Table C gives the performance of all the machines which 

 were adapted for steam power, and the trial was ccmducted as 

 follows : — Each machine was furnished with 100 sheaves of mown 

 wheat, and the time it took to thresh them, as well as the quality 

 of the work, with regard to clean threshing and the state both of 

 straw and grain, is given in the columns appropriated to those 

 details. The following attempt was made to place all the 

 machines on an equal footing as regarded motive power. Two 

 steam-engines were employed, and a communication established 

 between their boilers, one being used simply to generate steam, 

 the other both for this purpose and to drive the machines. By 

 this arrangement it was anticipated that the supply of steam would 

 be so great that the boiler of the driving machine could be kept 

 constantly supplied with steam of the desired pressure even whilst 

 the machines were at work, and on trial this was found to be the 

 case. At first sight nothing could appear more satisfactory than 

 this trial, as all the machines worked under an equal pressure of 

 steam, and the time they occupied in doing the same quantity of 

 work would seem to be the fairest possible test of their respective
