TO JOHN HEATHCOAT, of Tiverton, in the county of Devon, Esq., for his invention of certain new and improved methods of draining and cultivating land, and new or improved machinery and apparatus applicable thereto; which machinery and apparatus may be applied to divers other useful purposes.-[Sealed 15th May, 1832.]

THE subject of this patent is, in a national point of view, particularly as regards Ireland, one of the most important that has been introduced to the public. It is principally designed to afford the means of cultivating such boggy waste lands as are of too spongy a character to sustain the feet of horses.

The apparatus consists principally of a locomotive steam-engine sustained upon a platform, which moves very slowly over the surface of the bog, upon a very

broad endless band, which is nearly impervious to water, and presents such an extended surface as to prevent its sinking. From this machine ploughs and other implements of husbandry for cutting and turning over the surface of the moss are worked out and in, to the distance of a quarter of a mile on each side at right angles to the course in which the engine is slowly advancing, and the power of the steam impels the ploughs in place of horse or other manual labour.

Upon the merits of this invention and its important advantages volumes might be written, and no doubt will be; but our limit at present only allow us to give the details of the contrivances as set out in the specification, observing, however, that we have withheld our report under the expectation of being enabled to speak practically of the effect of its operation.

We have several times within the last two years witnessed the action of the machinery upon Red Moss, near Bolton-le-Moors, in Lancashire, under the superintendence of a skilful engineer, Mr. Josiah Parks, and have now the satisfaction of communicating to our readers the fact of its most unqualified success.

The new or improved methods of draining and cultivating land, consists in the employment of certain machinery and apparatus to be worked by steam or other power, for the purpose of ploughing, cutting, rolling, harrowing, trenching, and draining lands, and for effecting other operations of husbandry as are or may be performed by traction, which machinery and apparatus is particularly adapted for use on lands which cannot be so conveniently worked and tilled in the ordinary manner by the agency of horses or other cattle.
