 num ; the wood at the top of the tall trees, therefore, 

 becomes short-jointed and full of blossom buds, and 

 the fruit there situated attains its greatest perfection. 

 Hence, we find pine and fir-trees loaded with the 

 finest cones on the top boughs, the largest acorns 

 grow on the terminal branches of the oak, and the 

 finest mast on the high boughs of the beech and 

 chestnut; so, likewise, apples, pears, cherries, etc., 

 are always best flavored -from the top of the tree 

 But I suppose there are certain limits, beyond which 

 the sap would be so loaded with nutriment, that it 

 could not freely^circulate." 



The sap being determined so powerfully to the 

 extremities of the branches, the most unremitting 

 attention is required upon the part of the vine

But if through negligent management the bearing
