very much the consumption of Great Britain, and of which a part, therefore, must be exported to other countries. But this cannot be done without forcing some part of the capital of Great Britain into a roundabout foreign trade of consumption. Maryland and Virginia, for example, send annually to Great Britain upwards of ninety-six thousand hogsheads of tobacco, and the consumption of Great Britain is said not to exceed fourteen thousand. Upwards of eighty-two thousand hogsheads, therefore, must be exported to other countries, to France, to Holland, and to the countries which lie round the Baltic and Mediterranean seas. But, that part of the capital of Great Britain which brings those eighty-two thousand hogsheads to Great Britain, which re-exports them from thence to those other countries, and which brings back from those other countries to Great Britain either goods or money in return, is employed in a roundabout foreign trade of consumption; and is necessarily forced into this employment in order to dispose of this great surplus. If we would compute in how many years the whole of this capital is likely to come back to Great Britain, we must add to the distance of the American returns that of the returns from those other countries. If, in the direct foreign trade of consumption which we carry on with America, the whole capital employed frequently does not come back in less than three or four years; the whole capital employed in this roundabout one is not likely to come back in less than four or five. If the one can keep in constant employment but a third or a fourth part of the domestic industry which could be maintained by a capital returned once in the year, the other can keep in constant employment but a fourth or a fifth part of that industry. At some of the outports a credit is commonly given to those foreign correspondents to whom they export their tobacco. At the port of London, indeed, it is commonly sold for ready money. The rule is, Weigh and pay . At the port of London, therefore, the final returns of the whole roundabout trade are more distant than the returns from America by the time only which the goods may lie unsold in the warehouse; where, however, they may sometimes lie long
