The zinc-iron alloy is very brittle, and contains by analysis 6 per cent of iron, and is used to cast small art ornaments from. A hot galvanizing plant, having a bath capacity of 10 feet by 4 feet by 4-1/2 feet outside dimensions, and about 1 inch in thickness, will hold 28 tons of zinc.
Thus, the B.E.2c was first used in formations, but with a full load of bombs it could not carry an observer, and its moderate speed left it an easy prey to hostile fighters. Early in 1916 appeared the Martinsyde single-seater bomber with an endurance of 4-1/2 hours, and in 1917 the D.H.4 which was much used for day-bombing.
Calcination of the Ore. Having arranged a proper mixture of ores in the yard, it is weighed out in boxes to the calcining-men. This is drawn up an inclined plane over the tops of the furnaces, and from thence emptied through hoppers, 3-1/2 to 4-1/2 tons at a time, into the large calcining furnace.
Now-a-days, they are generally made either of canvas, or of a twilled sacking, and, when spread out, measure 4-1/2 feet by 3-1/2; but when lashed up, and ready for stowing away in the netting, they form long sacks, about as big as a man's body, but not tapering to the ends.

There has been a matinee performance at the theater from 4-1/2 to 5 comes a stream of homeward bound ladies. Then outside some belated passenger frantically running, jumping after the boat.
As a result the type determined upon was mounted on a pedestal fixed to the chassis of an automobile or to the deck of a ship in case it was to be used in naval warfare. The heaviest gun manufactured in Germany was of 4-1/4-inch calibre, throwing a shell of forty pounds weight. This could be mounted directly over the rear axle of a heavy motor truck.
The guide bars for guiding the top of the piston rod are of steel, 4 inches broad, fixed to rib iron bearers, with hard wood 1/4 of an inch thick, interposed. The connecting rod is 6 feet long between the centres, and is fitted with bushes of white metal. The eccentrics are formed of wrought iron, and have 4-1/8 inches of throw. The link of the link motion is formed of wrought iron.
Johnson, who had enjoyed a commanding lead of a set and 4-1, had slumped, and Pearson had pulled even at a set-all, and was leading at 5-1 and 40-15, point set match. He pulled Johnson far out to the forehand and came to the net. Johnson chopped viciously down the side-line, but Pearson volleyed to Johnson's deep backhand corner.
On its summit was an oval altar 6 feet long and 4-1/2 wide. It was composed of flat pieces of limestone, which had been burned red, some portions having been almost converted into lime. On and about this altar I found abundance of charcoal. At the sides of the altar were fragments of human bones, some of which had been charred.
