Today one of the most remarkable features of New York is the Grand Central Terminal. The exterior finish is granite and Indiana lime-stone; the style somewhat Doric, modified by the French Renaissance. Over the entrance to the main building is a great arch surmounted by a statuary group wherein Mercury, symbolizing the glory of commerce, is supported by Minerva and Hercules who represent mental and moral force. Within, the main concourse of the station proper is an immense room with a floor space of 37,625 sq. ft. where the New York City Hall might be set and yet leave room to spare. It is covered with a vaulted ceiling 125 ft. high, painted a soft cloudy blue and starred over with the constellations of heaven. Great dome-shaped windows, three each at the east and west ends, furnish light. [Illustration: The Main Concourse, Grand Central Terminal] The entire site of the Grand Central Terminal comprises 30 blocks and 80 acres which above the surface are covered with a great variety of buildings, making almost a city in itself. Moreover, there is direct subway entrance to three large hotels, capable of housing as many as 10,000 persons, and to all these conveniences is added that of comfortable temperature throughout the terminal, no matter how cold the weather. [Illustration: Map of New York City, 1775 This survey, made in the winter of 1775, shows the city proper as it existed during the Revolutionary War. Places indicated by the lettering are described under the original as follows: A, Fort George. B, Batteries [at the two points of the island]. C, Military Hospital [south of Pearl St.]. D, Secretary's Office [near Fort George]. E, [Not Shown]. F, Soldiers' Barracks [at extreme right]. G, Ship Yards [lower right hand corner]. H, City Hall [Broad and Wall streets, site of present Sub-Treasury building]. I, Exchange. J, K, Jail and Workhouse [both situated on the "intended square or common," now City Hall Square]. L, College [Church and Murray streets; this was King's College, now Columbia University]. M, Trinity Church [the present Trinity was built on 1839-46, though it stands on the site of the old church built in 1696]. N, St. George's Chapel. O, St. Paul's Chapel [built in 1756, the oldest edifice still standing in N.Y.C.]. P to Z, various churches.] As distinctively "New York" as the sky-scrapers, are the hotels and apartment houses. Of the latter, there are more than in any other city in the world, and the number of persons who are giving up their houses and adopting this manner of life is steadily increasing. The first thing, in fact, that impresses a visitor on his arrival is the seemingly endless amount of buildings adopted for transients. A few of the largest hotels have space for several thousand persons at one time. [Illustration: New Amsterdam (Now New York City) in 1671
