[168] Many even of the best of Seeds, both sown and drill’d, are liable to Casualties, but not equally; for about Twenty-eight Years ago, my Servants (being prime Seedsmen) had a Fancy in my Absence to try an Experiment of the Difference betwixt sowing and drilling of St. Foin; and in the Middle of a large Field of my best Land they sow’d a square Piece of Three Acres, at the Rate of One Bushel to an Acre, not doubting but, by their skill in sowing even, it would succeed as well as if drill’d; but it succeeded so much against their Expectation, that the Land all round it, which was drill’d at the same Time, with the same Proportion of the same Seed, brought extraordinary good Crops of St. Foin; but the sow’d Part was so very thin, that tho’ it lay still with the rest for Eight Years, it never was a Crop, there not being above Three or Four upon a square Perch, taking the Three Acres all together: Not that it can be supposed, that the sown would always meet with so many Casualties as this did; for then Eight Bushels sown to an Acre might have been too thin, and much thinner than all the rest of the Field was, tho’ drill’d with only One Bushel to an Acre: And ’tis often seen, that when an Acre is sown with seven Bushels of Seed, the St. Foin is as much too thick, as that sown with One Bushel was too thin. I do not know, that of the many hundred Acres of St. Foin, that have been drill’d for me, ever one Acre was too thin, except when planted with Wheat: The young Plants were kill’d by the Frost. In drilling St. Foin not to be ho’d, and before the Ploughs of my Drill were so perfect in making narrow Chanels as they are now (for, when the Chanels were open, they had Six times the Breadth, wherein Part of the Seed was wasted), then my Quantity was One Bushel to an Acre, sometimes Six Gallons. But a single Acre (in the middle of a large Field of St. Foin) being drill’d late in _October_, the frosty Winter kill’d at least Nineteen of Twenty Parts[169] of that Bushel. At first it made such a poor Appearance, that ’twas by mere Accident, or it had been plow’d up for a Fallow; but, missing of that, a few Plants were perceiv’d in the Summer, which by their Singleness grew so vigorous, and so very large, that the Second Year of Mowing it[170] produc’d a Crop double to the rest of the same Field, which was drill’d in the Spring, with the same Proportion of Seed, and none of it kill’d: tho’ all this Field was a much better Crop than some that was sown in the common Manner, with Seven Bushels to an Acre. I have generally observ’d the thin[171] to make the best Crop, after the First or Second Year. [169] But I believe, there might remain alive Three or Four Plants to each square Yard, standing single, and at pretty equal Distances. [170] But _Note_, This Acre was dunged, and in better Order than the rest.
