West Street which runs north along the water front is the great shipping section. It is one long succession of piers, docks, steamers, ships and ferries. One sees ships from all over the world at the docks loading and unloading freight. Streets are full of huge trucks, moving vans and vehicles of all sorts, many of them drawn by horses. One still sees many horses in New York City, a few on little old fashioned carriages and coaches but a great many on trucks, milk wagons, and carts. Most of them seem pretty well cared for, although in the winter one feels very sorry for them because of the slippery pavements. Much of New York City is paved with paving stones, which are very hard, uneven and difficult for horses to walk on. In parts of the city there are steep hillsides and when these are covered with ice and snow it is extremely difficult for horses to keep their feet. The section along West Street from about Chambers to Desbrosses is known as "The Farm". In this district are the receiving stations for the huge food supplies brought in from the South and from the farming districs adjacent to New York City. New York City has three large municipal markets: Washington, Brooklyn and Harlem.
