An Acre contains 7,840 square Yards; but, for Paths, Wastes, and inclosing, I would allow 1,800 Yards, not to be employed; As the first Year they will be little more than fibrous, I would allow three Years for their Growth, tho’, if another Year was added, the Crop by an Increase would sufficiently reward, not only as to Quantity but Quality; as the best of Lands are not required; I would state the Expence of that Culture as follows, Three Years Rent at 5_s._ the Acre, 0 15 0 Plowing twice and Harrowing, 0 12 6 Planting, 0 7 6 Houghing, 1 Digging up the Roots, 1 ------ Total 3 15 0 Suppose each square Yard, should produce but the Moiety of what before was mentioned, and sold but at three farthings the Pound, the Amount will be 27_l._ 3_s._ 6_d._ from whence a Profit ariseth beyond most of our Cultures, now in general Use, and the Tannage may be accomplished, at about a Moiety of the present Expence. Probably, this Estimate of the Charge and Profit, may not be so exact as to be strenuously defended; but if defective, there is Room enough for any reasonable Addition or Deduction, without much Prejudice to the Argument; different Soils, often one and the same will be attended with different Charges; The finer, the Earth is made, or the more it is broken, before Planting the better Vegetation succeeds; at first shooting up of the Herbage, particularly where the Ground is foul, houghing, or pulling up the large Weeds, will be necessary, that the Growth of the _Tormentil_ may not be chequed; in a little Time it will clear its self. As the Roots run superficially, not streeking at most 5 or 6 Inches in perpendicular Depth, the Charge of digging them up cannot be so much, as that which attends Potatoes. The Propagation may be effected by planting the Crowns of the Roots, (that Part, from whence the Herbage ariseth) in either Autumn or Spring, in the same manner as Horse Raddish, splitting the Crown, so as to leave a Bud on every Slice, then setting them in the Ground, about an Inch in Depth and allowing each Set, 5 or 6 Inches square of Ground. When you take up a Plantation, you will have an Abundance of small Roots that arose from the shedding of the Seed, and from the Runners, that will scarce be worth the Drying, but very proper for Planting: If you cut from either Extremity of the Root, a Piece of about half an Inch in Length, it will grow very well. The whole Root, if cut into such Pieces, may be planted. In all these I believe the Charge of Planting might be saved; if you scatter them before Harrow, the passing of that over them, will cover them with Earth sufficient; or at least, the most Part of them.
