more than three thousand pounds--is not a prize attainable in river washing. That lump, its owner says, he got out of a vein, which vein he comes to Europe to seek aid in working. Veins of quartz containing gold, when they occur, directly they cease to be superficial, cease generally to be very profitable to their owners. But of that we shall have to say more presently. By this time we have had occasion to observe more than once that gold and quartz are very friendly neighbors. Now, we will make use of the fact which we have been saving up so long, that when granite decomposes, quartz, the heaviest material is least easily carried away, and when carried away is first to be deposited by currents. Gold also, is very heavy; in its lightest compound, it is twelve times heavier than water, and pure gold is nineteen times heavier; gold, therefore, when stirred out of its place by water, will soon settle to the bottom. Very often gold will not be moved at all, nor even quartz; so gold and quartz remain, while substances which formerly existed in their neighborhood are washed away. Or when the whole is swept away together, after the gold has begun sinking, quartz will soon be sinking too; and so, even in shingle or alluvial deposits, gold and quartz are apt to occur as exceedingly close neighbors to each other. How the gold forms in those old rocks, we have no right to say. Be it remembered, that in newer formations it occurs, although more sparingly. How the gold forms, we do not know. In fact, we have no right to say of gold that it is formed at all. In the present state of chemistry, gold is considered as an element, a simple substance, of which other things are formed, not being itself compounded out of others. In the present state of our knowledge, therefore--and the metals _may_ really be elements--we have nothing to trouble ourselves about. Gold being one of the elements (there are somewhere about forty in all) of which the earth is built, of course existed from the beginning, and will be found in the oldest rocks. It exists, like other elements, in combination. It is combined with iron, antimony, manganese, copper, arsenic, and other things. But it is one great peculiarity of gold that it is not easily oxydized or rusted; rust being caused in metals by the action of oxygen contained in our air. When, therefore, gold, in a compound state, comes to be superficial, the air acting on the mass will generally oxydize the other metals, and so act upon them, more especially where water helps, that in the lapse of time this superficial gold will have been purified in the laboratory of nature, and may be finally picked up in the pure, or nearly pure, state; or else it may be washed, equally pure, from the superficial earth, as is now done in the majority of gold districts. But deep below the surface, in quartz veins contained within the bowels of a mountain--though, to be sure, it is not often found in such
