and thrive better there than that before, as we evidently see by Corn sowen on Land where hardly Grass would have grown, what a Crop you reap; but these are but Annuals: that which raises the greatest advantage to the Husbandman, is what annu∣ally yields its increase without a renovation of expence in Ploughing and sowing; as we finde in the Clover-grass or great Trefoyl, St. Foyn or Holy-Hay, La Lucern, Spurrey-seed, Trefoyl, None-such, &c. whereof apart.
This Grass hath born the name, and is esteemed the most prin∣cipal of Grass, both for the great Improvement it brings by its prodigious Burthen, and by the excellencie of the Grass or Hay for Food for Cattle, and is much sowen and used in Flan∣ders and in Holland, Presidents to the whole world for good Husbandry.
In Brabant they speak of keeping four Cows Winter and Sum∣mer on an Acre, some cut and laid up for Fodder, others cut and eaten green: here in England they say an Acre hath kept four Coach-horses and more all Summer long; but if it kept but two Cows, it is advantage enough upon such Lands as never kept one. You may mow the first Crop in the midst or end of May, and lay that up for Hay; if it grow not too strong, it will be exceeding good and rich, and feed any thing: then reserve the next for Seed, which may yield four Bushels upon an Acre, each Bushel being worth three or four pound a Bushel, which will amount to the reputed value of ten or twelve pounds per Acre; and after that Crop also it may be fed. It hath also this Property, that after the growing of the Clover-grass three or four years, it will so frame the Earth, that it will be very fit for Corn again, which will prove a very great Advantage, and then again for Clover. Thus far Mr. Blith. Others say it will last five years, and then also yield three or four years together rich Crops of Wheat, and after that a Crop of Oats.
In the Annotations upon Mr. Hartlibs Legacie, we finde several Computations of the great Advantage hath been made by sowing Clover-grass, as that a parcel of Ground, a little above two Acres, the second year, did yield in May two Load of Hay worth five pounds: the next Crop for Seed was ripe in August, and yielded three very great Loads worth nine pounds that year; the Seed was 300 l. which with the Hay was valued at thirty pounds, be∣sides the after-Pasture. Another President is, that on four Acres there grew twelve Loads of Hay at twice mowing, and twenty Bushels of Seed; one Load of the Hay mown in May being worth two Load of the best of other Hay, and the After-pasture three times better than any other; the four Acres yielded in one year fourscore pound. Another, that six Acres of Clover did maintain for half a year thirteen Cows, ten Oxen, three Horses, and twen∣ty six Hogs; which was valued at forty pound, besides the Win∣ter-Herbage.
The aforesaid Presidents and Valuations seem prodigious, un∣less a rich, light Land, warm and dry, be sown therewith, in which
