SHRUBS AND TREES. l8l 



Spring, if they are properly ftruck, cut them 

 from the llools, or mother plants, and plant 

 them in rows in the nurfery, to acquire proper 

 growth for their feveral purpofcs in planting. 



That, for confiderablc propagation by lay- 

 ers, as in the public nurferies, flools are 

 formed, by having young trees, &c. cut down 

 near the bottom, in order that they may pro- 

 duce proper fupplies of lower fhoots and 

 branches near the ground, convenient for lay- 

 ing. 



Or fometimes, in making layers in parti- 

 cular trees in which the branches are high 

 from the ground, pots of earth are placed 

 upon feme kind of elevated Hand, convenient 

 to receive the layers, and to remain till 

 rooted. 



As obferved of the cuttings, the pine and 

 fir kinds, cedars, and others of that nature^ 

 do not fucceed well by laying. 



By grafting, many trees and fhrubs are 

 raifed ; but it is more particularly proper for 

 many of the capital fruit-trees, and occa- 

 fionally in particular varieties of other trees 

 and Ihrubs, that either do not come the fame 

 from feed, or that do not fucceed, or cannot 

 be conveniently raifed, by the other methods 

 of propagation. However, as before cbferved, 

 many of our beft: fruit-trees are always raifed 

 principally by grafting, fuch as apples, pears, 

 plums, cherries, medlars, &c. by which their 

 different VHrieties are with certainty continued, 

 by engrafting (hoots of the refpedive forts into 

 proper Hocks 5 and which method of propa-
