This simple, stately building is a fitting home for the head of a great republic. In the main building are the living apartments of the president and his family, and the great rooms used for state receptions; the largest and handsomest of these is the famous East Room. Other rooms used on public occasions are known, from the color of the furnishings and hangings, as the Blue Room, the Green Room, and the Red Room. There is also the great State Dining Room, where the president entertains at dinner the important government officials and foreign representatives. In the Annex, adjoining the White House on the west, are the offices of the president and those who assist him in his work. In this part of the building is the cabinet room, where the president meets the heads of the various departments to consult with them concerning questions of national importance. Across the street from the president's office is the immense granite building occupied by the three departments of State, War, and Navy. The secretaries in charge of these departments have their offices here, together with a small army of clerks. [Illustration: THE UNITED STATES TREASURY] On the opposite side of the White House from the State, War, and Navy Building is the National Treasury. The Treasury Building is one of the finest in the city. To see the splendid colonnade on the east is alone worth a journey to Washington. From this building all the money affairs of the United States government are directed. In the Treasury Building and in the Bureau of Engraving and Printing one may see the entire process of manufacturing and issuing paper money. In the Treasury we see new bills exchanged for old, worn-out bills, which are ground to pieces to destroy forever their value as money. [Illustration: BUREAU OF ENGRAVING AND PRINTING, "UNCLE SAM'S MONEY FACTORY"] But to understand the story of a dollar bill or a bill of any other value we must visit the Bureau of Engraving and Printing. This building, which is some distance from the Treasury Building, reminds us of a large printing office, and that is just what it is. Here we are shown from room to room where many men and women are at work, some engraving the plates from which bills are to be printed and others printing the bills. The paper used is manufactured by a secret process for United States money, and every sheet is most carefully counted at every stage of the printing. Altogether the sheets are counted fifty-two times. Many clerks are employed to keep a careful account of these sheets, and it is almost impossible for a single bill or a single piece of paper to be lost or stolen. After the money is printed it is put into bundles, sealed, and sent in a closely guarded steel wagon to the Treasury Building, where it is stored in great vaults until it is issued.
