SOME GENERAL PRINCIPLES 22, 



else; and when sown to enrich the land, it is, 

 in all, or nearly all, instances, sown without ad- 

 mixture. 



When sown primarily to produce seed, there are 

 no good reasons why timothy and probably some 

 other grasses may not be sown with medium red and 

 mammoth clover, when pasture is wanted from the 

 land in the season or seasons immediately following 

 the production of seed. 



The presence of these grasses may not seriously 

 retard the growth of the clover plants until after 

 they have produced seed, and subsequently they will 

 grow more assertively and produce pasture as the 

 clover fails. Moreover, should they mature any seed 

 at the same time that the clover seeds mature, they 

 may usually be separated in the winnowing process, 

 owing to a difference in the size of the seeds. But 

 timothy should not be sown with alsike clover that is 

 being grown for seed, since the seeds of these are so 

 nearly alike in size that they cannot be separated. 



\\'^hen hay is wanted, the practice is very com- 

 mon of sowing timothy along with the medium red, 

 mammoth and alsike varieties of clover. Timothy 

 grows well with each of these; supports them to 

 some extent when likely to lodge; matures at the 

 same time as the mammoth and alsike clovers; 

 comes on more assertively as the clovers begin to 

 fail, thus prolonging the period of cropping or pas- 

 turing; and feeds upon the roots of the clovers in 

 their decay. 



Next to timothy, redtop is probably the most use- 

 fial grass to sow with these clovers, and may in
