These fluorites are of a deep sea-green color; they occur both as perfect uncom¬ bined units and also in twin-crystal forms (twinning on the octahedral face). In the Santa (iertrudis mine, above Maguarichic. octahedral fluorite is present. These crys¬ tals vary in diameter from one-quarter to one-half inch, and rest upon a crystallized base of sphalerite, quartz and stephanite.

After easing up the fire, the lumps of partially reduced ore, mixed with cinders and slag, are shoveled on to the back of the fire; the slag is drawn out on to the workstone (any pieces of ore adhering to it are broken off and returned to the hearth), and it is then quenched in a water-box placed alongside the work- stone. One or two shovelfuls of coal, broken fairly small and generally kept damp, are throw'ii on the fire, together with the necessary amount of ore, which is also kept damp if in a fine state of division. It is part of the duty of the two smelters to ladle out the lead from the melting- pot into the molds. In smelting ore a fairly strong, steady blast is required, and it is made to blow right through so as to keep the front of the fire bright. A little lime is thrown on the front of the fire
