Immediately following the bargain of Dr. Cutler with Congress, the Associators prepared to migrate _en masse_ to their purchase. What the hardy spirits among the country people of the South Atlantic States had been able to accomplish by individual initiative and sheer endurance, the town-dwellers of the North Atlantic States did more systematically and rapidly by concerted action. Organisation and government protection saved the Ohio Associators from such experiments of colonisation as had frequently led to Indian captivities and abandoned settlements in Tennessee and Kentucky. The project of a line of forts along the frontier settlements, conceived during the Indian and Revolutionary wars, assumed shape after the first sale of public lands had really been consummated. Forts McIntosh, Steuben, Washington, Harmar, Vincennes and Massac, were speedily erected or garrisoned, thus guarding the length of the Ohio River, the pathway to the North-west. By subsequent Indian treaties, additional reservations were secured and forts scattered throughout the territory at portages and along the river highways. Under this protection, the Ohio Company sent out its band of artificers to erect dwellings and a stockade for the first settlement. Scarcely a year was allowed to elapse after the purchase until Marietta was founded on the Ohio at the mouth of the Muskingum by the veterans of the Revolutionary War and their friends. It was 170 miles down the Ohio beyond the outpost of civilisation at Pittsburg. Similar settlements were speedily founded on other purchases and on the military lands. [Illustration: DR. CUTLER'S CHURCH AND PARSONAGE AT IPSWICH HAMLET, 1787. The rendezvous from which the first company started for the Ohio, December 3, 1787.] The national governor and judges for the Northwest territory in due time created a set of laws, established courts, and erected local governments. The latter was effected by applying the county system, familiar to the people of the Central and Southern States, to the land survey county, and by giving to the township, a unit in the survey system, some of the functions of the New England town. By this happy combination, settlers from any part of the old States would find a local government with whose forms they were to some extent familiar. The Symmes purchase on the Ohio below the Ohio Company's grant was opened to settlement, as was the Virginia Military tract lying between the two. Through Pittsburg, "the gateway of the west," came a throng of pioneers to float down the Ohio to the land of promise. The United States forts protected them on the northern or "Indian side" of the river. In 1786, no less than 117 boats were counted passing Fort Harmar.
