Letters Patent for the United States wore issued to ISAAC STRAUB, Cincinnati, Ohio, in the Year 1851 . .... , THIS ingcnious Mill cost the inventor much labor difference between cutting with chisel-like teeth and and expense; who, after many trials, can assure the scraping with Saw teeth, whose cutting, or rather public that his portable "King of the Woods" is scraping, edges stand at right angles with the fibers triumphantly successful. of the wood. At all events, the "King of the Many of our very best mechanics in the United lIVoods" cuts oak, beach or sugar tree, about as States have made fruitless attempts to produce a easy as poplar or pine. The question is settled by Portable Saw Mill, to make lumber with animal absolute trial and experience, whatever others may power. Mr. Page, of Baltimore, Md., produced a say to the contrary.

This Saw Mill differs from all its pre- power of the lower half. This, it would strike the decessors on many points of natLual philosophy: mind of any man, is a paradox; but, when we bear 1st.

The crank-pin is in a fly-wheel that carries the Saw. In this case, the fly-wheel is the llJallet.
