The iron piers are each formed of four columns, and the columns consist of two Barlow rails, with a slotted iron plate ½ inch thick let in between the rails, and the whole being riveted together connects each pair of side columns. The details show the system of cross and diagonal bracing. The columns are each supported by four buttresses formed of plates and angle-irons.
Now the gilt spike that crowned her pillar was made fast with angle-irons let into the marble and the edge of one of these irons projected somewhat and was rough. Looking at it the thought came into Miriam's mind that it might serve to rub through the cord with which her hands were bound.
Through all these phenomena and more though I ran with wild horses over illimitable plains of rustling grass; though I crouched belly-flat under appalling fires of musketry; though I was Livingstone, painless, and incurious in the grip of his lion my shut eyes saw the lamp swinging in its gimbals, the irregularly gliding patch of light on the steel ladder, and every elastic shadow in the corners of the frail angle-irons; while my body strove to accommodate itself to the infernal vibration of the machine.
There are various practicable plans of fastening bolts to the backs of plates, and of holding plates between angle-irons, to avoid boring them through. It is believed that plates will ultimately be welded. Boiler-joints have been welded rapidly and uniformly by means of light furnaces moving along the joint, blowing a jet of flame upon it, and closely followed by hammers to close it up.
When the tower was finally completed, he ran the lines up inside the angle-irons to protect them from the terrific winds, so that the tower man could instantly communicate with the forester at Oakdale. Now the cabin went up. Large, flat stones were assembled and a rough but stable foundation made below the level of the ground.
There were oil-cars, and hay-cars, and stock-cars full of lowing beasts, and ore-cars, and potato-cars with stovepipe-ends sticking out in the middle; cold-storage and refrigerator cars dripping ice water on the tracks; ventilated fruit and milk-cars; flatcars with truck-wagons full of market-stuff; flat-cars loaded with reapers and binders, all red and green and gilt under the sizzling electric lights; flat-cars piled high with strong-scented hides, pleasant hemlock-plank, or bundles of shingles; flat-cars creaking to the weight of thirty-ton castings, angle-irons, and rivet-boxes for some new bridge; and hundreds and hundreds and hundreds of box-cars loaded, locked, and chalked.
The spandrels are formed of uprights and diagonals, the former being made of four angle-irons, and the latter of one angle-iron. On the top of the longitudinal girders are fixed cross pieces of single Barlow rails, upon which again are fastened two longitudinals of wood 12 in. square in section, and which in their turn carry the rails of the permanent way.
