for of all things which the soil within this realm produces or yields, gold and silver are the most excellent, and of all persons in the realm, the King is, in the eye of the law, most excellent.  And the common law, which is founded upon reason, appropriates everything to the person whom it best suits, as common and trivial things to the common people, things of more worth to persons in a higher and superior class, and things most excellent to those persons who excel all others; and because gold and silver are the most excellent things which the soil contains, the law has appointed them (as in reason it ought) to the person who is most excellent, and that is the King.—­The second reason was, in respect of the necessity of the thing.  For the King is the head of the Weal-public and the subjects are his members; and the office of the King, to which the law has appointed him, is to preserve his subjects; and their preservation consisted in two things, viz., in an army to defend them against hostilities, and in good laws.  And an army cannot be had and maintained without treasure, for which reason some authors, in their books, call treasure the sinews of war; and, therefore, inasmuch as God has created mines within this realm, as a natural provision of treasure for the defence of the realm, it is reasonable that he who has the government and care of the people, whom he cannot defend without treasure, should have the treasure wherewith to defend them.—­The third reason was, in respect of its convenience to the subjects in the way of mutual commerce and traffic.  For the subjects of the realm must, of necessity, have intercourse or dealing with one another, for no individual is furnished with all necessary commodities, but one has need of the things which another has, and they cannot sell or buy together without coin.—­And if the subject should have it (the ore of gold or silver) the law would not permit him to coin it, nor put a print or value upon it, for it belongs to the King only to fix the value of coin, and to ascertain the price of the quantity, and to put the print upon it, which being done, the coin becomes current for so much as the King has limited.—­So that the body of the realm would receive no benefit or advantage if the subject should have the gold and silver found in mines in his land; but on the other hand, by appropriating it to the King, it tends to the universal benefit of all the subjects in making their King able to defend them with an army against all hostilities, and when he has put the print and value upon it, and has dispersed it among his subjects, they are thereby enabled to carry on mutual commerce with one another, and to buy and sell as they have occasion, and to traffic at their pleasure.  Therefore, for these reasons, viz., for the excellency of the thing, and for the necessity of it, and the convenience that will accrue to the subjects, the common law, which is no other than pure and tried reason, has appropriated the ore of gold and silver to the King, in whatever land it be found.”
