Aquilegia, or Columbine (nat. ord. 



E&mmculaceae). 



A pretty herbaceous perennial of which 

 many beautiful hybrid varieties have been 

 recently introduced. Seeds of these can 

 be obtained of any nurserymen, and should 

 be sown in March in any ordinary garden 

 soil. 



Araucaria (nat. ord. Pinace). 



The best -known variety of the trees 

 which bear this name is the Araucaria 

 isnbricata, or Chili pine, sometimes called 



ARUCARIA KXCEI.SA. 



the Monkey Puzzle, because it is said to be 

 the only tree the monkey cannot climb, on 

 account of the sharp, stiff leaves anned 

 with thorns at the point which cover the 

 long, drooping boughs like scales or tiles, 



each overlapping the one in advance of it. 

 It can be grown from seed and cuttings of 

 young wood that has ripened, planted in 

 light but rich loam and covered by a hand- 

 glass. To ensure rooting the cuttings 

 should be carefully shaded. A young 

 plant of Araucaria excelsa, or the Norfolk 

 Island Pine in a pot, is shown in the 

 accompanying illustration.

 Arboretum. 



The pinetum (which see) is a piece of 

 ground set apart for the reception of 

 cone-bearing trees and pines, all of 

 which possess a certain degree of simi- 

 larity. An arboretum is simply an ex- 

 tension of this idea, and in the ground 

 thus called are placed all known hardy 

 trees, and not trees of a single family only. 

 It may be defined as a place set apart for a 

 collection of trees and shrubs, containing 

 only one or two plants of each kind, and 

 arranged according to system. It may be 

 of any extent ; but to render it useful, each 

 tree and shrub should be named. In 

 planting an arboretum, the principles laid 

 down for the pinetum in reference to 

 distance, grouping, &c., will be applicable. 



Arboretum, Trees for. 



The following trees may be planted in 

 the arboretum, either singly or in orna- 

 mental groups, at the back of shrubberies, 

 or in parks or pleasure grounds.
