Horse-power Thrashing-Machines. 
The entry for trial of horse-power thi'ashing-machines were Unusually 
small, bt'ing only three in number. The introduction of steam-power for 
thrashing has so limited the demand for these machines that little attention 
seems to be paid to their manufacture. The trials were conducted without the 
dynamometer, and in awarding the prize we were mainly influenced by the 
quality of the work. The competitors were : —

The prize of 20^. \\as awarded to Messrs. Wallis and Haslam. 
Steam-power Thrashing-Machines. 
Owing to the non-attendance of several of the leading manufactiu'ers, there 
were fewer machines entered for trial than on previous occasions : this is to be 
regretted, as we think it of some importance to the public to know whether 
the machines which had prizes awarded them at the Chester meeting still 
maintain their position. In offering the jjrize in Class III. the Society definitely 
stated that no machine could compete which could not be driven by 8-horse 
power. To ascertain correctly the power taken by each machine we had the 
assistance of Messrs. Appold and Amos, jun., who worked the dynamometer 
throughout tlie trials, thereby relieving us of great responsibility. Tlic number 
of machines entered for trial was 19, of which 4 broke down, 9 exceeded the 
prescribed power, and G only could compete for the prize. In the first trial 
we determined to decide the merits of each by a system of points, and annexed 
is a tabular statement of the results. 
Of the 6 machines eligible to compete for the prize we selected 4 for a second 
trial. In order to arrive at a just conclusion, and a.scertain correctly their 
good or bad points, we decided that each machine should be subjected to a trial 
I if 30 minutes, and the power required to drive it should be recorded by the 
dynamometer. We allowed each exhibitor to be solo manager of his machine, 
with the view to make its performance as eft'ectivc as possible. The quantitj'' 
of corn sacked was then weighed, and from the chaff, calder, and other refuse, 
\vas taken by one of Messrs. Hornsby's dressing machines all the corn which 
otherwise would have been tluown away ; this also was weighed and noted 
down against each machine. It was extremely gratifying to hear each 
exhibitor express his approval of this test, and from the accompanying Table, 
coupled with the workmanship, price, and general performance of each machine, 
^ve awarded the prizes as follows, viz. : —
