The two firfl Species were brought 

 from Virginia, many Years fince, 

 where they grow in great Plenty, as 

 it is probable they do in moll other 

 Northern Parts of America. The 

 firft Sort feldom advances in Pleight ; 

 but the Branches trail upon the 

 Ground, and fend forth Roots, by 

 which they propagate in great Plen- 

 ty- 



The fccond Sort will grow up- 

 right, and make a Shrub about four 

 or five Feet high, but rarely exceeds 

 that in this Country. This may be 

 propagated by Layers, and is equal- 

 ly as hardy as the former. 



The third Sort here mention'd 

 grows erect to the Height of five or 

 iix Feet : the Leaves of this Kind are 

 much fmaller, than thofe of the 

 common Poifon-oak ; but the Bran- 

 ches of this are flexible, fo that it 

 will never make a Shrub of any great 

 Height or Strength. 



The fourth Sort was found in 

 Maryland, from whence the Seeds 

 were fent to England. This grows 

 more upright than the former, and 

 by the Appearance of the young 

 Plants, feems to be a Shrub of much 

 larger Growth. 



The fifth Sort is a Native of Vir- 

 ginia, from whence I received the 

 Seeds : this puts out Roots from the 

 Branches, which fallen themfelves 

 to the Stems of Trees, or the Joints 

 of Walls, by which the Branches 

 are fupported. 



The fixth Sort is a low Shrub, 

 feldom rifmg more than five Feet 

 high. All the Sorts of Toxicoden- 

 dron difter in Sex, the Male never 

 producing any Fruit, having fmali 

 herbaceous Flowers, without any 

 Embryoes. 



Thefe Plants are prefervM by the 

 Curious in Botany, for the fake of 

 Variety ; but as there is little Beauty 

 in them, they are not much cultiva- 



ted in England. The Wood of thefe 

 Trees, when burnt, emits a noxious 

 Fume, which will fuffbcate Animals 

 when they are Ihut up in a Room 

 where it is burnt : an Inftance of 

 this is mention'd in the Pbilofopbical 

 Tranfacliom by Dr. William Sfoerard, 

 which was communicated to him in 

 a Letter from New-England by Mr. 

 Moore, in which he mentions fome 

 People who had cut fome of this 

 Wood for Fuel, which they were 

 burning, and in a fhort time they 

 loft the Ufc of their Limbs, and be- 

 came flupid ; fo that if a Neighbour 

 had not accidentally open'd the 

 Door, and feen them in that Con- 

 dition, it is generally believ'd they 

 would foon have perifh'd. This 

 mould caution People from making 

 ufe of this Wood. 



All thefe Sorts are hardy Plants, 

 which will thrive in the open Air in 

 this Country ; but they love a moift 

 Soil, and mould be planted under 

 Trees in WildernelTes, where they 

 will thriye very well, and endure the 

 Cold better than where they have a 

 more open Expofure. They may 

 be propagated by Seeds, or from 

 Suckers, which fome of the Sorts 

 fend forth in plenty, or by laying 

 down the Branches of thofe Sorts 

 which do not put forth Suckers ; 

 which in one Seafon will be fufli- 

 ciently rooted to tranfplant ; when 

 they mould be planted where they 

 are defignM to remain. The bell 

 Time to remove thefe Shrubs is in 

 March, becaufe then there will be 

 no Danger of their fuftering by 

 Froft. 



When a Perfon is poifoned by 

 handling this Wood, in a few Hours 

 he feels an itching Pain, which pro- 

 vokes a Scratching, which is follow- 

 ed by an Inflammation and Swelling. 

 Sometimes a' Perfon has had his Legs 

 pcifon'd, which have run with Wa- 

 ter.
