about a Fortnight or three Weeks 

 after planting they will begin to 

 moo , when the Glaffes muft be 

 raifed on one Side every Day, to ad- 

 mit frefli Air to thePiancs ; and they 

 mull be frequently re'refhed with 

 Water ; but it mould not be given 

 them in large Quantities, until the 

 Plants are grown pretty ftrong, left 

 thereby you rot the Roots. When 

 the Vines have fpread fo far as to 

 reach the Sides of the Glaffes, the 

 Glaffes muft be railed with three 

 Bricks, to allow room for the Vines 

 to fpread ; but the Glades mould not 

 be taken quite away from the Plants 

 until June, when the Plants will be 

 paft Danger of Injury from the Cold. 

 As thefeVine 1 fpi ead, fo the Ground 

 about them Ihould be looiened and 

 Taifed, that they may more eafily 

 itrike their Roots into it; and in dry 

 Weather the Vines ihould be water- 

 ed all over, three or four times a 

 Week ; which greatly ftrengthen the 

 Plants, and caule the Roots which 

 are formed at each Joint of the 

 Vines, to grow large and fair : they 

 muft alio be conftantiy kept clear 

 from Weeds, which, if fufrered to 

 grow amor.gft the Plants, will over- 

 bear and greatly weaken or deftroy 

 them. Thefe Roots muft remain un- 

 citturbed till Autumn, when the firft 

 Approach of Froft will pinch the 

 tender Leaves of the Vines, at which 

 time you muft immediately take up 

 the Roots ; for if the Froft mould 

 reach them, it will intirely deftroy 

 them. Thefe Roots may be kept in 

 dry Sand, in a warm Place, for Ufe 

 in the Winter ; and a few of the 

 foundeft muft be preferved to make 

 a frefh Plantation in the Spring. 



The Jalap, whofe Root has been 

 long ufed in Medicine in Europe, is 

 a Native of the Province of Halapa, 

 about t.wo Days Journey from La 

 Vira Cruz in the Spmttijb IV eft -Indies, 



from whence the Root is fent in 

 great Quantities every Year to Eu- 

 rope ; but it is of late that the Plant 

 has been known to the Europeans y 

 for Dr. "Toumefort, upon the Infor- 

 mation of Father Plumier, has deli- 

 vered it as one of the Species of the 

 Marvel of Peru, and conftituted the 

 Genus under the Title of Jalapaz 

 but my late learned Friend Dr. WtL 

 Ham Houfioun, who was at La Vera 

 Cruz two or three times, procured 

 fome Plants from Halapa, by his In- 

 tercft with an ingenious Spaniard^ 

 which he carried to Jamaica, and' 

 planted there ; by which he was in-* 

 formed truly that it was one Species} 

 of Con-vo'-vu/us ,and accordingly gaveS 

 it the Name I have here mentioned, 

 it under. 



This, and moft of the other Sortl 

 of Convolvulus here mentioned, were£ 

 found in feveral Parts of America, byj 

 the fore-mentioned Dr.HGvfioun,\v\uA 

 fent the Seeds of them into E*g 

 land, where they have been cuP' 

 vated ; but as moft of them a 

 abiding Plants, and require a war 

 Stove to preferve them in Winte 

 few of them have been maintain 

 here : for they fpread and ramble f< 

 far, that few Stoves now built a 

 tall enough to contain them ; and 

 they are intermix'd with otherPlant 

 they will twift themfelves roun 

 whatever Plants grow near them,a~ 

 will foon overbear and deftroy the 

 if not timely prevented. 



All thefe Sorts of Convolvulus a 

 propagated by Seeds, which lhoul 

 be fown in a moderate Hot-bed ear! 

 in the Spring : thofe Sorts whi 

 have large Seeds, mould be fov 

 very thin, and buried deeper in t" 

 Earth, than thofe which have fin 

 Seeds : in about a Fortnight aft 

 they are fown, the Plants will begi 

 to appear above-ground, when th 

 daffes of the Hot-bed Ihould \
