manured, broken up, and exposed to atmospheric influences, which increase its fertility. Grass is a fixed crop, chiefly deriving its nourishment from a few inches near the surface, and the only way of refreshing it is by raking or harrowing and topdressing. Hence there are obvious reasons for putting the land into good heart before sowing. Well-rotted stable manure is always beneficial, but fresh manure should be avoided, because of its tendency to make the soil hollow. From twenty to thirty cartloads of manure per acre will probably suffice.
Where artificials are more convenient, 2 cwt. of superphosphate of lime, 1 cwt. of Peruvian guano, and 2 cwt. of bone dust, mixed together, make an excellent dressing. The quantities named are usually sufficient for an acre, and the mixture can be evenly spread and worked into the soil while the preparation of the seed-bed is in progress. Sutton's lawn manure also contains all the constituents essential to the luxuriant growth of fine grasses and clovers. This is a highly concentrated artificial, and as a rule not more than 3 cwt. per acre will be necessary. After the application of the manure, not less than ten days should elapse before sowing the grasses, or some of the seed-germs may be destroyed.
Surface Preparation
A fine friable surface is necessary to ensure favourable conditions for the seed, and in levelling
