great annoyance of the agrlcultor, which, when the ground is not 



or 



hard, may be beft, I believe, drawn out by a deep harrow, 

 Mr. Cook's fcarifier; as a plough turns them over under the foil, as 

 It breaks them, and thus much increafes their number by in a man- 

 ner transplanting them. The teeth of the harrow, or fcarifier, (hould 

 be inclined forwards towards the horfe for the purpofe of lifting up 

 the roots, and that it may not too eafily rife out 'of the foil ; and it 

 fhould be fixed by wedges or fcrew-nuts to the wooden frame for th 



e 



purpofe of occafionally lengthening them to adapt them to different 

 foils, as the roots pierce deeper into lefs tenacious foils than into clayey 



ones. 



Hence it app 



^ 



that a plant of grafs confifls not only of 



tuft 



of leaves furrounding the root, but that the three or four lower joint 



;m, as of a wheat-ftraw, are fo many fucceffive leaf-buds 



of the a 



hich are generated by the caudex of the leaf, which furrounds each 



pi 



precede the flower-bud at the fummit 



d th 



h 



/ith the defign of producing much herbage for cattle, the propagation 

 f new leaves from the root is principally to be attended to; but with 



defign of p 



or winter fodder, the leaf-buds of th 



flem are principally to be attended to. 



For the former of thefe purpofes the ftem of grafs (hould be eaten 

 down as foon as it rifes ; whence more grafs leaves will arife from 



the root: as is well 



wh

buds, which confl

 DO luxuriant. For the fecond purpofe the leaf- 



vn, ba- 



the ftems of grafs, fhould be cut dcf 



feed 



s 



as 



fore the flow^er-flem at the fummit has begun to ripen its 

 at that time the fweet juice lodged in the joint below the flower-ftem 

 becomes expended on the feed ; and the flem becomes converted into 

 flraw rather than into hay. 



From' hence it is readily underftood, why thofe paflures, which are 

 perpetually grazed, are fo much thicker or clofer crowded with grafs 



annually mowed ; and why grafs cu!
