As the ſeaſon for Hay-making is not far diſtant, the Editor thought it his duty to lay before the Public two intereſting Papers on the ſnbjett reſpeét- ing metho&s lately praiſed on the Continent with ſucceſs; one for making Meadow-Hay, the other Clover-Hay; both which will be found to contain much uſeful information, to treat the matter in different points of view, and elucidate its theory.

DESCRIPTION OF À NEWLY INVENTED HAY-

HARROW, BY C. BLOYS VON TRESLONG.

(From the Ti'anſaëions of the Rotterdam Society, Vol. II. p. 88.) With a PLATE.

HIS Harrow is made of wood, in ſize nine feet broad by

| four feet four inches long. The upper and under rails

are two or three inches ſquare, and nine feet long, faſtened to=

gether with three pieces five inches broad, one inch and a quar=

ter thick, and four feet four inches long, one in the middle and

the other two on each fide, ten inches from the ends of the rails, asat AA,,

To give this machine yet more ſtrength there muſt be two diagonal braces B B; in each of the rails muſt be five teeth of úx inches long in the clear, and chree quarters of an inch diame- ter, placed as in the plate, and ſloping outwards to the rear, for if they ſlope forward, or are upright, they will cluſter the graſs too much in heaps.

The teeth might be made of iron, and of courſe a little ſmaller, which I intend to try this year; however this depends on fancy, if care is taken to make the Hay-Harrow light enough, leaſt ic ſhould ſink through the hay or gra(s into the ground,

The Hay-Harrow is drawn by a horſe, upon which a man rides, who takes care to(catter or ſpread the graſs by harrowing it from the ſwath, as thick as is neceflary to dry it.

That the graſs by the means of this Harrow may be turned quicker and much better than can be done in the uſual manner is evident; for with this machine one may eaſily turn the hay of three acres in one hour, which will be well mixed; for ſuppoſe that the upper part of the hay is dry at nine o’clock in the morn= ing, it may be turned at ten o’clock, ſo that one can have the beneht of. the greateſt heat of the ſun; on the contrary, when the hay is turned in the uſual way, the beſt time of the day will be pafled before the laſt of the grals is touched, and part of the graſs will be too dry, when the other is noc half dry enough,

On a warm and windy day one may keep the horſe confſtantlz going. Wehen the laſt of the acre is turned, begin again with
