AND COKSEETATOET. 195 



It is remarked above that to do complete justice to the 

 orange and the lemon they must be planted out in a good 

 border in a well managed conservatory. We are tempted to add 

 that to do perfect justice to them they should be grown in 

 houses devoted to them alone, and we may as well add further 

 that an amateur desirous of a special and very choice hobby in 

 the way of plant growing, could hardly find a more attractive 

 subject than the orange when provided with a proper house 

 and cultivated with earnestness. As a winter garden, a well 

 managed orange-house would be quite unique, and the very 

 fact that it would have to be kept cool and airy all the summer 

 would render it an agreeable place of resort even then, when 

 covered gardens are least cared about. Por general purposes 

 the common orange is the best for the amateur cultivator, but 

 in an orange-house we should of course require a collection of 

 varieties, and the St. IMichael's and Tangerine would probably

All the insect plagues that ever were known appear to have 

 a liking for the orange. The black deposit we frequently find 

 on the leaves is a sure sign that thrips or scale have secured a 

 lodgment. To get rid of this sooty pollution syringe the trees 

 well and then wipe the leaves on both sides with a dry sponge, 

 which must be frequently washed and squeezed dry as the 

 work proceeds. It is a tedious business, but it must be done. 

 If scale and meally bug obtain a decided lodgment it will be 

 necessary to sponge the trees with warm strong soapsuds. 

 If green fly appears smoking must be resorted to. While, 

 however, you are removing the vermin, you must promote the 

 health of the trees by good management, for in almost every 

 case the appearance of any insects upon them may be re-
