In the Field, when the Ridges are all of an equal Breadth, the best Way is to plant Two of the single Rows at once, by setting the Two Beams of the Drill at the same Distance asunder, as each of the Ridges is broad; and the Beast that draws it must go in the Middle of the Interval, planting a Row on each Side of it; but if the Ridges are very unequal, the Beast (a little Horse is best) that draws the Drill must go on the Top of a Ridge, planting one Row thereon; and the Drill for this Purpose is the same as the Turnep-drill, except that the Beam-share, Seed-box, and Spindle, are the same as those of the Wheat-drill; and ’tis but to take off from the Wheat-drill one of its Beams, and place it in the room of the Beam of the Turnep-drill, and placing the Cross-piece of the Turnep-beam (see Plate 5.) on this Beam, and also a short Wheat-hopper to be drawn by the Turnep-standards, setting the Wheels near enough together; _i. e._ as near as the Wheels of the Wheat-drill are, I mean those which plant Two Rows. Two Gallons of _Smyrna_ Wheat I judge will be Seed sufficient for an Acre, especially if planted early. Planting one Row upon a Ridge, I think is the most advantageous Method of all; but, not being able to get any _Smyrna_ Wheat (tho’ I have been often promised it), I have made no Trial of it; and I do not believe the Plants of any other Sort of Wheat are large enough for such single Rows. I am not quite a Stranger to this Wheat; for I have seen the Product of it, both in the Garden, and in the Field, above Forty Years ago. I am now making Trials, in order to know how much a single Row of White cone Wheat will exceed half a double one: For this Purpose, I cause one Row of the double, with the Partition, to be dug out with a Spade, in Part of every Field, Two or Three Yards in a Place: These I intend shall be hoed as the double Rows are; and where the Hoe-plough doth not reach, the Spade shall supply its Use. I do not expect this single Row will equal the double Row; but I am in no doubt but that it will produce more Grain than half a double Row. I cannot tell whether the Sort of Cone-wheat that sends out little Branches on each Side of the Ear, might not succeed tolerably well in single Rows; for its Ear is, when well nourished, larger than the Ear of the White-cone; tho’ not near so large as that of the _Smyrna_.
