form of Yellow Pine is abundant on the north slopes of 

 the Chirricahua and the Huachuca Mountains. The 

 new Broad-leaved Pine inhabits the Santa Rita Moun- 

 tains, and the new Apache Pine is found in the wild, 

 Apache-infested, Chirricachua Mountains, while the 

 northern form of the Mexican White Pine is found along 

 the streams in all these scattered mountains. Large sec- 

 tions of the eastern part of Arizona are covered with fine 

 orchards of the soft-shelled, delicious New Mexican 

 Pinon, while the southern portion is supplied with an 

 overflow of the hard-shelled Mexican Pinon. Several 

 Junipers, including the thick, oak-barked species, abound, 

 while on several mountains occur the naked, red-limbed 

 Arizona Cypress, and in a low, wet canon of the Chirrica- 

 hua Mountains is the beautiful Bonita variety, with 

 never a sign of a naked branch. 



COLORADO. 



The western portion of this State being composed of 

 a section of the lofty Rocky Mountains, is consequently 

 rich in forest coverings. At altitudes of 10,000 feet and 

 more, Engelmann's Spruce holds complete sway. Above 

 the spruce belts are the Rocky Mountain White Phie ? 

 the White-bark Pine, the Sub-Alpine Fir, and the rare 

 Alpine Hemlock. At lower stations are found the prim 

 stratified Colorado White Fir, and in certain high 

 "parks, 1 ' the thin-barked, slim Tamarack Pine takes 

 complete possession. Below, and largely covering the 

 cool ravines, is the Rocky Mountain variety of Yellow 

 Pine; the ridges and mesas contain extensive orchards of 

 tfie New Mexican Pinon, fringed and interspersed with 

 masses of the round-headed ever-present commoners of 

 the West, the small-berried Junipers.
