Canadian Blue Grass {Poa pratensis), red top {Agrostis 

 vulgaris), and brown Creeping Bent Grass (Agrostis 

 canina). To this it is generally thought best to add 

 white clover, which thrives on poor soil and in dry- 

 weather better than the other grasses named. It 

 should be said, however, that a grass sod without a 

 mixture of white clover is considered by many, and 

 with good reason, likely to make a more attractive 

 lawn. Some go so far as to recommend the use of one 

 grass only and that the strongest growing kind of a 

 permanent nature like the Kentucky or Canadian 

 Blue Grass, the Canadian to be preferred for sandy soil 

 and comparatively northern regions. It may be said, 

 truly, that no matter how many kinds of grass seed 

 are planted, the Blue Grass is likely sooner or later to 

 almost entirely usurp the place of the others. 



The use of the short-lived grasses like timothy, 

 rye grass, and red clover, although well sidted to go 

 with and succeed for a few years a grain crop, is not 

 suitable for a permanent lawn. 



When the grass seed has been sown and properly 

 rolled, it helps the young recently germinated seed to 

 go safely through the winter to sow some grain (rye 

 in autumn and oats in spring) to make what is called 

 a cover crop. 



It is interesting to note how much the treatment of 

 lawns nearly one hundred years ago resembles that in 

 vogue at present and especially how much even in those 

 days properly prepared muck, or humus, and clay loam 

 as a top dressing was valued.
