- You don’t mean to say, Estelle, that you are tired of settlement work
“You don’t mean to say, Estelle, that you are tired of settlement work?” “But, Auntie, dear, poor people are so monotonous.” - 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. - Wolfe, Model A, 24 H.P

Waiting to bat - View of Bethlehem a Moravian settlement
VIEW of BETHLEHEM a Moravian settlement. I. Weld del. J. Dadley sculpt. Published Dec. 12 1798, by I. Stockdale, Picadilly. Bethlehem is the principal settlement, in North America, of the Moravians, or United Brethren. It is most agreeably situated on a rising ground, bounded on one side by the river Leheigh, which falls into the Delaware, and on the other by a creek, which has a very rapid current, and affords excellent seats for a great number of mills. The town is regularly laid out, and contains about eighty strong built stone dwelling houses and a large church. Three of the dwelling houses are very spacious buildings, and are appropriated respectively to the accommodation of the unmarried young men of the society, of the unmarried females, and of the widows. In these houses different manufactures are carried on, and the inmates of each are subject to a discipline approaching somewhat to that of a monastic institution. They eat together in a refectory; they sleep in dormitories; they attend morning and evening prayers in the chapel of the house; they work for a certain number of hours in the day; and they have stated intervals allotted to them for recreation. - View of Thomas Pope's Proposed Cantilever (1810)
The most notable invention of latter days in bridge construction is that of the cantilever bridge, which is a system devised to dispense with staging, or false works, where from the great depth, or the swift current, of the river, this would be difficult, or, as in the case of the Niagara River, impossible to make. The first design of which we have any record was that of a bridge planned by Thomas Pope, a ship carpenter of New York, who, in 1810, published a book giving his designs for an arched bridge of timber across the North River at Castle Point, of 2,400 feet span. Mr. Pope called this an arch, but his description clearly shows it to have been what we now call a cantilever. As was the fashion of the day, he indulged in a poetical description: "Like half a Rainbow rising on yon shore, While its twin partner spans the semi o'er, And makes a perfect whole that need not part Till time has furnish'd us a nobler art." - View of the Lesser Fall of Niagara

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 Wonders of nature

The water tank is seen frequently along the route of the railroads and plenty of water must be taken on and carried in the engine tender to make steam which is the power used to drive the big engines. - The Umpire
The Umpire - The tunnels
The tunnels are passages for trains under mountains, hills and rivers. The tunnels are dark but the trains are well lighted. Electric motors are often used, this avoids the smoke of steam engines which is very unpleasant in the tunnels. - The Train Ferry
The Train Ferry carries entire trains across rivers where there are no bridges. Some of the largest train boats have several tracks and carry a train on each. The boats are tied in slips at the shore so that the tracks meet exactly those on the land. - The Third Generation
- The Summer that the rain came not
The great drouths caused the price of corn to fluctuate but the aggregate corn yield kept on increasing with increased acreage and usually the year following a drouth was one of superabundance of corn. Such was the year of 1895 following the drouth of 1894. The proportion of cattle per thousand population steadily increased. Meanwhile our cattle markets became centralized and were always full to overflowing. Everybody wondered where the cattle came from. - The Stage coach
The Stage coach is used in the country where towns are few. The stages meet trains at the stations and take on passengers to be carried to their homes away from the railroad. Some of the stage routes are several hundred miles long. - The Round House
The Round House is the place where the railroad engines are kept when they are not working. The engines are turned around on a big turn table so each can be run on the different tracks which all lead to the turn-table in the centre. - The Residence of Abraham Lincoln
