2..° fy 4 sare see a ie Harrowing, in general, is by much the beft performed by driving the horfe or horfes

by whip reins of fufficient length to permit the perfon employed to walk after the har-

et

rows. By this management he can clear the harrows as occafion may require, and proceed in his bufinefs with greater difpatch. It is now a pretty general obfervation. among the intelligent cultivators of land, that the bufinefs of harrowing is more effec- tually and more advantageoufly performed by fingle-horfe harrows, than by fuch as ree quire two horfes. In the attachment of thefe implements to the power which is to draw them, the common method is by a ftrong fort of ftaple fixed to one of the corners of the harrow by a bolt; but a mode which appears more advantageous, is that of

connecting the muzzle with a perpendicular pin at one corner of them*. ROLLERS.

TuEsE are moft commonly made of wood, caft-iron, or{tone, according as one or other fort of material is moft ready and eafy to be obtained; and are of different fizes and weights, in order to fuit different purpotes.. In conftru€ting heavy rollers, the workman fhould be careful that they have not too great a diameter, what- ever the material be of which they are formed, as the preflure is diminifhed where the implement is of very large fize, by its refting on too much furface at once, except an addition of weight in proportion be made. By having the rolier made fmall, when loadedto the fame weight, a much greater effeét will be produced, and a confiderable faving of expence be made in the conftru@ion of the implement. All the larger forts of rollers fhould have double fhafts, in order that they may be drawn by two horfes abreaft; and fuch as are employed for arable lands fhould have a fcraper attached to them. This addition faves much time, and prevents the driver the trouble of conftantly feraping the machine, elpecially in wet feafons, and elayey tenacious lands. Strong frames are alfo neceflary for rollers; fo that proper weights may be put upon them; and open boxes or carts placed upon them may tometimes be requifite, in order to contain any additional weight that may be though
