Ohfervations and Concluftons drawn from the pre^ 

 ceding Premtfes, 

 iji. As the growth of Elm bears proportion to 

 the extent of ground allotted for its roots to range 

 in J thofe who would propagate large timber, mufl 

 never plant too clofe. 



^dly. That though branchy elms are the quickeft 

 growers*, they are not the moft profitable to the 

 planter ; for fuch timber is little fought after, and 

 one branch only being accepted by the merchant 

 as timber, the reft all go with the top, which re- 

 duces the contents exceedingly. 



^dly. That as the value of this timber confifts 

 more in the length and bulk of the fhaft, than in 



* That branchy trees are the quickeft growers, I believe to be 

 invariably the cafe, and may be thus accounted for : the ftp im- 

 bibed by the roots, is a compound of aqueous and nutritious mat- 

 ter ; the quicker it is in its paflage, the greater is the demand upon 

 the roots, which extend themfelves accordingly in fearch of frefli 

 fupplies } the branches follow their direftion, and ftill increafe the 

 demand j and the more branches a tree has, and the nearer they 

 are to the ground, the fooner the fap perfpires off its aqueous par- 

 ticles, depofiting the nutritious ones by the way. Wherefore the 

 timber is more amply fed by an accelerated current of fap, than 

 by a tardy one, confequently branchy timber increafes more in 

 proportion, than tliat which is clean fhafted, where the fap is longer 

 in its progrefs, finding no outlet till it reaches the top.
