Your lawn has been well broken up, well sowed, except that you omitted a portion of white clover, " but is now filled 'with switch-grass," etc. You must either mow it very frequently, or pasture it with sheep, and hand-weed the worst portions. The difficulty in all new lawns, for some years, is, that the weeds being more rampant in their growth than the finer grasses, get ahead, and overpower them. By keeping the entire growth of weeds and grass constantly down, either by close mowing, or by feeding down with sheep, the fine grasses get a better chance of sun and air, and eventually they subdue their enemies. Sheep feed closer than the scythe can cut; but, in July and August, care must be taken that they do not nip too close, or the roots of the fine grasses would suffer. White clover is indispensable to a good bottom sod; grass alone for a lawn does not get thick enough unless mowed occasionally, say once a month, when it is not what is properly a lawn, but a well-kept field. P. P. should, in the spring, fresh harrow his lawn, sow six or eight pounds of Dutch clover to the acre, roll, and either mow frequently, say every ten days, or inclose with hurdles and keep sheep on it for one, two, or three years, carefully fencing them from the trees, until he is satisfied with it; then remove the hurdles, and restore it to its original object Don't expect a lawn, any more than a hedge in one season.

In England, the bottom is formed by moss; here, where it is too warm and dry for moss, we must use the next best substitute, white clover.
