Every morning the village cowherd, who was a most important personage, would walk the streets of New Amsterdam and sound his horn at each burgher's door. The cows were immediately turned out to him, and when he had collected his herd he would drive them by the pretty valley road to the commons, and there by his vigilance prevent them from straying into the unsettled part beyond. At a later period the mighty Dutch warriors whose prowess the immortal Deiderich Knickerbocker has celebrated, made the commons their training ground, and here was also marshalled the force which wrested the city from the Dutch. Under the English it became a place of popular resort, and was used for public celebrations, the town having reached the lower limit of the commons. Here were celebrated his Majesty's birth-day, the anniversary of the Gunpowder Plot, and other loyal holidays, and here were held the tumultuous assemblies, the meetings of the Liberty Boys, and other demonstrations which preceded the Revolution. In 1736 the first building, a Poor-House, was erected on the site of the present City Hall. In 1747 a powder-house was erected by the city within the limit of the commons, near the site of the present City Hall. The gallows stood on the site of the new Post-office, and in 1756 was removed to the vicinity of the present Five Points. In 1757 the new jail, more recently known as the Hall of Records, was erected. In the same year, the old French war being in progress, wooden barracks were erected along the Chambers street front of the Park. In 1757 a part of the site of the City Hall was laid out as a burying ground for the inmates of the Alms-House. In 1764 a whipping-post, stocks, cage, and pillory were erected in front of the new jail. In 1755 a Bridewell was built on that portion lying between the City Hall and Broadway. After the Revolution, in 1785, the Park was first enclosed in its present form, by a post-and-rail fence, and a few years later this was replaced by wooden palings, and Broadway along the Park began to be noted as a fashionable place of residence. In 1816, the wooden fence gave way to an iron railing, which was set with due ceremonies by the city authorities. In 1795 a new Alms-House was built along the Chambers street front, but in 1812, Bellevue Hospital having been finished, the paupers were transferred thither, and the old building was refitted as a Museum. In 1802 the corner-stone of the present City Hall was laid. The building was finished in 1810. Some years later the old buildings were removed or converted into offices for the city and county officials. In 1870, the southern portion having been ceded to the Federal Government for the erection of a new Post-office thereon, the Park was laid out on a new plan, and handsomely adorned with walks, shrubbery, fountains, etc. It is now an ornament to the city.
