The difference, as shown by the table, in the power required 

 by different threshing-machines for threshing a given quantity of 

 straw, which was 1 to 3 at Exeter, is not much less now, being 

 still as high as 1 lo 2^. The speed, however, with which the straw 

 is passed through the machine must not, of course, be made the 

 sole test of excellence. Clean threshing is a most material point, 

 in which some machines are very deficient, as is proved after rain 

 by the grassy verdure of a straw-heap so threshed. Thus the 

 easiest working machine, Mr. Crosskill's, seems to have gained 

 that ease at the expense of its efficiency, as appears in the column 

 which remsters the cleanness of the threshinor. On the other hand, 

 clean threshing may be obtained by beating the sheaves too 

 roughly, as must be the case with Mr. Hornsby's, which bruises 

 the straw, and, what is worse, breaks the grain. Still, the power 

 required by the three prize machines averages only about 12, while 

 the maximum of power required is just double, namely, 24, by 

 Mr. Smith's, which, therefore, of course wastes half the power, 

 whether of horses or steam, that may be applied to it. 



A separate trial, it will be seen, was made with barley. Long 

 as the threshing-machine has been known, the maltsters in most 

 counties refuse to buy barley unless threshed by the flail, because
