104 HOW TO GROW GOOD GRASSES. 



out with a knife, taking care to drop a pinch of salt 

 on the crowns that we leave behind ; and then, if 

 we use a little fine lawn-grass seed to the vacant 

 places, and well roll after the process, we shall 

 certainly keep them under. This should he done 

 in spring, and not in autumn, as we shall then he 

 more certain of success, upon the principle before 

 explained. 



If, despite all we do, a few crowns still send up 

 shoots, our mowing must always be frequent enough 

 to prevent their seeding; and as in the height of 

 summer, seeding, in the case of all three of the plants, 

 will take place in a few days, such neglect as our own 

 lawn once got when we were away for a month's 

 vacation, in not being mowed sufficiently often, may 

 take years to remedy. 



3. The Mixture of Grasses is secured by constant 

 mowing and rolling, by which means anything like a 

 wild method of grass-growth is avoided. When, 

 however, a lawn is left for a long time without such 

 careful treatment, some of the grasses are sure to 

 stool out and grow bunchy. In this case, the quickest 

 way of putting the matter to rights will be to remove 

 the offending tufts, and introduce new turf, taking 

 care to keep the whole in order by the scythe and 

 the roller. 



Talking, however, of these implements of lawn- 

 culture reminds one to remark that with some the 

 scythe and roller are almost discarded, at least in 

 summer. Our own lawn is rolled with an iron roller 

 during the winter and early spring ; but when mowing 

 begins, we prefer the new lawm-mowing machines. 

 We have now used one of Samuelson's for four years, 

 and it has not cost us a single sixpence for repairs ; a
