Early on the morning of Tuesday, the 20th of July, the marshal (Wm. Johnson, Esq., of Ontario,) announced that the Mowing Machines were on the ground, ready for trial. Numbers corresponding with the lots surveyed and marked on the meadow were drawn by the exhibitors, and each machine was directed to its station according to the number drawn.

A view of the field at this time, with the array of Mowing Machines of varied construction, claiming to save labor, and accomplish better work than had hitherto been effected by the farmer, presented a scene of interest, not only to the agriculturist and mechanic, but also to every man whoes views extended to the advancement of his State and of the nation. It could not escape the observing mind, that, in this State, producing annually about four millions of tons of hay, there was on that field, machines having the capacity to add, by their use, an annual income to the farming population of more than a million of dollars; and extending these views beyond the limits of our State, applying them to the Union, whose surface gives annually more than thirteen millions of tons of hay, how important becomes the investigation of this class of machines, thereby exhibiting to the agriculturist their powers, uses, and advantages.*

Estimating the hay crop of the United States, as per the consus of 1850 at 13,605,384 tons, the average cost of cutting and making at $1 per ton, and the saving, by use of Mowing Maohines, at one-forth of the present cost, the annual gain would be $3,401,346.

The duty of the judges might have been confined strictly and fairly to a report of the successful machines, yet as agricultural machinery may be esteemed as being in its youth, immature, as ingenuity and skill stamped their features on most of the machines presented, it seems alike due to the mechanic and farmer, to present a notice of the unsuccessful as well as of the more favored machines.

The annexed table exhibits, in a condensed form, the distinctive characteristics of the several Mowing Machines, and embodies the essential facts needful for a generally correct estimate of their respective merits:

STATEMENT of the trial of mowing machines, at Geneva, July, 1852.

• This machine was not presented until the second day of trial, at a late hour.

It will be perceived, from the data set forth in this table, that the chief competition rested between Manny, No. 2, and Ketchum, No. 3.

The judges did not feel entirely satisfied with the trial thus far, as the grass did not present the resistance to be encountered in average crops. The exhibitors were notified to present their machines on the following morning at 8 o'clock on the farm of Mr. Sherman, when a second trial would be made in heavy grass. At the appointed hour the judges were on the ground, and caused each machine to take its station as it arrived and was adjusted. The KETCHUM MOWER led off handsomely, opening a double swath. MANNY'S MOWER entered in the same manner and opened a double swath. So well was the grass cut by both machines, that no decided preference could be given to either-and it was manifest that no labor with a scythe could perform the work as well.

Both machines then entered upon the low grounds, encountering high and thick grass, portions being lodged and tangled, lying in all directions; they were directed to cut double swaths through this grass, and then to follow each other laying their swaths side by side. Ketchum's machine performed the task without interruption; Manny's machine was stopped by cutting through a hummock, which lodging on the knives, pressed down the standing grass, preventing a free cutting action; a second interruption occurred when entering the swath, from inattention to clearing the cutting knives. Aside from these casualties the work was well performed.

The quality of the work accomplished by both machines could not fail to satisfy any farmer, and was better done than could be performed by the most expert mower with a scythe.
