physiographic provinces has had a particular history of development.

A One-hand catch - 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. - 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. - 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 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. - 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. - Octave Chanute experimenting with his gliders on the Michigan sand dunes
Octave Chanute, born in France and reared in America, was one of the first men to make a scientific approach to the problem of flying machines. A thorough scientist, he had followed the progress of all flight experiments the world over. He built gliders with one, two, and even five pairs of wings and tested all of them on the sand dunes of Lake Michigan. His most successful glides were made with a biplane glider. In 1894, he published a book called Progress of Flying Machines, which covered all the efforts of men like himself who had experimented with man-carrying gliders and flying machines. - J C Coleman

- Noiseless Pulley-weights
... a sketch of a pair of pulley-weights recently made, designed by Dr. Sargent, which are excellent. Their merits will be seen at a glance. Instead of the weights swaying sideways and banging against the boxes, as they are liable to do in the ordinary old-fashioned pulley-weight boxes, they travel in boxes, A A, between the rods B B. A rubber bed also prevents the weight from making a noise as it strikes the floor, while another capital feature is the arrangement of boxes, in which you may graduate the weight desired by adding little plates of a pound each, instead of the unchanging weight of the old plan. - Appliance for developing the Sides of the Waist
If one prefers to use apparatus made specially, the cut shows a simple device of Dr. Sargent's, which he made purposely to bring up and strengthen these muscles. Standing in front of it, with head and neck erect and chest out, and grasping the ends of the bar A A', the operator simply turns it, first well up to the right, then to the left, and then repeats the movements until he has enough. As he turns, the rubber straps B B stretch more and more, of course getting stiffer the farther the bar is turned. It would scarcely be possible to hit upon a [p.218]better appliance for improving these valuable side muscles, and yet without fear of overdoing them. - A Correct Position for Fast Walking
- Device for developing the Abdominal Muscles
The latest invention purposely for these muscles is also one of Sargent's, on the following plan: The pupil lies on the plank A A', or, rather, sits on it, when A' is a little back of vertical, so as, for instance, to form with A the angle A B A'. With feet in the toe-straps C C', he sways gently forward and back as long as he can without fatigue. From day to day, as these muscles gain strength, A' is dropped lower and lower, until finally it is on a level with A. Or a strap may be placed over the forehead and fastened to A', and, with the feet in the toe-straps, the person may lift his body up till vertical, drawing the weight E with him as he rises. - A Chest-deepener
Again, to deepen the chest from front to back, he hangs two bars, B and C, and attaches the weight at the other end, A, of the rope, the bar B, when at rest, being about a foot above the height of the head. Standing, not under B, but about a foot to one side of it, and facing it, grasp its ends with both hands, and keeping the arms and legs straight and stiff, and breathing the chest brimful, draw downward until the bar is about level with the waist. Let the weight run slowly back, repeat, and go on. - A Chest-widener
Dr. Sargent's ingenuity has provided a simple and excellent chest expander. He rigs two ordinary pulleys over blocks some feet above the head, and from five to six feet apart, and attaching weights at the floor ends of the ropes, puts ordinary handles on the other ends, and has the ropes just long enough so that when the weights are on the floor the handles are about a foot above the head. Now stand between and directly under them, erect, with the chest as full as you can make it, and keeping the elbows straight, and grasping the handles draw your hands slowly downward out at arm's-length, say about two feet. Next, let the weights drop gradually back, repeat, and so go on. This is excellent for enlarging the whole chest, but especially for widening it. A better present to a consumptive person than one of these appliances could hardly be devised. - A warped University Oarsman, imperfectly developed in Muscles not used in Rowing
With professional oarsmen, who for years have rowed far more than they have done anything else, and who have no especial care for their looks, or spur to develop harmoniously, the defects rowing leaves stand out most glaringly. The man in the figure is one of the most distinguished student-oarsmen America ever produced. - A warped Professional Sculler, imperfectly developed in Muscles not used in Rowing

All that people need for their daily in-door exercises is a few pieces of apparatus which are fortunately so simple and inexpensive as to be within the reach of most persons. Buy two pitchfork handles at the agricultural store. Cut off enough of one of them to leave the main piece a quarter of an inch shorter than the distance between the jambs of your bedroom door, and square the ends. On each of these jambs fasten two stout hard-wood cleats, so slotted that the squared ends of the bar shall fit in snugly enough not to turn. Let the two lower cleats be directly opposite each other, and about as high as your shoulder; the other two also opposite each other, and as high above the head as you can comfortably reach. - Lexington
