line when compared with those trees, is fully compensated, in 

 our estimation, by its supeib and heavy masses of foliage, -which 

 catch and throw off the broad lights and shadows in tlie finest 

 manner. When the Black Walnut stands alone, or on a deep, 

 fertile soil, it becomes a truly majestic tree; and its lower 

 branches often sweep the ground in a pleasing curve, which gives 

 additional beauty to its whole expression. It is admirably 

 adapted to extensive lawns, parks and plantations, where there 

 is no want of room for the attainment of its full size and fair 

 proportions. Its rapid growth and umbrageous foliage also rec- 

 ommend it for public streets and avenues." 



The flowers expand in May, but the fruit is not ripe until Oc- 

 tober. Young trees may be transplanted from the woods, or 

 they may be grown readily from the seed. 



27. Carya alba, of Nuttall. — Shag-Bark Hichory. 



The Hickories were first separated from the Walnut, and a 

 new genius established to re_eive them by Mr. Nuttall. For- 

 merly they were all included in the old genus Juglans ; but the 

 least examination the of outer covering of the seeds or nuts will 

 show the propriety of the new nomenclature. In the Walnuts 

 it is undivided and remains attached to the nut, while in the 

 Hickories it is divided into four valves and falls away when ripe. 



The Shag-bark Hickory ma}'- be readily distinguished from 

 the other Wisconsin species by the loose, scaly exterior bark. 

 It is one of our most valuable trees ; especially for fuel, for which 

 purpose it is not exceeded in value by any other. As the re- 

 sult of careful experiment, it is found to yield twice as much 

 heat per cord as the Eed Maple, White Birch, Butternut, and 

 Pine ; and one half more than the Sugar Maple, Beech, Red 

 Oak, Pin Oak, and Elm. The great strength and elasticity of 

 the wood make it desirable for a great variety of purposes. 



The Hickory is also a very fine ornamental tree, that should 

 be much more often seen about our houses and public grounds. 

 The difficulty of transplanting it, is probably the principal rea- 

 son why it is not more often used for such purposes. It grows 

 very rapidly from the seed, and one could very soon obtain a
