Cultivation of Arable Land.—Potatoes. 615

diftant from each other. The plough is then to be run on both fides of each drill, to throw the earth which was raifed-out of it upon the potatoes. This operation will elevate it in the middle, and caufe it to lie floping on each fide like the roof of a houfe. The bufinefs is thus complete until the fiems of the potatoes begin to make their appearance above ground.

‘But in the Weft Riding of Yorkthire, where the culture of the potatoe is well performed, according to the Report of that diftri&t, after the land has been properly prepared, the beft cultivators begin to ridge it up by ploughing a fur- row round it down, and then taking a fuitable diftance according to the nature and qualities of the foils, as from about two feet eight inches to three feet, fuch as are rich and fertile requiring more fpace of ridge than fuch as are poor and exhaufted.‘The manure, where neceffary, is difpofed with regularity in rows by means of a Jabourer with a fork, in the ridges, the potatoe fets being then placed at fuitable diftances upon it, and covered by the plough.

The method recommended by other cultivators in the northern parts of the ifland, after much experience, is, after the ground has undergone a thorough preparation, and is made perfeétly level by repeated ploughing and harrowing in different direGlions, to draw ftraight parallel furrows by means of a double earth-boarded plough, drawn by a fingle horfe, at the diftance of two feet and an half from each other. This operation is performed in the moft corre&t man- ner, by pafling the plough twice in the fame tra€ét, which, when the land lies floping or uneven, fhould be down hill the firft time. The manure is then brought on in carts from the upper fides of the fields where they are hilly, the horfes paffing in one furrow, and each of the wheels in others on the different fides; they are then emptied by the drivers, who walk behind them with crooked three-pronged forks conftruéted for the purpofe, leaving it in fmall heaps in the furrows in which the horfes go, in fufhicient proportions for the three drills. It is then divided and fpread out in the different rows in as equal a manner as poflible by women and children, the fets being put in upon it at the diftances of about twelve inches from each other, the whole afterwards covered in by the plough, by fplitting the ridges betwixt the rows, pafling twice in the fame traé& as in opening the furrows for the rows.

There is another method of planting this root, that prevails pretty generally in the more dry diftri€ts, which is that of fpreading the manure over the whole furface of the land in an equal manner after it has been well prepared by twice ploughing and harrowing; the fets are then planted in every third furrow, the dung and fine mold being turned upon them by the plough. This mode of fet-
