The firft Sort was formerly in 

 greater Efteem than at prefent in the 

 Englijh Gardens : it was common- 

 ly rais'd in the Nurferies near Lon- 

 don, where their Heads were fheer'd 

 into a conical Figure. But fince that 

 low Tafte of Gardening, in croud- 

 ing vaft Quantities of clipp'd Plants 

 into Gardens, is juftly exploded, 

 thefe Trees do not meet with fo 

 good Reception as formerly ; but 

 notwithftanding this, there may be 

 fome of them planted in Gardens to 

 great Advantage, if they are plac'd 

 in WildemefTes, or Clumps of ever- 

 green Trees, where thefe Ihould be 

 planted with other Sorts which are 

 nearly of the fame Growth : and in 

 fuchPlantations, the dull heavy green 

 Co'our of thefe Leaves will be very 

 ufeful in adding to theLultre of thofe 

 which are of a more livelyGreen,and 

 make a fine Variety. 



The firiped Sort is preferv'd by 

 the Curious in collecting fuch Varie- 

 ties } but tyas little Beauty, 



The China Arbor Vitas hath not 

 been long in Europe : the Cones 

 of this fame Tree were fent from 

 China by fome of the French Mi- 

 flionaries ; and fince this Sort has 

 been introdue'd into the Englijh Gar- 

 dens, it has been greatly propagated 

 by Layers and Cuttings; but the 

 Seeds feldom ripen here. 



The Leaves of this Tree r.re of a 

 beautiful green Colour, and the 

 Branches are well cloath'd with 

 them ; fo that it makes a fine Ap- 

 pearance when intermix'd with other 

 ever-green Trees. . This Tree, al- 

 though a Native of China, is ex- 

 tremely hardy, and will endure the 

 greateft Cold of this Country in the 

 open Air; which renders it more 

 valuable. 



It will grow to the Height 

 of twenty Feet, or upward, and is 

 generally furniftVd with Branches 

 all the Length of the Stem ; fo that 

 it deferves to be rang'd in the firft 

 Clafs of ever-greenTrees for Beauty. 



Thefe Trees may be propagated 

 by laying down their tender Bran- 

 ches in Autumn ; obferving to llit 

 them at a Joint (as is commonly 

 pra&is'd for Carnations), as alfo to 

 water them in dry Weather, and 

 keep them conflantly clear from 

 Weeds. If thefe Things be duly 

 obferv'd, the Layers will be rooted 

 in two Years ; by which time they 

 may be taken off, and tranfplanted 

 into aNurfery inRows three Feet af- 

 under,and the Plants eighteen Inches 

 Diftance in the Rows ; obferving to 

 lay a little Mulch upon the Surface 

 of the Ground about their Roots, to 

 prevent the Wind from drying it; and 

 in dry Weather they ihould be often 

 refrefiVd with Water, until they have 

 taken Root; after which they mult 

 be conftantly kept clear from Weeds, 

 and the Ground dug every Spring 

 between the Rows, that their Roots
