longer than they were on their journey, and yet have arrived safe. 

 In the above remarks I hope it will be understood that I disclaim all 

 intention of passing anything off as new or peculiarly my own ; 

 indeed, the knowledge of the universality of the practices there 

 recommended caused me for some time to doubt the propriety of 

 Bending them for publication ; and it was only the recollection of the 

 fact that there was no operation in the art of gardening so perfect 

 as not to admit (to use an expression of the Editor's, in a late 

 number) of "line upon line" being written, that it is impossible for 

 a writer to prevent a reader from including under the same word 

 more ideas than he himself intended, and that in the most unim- 

 portant fact a logical or grammatical error, or misconstruction of a 

 sentence, may often be the means of causing the most important 

 ideas to arise in the minds of others, and thus indirectly bringing to 

 light new facts which directly might have long remained hidden. 



WINDOW GARDENING. 



BT JOHN B. MOLLISON. 



(Continued from page 173.) 



BULBOUS-ROOTED AND ROCK PLANTS. 



iS I said in a former paper, a small rockery under your 

 window in connection with your window-box could be 

 so arranged that rockery, window-box, and creepers 

 would appear to form one harmonious whole. Such a 

 window in the height of the season would have a beau- 

 tiful effect, and be the admiration of every passer-by. Clinkers 

 from a furnace make a nice rockery. A few white pebbles and shells 

 heighten the effect. Raise a mound of soil and build your materials 

 over it as naturally as you can, leaving crevices in which to plant 

 your roots and flowers. I will select a few of the most suitable 

 plants for a rockery. 



Auhrietia. — A lovely little rock plant of many varieties, with 

 green and variegated foliage. Grows in a dense tuft or mass. 



Cerastium tomcntosum. — A silvery foliaged mouse-ear duckweed ; 

 flowers white. 



Arabis. — A hardy class of spring flowering plants suitable for 

 rock-work, of various kinds, green and variegated ; flowers white. 



Echeveria. — This is an excellent class of plants for rock-work. 

 E. pumila, E. //Inma, E. necunda, E. secunda r/lauca, and E. secunda 

 mi t'lllica arc the best for our purpose. 



Armeria, or thrift, the well-known sea daisy ; very pretty rock 

 plant ; flowers red and white, dou'ile. 



Scmpervivum. — Similar to the above. S. Californicum , 8. arach- 

 i',n, and 8. mantanum are tho most suitable. No rockery is 

 complete without Echoverias and Sempervivums.
