- Bessemer Converting Vessel
a, a, a, tuyères; b, air-space; c, melted metal A very important development of the manufacture of steel followed the introduction of the 'Bessemer process,' by means of which a low carbon or mild cast-steel can be produced at about one-tenth of the cost of crucible steel. It is used for rails, for the tires of the wheels of railway carriages, for ship-plates, boiler-plates, for shafting, and a multitude of constructional and other purposes to which only wrought iron was formerly applied, besides many for which no metal at all was used. - The Rocket 1830
In 1830 all this had disappeared, and we find in Mr. Nasmyth's sketch a regular fire-box, such as is used to this moment. In one word, the Rocket of 1829 is different from the Rocket of 1830 in almost every conceivable respect; and we are driven perforce to the conclusion that the Rocket of 1829 never worked at all on the Liverpool and Manchester Railway; the engine of 1830 was an entirely new engine. - Plan of Harpers Ferry Bridge
Shortly after the Harpers Ferry bridge reconstruction, Bollman was made foreman of bridges. It is apparent that, on the basis of his practical ability, enhanced by the theoretical knowledge gained by intense self-study, he eventually came to assist Chief Engineer Benjamin H. Latrobe in bridge design. He later took this work over entirely as Latrobe’s attentions and talents were demanded in the location and extension of the line between Cumberland and Wheeling. - Wendell Bollmans Patent Bridge
Patent Iron Suspension Railroad Bridge. The undersigned would inform the officers of Railroads and others, that he is prepared to furnish Drawings and Estimates for Bridges, Roofs, etc., on the plan of Bollman’s Patent. The performance of these bridges, some of which have been in use for six years, has given entire satisfaction. Their simplicity of construction renders repairs easy and cheap, and by a peculiar connection of the Main and Panel Rods at the bottom of the Posts, all danger from the effects of expansion, which has heretofore been the chief objection to Iron Bridges, is entirely removed.

In some English and Scotch mines, and also in some of the French mines, where the seams of coal are thin, boys, who are called “putters,” are employed to draw small carts along a railway. They fasten themselves to the cart with belts around their waists, and draw it along, going sometimes on their hands and feet where the road is wet and rough. Sometimes one of them pulls the cart while the other pushes it. In some of the Scotch mines girls formerly performed this work; but of late the laws do not allow women to work under ground. Girls used to carry on their backs a basket fastened to a leather strap which passed around their foreheads. A lamp was attached to the strap, and in this way they carried their loads up the long ladders and through the inclines, sometimes a distance of several hundred feet. If a strap broke, a block of coal fell, or a bearer missed her footing, those below were seriously hurt, and many fatal accidents occurred. This primitive mode of raising coal was abolished by law. The owners of the mines had become so careless in regard to the management of their laborers that the government was obliged to interfere. - A Steam Street Railway Motor
While in Paris, President Yerkes, of the North Chicago Street Railway Company, purchased a noiseless steam motor, the results in experimenting with which will be watched with great interest. The accompanying engraving, for which we are indebted to the Street Railway Review, gives a very accurate idea of the general external appearance. The car is all steel throughout, except windows, doors, and ceiling. It is 12 ft. long, 8 ft. wide, and 9 ft. high, and weighs about seven tons. The engines, which have 25 horsepower and are of the double cylinder pattern, are below the floor and connected directly to the wheels. The wheels are four in number and 31 in. in diameter. The internal appearance and general arrangement of machinery, etc., is about that of the ordinary steam dummy. It will run in either direction, and the exhaust steam is run through a series of mufflers which suppress the sound, condense the steam and return the water to the boiler, which occupies the center of the car. The motor was built in Ghent, Belgium, and cost about $5,000, custom house duties amounting to about $2,000 more. - The first Railway Journey in England
It was called the 'Locomotion.' George Stephenson stood ready to drive it as soon as the trucks, which a stationary engine was lowering down the slope by means of a wire rope, had been attached to it. In the first of these trucks came the Directors of the Railway Company and their friends, followed by twenty-one trucks (all open to the sky, like ordinary goods-trucks), loaded with various passengers, and finally six more waggons of coal. Such was the first train. A man on horseback, carrying a flag, having taken up his position in front of the 'Locomotion' to head the procession, the starting word was given, and with a hiss of steam, half drowned in the shouting of the crowd, the first railway journey ever made in England was begun. - The Forth Bridge
The Forth Bridge at the Present Day. Building the Bridge. Train crossing the Bridge. The mouth of the Forth has very nearly bitten Scotland in two, and anybody who wishes to travel from Edinburgh to Dunfermline would have to go a long way round if they objected to crossing the river. Formerly a great many people did object to this, because they knew that, although the voyage was only about a short mile, the great billows from the North Sea would meet them before it was over, and give them a very unpleasant time. So everybody who had anything to do with the Forth was willing that it should be spanned by a reliable bridge, and plans for carrying this into effect were frequently proposed. Indeed, arrangements were almost completed in 1879 for building a huge suspension bridge from shore to shore. The drawings were made, the estimates prepared, and the spades and trowels even beginning to work on the foundations, when, one sad December night, a terrible gale arose. All through the hours of darkness it roared and shrieked across the British Isles, working havoc upon sea and land, but, when morning came at last, few were prepared for the appalling catastrophe it had caused. Sweeping up the Firth of Tay, it had torn away a portion of the great railway bridge that crossed the inlet, and hurled it into the water. A train was passing over at the time, and plunged into the abyss with all its passengers. The terrible event shook public confidence, and we might almost say that the gale of that December night caught all the drawings and papers connected with the proposed suspension bridge over the Forth, and swept them from public favour. Immediately afterwards, Sir John Fowler and Mr. Benjamin Baker (both celebrated engineers) came forward with an alternative plan of which no one could doubt the strength. It may perhaps be described as an arch-suspension bridge, because the design includes the strength of both styles; but engineers themselves call it a cantilever bridge.
