The manufactures of Iron are entitled to pre-eminent rank. None are more essential in their kinds, nor so extensive in their uses. They constitute, in whole, or in part, the implements or the materials, or both, of almost every useful occupation. Their instrumentality is every, where conspicuous. It is fortunate for the United States that they have peculiar advantages for deriving the full benefit of this most valuable material, and they have every motive to improve it with systematic care. It is to be found in various parts of the United States, in great abundance, and of almost every quality; and fuel, the chief instrument in manufacturing it, is both cheap and plenty.
