LAU 



[ 539 ] 



LAY 



Annuals and biennials in common garden 

 soil, by seed in spring ; herbaceotis, by divi- 

 sion, and cuttings at the same time ; shrubby, 

 by cuttings, under a hand light, in sandy soil ; 

 light sandy loam suits them all. The frame 

 and cool greenhouse species merely require the 

 protection of these departments in winter.

LAWN is a surface of turf in the 

 vicinity of the house, requiring to he 

 kept smooth hy 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. For di- 

 rections to lay the turf, see Turfing, and 

 for the proper grasses, if seed is em- 

 ployed, see Grasses. 



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, and the turf green, even in dry 

 weather.

 LAYER. The following excellent com- 

 bination of practice and science is from 

 Dr. Lindley's Theory of Horticulture : 

 A layer is a branch bent into the earth, 

 and half cut through at the bend, 

 the free portion of the wound being 

 called ' a tongue.' It is, in fact, a cutting 



i only partially separated from its parent,
