which 11 abounds at the elevation of 7,500 or 3,000 feet, or rather onoe 

 abounded, for, as Professor Sargent states, the trees within reach are 

 fast being out awaj tosupplj the mines with timbering. For this pur- 

 its strong and close grained, tongh, and reddish wood is preferred 

 to that of an\ other a\ ailable tree. 



lOHopkylUif the single-leaved Nut Pine, isa most characteristic 

 of the interior basin, mainly of the western and southern part of it, 

 which i! onlj slightly overpasses in Arizona and Southeastern Califor- 

 nia, [tisal m growth,andof only ten to twenty feet in height, 

 yet with trunk sometimes two feet in diameter, and with whin- and soft 

 i. furnishing valuable fuel, and in this region of narrow 

 choice it is much used for making charcoal. The great important 

 the i and still is, in the crop of large and delicately flavored 

 - which it yields, constituting a staple article of food for the Indians 

 of the Great Basin. 



/'" ?, the Pinon or Nut Pine of the Southeastern Rocky 



Mountains, extends from the Arkansas to New Mexico and Arizona, a 

 tree uot larger than the foregoing, also has its importance in its edible 

 Is, and in the value of its wood for fuel. 



i, the White Pine of the Rocky -Mountains, and belonging 

 to th< general section as the Atlantic White Pine, but peculiar in 



its thick cones and good-sized edible seed, inhabits the higher region of 

 the Rocky Mountains from Montana to New. .Mexico and the higher 

 da ranges. What is considered as a Bhort-coned variety of it 

 - the highest tree, commonly reduced to a shrub, on and around 

 alpine summits of the Sierra Nevada throughout all its length, and even 

 northward in the Cascade Ranges to latitude 53°, in British Columbia. 

 In the Rocky Mountain region this tree becomes large enough to be 

 sawn into boards; and its light and sofi w<H>d is the best substitute for 

 the . ne Lumber. 



Pa Do glat [, the Douglas Spruce, the most valuable timber 



of the w( ith the possible exception of the Redwood . is 



hardly one of the second rank iii such of the interior districts as it in- 

 habit.-, lint it is apparently absent from all the ranges west of the 

 rjintas and south of the forty-second parallel until the western slope ot 

 the Sierra Nevada is reached, and is not very abundant in those of Col
