GREEN MANURING GRASSES

cially to sow with some of the larger and ranker plants, 

 which may serve to protect them, and to leave the 

 reader, who may be interested in experimenting in this 

 direction, to add to the mixtures according to his judg- 

 ment and pleasure, bearing in mind that when used for 

 the green manuring, neither the coarser plants nor the 

 grasses are allowed to blossom and go to seed, the 

 design being to turn them in before this stage of their 

 growth, in which case the ground is not injured by foul 

 seeds. Suppose, then, we take, as 



GREEN MANURING GRASSES, 



One pound of Bristly Foxtail, 600,000 seeds. 



Wood Hair Grass, 2,000,000 



Tufted Hair Grass, 2,000,000 



Meadow Soft Grass, 1,500,000 

 Perennial Eye Grass, 250,000 



Chess, 150,000 



Millet Grass, 1,200,000 



Melic Grass, 500,000 



Tall Oat Grass, 350,000 



Tickle Grass, 4,000,000

 made himself familiar with the natural history of the 

 grasses, as given in chapter first, and such as are 

 adapted for use on medium soils ; and they may be 

 increased, as already intimated. They are all to be 

 found in the places indicated, their seeds collected and 

 saved for sowing as a top-seed -with grains. One 

 pound of each is stated, for the purpose of indicating 

 the number of seeds it contains. This number cannot, 

 of course, be strictly accurate, because it will always 

 vary a little, according to its cleanliness and freedom 

 from chaff; but it is sufficiently so for practical pur- 

 poses. Only about five million seeds are required for 

 an acre, so that the number of pounds needed to seed
