I have constantly found, that, upon doubling any Number of narrow Rows, having equal Number of Plants in each Row, the Crops have been very much diminish’d; and, upon leaving out every other Row, that is, lessening the Number of Rows to half, the Crops are increased; and where Two Rows are wide asunder at one End of a Piece, and near at the other End, the Plants are gradually less and less, as the Rows approach nearer together. We ought never to expect a full Crop of St. Foin the First Year[176], if we intend to have good Crops afterwards, and that it shall continue to produce such, for the same Reasons that must be given for planting an Orchard at other Distances than a Nursery. [176] But when it has been planted on rich sandy Land, and proper, it has produced very great Crops the first Year; but then the Summer wherein it grew amongst the Barley, must not be reckoned as the first Year. The common Error proceeds from mistaking the Cause of a great or small Crop. Where the Spaces betwixt Rows are wide (if there be not too many Plants in them) we always see the St. Foin grow large, and make the greatest Crop; but when ’tis young, or after cutting, we see room (as we fansy) for more of such Plants, to make a yet larger Crop; not considering that ’tis the Wideness of those Spaces, and less Number of Plants, that cause the Crop to be so large, there being more Pasture for those Plants. Where these Spaces are narrower, and the Rows of equal Thickness, we see the Plants less when grown, and that they make a less Crop; and yet there seems to be room for more Rows, which we fansy might make the Crop larger, not considering that ’tis the Narrowness of those Spaces that causes the Plants and Crop to be less, for want of sufficient Pasture. Thus, fondly increasing the Number of our Rows and Plants, we bring our Crop (unless the Soil be rich) to nothing, by too much over-stocking their Pasture; and, if that Pasture be over-stock’d, the Crop will be diminish’d more than in proportion to that Over-charge; for perhaps ’tis not impossible to prove (if we would be curious), that Plants, by wanting a Fourth Part of their due _Quantum_ of Nourishment, will be diminish’d to half[177] of the Bulk they would have attained to, had they been supply’d with the other Fourth Part. [177] When Plants have not their due Nourishment, they suffer the more by Cold and Drought; so that want of Nourishment diminishing their Growth One-fourth, Cold, or Drought, or both, may diminish it another fourth. I have observ’d ho’d St. Foin to grow more, and increase its Bulk more, in Two Weeks, than unho’d St. Foin in the same Ground (and without any other Difference) hath done in Six Weeks; and the quicker it grows, by being better fed, the sweeter and richer Food it will make for Cattle, whether it be spent green or dry[178].
