bodies of Trees in a grove ; all the iiourifh- 

 merit being drawn up to the tops of the 

 feveral branches by the leaves which are 

 there expofed to the warm fun and free 

 drying air* w T hereby the branches of Trees 

 expand much. 



And where the lateral branches are very 

 vigorous, fo as to make ftrong (hoots, and 

 attract the nourishment plentifully, there the 

 tree ufually abates in its height : But where 

 the tree prevails in height, as in groves, there 

 commonly its lateral branches are fmalieft, 

 So that we may look upon a tree as a com- 

 plicated Engine which has as many different 

 powers as it has arms and branches, each 

 drawing from their common fountain of 

 life the root : And the whole of each yearly 

 growth of the tree will be proportionable 

 to the fum of their attracting powers, and the 

 quantity of nourishment the root affords 2 

 But this attra&in^ power and nourishment 

 will be more or lefs, according to the differ- 

 ent ages of the tree, and the more or lefs 

 kindly feafons of the year. 



And the proportional growth of their 



lateral and top branches, in relation to each 



other, will much depend on the difference
