ing apparatus located in the rear of the cutters, from whence the products are carried to a cleaner, which separates the grain from the chaff, the latter being scattered on the ground, while the former is delivered into bags, which are tied up ready to send to market. It will be apparent from this description of its operation, that this machine effects-and that in a most perfect manner-the operations that are now performed by three distinct machines, at a great saving in the cost of the apparatus, the labor of attendance, and the time required for the purpose-the latter being generally the most important item of the three, as a crop of grain may be lost, or at least materially injured, by being exposed to stormy and unpleasant weather, through the delay incident to its being gathered by the process at present in use.

The machine is propelled by a team attached to a shaft jointed to the hinder part of its platform, and it is guided by an attendant operating a steering wheel connected to the hind truck wheels, so that it is readily controlled and guided, and it effects its operations with less power, and by the attendance of a less number of hands than would be required to effect the same operations separately, as four horses and three men will operate a machine cutting nine feet in width, and traveling over an area of twenty-five acres per day delivering the grain grown upon that quantity of land in a state ready for market.

The question, whether it is more profitable to the farmer to harvest his grain in a green or a perfectly ripe state, is yet a mooted one; but it is claimed by the inventor of this machine, that the grain when fully ripe, not only weighs heavier to the benefit of the producer-but possesses a greater amount of nutritious matter to the advantage of the user: that it is less liable to waste in gathering, and leaves the straw of greater value, whether it is gathered for use or left in the field to rot for manure. The correctness of these assumptions can be best tested by experience; but we believe they are in the main correct, and will be proved to be so by extended experiment.

The company claim for this improvement, that by its extreme portability, simplicity and strength, is is fitted to render important aid in cutting down trees. It cuts close to the ground, thus saving wood, may be adjusted so as to cut at almost any angel, leaves the butt ready for the mill, does its work with great rapidity, runs easy, cannot [AM. INST.]

well get out of order. By using Spur Gear Wheels, instead of beveled, the motion is reversed, and the machine adapted to sawing off logs. Both of which machines are now being made in the most substantial manner.

Throughout the region where wood is plentiful and required for fuel, the application of a movable one horse power to this machine, to saw the trees or logs into lengths suitable for the stove or locomotive, will greatly cheapen the process of preparation, leaving it in better condition, besides saving a large percentage of wood now wasted by the axe.

Hinckley & Egery, and Geo. H. Reynolds, Bangor, Maine. This engine called the ENDEAVOR, exhibited at the 28th Annual Fair of the American Institute, held at the Crystal Palace, was designed by Geo. H. Reynolds, Medford, Mass., a practical engineer and machinist, and was built at the well known works of Hinckley & Egery, Bangor, Maine.

Who claim the following improvements in the cut-off valves, pillow blocks and slides.

The improvements in the cut-off consist in the employment of a pair of perfectly balanced valves, secured to the back of the main slide valve, through which the steam passes in its way to the cylinder. These balanced valves are moved by the motion of the slide valve, and travel therewith. The device by which they are opened and closed is the most simple and effective of any known method of working the cut-off of steam engines. As the slide valve approaches the point to admit steam to the cylinder the cut-off valve is opened by its motion by coming in contact with fixed stops at the bottom of the steam-chest, and remains open until it comes in contact with movable stops, which are operated by the governor, when it is instantly closed and the steam cut off.

The improvement in the pillow block consists in clasping the bushings of the boxes, which part vertically in an iron frame which bolts firmly to the bed plate. The advantages of this over the ordinary style of pillow block are, that the side wear may be all taken up by screws taped through the side of the clasp, and that the entire box may be removed from the engine without raising or in any manner disturbing the shaft or any other part of the engine; while in the ordinary pillow block the shaft, with its fly wheel and all connections of the crank shaft, have to be removed.

The slides are constructed so as to come even with the top of the cross-head, thereby giving double the amount of surface sidewise, and enabling us to make the oil cup to lubricate the same, stationary upon them. [A gold medal awarded.

REPORT OF THE JUDGES ON FISHER'S STEAM

CARRIAGE.

We, the undersigned, judges on the steam carriage of J. K. Fisher, appointed by the Managers of the Twenty-eighth Annual Fair of the American Institute, held in New York, October, 1856, beg leave to report:

That we have carefully examined the plans and devices submitted to our inspection, and decide

1st. That the said plans and devices embody a novelty of arrangement of parts possessing great advantages over any former plans and devices for the same purpose.

2d. That the said plans and devices embody various new and essential advantages which overcome many of the old difficulties in the use of the steam carriage, and give hope of its success on smooth, hard and level roads.
