At Block Island the tide rises only two feet. At Hallet's Point, near the city, it rises more than seven feet. The quiet peaceful tide at Block Island becomes here a swiftly flowing stream that surges with foam and fury between the rough rocky banks, and making many a dangerous eddy and whirl-pool. It is no wonder the sailors used to call this place Hell Gate.
Let us look at this place a moment. The East River is open to the sea at each end. It is not like a real river, flowing down hill, and with a current constantly flowing in one direction.

It seems as if the whole of the great sea was forever slowly rising or falling, up and down, with a slow and solemn motion.
Any boy who lives by the shore knows that this is the tide. He knows that all his fun depends on this regular rising and falling of the tide. At high tide the fishing is good. At low tide the flats are bare, and the boys can dig clams or watch the long-legged plovers wading about in the shallow water. This curious rising and falling of the tide is caused by the attraction of the moon. The sun also helps, but in a lesser degree.

Were it not for the moon, Sandy Hook would creep [Pg 772] slowly out over the shallow waters until it nearly reached Coney Island. The friendly tide comes sweeping in from the sea, and spreads far and wide over the bay. It fills miles and miles of bays and rivers with water, and then when the moon passes on, and the water can follow her no farther, it turns in a mighty flood, and scours and sweeps out all the channels. The outflowing tide is a big broom to brush away the sand and mud, and keep the front door of our port open to all the ships of the world.
