are much smaller and narrower. Like most of the Poplars, the 

 wood possesses very little value, in the arts of life. The figure 

 represents a leaf ot the natural size. 



49. Populus candicans, of Aiton. — Balmof Gihad Pojjlar. 



This is a favorite ornamental tree, both on account of its beau- 

 ty as a tree, and of the fragrance of its opening buds in the 

 spring, from which it derives its common name. It grows nat- 

 urally along the margin of lakes and rivers in Wisconsin, whence 

 it may be obtained and transplanted to the place it is intended to 

 adorn. It is very hardy, and will continue to grow, under very 

 bad treatment — an essential quality in most cases ! The large 

 leaves give it a coarse appearance to the eye, but cause a very 

 dense shade. It is of rapid growth — and should be more often 

 seen in the streets of our cities and villages.

Order XII. Coxifer.e. — The Pine Family. 



50. Pinus Banhsiana^ of Lamhert. — Gray Scrub Pine. 



The dells of the Wisconsin Eiver is about the extreme south 



ern limit of this arctic species of Pine, 

 which extends thence farther towards 

 the north pole than any other tree. 

 It may be distinguished by the slight- 

 ly curved cones with pointless scales : 

 the short rigid spreading leaves, ar- 

 ranged in pairs in the sheaths, not 

 more than about an inch in length. 

 The tree is only from ten to twenty 

 feet in hight, and is of little or no val- 

 ue, except perhaps for ornamental 

 purposes. 



The figure represents a cone and 

 GBAY SCRUB PINE, the Icavcs, of the natural size.
