GREEN MANURING. 379 



Plant ago Janccolnfa proportionally disappeared. 



In the words of Mr. Lawes: " We learn from those results 

 that good pasture grasses can never thrive upon a i)oor soil ; an; I 

 if a soil does not contain in itself the elements of fertility they 

 must be added from external sources. T may add that if the 

 pasture of a rich soil deteriorates from bad treatment the good 

 grasses do not die out, but only retire from the contest to wait 

 for better times. Under invigorating treatment it will be found 

 that the good grasses soon reassert their supremacy." 



"The general result, comparing the produce by the dilTerent 

 manures in one and the same season, seems to be, that the more 

 the produce is graTuinaceous the more it goes to ilower aiul seed, 

 and the more it is ripeiu^l, the higher will be the percentage of 

 dry substance in the hay. Under the same circumstances, the 

 higher will be the i)ercentage of woody fiber and the lower will 

 be that oi the nitrogenous compounds aiul of the mineral matter. 

 On the other hand, in a large proportion of the non-gramina- 

 ceous herbage the reverse of these things is true." 



In a summary of this subject, M. T. Masters, in Phvif lAfe, 

 says : '* Circumstances are never exactly twice alike ; a condition 

 of absolute equilibrium is never attained. The nearest approach 

 to it is in the case of the unmanured plats aiul of the plats very 

 highly manured, but even these M'ere inlluenced by very slight 

 climatic changes. The Italancein all cases was easily disturbed." 



Oreeii Mailiirill^. — Most of i\\\^ jjaragraph is from a lecture 

 by my colleague. Dr. W. C. Kcdzic. A complete nuinure is 

 found in fresh vegetable matter turiunl under the surface of the 

 soil. It is often convenient to adoi)t this practice on arable 

 fields which are remote from the barn yard where stock are fed 

 in winter. The late Cieorge Gcddes, of Xew York, adopted this 

 plan quite extensively, and believed he found it as cheap as any. 

 It is often convenient to throw in a growth of something betAveen 

 two other valuable crops. For example, after a crop is removed
