134 EXPERIMENTAL FARMS 



9-10 EDWARD VII., A. 1910 



11. Pinus resinosa. — Red pine (Canada). Height 40 to 60 feet. Not unlike the 

 Austrian pine when young, but becoming less stiff in form as it becomes larger. The 

 leaves are also much softer than those of the Austrian pine. 



12. Pinus sylvestris. — Scotch pine (Europe). Height 40 to 60 feet. A very rapid 

 growing pine with bluish green leaves. It is not so shapely as some of the other 

 species, but grows well in nearly all kinds of drained soils. 



13. Pinus Strohus. — Wliite pine (Canada). Height 50 to Y5 feet. The white 

 pine is better known as a timber tree in Canada than as an ornamental tree, but when 

 it branches from near the ground, and has sufficient space to develop symmetrically, 

 it becomes one of the most graceful evergreens grown. The leaves, which preserve 

 their colour well in winter, are a very lively green. 



14. Picea alba. — White spruce (Canada). Height 30 to 50 feet. A very beautiful 

 native species with glaucous green leaves and rather rigid branches, but making a fine 

 ornamental tree. 



15. Picea alcochiana. — Alcock's spruce (Japan). Height 40 to 60 feet. This ia 

 a very ornamental Japanese species, and quite distinct from all others. The dark 

 green of the upper part of the leaves, and the bluish silvery green of the lower surface, 

 make it very attractive. 



16. Picea excelsa. — Norway spruce (Europe). Height 50 to 75 feet. The Norway 

 spruce is one of the most popular evergreens planted, being a very rapid grower, of 

 graceful form, and doing well on a great variety of soils. 



17. Picea pungens glauca. — Rocky mountain blue spruce (Western United States). 

 Height 40 to 60 feet. A very beautiful species with steely blue coloured leaves. One 

 of the most ornamental trees. It is a slow grower and takes some years before it at- 

 tains much height. As this tree varies in colour from green to blue in individual 

 specimens, in procuring young trees the blue variety should be ordered. 



18. Pseudotsuga Douglasii. — Douglas fir (British Columbia). Height 50 to 75 

 feet. The Douglas fir is a very majestic and handsome tree, with foliage dark green 

 above and silvery beneath. The seed or young trees should be obtained from as far 

 north as possible, or high up on the mountains, as otherwise it is not likely to prove 

 hardy 



19. Taxus cuspidaia. — Japanese yew (Japan). The Japanese yew has proved 

 perfectly hardy so far at Ottawa, and is a decided acquisition to the list of desirable 

 evergreens. It is of more upright habit than the Canadian yew and has attractive 

 dark green foliage. 



20. Thuya occidentalis aurea Douglasii. — Douglas' golden arbor-vitse (United 

 States). This is a very beautiful form with bright golden coloured foliage and up- 

 right habit. 



21. Thuya occidentalis compacta. — Compact arbor-vitse (United States). A dwarf 

 compact variety with bright green foliage. 



22. Thuya occidentalis Ellwangeriana. — Ellwanger's arbor-vitse (United States). 

 This is a fine, compact, dwarf, vigorous variety with slender leaves and branches. 



23. Thuya occidentalis Hoveii. — Hovey's arbor-vitae (United States). This is one 

 of the finest and most desirable varieties. The leaves are bright green and the branches 

 flat and parallel, giving the shrub a very remarkable and attractive appearance. 



24. Thuya occidentalis pyramidalis. — Pyramidal arbor-vitae (United States). The 

 pyramidal arbor-vitae is a very compact upright grower, and its columnar form makes 

 it one of the most conspicuous objects on the grounds.
