ed in respect to the mere power of separating the grain from the 

 straw.: hence the chief difference between them is in durability, 

 workmanship, power required to work them, and cost. 



Emery & Go's machine is thoroughly built, the journals run 

 in Babbett metal boxes, and consuming no more power than 

 others of its class, has the advantage of economy in the first cost.

 Badgers Thrasher and separator did not entirely fulfil the ex- 

 pectations formed by many. The differences, however, between 

 this and the more perfect machines on the ground, need not pre- 

 vent its use," for these differences are slight though palpably suffi- 

 cient to make a discrimination.

The data in this table show that the greatest effect produced 

 by a given draft is by the Wakeley power : in other respects also, 

 this seems to be a good machine. It is constructed on what has 

 been termed the "sun and planet system''; the teeth are carefully 

 formed, upon true principles; friction is reduced, and the work- 

 manship throughout is substantial. 



HORSE POWERS OX THE ENDLESS CHAIN PRINCIPLE. 



In the absence of Dynamometers applicable to a determination 

 of the force required for operating horse powers on the endless 

 ohain principle, youj committee adopted the following plan :
