then covered with the bell glass, which should 

 be pressed pretty tiglit so as perfectly to ex- 

 clude the outward air.* If there are several 

 cuttings of the same sort, they may be all put 

 in one pot, unless they happen to be very large, 

 or curious sorts ; but I would advise to have 

 each species kept in a separate one, on account 

 of the difference in time that some of them re- 

 quire to strike roots ; and also, that any scarce, 

 or valuable kind should be put only one in a 

 small pot, as they then are not liable to be in- 

 jured so much by damp ; neither do they re- 

 quire to go through the precarious operation of 

 separate potting, so soon after being struck. 



Should it be requisite to have a considerable 

 quantity of cuttings made at the same time-, it 

 would be proper to have a one-light box, with 

 close glasses, (such as are used for raising 



* Here a curious circumstance offers itself to the philo- 

 sophic eye, viz. that the cutting should be more certain of 

 growing, by being enclosed within a glass, like the receiver 

 of an air pump : which proves, the necessity it is under of 

 living (as I may say) on itself until rooted: the atmosphe- 

 ric air being prevented by the glass from exhaling any of 

 its juices, all its powers are forced downward to produce 

 those roots, and they will soon prove their existence by 

 producing young leaves and branches.
