This air, or this wind, for it is a kind of trade wind which blows steadily down 600 miles of rich quartz croppings during an hour and a quarter every day, except Sundays, is heavily charged with exquisitely fine, impalpable gold...
Adsorbing Gel. One of the most efficient adsorbent materials known, silica gel was first produced commercially (for use in gas masks) in World War I. It also has industrial uses as a dehydrator and catalyst. Made by drying a gelatinous form of silicon dioxide, silica gel looks like crushed quartz, is riddled with invisible pores so numerous that a cubic inch has more than 50,000 square feet of interior surface. By adsorption (sticking of moisture to the surface), silica gel can hold half its own weight in water without swelling, caking or developing a visible sweat...
