value as posts or for fencing and makes very poor firewood. 

 On the areas in which it grows it offers some protection to 

 stock. 



The Yellow Pine (Pinus brachyptera) (commonly re- 

 ferred to in much of the literature as P. scopulorum or P. pon- 

 der osa, and sometimes called the Bull pine) is the commonest 

 and most valuable conifer of the State. It grows in the larger 

 mountain areas at elevations of from 6,000 to about 9,000 

 feet, and forms the great bulk of the timbered forests of the 

 State. It is used more extensively for the manufacture of 

 lumber than any other tree within our limits, and makes the 

 best lumber. As a decorative tree it has rarely been used, 

 though it would probably grow at elevations above 6,000 feet. 

 Young seedling trees are common in the forests and where 

 grown singly in the open make very beautiful young trees. 

 If the stand is thick the trees become tall and not so good for 

 decorative purposes. For most formal gardening where coni- 

 fers can be used singly, trees of this species would be as valu- 

 able as the European Scotch Pine. 



The Western White Pine or Limber Pine (Pinus flex- 

 Ms) and its nearly related congener Pinus strobiformis, to 

 which both of the foregoing common names are also applied, 

 occur in the higher mountains, generally above 8,000 feet alti- 

 tude, reaching almost to timber line. They are nowhere very 

 abundant and have no great economic importance, though they 

 are used for lumber along with the other conifers of such re- 

 gions. As decorative trees they are of relatively little value, 

 and would be restricted to the higher levels only. 



The Bristle Cone Pine (Pinus aristata) is a species 

 found only in the high mountains of the northern part of the 

 State at elevations of approximately 10,000 feet or more. 

 Locally in that region it also is called Bull pine, and is also re- 

 ferred to as Foxtail pine or Hickory pine in various places. 

 It is of no economic importance in this State, because of its
