Down near the Potomac, on the Mall, to the westward of the Smithsonian turrets, is the extensive brick and brownstone building representing the dominant industry of the United States, which gives the politicians so much anxiety in catering for votes--the Agricultural Department. Here are spacious gardens and greenhouses, an arboretum and herbarium, the adjacent buildings also containing an agricultural museum. As over three-fifths of the men in the United States are farmers and farm-workers, and many others are in the adjunct industries, it has become a popular saying in Washington that if you wish to scare Congress you need only shake a cow's tail at it. This department has grown into an enormous distributing office for seeds and cuttings, crop reports and farming information. Among its curiosities is the "Sequoia Tree Tower," formed of a section of a Sequoia or Big Tree of California, which was three hundred feet high and twenty-six feet in diameter at the base. Behind the Agricultural Department, and rising almost at the river bank, and in front of the Executive Mansion, is the noted Washington Monument, its pointed apex elevated five hundred and fifty-five feet. This is a square and gradually tapering shaft, constructed of white Maryland marble, the walls fifteen feet thick at the base and eighteen inches at the top, the pyramidal apex being fifty-five feet high and capped with a piece of aluminum. Its construction was begun in 1848, abandoned in 1855, resumed in 1877 and finished in 1884, at a total cost of $1,300,000. The lower walls contain stones contributed by public corporations and organizations, many being sent by States and foreign nations, and bearing suitable inscriptions in memory of Washington. A fatiguing stairway of nine hundred steps leads to the top, and there is also a slow-moving elevator. From the little square windows, just below the apex, there is a grand view over the surrounding country. Afar off to the northwest is seen the long hazy wall of the Blue Ridge or Kittatinny Mountain range, its prominent peak, the Sugar Loaf, being fifty miles distant. To the eastward is the Capitol and its surmounting dome, over a mile away, while the city spreads all around the view below, like a toy town, its streets crossing as on a chess-board, and cut into gores and triangles by the broad, diagonal avenues lined with trees, the houses being interspersed with many foliage-covered spaces. Coming from the northwest the Potomac passes nearly at the foot of the monument, with Arlington Heights over on the distant Virginia shore, and the broad river channel flowing away to the southwest until lost among the winding forest-clad shores below Alexandria. From this elevated perch can be got an excellent idea of the peculiarities of the town, its vast plan and long intervals of space, so that there is quite plainly shown why the practical Yankee race calls it the "City of Magnificent
