oom for farther use. Charged quicksilver is preferred to the pure metal, as with it amalgamation is found to proceed more rapidly. amalgamation of roasted ores. In some of the mining districts of Nevada, and particularly in the neighborhood of Austin, where the ores consist of various compound sulphides of silver, containing a considerable amount of antimony, the ordinary pan process, as practised at Virginia City, cannot be advantageously employed. The ores from this part of the State conseen stampers, with all the necessary furnaces, pans, and appliances, will treat eight tons of ore in the course of twenty-four hours, with a total consumption of about ten cords of wood. It is stated that the loss of silver in the neighborhood of Austin, where the ores contain little or no gold, seldom exceeds seven per cent of the assay value. Spencer's amalgamator. Amalgam retort.

The camel consists of twin hollow vessels, so arranged that they can be applied on either side of the ship's hull. They are made water-tight, and on the deck of each windlasses are attached, by which ropes passed under the keel of the vessel are worked. Each half of the camel is allowed to fill with water, which sinks with the weight, and when the ropes are adjusted the water is pumped out, and the buoyancy of the hollow vessels lifts the ship out of its bed at the bottom of the stream. Austin's plan for raising sunken vessels. The largest men-of-war were thus lifted over the shoals of the Zuyder-Zee. The camel has been used in many other places since. A modified form consists of caissons or large barrels submerged and attached by slings to the vessel. Captain Austin's plan differs from those described in having large inflatable canvas bags h h h h, rendered water and air proof by caoutchouc and strengthened by envelopes of netting.

drated gypsum, hydraulic cement, steatite, alum, and the neutralized and dried residuum of the so-called sodawater manufacture. Lillie used slabs of chilled cast-iron and flowed cast-iron over wrought-iron ribs. Herring made safes with boiler-iron exterior, hardened steel inner safe, and the interior filled with a casting of franklinite around rods of soft steel. Tann, 1843, used an outer and an inner metal casing filled in with a composition of equal quantities of alum and gypsum, or Austin's cement; within the inner casing was a wooden lining separated from the casing by a space filled with the same compound. Sherwood, 1850 to 1854, mentions a safe within a safe, with a filling of fire-brick, melted alum, and clay. Steam or water, or carbonic-acid gas, injected or evolved in the safe. Safe in a safe, intervening space filled with water; corners of angle-iron, and other points of construction. Safe burns loose (in case of fire) and falls into a protected place. An arrang
