Lawn is a surface of turf in the vicinity of the house, requiring to be kept smooth by the regular application of the roller and scythe. When first constructed, after the ground has been dug over as level as may be, it must be rolled, the hollows filled up, and this repeated until a level surface of earth is obtained. It must then be slightly pointed over with a fork, and the turf laid, or the grass seed sown. See Turfing. If seed be employed, the following is a good selection, and in the requisite proportions for an acre. The best season for sowing is during moist weather in March.

On 1 acre of new lawn, sow the following grass seeds: Festuca durius-cula, 4 1/2 lbs.; Arena flavescens, 11/2 lb.; Lollium perenne, 30 lbs.; Poa nemoralis, 3 lbs.; P. sempervivens, 2 lbs.; P. tri-vialis, 21/2 lbs.; Trifolium repens, 11 lbs., and T. minus, 3 lbs. This is a sufficient quantity to cover the ground closely in a short time.

In very dry weather all lawns should be watered, and if a little guano and muriate of lime be dissolved in the water it will keep the surface gently moist even in dry weather.

A good kind of grass for improving a lawn, is Crested Dogstail; it may be sown in March. Bush-harrow the lawn in order to stir up the soil a little for the seed, which should be sown broadcast when the ground is damp, passing a garden roller over it when the ground becomes sufficiently dry. - Gard.
