NEW INVENTION.

Mr A. Macdonald, of the Milton Implement and Carriage Paotory, has (says the " Bruce Herald") invented an engine the objeot of which is to economise steam. His invention ia applicable to locomotives or stationary machinery, and Is suited for propelling steam on land or water. In the engines at present used the steam does not get to the piston in the proper way, as jt travels through a superfluous space before it reaches them. Mr Macdonald's invention utilises all available space, and there is no waste of steam. Instead of the steam being compelled to wander on each aide of the engine, thereby quite unnecessarily increasing its bulk without in any way augmenting its power, in the invention referred to the steam is conveyed directly to the piston. The four pulloys, which constitute the excentric and link motion in the old-fashioned engines, in Mr Macdonald's are reduced to a circular instead of a reciprocating motion, which drives the two engines when either " foregoing" or "backing"; in other words, this circular motion, which is peculiar to this invention, drives the two engines ahead or astern. The patterns have been designed and executed by Mr Macdonald himself, and the castings are his own work. He intends to invite the residents of Milton and district to a public trial of the invention.
