SLawn. 109 



Sometimes, on very steep grades, it becomes necessary to 

 fasten the turfs by means of pegs driven through them into 

 the ground. Such places, which are liable to dry up very 

 quickly, should be thoroughly watered occasionally, until 

 the grass is fully established. 



If all edges have been made in the above manner, we 

 may proceed to sow the remaining parts of the lawn. It is 

 imperative that the soil .should be perfectly firm, with an 

 even surface. It must have been thoroughly worked pre- 

 viously, but if it is spaded immediately before sowing, suc- 

 cess is doubly certain, for then it will retain sufficient mois- 

 ture until the grass has commenced to grow nicely. The 

 sowing should take place on a calm day, as, if the weather 

 is windy, the smallest and lightest seeds will be blown in 

 all directions. 



Some kinds of grasses grow best in shade, others in 

 open places ; a few will do well on sandy and sterile soil, 

 while the majority are found in rich fields and meadows. 

 The varieties commonly used for lawns are : English rye 

 grass (Lolium perenne and Lolium perenne tenuum) ; the 

 Kentucky blue or meadow grass ( Poapratensis), the smaller 

 meadow grass ( Poa trivialis), wood meadow grass (Poa ne- 

 moral/is), timothy (Phleum pratense), tufted hair-grass (Air a 

 ccespitosa), the crested grass (Gynosyrus cristatus), the sweet- 

 smelling spring grass (Anthoxanthum odoratum), and or- 

 chard grass (Dactylis glomemta), all growing in rich and 

 fertile soil. The red-top (Agrostis vulgar is), the hard fes- 

 cue (Festuca duri'uscula), the sheep-grass (Pestuca ovina), 

 and the bent-grass (Agrostis stolonifera), do well on light 

 and gravelly soil. Besides these the white clover (Trifoliun
