Book excerpt: Excerpt from A Popular History of American Invention, Vol. 2: Material Resources and Labor-Saving Machines After a hundred years of iron-making in the colonies, Parlia ment, in 1750, passed a law forbidding them to build any. Mill for rolling and splitting iron, or any furnace for making steel. This confined the colonists to pig and bar iron. They could not lawfully cast anchors and kettles, or make horseshoes, ham mers, crowbars, and iron parts for farming tools, wagons, ships, and the like. Articles of steel, such as knives and scissors, and implements of rolled sheet-iron must all be imported from Eng land. This was a costly proceeding; the colonists could have made them more cheaply themselves. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
