and ponderosa pines, while on the drier ground a little farther east 

 the pines increase and the tirs decrease or disappear. Most of the 

 larger trees on the south and west slopes have been cut for lumber. A 

 stump near IVIcOloud Sawmill measures, at G feet above the ground, 8 

 feet in diameter. 



Incense C!^dar {Libocednis decurrens), — The incense cedar occurs 

 in greater or less abundance in all parts of the ponderosa forest, on 

 both dry and wet ground, and from the bottom of the valley at fcJisson

up to the edge of the Shasta firs at Wagon Camp. But it is common- 

 est near the cool east base of the Scott Mountains. lu moist places 

 the trees often grow in groups, but in the dry forest they are usually 

 scattered at intervals among the pines. On Shasta the bark of the 

 cedars is generally smooth and free from scales, except on the very 

 youngest trees. In the more humid area between Scott JMountains and 

 the coast the scaly bark persists for many years, so that the trunks of 

 middle-aged trees look very different from those of corresponding size 

 m the dry interior.
