of which have been propagated under special names, such 

 as compacta, fastigiata, glauca, and pendula. It is pecu- 

 liarly a valuable tree for ornamental planting in the West 

 and East. Horticulturally it is classed with the firs, but 

 botanically it is placed between the spruce and hemlock. 



East of the Jakes the balsam fir (Abies balsamea) and 

 such foreign species as A. Nordmanniana and A. Piclita 

 are favorites in park and lawn planting, but they are short- 

 lived at the "West. 



330. Some of the Pines. The pine family has many 

 species in about all parts of the earth. In this connection 

 only a few of the hardiest and handsomest can be referred 

 to. The white pine (Pinus strolus) of Iowa and western 

 Wisconsin is adapted to prairie planting, and it has better 

 form and a denser habit for Eastern planting. As obtained 

 from any point east of the lakes, it fails to endure the dry 

 hot air of the corn-growing belt. 



The red pine (Pinus resinosa) is a favorite for Northern 

 and Western planting. Its form of top and thick clusters 

 of slender, soft, dark-green and long leaves fit it specially 

 for ornamental planting East or West. But the Eastern 

 type is not hardy on the prairies. 



The yellow or bull pine (Pinus ponderosa) as obtained 

 in the Black Hills of South Dakota stands every exposure 

 at the North and West, is quite rapid in growth, with 

 rounded conical top and a bold expression that fits it 

 specially for picturesque parts of the grounds. As obtained 

 from Colorado the tree is more open, and as it attains age 

 it loses its regularity of outline. 



Of the foreign species, Pinus laricio is extremely variable 

 in hardiness as obtained from different parts of Europe. 

 Even the variety known as Austriaca or Austrian pine is 

 variable, as grown from seed, in habit of growth, color of 

 foliage, and hardiness as grown in the West. Its harsh
