With this view, it is recommended that as soon as the war shall be over all the surplus in the Treasury not needed for other indispensable objects shall constitute a sinking fund and be applied to the purchase of the funded debt, and that authority be conferred by laws for that purpose. The act of the 6th of August, 1846, "to establish a warehousing system," has been in operation more than a year, and has proved to be an important auxiliary to the tariff act of 1846 in augmenting the revenue and extending the commerce of the country. Whilst it has tended to enlarge commerce, it has been beneficial to our manufactures by diminishing forced sales at auction of foreign goods at low prices to raise the duties to be advanced on them, and by checking fluctuations in the market. The system, although sanctioned by the experience of other countries, was entirely new in the United States, and is susceptible of improvement in some of its provisions. The Secretary of the Treasury, upon whom was devolved large discretionary powers in carrying this measure into effect, has collected and is now collating the practical results of the system in other countries where it has long been established, and will report at an early period of your session such further regulations suggested by the investigation as may render it still more effective and beneficial. By the act to "provide for the better organization of the Treasury and for the collection, safe-keeping, and disbursement of the public revenue" all banks were discontinued as fiscal agents of the Government, and the paper currency issued by them was no longer permitted to be received in payment of public dues. The constitutional treasury created by this act went into operation on the 1st of January last. Under the system established by it the public moneys have been collected, safely kept, and disbursed by the direct agency of officers of the Government in gold and silver, and transfers of large amounts have been made from points of collection to points of disbursement without loss to the Treasury or injury or inconvenience to the trade of the country.
