136 HOW TO GROW GOOD CLOVER. 



Here, then, we have a large proportion of burnet, 

 surely much more than could be accounted for from 

 the number of capsules, at least we will hope so ; but 

 when we consider that the capsule of the sainfoin is 

 single-seeded and that of the burnet is two-seeded, we 

 may readily conceive how each capsule of the latter may 

 at least grow a single seed, but the best sample of the 

 former could hardly be expected to all come up. Now, 

 as we have as many as 64,000 capsules of burnet 

 in a bushel of sainfoin seed, that x 2 = 128,000 

 seeds, and when we consider that the burnet grows 

 so much faster than the sainfoin, we have two ele- 

 ments for the success of the former, namely, the cer- 

 tainty of getting its crop, and the equal certainty of 

 smothering out a large proportional of what may 

 germinate of the seeds of the sainfoin. 



This matter would not be of such importance if the 

 burnet was equal in point of feeding properties, but 

 it is not so, for whatever quality be in the smaller 

 and more succulent P. smiguisorba form, the P. muri- 

 catum is, on the contrary, hard and woody, and almost 

 useless.
