distributed into the aggregate, South-sea, and general funds, the creditors of the public, like those of private persons, were induced to accept of five per cent. for the interest of their money, which occasioned a saving of one per cent. upon the capital of the greater part or the debts which had been thus funded for perpetuity, or of one-sixth of the greater part of the annuities which were paid out of the three great funds above mentioned. This saving left a considerable surplus in the produce of the different taxes which had been accumulated into those funds, over and above what was necessary for paying the annuities which were now charged upon them, and laid the foundation of what has since been called the sinking fund. In 1717, it amounted to £523,454:7:7½. In 1727, the interest of the greater part of the public debts was still further reduced to four per cent.; and, in 1753 and 1757, to three and a-half, and three per cent., which reductions still further augmented the sinking fund.
A sinking fund, though instituted for the payment of old, facilitates very much the contracting of new debts. It is a subsidiary fund, always at hand, to be mortgaged in aid of any other doubtful fund, upon which money is proposed to be raised in any exigency of the state. Whether the sinking fund of Great Britain has been more frequently applied to the one or to the other of those two purposes, will sufficiently appear by and by.
Besides those two methods of borrowing, by anticipations and by a perpetual funding, there are two other methods, which hold a sort of middle place between them; these are, that of borrowing upon annuities for terms of years, and that of borrowing upon annuities for lives.
During the reigns of king William and queen Anne, large sums were frequently borrowed upon annuities for terms of years, which were sometimes longer and sometimes shorter. In 1695, an act was passed for borrowing one million upon an annuity of fourteen per cent., or
