It may be here remarked, with reference to the site selected for the Monument, that the foundations were laid but a short distance to the east of the meridian line, run, at the instance of President Jefferson, by Nicholas King, surveyor, October 15, 1804. The report of Mr. King, as found in the Department of State, bears the endorsement, "to be filed in the office of State as a record of demarcation of the first meridian of the United States." This line, by the President's instructions, passed through the center of the White House, and where it intersected a line due east and west through the center of the Capitol a small monument or pyramid of stones was placed—an object which disappeared about the year 1874, in the process of improving the Monument grounds. It would also appear that the center of the District of Columbia, within its original lines, was not far removed northwestward from the Monument as it stands, being near the corner of Seventeenth and C streets, N.W., 1,305 feet north and 1,579 feet west of the Monument. (National Geographic Magazine, vol. 6, p. 149.)
It does not appear, however, that these latter existing facts were in any manner considered by the Board of Managers in the selection of the site for the Monument.
The corner-stone for the Monument, a block of marble weighing "twenty-four thousand five hundred pounds," was quarried and presented to the Society by Mr. Thomas Symington, of Baltimore, Md. On its arrival in the city, the stone was enthusiastically drawn to the site of the Monument by many workmen from the navy yard, and other persons.
In planning the ceremonies to occur on the laying of the corner-stone of the Monument, the Society invited ex-President John Quincy Adams to deliver the oration, but the invitation, however, was regretfully declined by Mr. Adams on account of the state of his health.
Hon. Daniel Webster being requested to deliver the oration declined because of pressure of business and the shortness of the time allowed in which to prepare one.
Hon. Robert C. Winthrop, of Massachusetts, Speaker of the House of Representatives, being then requested consented to deliver the oration.
Invitations were sent by the committee of arrangements to Mrs. Alexander Hamilton, Mrs. Dolly P. Madison, Mrs. John Quincy Adams, Martin Van Buren, Millard Fillmore, Lewis Cass, General Sam Houston, Chief Justice Taney, George Washington Parke Custis, and other distinguished persons to attend the ceremonies of the laying of the corner-stone. The replies received indicate the interest of those invited in the erection of the Monument to Washington.
For the occasion transportation lines entering the District of Columbia reduced their usual rates of travel.
On the 4th of July, 1848, under a bright sky, in the presence of the President and Vice-President of the United States, Senators and Representatives in Congress, Heads of Executive Departments, and other officers of the Government, the Judiciary, Representatives of Foreign Governments, the corporate authorities of Washington, Georgetown, and Alexandria, military commands, associations of many descriptions, delegations from States and Territories and from several Indian tribes, and a great multitude of citizens, the corner-stone was laid.
The Rev. Mr. McJilton offered the consecration prayer, and the oration, lofty and eloquent, was delivered by the Hon. Robert C. Winthrop.
