[166] When Barley, among which the St. Foin is planted in a dry Summer, is great, there are few Farmers that know till the next Spring, whether the St. Foin succeeds or not; because the young Plants are not then visible; unless it be to those who are accustomed to observe them in all the Degrees of their Growth. I have seen a Field of Ten Acres of such, wherein, after the Barley was carried off, nothing appeared like St. Foin; but when by the Print of the Chanels I searched diligently, I found the small St. Foin Plants thick enough in the Rows; they had no Leaves, they being cut off by the Scythe; no Part of them that was left had any Green Colour; but from the Plants there came out many Sprigs like Hog’s Bristles, or like the Beard of Barley: This whole Piece of St. Foin succeeded so well, that the Third Year its Crop was worth Three Pounds _per_ Acre, the Land being good. St. Foin drill’d betwixt Rows of Barley or Oats, always is stronger than when drill’d amongst Corn that is sown at random; and therefore is in less Danger of being kill’d by the Lodging of the Corn; neither is the Corn in Rows so liable to fall as the other. The Quantity of Seed to be drill’d on an Acre will depend, in great Measure, upon the Goodness of it; for in some bad Seed, not more than One in Ten will grow; and in good Seed, not One in Twenty will miss; which is best known by stripping off the Husks of a certain Number of Seeds, and planting the Kernels in Earth, in the manner directed for finding the proper Depth to plant at, which, in this Case, let be half an Inch: This being done, the Quality of the Seed will be known. But until frequent Trials have furnish’d Experience enough to the Planter to know the Difference, let him observe, that the following are good Signs; _viz._ The Husk of a bright Colour, the Kernel plump, of a light-grey or blue Colour, or sometimes of a shining black; yet the Seed may be good, tho’ the Husk is of a dark Colour, if that is caused by its receiving Rain in the Field, and not by heating in a Heap, or in the Mow; and if you cut the Kernel off in the Middle, cross-ways, and find the Inside of a Greenish fresh Colour, it’s surely good; but if of a yellowish Colour, and friable about the Navel, and thin, or pitted, these are Marks of bad Seed. The Quantity, or rather Number of Seeds convenient to drill, ought to be computed by the Number of Plants[167] we propose to have for making the best Crop, allowing for Casualties[168]. [167] Not that we need to be so exact as to the Number of Plants, whether they be Two, Three, or Four hundred upon a square Perch. Neither is it possible to know beforehand the precise Number of Plants that may live; for sometimes the Grub kills many, by eating off the first Two Leaves.
