.efpecially where the Trees are de- 

 figned to have their Branches fea- 

 thered near the Ground, in which 

 one of the Beauties of thefe Trees 

 con fills. 



The Silver Fir requires a Wronger 

 Land than the Spruce ; for in dry 

 Ground they feldom make much 

 Progrefs ; and many times, after 

 they have arrived to a considerable 

 Size, they are deftroyed by very 

 dry Seafons, where the Soil is mal- 

 low, or too dry. But when they 

 are planted in a proper Soil, they 

 grow to a very large Size, and are 

 very beautiful, having the Under- 

 fide of their Leaves white, and the 

 Upper-fide of a dark-green Colour. 



The Balm of Gilead Fir is ftijl 

 more beautiful ; becaufe the I ranches 

 of the Trees are clofely covered 

 with Leaves on every Side; whereas 

 the Leaves of the Silver Fir are pro- 

 duced only on two Sides of the 

 .Branches,' fo as to appear quite flat 

 like a Comb. JBut the ihort Du- 

 ration of the Balm of Gilead Fir, in 

 molt Places where it has been plant- 

 ed, has greatly difcouraged many 

 Perfons from propagating that Tree. 



The two Sorts of Nexufoundland 

 Spruce Fir are as yet uncommon in 

 the Nurferies ; .but as there has been a 

 good Quantity of theirCones brought 

 into England the two or three laft 

 Years, they will foon become com- 

 mon ; efpecially as there are many 

 Trees of thefe Kinds in England, 

 which begin to produce Cones : but 

 as thefe Trees are of fmali Growth, 

 they are proper for fmall Plantations 

 only, being unfit to mix with the 

 other Sorts of Fir. 



The Scotch Fir, as it is ufually 

 called, being a Pine, I mall refer 

 that to its proper Genus of Pinus ; 

 under which Article all the Sorts of 

 European and American Pines are 

 brought 3 and as their Culture is

To me what different from that of the 

 Fir, the Method of propagating 

 them will be there fully delcnbed. 



The Seeds of all the Sorts of Firs 

 are eafily taken out of their Cones, 

 which are much loofer than the 

 Cones of the Pines ; but as thefe 

 do fo eafily open with Heat, the 

 Seeds generally drop out in hot 

 W eather, and thereby are -poiled 

 from growing foon after. And the 

 Cones of the Silver and Balm of 

 Gilead Firs fall to Pieces on the 

 Trees, if they are not gathered by 

 the Middle or End of Oftoher, where- 

 by all their Seeds will be loft ; fo 

 that whoever is dflurops to fave their 

 Seeds, mould carefully watch the 

 time of their ripening. 



When the Branches, of thefe Trees 

 are cut off, to trim them up to have 

 Stems, it mould be done gradually, 

 never cutting more than two Tier 

 of Branches in one Year ; for if too 

 many Wounds are made at the fame 

 time in thefe refinous Trees, the 

 Turpentine will isTue .out in fuch 

 Quantities as to weaken and check 

 the Growth of them. The beft 

 time for pruning thefe Trees is in 

 September ; at which ti»e they do 

 not abound fo much with Turpen- 

 tine as in the Spring; fo do not 

 bleed much ; and what does £ow 

 out at that Seafon, is feldom more 

 than is neceffary for covering the 

 Wounds, to prevent the Wet and 

 Cold of the fucceeding Winter from 

 penetrating the wounded Parts. 



AEROTANUM, or Southern-

This Plant is better known by 

 its outward Appearance, thrm by 

 any diitinft Characters which can 

 be given of it, agreeing in raoft 

 Parts with the Wormwood, from 

 which it is not eafy to feparare it.
