 cording to her irresistible propensity ; or thrown together by 

 Man judging a priori what mixture of seed will afibrd the 

 most valuable produce. 



The separate values of our most common indigenous 

 grasses being ascertained, Ave are enabled to form a pretty 

 good estimate of the value of the compound formed by tlieiv 

 mixture ; for it is not likely that an individual grass will carry 

 into that compound, any qualities which it did not possess 

 in its solitary state. 



I shall commence with the mixtures formed by Nature, 

 and examine what are the grasses Avith which, by her own 

 effort, she generally clothes our surface ; or in other virords, 

 forms a sole upon ground she shortly before had found 

 naked. 



Should these obtrusive grasses appear to be of valuable 

 kinds, Man has no occasion to interfere. Nature does his 

 whole businesslierself ; and when he shall have taken fYoni 

 his ground as many crops as he thinks it will bear, he has 

 only to leave it to Nature, and she will restore a verdant 

 and productive surface. 



Should, on the other hand, the grasses most ready to ob- 

 trude themselves, and outstrip the others in taking posses- 

 sion of our vacant surface, appear to be of inferior quality 

 and scanty produce, when taken individually, the agricul- 

 turist, if he be wise, will interfere, and in his turn outstrip
