will propagate and encreafe by the root, and 

 other different ways, for increafe, if required: 

 though fome being rather biennial, as fnap- 

 dragon, carnations, wall-flowers, flock gilli- 

 fiower, &c. are apt to dwindle off in two or 

 three years ; yet the tRree former may h-i con- 

 tinued perennial in good flowering perfedlion, 

 by propagating them by layers and cuttings 

 annually, efpecially the curious varieties ; and 

 the ftoL^ks feldoni continue in good flrength 

 for flowering longer than two years, or the 

 ihrubby white will fometimes iland feveral 

 years in a dry foil. 



By off-fets of the roots, &c. numerous forts 

 of the foregoing general colle(fiion of peren- 

 nials propagate very abundantly, which are 

 readily difcovered in all the forts as encreafe 

 by that method, by their multiplying lefs or 

 more by young fide-fucker plants, either im- 

 mediately clofe round the main root, or fome 

 proceeding from the crown thereof, or a little 

 above in fome ftocky plants, as in auricula^^ 

 ^*c. and others by roots under ground, fome 

 in creeping rooting fhoots above, and fome 

 by fide-heads: all which, for propagation, 

 may be detached or flipped off with roots,, or 

 near to the bottom, with as much rooty-like 

 part as poffible, that will foon emit fibres 

 when planted; and this work may be per- 

 formed either in Spring, February, March, 

 April, before they fhoot much for fluwering^ 

 or in Autumn, after the flowering is pail, 

 about Auguft, September, October and No- 

 vembef, and in which, fo|ne will confift of
