It now only remains to point out that the constant mowing of lawns, although it only takes away young grass, must in time have the effect of impoverishing the lawn. In such case, the grass will not be of so bright a colour as formerly, and it will become more or less mixed with moss. In this state of matters the grasses die, and different species of agarics live upon the decaying roots. In this condition we find that colour and fertility are restored by a good sprinkling of soot, which usually operates very beneficially for four or five years. After this period a little guano, say one part to three parts of soot, will do better. Another method of restoring fertility is that of an occasional use of house slops, diluted with five parts of water; this showered evenly from a watering-pot, engine, or hydropult, usually has a most beneficial effect. In concluding this subject of “How to Grow Good Grass,” the author would wish to impress upon his readers the important fact, that as our country is so peculiarly adapted for the growth of pasturage, and as this interesting genus of plants furnishes the best kind of herbage, so then the grass tribe is deserving of the most careful study of the home-producer of MEAT, MILK, CHEESE, and BUTTER. * * * * * NOTE.—Belcher’s Plantain Extractor and Turf Inoculator will be found a most efficient implement in extracting plantains, and preparing good turves to fill up the holes. We fancy, too, that it will be found useful in laying down land for permanent pasture by a system of inoculation, but await the result of experiments before stating more positively.—_The Author._ [Illustration: Trifolium repens.
