^ i H E ufual method of propagating the common whire^ 

 Thorn, with which I fliall begin, is fo univerfaliy known,, 

 as to- render it unnecelTary to be related here ; and the more fo,, 

 as it is very faulty, and will admit of as many improvements in 

 its culture, as any plant hitherto mentioned in this Treatife. 

 Thefe plants, from the feed-bed, are commonly fold at fo low a 

 price, that the mofl fkilful nurferyman cannot afford good 

 Thorns for double the ufual rates. From this caufe, which is 

 ftiled felf-defence, they are generally fown extravagantly thick ; 

 and nothing is more common, than to hear nurferymen exulting 

 in their knowledge and fliccefs, by having more plants on the fame 

 quantity of ground than tlieir neighbours, unmindful that they 

 are boafting of their fhame, that the plants are good for nothing, 

 and that an experienced judicious planter would not take a pre- 

 fent of them for his own ufe. But as the nobleft and mod ufe- 

 ful improvements in agriculture, in a great meafure, depend on 

 the belt methods of cultivating this common hardy plant, I ihall 

 treat it with more difcindlion than it has hitherto been, and feed 

 it with better fare. The praflice I Iliall here direct I do not 

 mean to infinuate to common nurferymen for fale, as the reafons 

 above given make their compliance impracticable, till one or other 

 bolder than the reft, or rather private gentlemen, lead the vs^ay,,
