ROCK-WORK, PLANTS FOR. 427 



ROLLER, GARDEN. 



the brickyards and clinkers from the smith's 

 furnaces are not to be rejected. The sea- 

 shore also, all along the coast, affords 

 plenty of material out of which a little 

 taste and good judgment will soon arrange 

 something both agreeable to the eye and 

 useful as a bed for many different classes of 

 plants. On the piece of rock-work which 

 has just been described may be planted 

 almost every variety of hardy or half-hardy 

 creepers lophospermums, Maurandya 

 canarienstSy the different sorts of peri- 

 winkle, &c., &c. ; while lower down, 

 between the stones, cistuses, saxifrages, 

 and sedums may be grown. The wild 

 sedums of our different counties form most 

 interesting collections when placed by 

 themselves in a separate piece of rock- 

 work ; and so also do the wild ferns. (See 

 also Root-work.} 



Rock-work, Plants Suitable for. 



All the smaller plants named elsewhere 

 in lists, and many of the larger ones, are 

 suitable for rock-work ; but at the risk 

 of repetition it will be useful to append 

 a list here exhibiting in a collected form

 suitable for this purpose, shortening it by 

 omitting heights, colours of flowers, &c.

Roller, Garden. 



The roller is a machine that is absolutely 

 indispensable in every garden, whether 

 large or small, being required both for the 

 lawn and for garden paths, especially when 

 gravelled. Ordinary garden rollers are of 

 two kinds, known as single cylinder and 

 double cylinder rollers, so called because 

 the cylinder of the former is one and the 

 same piece of metal from side to side, 

 whereas in the latter it is in two equal and 

 similar parts. There is a third kind of 

 roller, known as the water-ballast roller, 

 which is so constructed that the interior 

 can be filled with water, thus considerably 

 increasing its weight when necessary, and 

 giving the owner the advantage of using it 

 either as a light or heavy instrument at 

 pleasure. The best rollers of all kinds are
