ALSIKE CLOVER 217 



this may be done by not grazing alter the hay has 

 been harvested until other heads have formed and 

 ripened. A limited number of these will thus form 

 after the crop has been mown for hay. If the crop 

 has been cut for seed, many heads will in any event 

 be left upon the ground. The same result will fol- 

 low when grazing the crop, if grazing is made to 

 cease at the right time, and for a period long enough 

 to allow a considerable number of heads to mature. 

 This method of renewal will not prove a complete 

 success on all soils, as, for instance, on those very 

 stiff and very light. 



Natural meadows that lie low may be changed in 

 whole or in part into alsike meadows or pastures in 

 some of the States, as has been previously intimated, 

 by sowing seed on them in the early spring. (See 

 page 202. ) In some instances such change has been 

 effected by sowing seed but once, and at the rate 

 of from 3 to 4 pounds per acre. In other instances 

 it has been found preferable to sow a less quantity 

 for two successive seasons, lest one of the two should 

 prove adverse to successful growth in the plants. 

 But on some slough soils a stand cannot be se- 

 cured by this method of sowing, more especially 

 when they are composed of raw peat.
