good plants. The tops should be taken off those 

 Intended fur stock plants, and rooted. The stumps 

 will then throw up one or more leaders according 

 to the strength or size of the trees so cut. These 

 may be taken off and rooted, when the old plants 

 will repeat the process. 



Soil. All the species thrive in good, friable, well- 

 drained loam. Sand and leaf mould may be added 

 tW those grown in pots. If planted out in the 

 IT.- I* of the cool conservatory or winter garden 

 -"! turfy loam should be used to replace the 

 natural soil, if in anyway unsuitable. Imbricate 

 will thrive for a time in almost any soil, but if the 

 subsoil is sand or gravel the trees deteriorate as 

 they get old. To sustain large trees the soil must 

 be deep, rich, and we! 1 drained.

ARAUJIA. 



Description. - Twining evergreen shrubs (ord 

 Asolepiadete). The genus includes the plants 

 known in gardens under the name of Physianthus 

 and Schubertia, the former having salver-shaped 

 and the latter funnel-shaped flowers. A. sericifera 

 makes a very handsome climber for training up the 

 rafters in greenhouses and conservatories where a 

 temperature of 45 to 50 is maintained during the 

 winter months. In warm districts it will thrive 

 out of doors on a wall. The others require stove 

 heat, and to be trained in the same way. Flowers 

 white or purple. 



Propagation. By seeds in heat during spring 

 Short and firm side shoots, taken off in summer 

 and inserted in sandy soil and plunged in gentle 

 bottom heat, or put in a propagating case, root 

 freely. 



Soil. Fibrous, mellow loam and peat in equal 

 proportion, with plenty of sand to render it porous 

 Borders must be thoroughly well drained.

 Physianthus auricomis, and Schubertia grandiflora) 

 Flowers sweet scented.

 Physianthus albens). 



ARBORETUM. 



A collection of hardy trees and shrubs planted 

 for decoration or instruction ; also the ground 

 occupied by such a collection. 



As a rule, the object most directly in view when 

 making an arboretum is effect. Spring, summer, 

 and autumn tints of flowers and foliage have all to 

 be considered, and the planting must be arranged 

 accordingly. Arrangement according to botanical 

 classification is not advisable, for although this 

 has its advantages it is much better left to the 

 botanic garden. When scientifically constructed, 

 and the trees properly attended to as they grow 

 up, the arboretum is one of the chief sources of 

 attraction in the pleasure grounds, and the fine 

 collection of trees at the Duke of Northumberland's 

 seat at Syon House, Brentford, and Captain Hoi- 

 ford's at his Gloucestershire home, Westonbirt, 

 Tetbury, show what can be accomplished in this 

 direction. 



ARBOR 



Hardy evergreens, suitable for growing as indi- 

 vidual specimens or for hedges. They are raised 

 from seeds sown in spring, and from cuttings. 

 They will succeed in almost any fairly good soil, 

 and luxuriate in a strong loam. For species gee 

 THUYA. Perhaps the best known is the American 

 (Thuya occidentalis). 



ARBOUR. 



A summerhouse, generally with open sides, or 

 with lattice-work covered by climbing plants of 

 various kinds. Nooks of this character are amongst 

 the most pleasurable resorts in gardens, particularly 

 when placed so that they command a view of some 

 part of the flower beds or borders. As they are for 

 summer use only they should be cool, and shaded 

 from the sun. Arbours composed of rustic, un- 

 barked wood are amongst the best, as the climbers 

 take kindly to them. Iron structures are more 

 permanent, and also much more expensive.
