Sections of an English Coal Mine
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.

Erection of a Cantilever
The new bridge at Poughkeepsie has three of these cantilevers, connected by two fixed spans, as shown in the illustration. The fixed spans have horizontal lower chords, and really extend beyond each pier and up the inclined portions, to where the bottom chord of the cantilever is horizontal. At these points the junctions between the spans are made, and arranged in such a way, by means of movable links, that expansion and contraction due to changes of temperature can take place. The fixed spans are 525 feet long. Their upper chord, where the tracks are placed, is 212 feet above water. These spans required stagings to build them upon. These stagings were 220 feet above water, and rested on piles, driven through 60 feet of water and 60 feet of mud, making the whole height of the temporary staging 332 feet, or within 30 feet of the height of Trinity Church steeple, in New York. The[35] time occupied in building one of these stagings and then erecting the steel-work upon it was about four months. The cantilever spans were erected without any stagings at all below, and entirely from the two overhead travelling scaffolds, shown in the engraving. These scaffolds were moved out daily from the place of beginning over the piers, until they met in the centre. The workmen hoisted up the different pieces of steel from a barge in the river below and put them into place, using suspended planks to walk upon. The time saved by this method was so great that one of these spans of 548 feet long was erected in less than four weeks, or one-seventh of the time which would have been required if stagings had been used.
