An interested group of men met for breakfast at the home of Colonel Thomas Handasyd Perkins, including William Tudor, Daniel Webster, Professor George Ticknor, Doctor John C. Warren, William Sullivan, and George Blake. On May 10, 1823, the first public meeting was called. Each member subscribed five dollars, and on June 7, 1823, the Bunker Hill Monument Association was established and the work of raising money was begun. Famed nineteenth-century philanthropist Amos Lawrence contributed $10,000 to the monument's erection. In the spring of 1825 the directors had purchased about 15 acres (61,000 m2) on the slope of Breed's Hill, but had not yet chosen a design. The first design committee consisted of Webster, noted engineer Loammi Baldwin, Jr., George Ticknor, Gilbert Stuart, and Washington Allston. One hundred dollars was offered for the best design; about 50 plans were presented in response. Choice was soon narrowed to a column and an obelisk and a new committee was appointed to procure designs and estimate expenses for each. At the next meeting the majority voted that the obelisk designed by Solomon Willard be used. The directors laid the cornerstone on June 17, 1825. The Marquis de Lafayette (who was on a 14-month tour of the United States on the 50th anniversary of the War) performed the ceremony, Webster delivered the oration, and the Grand Master of the Grand Lodge of Massachusetts, Ancient Free and Accepted Masons, conducted the services. Rev. Joseph Thaxter, who was wounded in the battle, officiated as chaplain at the ceremony, offering a prayer in thanks for the colonists' victory. More than 100,000 attended the event, including 190 veterans who had participated in the battle. Blocks of granite for the monument averaged two cubic yards each and were quarried by wedging. Delivered to the site of the monument at an actual cost of $5.40 per cubic yard from a quarry opened for the purpose far under the average contract offers for the same of $24.30. Work proceeded somewhat slowly at first, but the Granite Railway was completed in short order and became operational on October 7, 1826, as the first commercial railroad in the United States functioning as a common carrier. Construction was frequently halted as available funds were depleted. To bring the project to completion the Monument Association in 1838 began to sell off the of the battlefield as house lots, eventually preserving only the summit of Breed's Hill
