This was the original milling-machine.
As in the case of so many important inventions, however, but little, progress was made for a while, and the original invention and inventor were almost forgotten, when, nearly a century after Moxon, the necessities of the times caused the revival of the invention to be made with special ref- erence to iron.
In the year 1751, the engineer of the Marly Water-Works on the Seine, France, contrived and put in execution a machine for planing out the wrought-iron pump-barrels employed in that work.

The present metal-planing machine is an application of the slide-rest, which was invented by General Sir Samuel Bentham and described in his patent of 1793.
The planing-machine d
