$ Of this splendid genus botanists enumerate nearly 350 species; but I 

 have never been able to collect together above 320 of them out of British 

 collections, nor do I think there exist more at present in Britain. As plants 

 of ornament they have been greatly overlooked by cultivators, especially con- 

 sidering how hardy they are : for out of the above number above 200 will 

 endure the climate of Britain with the thermometer at 24° Fahr., and many a 

 much greater degree of cold, especially the sheathing-stemmed kinds. In 

 planting the species against a conservative wall, such as that at Chatswortb, 

 there ought to be a ridge of rockwork raised against the wall, composed of old 

 bricks, clinkers, flints, shells, and any curious stones to be found in the neigh- 

 bourhood, the whole to be intermixed with a soil composed of peat earth, 

 white sand^ common garden earth, and lime rubbish,, and thoroughly drained, 

 as much of the success of keeping them alive during the winter will depend 

 upon this ; for, although there is no family of plants luxuriates more when 

 well supplied with water in summer, yet there is great danger with many of 

 them from injudicious watering in winter, more especially when planted out. 

 The same remarks will hold good with the preceding order Crassulaceae, and 

 the following one Cactacese; I would (were it possible in building such a wall) 

 have the spaces allotted for these genera interspersed with cavities formed of 

 rough blocks of lava, madrepores, millepores, and shells of various species, 

 such as Neptune's chair, Strobus gigas, ammonites, &c., into which many of
