270 Select Plants for Industrial Culture and 



available in 1890, containing each about 2^ Ibs. of this saccharine sub- 

 stance. The small kernels are edible. Jubaea Torallyi ascends the 

 Andes to 8,500 feet. First introduced into the colony of Victoria 

 by the writer of this work. 



Juglans cinerea, Linn.* 



The Butternut-tree of Eastern North-America. Up to 75 feet 

 high ; stem-diameter to 4 feet. Growth of comparative celerity ; 

 admits of transplantation readily. Likes rocky places in rich forests, 

 but is also content with poor soil. Branches widely spreading, thus 

 well adapted for shade lines. Wood lighter in colour than that of 

 the black walnut, durable and free from attacks of insects. It is 

 particularly sought for furniture, panels of coaches, corn-shovels, 

 wooden dishes and similar implements, as it is not heavy nor liable to 

 split. Splendid for select post and rails needing durability ; it is soft 

 and therefore easily worked. This tree with J. nigra endures even 

 the severe frosts of St. Petersburg, where the Caryas can no longer 

 be maintained [Regel]. The kernel of the nut is more oily than that 

 of the ordinary walnut ; taste similar to that of Brazil-nuts. The 

 leaves, bark and husk are of medicinal importance, and so are those 

 of other species. The sap is saccharine [C. Koch]. A form of this 

 or a closely allied species occurs on the Upper Amazon-River 

 [Spruce], and on the mountains of Venezuela [Prof. Ernst ; Dr. 

 Dyer]. 



Juglans cordiformis, Maximowicz. 



Japan. This species approaches in many respects J. Sieboldiana. 



Juglans Mandschurica, Maximowicz. 



Corea and Mandschuria. This Walnut is allied to J. cinerea of 

 North-America. Wood splendid for cabinet-work. The nuts avail- 

 able as well for the table as for oil-factories. 



Juglans Californica, S. Watson. 



From California to New Mexico, along the course of streams in 

 rich moist soil. A handsome symmetrical tree of much utility, 

 attaining a height of 60 feet and a stem-diameter of 3 feet [Dr. 

 Gibbons]. Hardy in Christiania still. 



Juglans nigra, 



Black Walnut-tree. Eastern North-America. Attains a height 

 of 150 feet ; trunk grows to 7 feet in diameter ; fond of rich forest- 

 land. Quicker of growth than the European Walnut-tree, but the 

 wood not so easily worked [Meehan]. Maximum rate of circum- 

 ferential stem-growth in Nebraska 4 feet at 2 feet from the ground 

 in 16 years [Furnas]. The tree will bear fruit after 10 years, giving 

 when of large size, 10 to 15 or even 20 bushels in a season, realizing 

 as much as 4s. per bushel. The tree is hardy still in Christiania.,
