Poplar : the Shoots are very Jlender 

 and weak : the Iuli, or Katkins, are 

 produced at remote Difances from the 

 Fruits on the fame Tree : the Fruit 

 becomes a little fquamofe Cone : the 

 Seeds are winged : and the Tree cajls 

 its outer Rind every Tear. 



We have but one Species of this 

 Tree, which is common in Eng- 

 land ; <viz. 



Betula. Dod. The Birch-tree. 

 This Tree is propagated by Suck- 

 ers taken from the Roots of old 

 Trees, which may be tranfplanted 

 either in Oclober" or February ; but 

 Oclober is to be preferred ; for, if 

 i the Spring fhould prove dry, thofe 

 planted in February will many of 

 them'fail : it delights in a poor Soil, 

 I and will grow in either moift fpringy 

 I Soils, or in ftony or gravelly Manlies 

 or Bogs : when the young Trees 

 I have been planted two Years, you 

 I fhould (if defigned for Under- wood) 

 leut them down within fix Inches of 

 I the Surface, which will caufe them 

 I to (hoot out ftrong and vigorous 

 I Branches ; but if they are defign- 

 I ed for large Trees, it will be much 

 I better to let them ftand three Years 

 I before you head them down ; and 



■ when you do it, cut them within 



■ three Inches of the Ground, that 

 their Stems may be ftrait and hand- 



fome : but you m -ft obferve, when 



;they begin to put out, whether they 

 produce more than one Shoot ; which 



[if they do, you muft rub off all but 

 the ftrongeit and molt convenient 



i Shoot, which muft be trained up for 



la Stem. 



The Timber of this Tree, though 

 I iccounted the worft of all others, yet 

 \ s not without its various Ufes : the 

 • I Turners often ufe it, to make Chairs, 

 lisV. and the Huflbandmen, for make- 

 I ng Ox-yokes ; it is alfo plnnted for 

 i rlop-poles, Hoops, &e. but in Places 

 K vithin twenty Miles of London, it is

kept often cut to make Brooms, and 

 turns to great Account. 



There are three or four other Sorts 

 of this Tree growing in the North- 

 ern Parts of Germany, Sweden, and 

 Lapland, which are all of them ra- 

 ther Shrubs than Trees, the talleft of 

 them feldom rifing above ten Feet 

 high, the others about three or four 

 Feet ; and, being of little Ufe, I mail 

 not enumerate them. 



There is alfo a Birch -tree, which 

 has been raifed in the Gardens late- 

 ly, whofe Seeds came from America: 

 the Leaves of this Sort are larger 

 than thofe of the common Birch- 

 tree; but this may be only from the 

 Plant's being young and vigorous ; 

 fo cannot be pronounced different, 

 by its prefent Appearance.

The Characters are ; 



It hath a compound Flower, for the
