This book discusses the 19th-century growth of Manhattan northward. At the start of the 19th century, Manhattan was only a few blocks long; at the end of that century, the Upper East and Upper West Sides were being developed. Some of the interesting facts in this book include:
1. For the first few decades of the 19th century, the east side of downtown was the city's commercial hub because the "East River shoreline had always been better for sailing ships than the Hudson." As a result, the rich at first moved to the west side of downtown. But as trains and steam-powered ships became more prominent, the west side became more commercial, and the rich moved north.
2. River traffic also explains why New York overtook Philadelphia as the nation's dominant commercial city. The Delaware River froze more easily than the East River, and was further from the ocean and thus attracted less foreign trade.
3. Today, opponents of new housing claim that housing never filters down from the rich to the poor- but in the 19th century, filtering was common. For example, as middle-class WASP families fled the Lower East Side in midcentury, houses there sold for one-fourth the price they had fetched in the 1820s and 1830. Similarly, Lafayette Place "underwent slow decay, as the old row houses became boardinghouses, and tenements were built a block away on the other side of the Bowery."
4. Then as now, traffic was jammed and occasionally lethal to pedestrians- but horses rather than autos were the problem.
5. Then as now, economic conditions sometimes slowed building. During the Civil War, homebuilding collapsed even though the economy was sound, because of an increase in the price of building materials and a shortage of workmen. As a result, rents doubled. But because there were no zoning codes to limit building, construction began to recover after the war.
6. Today, many people think of New York's brownstones as classic. But the author notes that in the late 19th century, many people thought they were "monotonous and ugly. " For example, Edith Wharton described them as "hide-bound with deadly uniformity of mean ugliness."
