planted. They are covered with the 

 hand-glass till thoroughly established. By 

 pursuing this course all check on the 

 vigorous growth of the plant is avoided, 

 while the tendency to increased luxuriance, 

 so necessary in plants whose leaves or 

 flowers are eaten, is encouraged. 



Watering. After planting out, copious 

 watering should be given in the mornings 

 in dull, cloudy weather, or in the evenings 

 after bright sunshine. 



Treatment of, during Winter. On the 

 approach of winter, the plants in flower 

 may be taken up with as much earth at 

 their roots as possible, and planted, or 

 rather laid in by the roots, on their sides, 

 in a light sandy soil, in some warm, 

 sheltered place, where the frost can be 

 excluded. In such a shed or frame they 

 may be kept fresh and in condition for 

 many weeks. Another way of protecting 

 and preserving them is to dig pits in the 

 ground, and to plant the cauliflowers in 

 them, coveiing them with frames of long 

 wheat straw, tied together in small bundles, 

 and giving them air in fine weather. 



Ceano'thus (nat. ord. Rhamna'ceae). 



An extremely handsome, free-flowering 

 genus of highly ornamental half-hardy 

 shrubs, suitable either for conservatory 

 decoration, or for covering fronts of villas, 

 walls, or trellis-work in warm situations ; 

 they succeed best in peat and loam. Some 

 are hardy deciduous shrubs, and others 

 evergreen shrubs, suitable only for green- 

 houses and hothouses. Of the hardy de- 

 ciduous plants, Ceanothus Americanus and 

 C. azureus are, perhaps, the best known. 



which is large enough to admit it, and 

 where it can have shelter from the wind. 

 In its original habitat it attains 120 feet in 

 height, and is frequently 40 feet in cir- 

 cumference. It is distinguished from all 

 others by its handsome pyramidal form 

 and beautiful glaucous green foliage. In 

 speaking of its excellence as a timber tree, 

 Mr. Loudon says, " The wood is very 

 compact and resinous, and has a fragrant 

 smell, remarkably fine and of close grain, 

 capable of receiving a very high polish 

 so much so, indeed, that a table formed 

 of a section of a trunk, 4 feet in diameter, 

 sent by Dr. Wallich to Mr. Lambert, has 

 been compared to a slab of brown agate." 

 Df. Royle says that the wood is particularly 

 durable, and is much used in the construc- 

 tion of Himalayan houses. In Cashmere 

 it is used for both public and private 

 buildings, and likewise for biidges and 

 boats. Strips of it are also burnt as 

 candles.

 The seed is first sown in the same way and 

 at the same time as that of ordinary celery.
