In all countries where there is tolerable security, every man of common understanding will endeavour to employ whatever stock he can command, in procuring either present enjoyment or future profit. If it is employed in procuring present enjoyment, it is a stock reserved for immediate consumption. If it is employed in procuring future profit, it must procure this profit either by staying with him, or by going from him. In the one case it is a fixed, in the other it is a circulating capital. A man must be perfectly crazy who, where there is tolerable security, does not employ all the stock which he commands, whether it be his own or borrowed of other people, in some one or other of those three ways.
In those unfortunate countries, indeed, where men are continually afraid of the violence of their superiors, they frequently bury and conceal a great part of their stock, in order to have it always at hand to carry with them to some place of safety, in case of their being threatened with any of those disasters to which they consider themselves as at all times exposed. This is said to be a common practice in Turkey, in Indostan, and, I believe, in most other governments of Asia. It seems to have been a common practice among our ancestors during the violence of the feudal government. Treasure-trove was in those times considered as no contemptible part of the revenue of the greatest sovereigns in Europe. It consisted in such treasure as was found concealed in the earth, and to which no particular person could prove any right. This was regarded in those times as so important an object, that it was always considered as belonging to the sovereign, and neither to the finder nor to the proprietor of the land, unless the right to it had been conveyed to the latter by an express clause in his charter. It was put upon the same footing with gold and silver mines, which, without a special clause in the charter, were never supposed to be comprehended in the general grant of the lands, though mines of lead, copper, tin, and coal were, as things of smaller consequence.
