ABSTRACT
Michael Chevalier a French economist was the first in 1834 to arrive on an official inspection tour of public works in the States. The works which have hitherto almost wholly occupied, and still chiefly occupy, the attention of statesmen and business men in the United States, are those designed to form communications between the East and the West. The frames of the clocks are stamped out of sheet brass, and all the holes are punched simultaneously by a series of punches fixed at the required distances. Self-acting machinery and revolving cutters are used for making all the separate parts, and the tools are made and repaired in a machine-shop which is attached to the works. The Lowell railroad has been extended to Nashua, and an eastern branch is now completed to Haverhill, of which a continuation towards Exeter is now in progress.
