The arrangements for laying the corner-stone were completed, and the 13th of April, 1808, fixed for that interesting ceremony. The order of exercises was as follows: At eleven o'clock the procession formed at the ferry, foot of Main Street, marched through that street to Sands Street, thence to Bridge Street, along Bridge to York Street, through York Street to Jackson, and thence to the ground. As Major Aycrigg had ever manifested unabated interest in this labor of love, he was properly selected as grand marshal of the day. The first division of the procession consisted of a company of United States marines, under command of Lieutenant-Commandant Johnson. The second division was composed of citizens of New York and Brooklyn. The third division embraced the committees of the various civic societies. The fourth division contained the Grand Sachem of the Tammany Society, Father of the Council, and orator of the day. The fifth division carried the corner-stone with the following inscription:-- IN THE NAME OF THE SPIRITS OF THE DEPARTED FREE. Sacred to the memory of that portion of AMERICAN FREEMEN, SOLDIERS AND CITIZENS, who perished on board the PRISON SHIPS OF THE BRITISH at the Wallabout during the REVOLUTION. This corner-stone of the vault erected by the TAMMANY SOCIETY OR COLUMBIAN ORDER Nassau Island, Season of Blossoms, year of the discovery the 316th, of the institution the 19th, and of the American Independence the 22d.

The sixth division was composed of a detachment of artillery under command of Lieutenant Townsend. The procession having reached the ground, the artillery were stationed upon a neighboring hill, and the various divisions took the positions assigned them. The oration, which was a brilliant effort, was delivered by Joseph D. Foy. The stone was then lowered to its place and duly laid by Benjamin Romaine, Grand Sachem of the Tammany Society, assisted by the committee, after which a grand salute was fired, and the band discoursed sweet and solemn notes. The vault was completed in May, 1808. Arrangements were made for an imposing display, and no pains were spared in preparation. The various societies and public bodies were ready and anxious to do all in their power to render the occasion impressive and memorable. The citizens turned out _en masse_ on the 26th of May, 1808, to bear testimony to the worth of these brave men whose obsequies were to be celebrated. They assembled at ten o'clock in the park in front of the City Hall, New York, under command of Brigadier Generals Morton and Steddiford, Garret Sickels, Grand Marshal, assisted by twelve aides.
