with spreading branches and long two-ranked leaves of a 

 pale glaucous color. This is a perfectly hardy and very 

 ornamental tree of a pyramidal habit, and one of the best 

 specimens for small lawns where there is place for a few 

 trees only. The great silver fir (A. grandis) is hardly less 

 beautiful, but less glaucous. A. nobilis is another fine tree 

 of an almost columnar habit with stout spreading branches 

 and glaucous leaves. Nordmann's silver fir (A. Nord- 

 manniana) is, however, the most common and popular of 

 all these trees. It is of a narrow pyramidal habit, with 

 short but ample branches and long leaves, of a dark, shining 

 green color on the upper side, and slightly silvery beneath. 

 This is an excellent lawn tree and comparatively easy to 

 obtain. 



False Hemlock, Pseudotsuga Douglasii. A tree almost 

 as common and popular as the Nordmann fir, of a less formal 

 habit, with slender elegant branches, and two-ranked, light 

 green leaves. Not hardy in the extreme North. 



Hemlock, Tsuga. These are well-known trees in rocky 

 woods on hillsides and ravines, often seen among deciduous 

 trees, forming little groups and scattered masses among birch 

 and oak. They have slender, feathery branches and an ele- 

 gant habit, with dark green or silvery foliage. Many 

 varieties of the common hemlock (T. canadensis) are of a 

 broad and bushy habit in a young state, and almost rival 

 the Deodar cedar in beauty. T. Hookeriana is a species 

 with more glaucous leaves than the common hemlock, a very 

 graceful tree, but probably not hardy in the extreme North. 

 The hemlocks are useful for hedges, for screen planting, and 

 as an undergrowth in woods and copses. Small groups of
