apart every way, being careful to water them duly, if the 
feafon lhould prove dry, until they have taken root; af¬ 
ter which time thefe plants (as alfo thofe remaining in 
the l'eed-beds) will require no other culture but to keep 
them clear from weeds; which may be eaiily effected, by 
hoeing the ground between the plants now and then in 
dry weather ; and llir'ring the ground will be of great fer- 
vice to the plants. The following autumn thefe plants 
lhould be tranfplanted where they are designed to remain, 
which lhould be in a rich moift foil and a lhady lituation, 
where they will thrive much better than if too much ex- 
pofed to the fun, or in a dry foil, where they will require 
a content fupply of water in dry weather. Thefe plants 
mult not be lefs than two feet ditent every way. When 
they are rooted they require only to be kept clear from 
weeds ; and in the fpring, before they Ihoot, to have the 
ground gently dug between them, fo as not to cut or 
bruife the roots. With this management they will con¬ 
tinue feveral years, and produce feeds in plenty. If you 
would propagate this plant by offsets, the roots lhould be 
parted at Michaelmas, and planted in a lhady fituation, 
at the fame ditence as has been direfted for the feedling 
plants, obferving to water them until they have taken 
root, after which they mult be managed as the feedlings.
