I esteem St. Foin to be much more profitable than Clover, because St. Foin is never known to do any perceivable Damage to the Corn amongst which ’tis planted; but Clover often spoils a Crop of Barley[190]; and I have known, that the Crop of Barley has been valued to have suffer’d Four Pounds _per_ Acre Damage by a Crop of broad Clover’s growing in it in a wet Summer: In a dry Summer both Sorts of Clover are apt to miss growing; and if it does grow, and the next Summer (wherein it ought to be a Crop) prove very dry, it fails on most sorts of Land, tho’ it was vigorous enough to spoil the Barley the Year it was sown; at best, ’tis of but very short Duration, and therefore is not to be depended on by the Farmer, for maintaining his Cattle, which the broad Clover will also kill, sometimes by causing them to swell, unless great Care be taken to prevent it. The broad Clover is esteem’d a foul Feed for Horses. The Hop Clover is gone out of the Ground sooner than the broad Clover; I never knew it cut more than once: Indeed Cattle are never swollen by feeding on it; but then it affords but very little Feeding for them, except the Land whereon it grows be very rich. [190] But this Damage may be prevented by drilling the Clover after the Barley is an Handful high or more; for then the Barley will keep it under, and not suffer it to grow to any considerable Bigness till after Harvest; nor will this Drill, being drawn by Hand, do any Damage to the Barley. St. Foin is observ’d to enrich whatever Ground ’tis planted on, tho’ a Crop be taken off it yearly. Poor Slate Land[191], when it has borne sown St. Foin for Six or Seven Years, being plow’d up, and well till’d, produces Three Crops of Corn; and then they sow it with St. Foin again. [191] The Poverty of this sort of Land, lying upon Slate or Stone, generally proceeds from the Thinness of it; and, if it were thicker, it would be good Land: Much of this Earth, being dispersed among the Crannies or Interstices of the Slate and Stone to a great Depth, is reach’d by the Tap-roots of the St. Foin, but cannot be reach’d by the Roots of Corn; and therefore, when constantly kept in Tillage, is of small Value: Upon which Account such Land is greatly improveable by St. Foin, even when sown in the common manner. Rich arable Land was planted with it, and mow’d annually with very great Crops (’twas drill’d in Nine-inch Rows, with Six Gallons of Seed to an Acre; One Crop of it was sold at Four Pounds _per_ Acre): This, after about Seven Years, and in full Perfection, was plow’d up by a Tenant, and continued for many Years after so rich, that, instead of dunging or fallowing it for Wheat, they were forc’d to sow that upon Barley-stubble, and to feed the Wheat with Sheep in the Spring, to prevent its being too luxuriant.
