378 Report on the Exliibition and Trial of Implements 
Corn-Dressing 3Iachines. 
Since the introduction of the combined steam-thrashing and dressing 
machines into nearly general use, screening, blowing, and finishing are the 
most important operations in a corn-dressing machine. The first separation 
of the corn from the chaff and puise (usually called roughing) having already 
been accomplished by steam, it only remains to finish the work and make 
the corn ready for market. Eoughing is therefore only of a secondary cha- 
" racter. 
There were 19 machines entered for trial, the greater part being withdrawn 
after the first work of roughing, so that it will only be necessary to give the 
trials of a few, the result of which faii-ly established Messrs. Hornsby's claim 
to the premium.

Medals. 
With regard to the prize Xo. 32, " for the invention of any new imple- 
ment," &c., the Judges of the Miscellaneous venture respectfully to call the 
attention of the Council to the claims of Mr. Balke, for his newly-in\%nted 
hrmk for testing the jiower of fixed or portable steam-engines. The Judges, 
therefore, guided by the consulting and other practical engineers, desire to 
recommend the claims of Mr. Balke to a silver medal for his invention,

A glance at the yard showed clearly a general improvement in the construc- 
tion and workmanship of the implements. Makers are availing themselves of 
the use of improved tools in their workshops, and are enabled to turnout better 
work : this appeared very forcibly in the stands of some of the smaller 
exhibitors, showing that they are fast " treading on the heels" of the larger 
ones. 
With reference to steam-engine?, the omission of expansion-slides and" 
general simplification of parts, as recommended by the Society, has proved 
advantageous, the consumption of fuel in the jirize engine of this year being 
very little greater than in that of last year ; some sin)i)lification may possibly 
be adopted in portable thrashing-machines with equal advantage ; a less 
cumbrous implement of this kind is desiiivble. 
Among the novelties exhibited at this Meeting may be mentioned Davey's
