Where a piece of land is long kept in lawn, it must have an occasional top-dressing every two or three years, if the soil is rich, or every season, if it is poor. As early as possible in the spring is the best time to apply such a top-dressing, which may be a compost of any decayed vegetable or animal matter-heavier and more abounding with marsh mud, etc., just in proportion to the natural lightness of the soil. Indeed almost every season the lawn should be looked over, all weeds taken out, and any poor or impoverished spots plentifully top-dressed, and, if necessary, sprinkled with a little fresh seed. Wood ashes, either fresh or leached, is also one of the most efficient fertilizers of a lawn.
We can already, especially in the finer places on the Hudson, and about Boston, boast of many finely kept lawns, and we hope every day, as the better class of country residences increases, to see this indispensable feature in tasteful grounds becoming better understood and more universal.
