 body of the saw after the teeth had passed and make 

 the work very laborious. When a saw is properly set 

 it should pass through the wood easily.

The teeth of the ripsaw are also set, but, as will be 

 seen in the sketch, the bottoms are flat like a chisel 

 instead of pointed like those of the crosscut teeth. 



Beside the end views of the two kinds of teeth, 

 the side views, which are also different, are shown in 

 Figs. 12 and 13. 



We are inclined to think of the saw as a very com- 

 monplace article, yet a careful examination will prove 

 that the greatest care and skill are needed in its man- 

 ufacture. Observe that the body, which must be of 

 the best steel, tapers, being considerably wider at the
