Shipbuilding and the saw-mill had early sprung from the domestic necessities of the people. The Dutch had made the windmill a striking feature in the landscape of New York. The people of Pennsylvania had been the earliest in the middle colonies to establish a press, and it had brought the paper-mill in its train, though after a long interval; for it was not till 1697 that the manufacture of paper began near Philadelphia, and not till thirty years later (1728) was the second mill established at Elizabethtown in New Jersey. The Dutch had begun the making of glass in New York city, near what is now Hanover Square, and in Philadelphia it was becoming an industry as early as 1683; though if one may judge from the use of oiled paper in the first houses of Germantown, the manufacture of window-glass began later. Wistar, a palatine, erected a glass-house near Salem, in West New Jersey, in 1740, and Governor Moore, of New York, in 1767, says of a bankrupt glass-maker in New York that his ill success had come of his imported workmen deserting him after he had brought them over from Europe at great cost. The presence of iron ore in the hills along the Hudson had been known to the Dutch, but they had made no attempt to work the mines, relying probably to some extent upon Massachusetts, where “a good store of iron” was manufactured from an early date. Towards the end of the seventeenth century, when the ore was tried, the founders discovered the iron to be too brittle to encourage its use. Lieutenant-Governor Clarke tried to arouse interest for the iron industry in 1737, and induced the general assembly to consider the advisability of encouraging proprietors of iron-works; but the movement came to nothing, and Parliament did what it could to thwart all such purposes by enacting a law “to encourage the importation of pig and bar iron from his Majesty’s Colonies in America, and to prevent the erection of any Mill or other Engine for Slitting or Rolling of Iron; or any plating Forge to work with a Tilt Hammer; or any Furnace for making Steel in any of the said Colonies.” When this act was passed in 1750 only a single plating-forge existed in the province of New York, at Wawayanda, Orange County, which had been built about 1745, and was not in use at the time. Two furnaces and several blomaries had been established about the same time in the manor of Cortland, Westchester County, but a few years had sufficed to bring their business to a disastrous end. In 1757 the province could show only one iron-work at Ancram, which produced nothing but pig and bar iron. At this same establishment, owned by the Livingstons, in the present Columbia County, many a cannon was cast some years later to help in the defence of American liberties. In 1766 we find a little foundry established in New York for making small iron pots, but its operations had not yet become very extensive.
