The Department of the Treasury is the central agency through which the Federal Government conducts its financial affairs. Generally speaking, it receives and has custody of all funds paid to the Government and disburses all moneys of the Government. At the head of the department are the Secretary of the Treasury, the Under Secretary of the Treasury, and three Assistant Secretaries of the Treasury, whose offices are all located in the main building. The receipts of the Government come chiefly from internal-revenue collections and customs duties. The Bureau of Internal Revenue administers and enforces the internal-revenue laws and collects all internal-revenue taxes. The personnel of this bureau has been brought together and now occupies a beautiful new building recently completed as part of the development along the Mall. Import duties or customs are collected by the Bureau of Customs. Disbursements of Government funds can be made only on the authorization of Congress. When any payment is authorized, a warrant signed by the Secretary of the Treasury and countersigned by the Comptroller General of the United States is drawn. Upon this authority payment is made. The division of bookkeeping and warrants, under the general supervision of the commissioner of accounts and deposits, keeps complete records of all appropriation accounts as well as of public moneys covered into the Treasury and of warrants authorizing disbursements. The Treasurer of the United States is charged with responsibility for the actual receipt and disbursement of all public moneys that may be deposited in the United States Treasury and in all other depositaries authorized to receive deposits of Government funds for credit in the account of the Treasurer of the United States. He has also many other fiscal duties. The public-debt service handles the records and operations pertaining to the issue and retirement of the public debt and the interest payments thereon, under the supervision of the commissioner of the public debt. The Bureau of the Mint manufactures the coin circulating medium of the country. It maintains mints at Philadelphia, San Francisco, and Denver for the coinage of money, as well as assay offices in New York and elsewhere. The Bureau of Engraving and Printing at Washington engraves and prints notes, bonds, securities, stamps, checks, etc. The Comptroller of the Currency is charged under the law with the supervision of national banks.
