even at the low figures that I have recorded, such a ma- 

 chine as Harder's, or Palmer's Climax, or Wheeler, Melick 

 & Co.'s, will he found to be a great labor-saving machine 

 for thrashing all kinds of grain. 



" There is one consideration that should not be over- 

 looked in this estimate, which is the much greater amount 

 of labor performed, Avith far less fatigue. When one la- 

 borer can perform the work of two or more workmen Avith 

 less fatigue than has usually been required, a great point 

 is gained." 



J. Stanton Gould, estimating from a large number of 

 statements that a saving of five per cent of the grain is 

 effected by using the machine, over thrashing by the flail, 

 computes the aggregate annual saving in the United States 

 to be over eight million bushels of wheat, two million 

 of ryCj eight million of oats, and nearly a million of barley. 



For farms of moderate size, the endless-cham powers
