The story of New Haven

The man who planted the Elm City

New Haven got its nickname from one man's shovel. Between 1787 and 1796 James Hillhouse brought young elms from his farm out toward Meriden and planted them in rows along the town's streets and around the Green. A 1911 history says he set out many with his own hands, helped by a boy who held the trees or drove the stakes while Hillhouse shoveled in the dirt. That boy was Jeremiah Day, who grew up to be president of Yale. In 1792 Hillhouse also laid out Hillhouse Avenue, 105 feet wide, through the family farm, and its arching elms became famous. Most of those trees are long gone, but the name stuck.561

The judges on West Rock

In 1661 two of the judges who had signed King Charles I's death warrant, Edward Whalley and William Goffe, fled to New Haven. John Davenport helped hide them, and on May 15 they first lodged in a cluster of huge stone pillars near the top of West Rock, a spot where they could watch the harbor. Richard Sperry, who farmed on the far side of the ridge, sent food up with his boys, tied in a cloth and left on a certain stump. One night a panther put its head into the opening and glared at them, and one judge ran all the way down to Sperry's house. They left the cave soon after. Someone later carved on the rock: Opposition to Tyrants is Obedience to God.781

Oysters and the Long Wharf

New Haven has always lived off its harbor. In 1772 the Assembly let the owners of Long Wharf run a lottery to pay for it, and in 1779 British raiders burned the shipping tied up there. When the steamboat United States began regular runs to New York in 1824, the crew fired a cannon from the bow coming into port so the stagecoaches for Hartford and Boston would be ready, and the ticket system later used on steamboats everywhere was first tried on board. Out in Fair Haven, oystermen sailed as far as the Chesapeake by about 1823. In 1834 the schooner Mary and Martha laid down 1,600 bushels in Morris Cove, and Fair Haven became a great oyster shipping center.910111213

The republic of New Haven, Charles H. Levermore, 188640

“The stranger within New Haven's gates is immediately impressed by the vista across the broad and beautiful Green”

Old paths and legends of the New England border, 19076
