Stewards. 
It had been previously determined that each of these 
machines, before going for further trial, should first be sub- 
jected to a run on the Dynamometer to test their comparative 
draught, which was done under the superintendence of Mr. 
Anderson, the Consulting Engineer to the Society. With this 
end in view, the knife of each machine was impounded on the 
completion of their respective two-acre plots of barley, so that 
the first run on the Dynamometer might be made with each 
knife in the condition in which it finished cutting. These trials 
commenced on Monday afternoon, and were, perhaps, some- 
what marred by a drizzling rain, which came on soon after 
they were commenced ; nearly the same condition prevailed next 
morning. The corn, though not very wet, was sufficiently damp 
to add something to the power required to drive the machines. 
Dynamometer Trials. 
In order to test the comparative draught of the selected 
machines, which had already gone through the ordeal of 
repeated trials, they were finally subjected to a dynamometer test. 
The nature of such tests has been reported in former 
Journals, and they were similar on this occasion. 
A portion of a field of wheat where the crop was most even 
was chosen. There was a fall in the ground in one direction ; 
so, to arrive at a fair estimate of the draught, each machine 
made two journeys up hill and two down hill. 
Those machines using a serrated knife made no alteration in 
their knives during the trial on the dynamometer. Those with 
smooth-edged knives did their first run with the same knife as
