and lower rail R, for raising or lowering the internal part of the mill, for the purpose of obtaining a coarser or finer ope- ration in the works. O, the hopper affixed on the outer cylinder, to receive the several articles that are to pass through the mill: this hopper may be composed of wood, or any other proper materials. P, the hollow conical covering over the inner part of the mill, which may be of the same kind of materials as the hopper O. The frame for supporting the works, consists of posts, QG², let into the ground at four angular points, to which are connected the lower rail R, and two upper rails R, crossing each other at right angles. Be- tween the posts are to be fitted, from the under side of the cylindrical body F, to the floor, wire sifters, for the purpose of separating the finer from the coarser parts of the articles passing through the mill.

Having thus explained the principles of my invention, and the manner in which they may be applied, I observe, that the materials may be of varlous qualities, sizes, and substances, capable of being applied to the uses, strength, and purposes, for which they are intended; and that the sizes and strength of the several parts of the machine, or mills, may be varied according to the nature and extent of the works to be per- formed, therefore are not subject to any precise dimensions, form, or quality of materials, and may be worked by a horse or horses, water-mill or wind-mill, steam-engine, or any other proper power, and may be applied, not only to the pur- poses above-mentioned, but likewise will be particularly use- tul for grinding barilla for soap-boilers and others, clay for making bricks and tiles, and may also be applied to many other serviceable purposes.

ON SPANISH SHEEP. To the Editor of the Agricultural Magazine.

SIR, AM as ready as Mr. Bartley, or any man in this king- dom, to extol those very able, numerous, and patriotie friends to agriculture, Sir John Sinclair, Lord Somerrille, Lord Sheffield, the Duke of Bedford, Mr. Coke, and a list so long, that I am happy in saying my paper would not con- tain it. I am fully persuaded, that nothing whatever is of equal importance io the British empire, and, perhaps to the world,(of which she seems the bulwark) with the encourage- ment of British and Irish agriculture, and the improvement of our waste lands and breeds of live stock. Jtherefore censider the advantages which will result to the country from the merir⸗ torious exertions of the above patriots, as incalculable. Pro- bably, the unparalelled prosperity of Great Britain, has in a
