INCENSE CEDAR.

in figure 1 and its peculiar habit of buttressing is illustrated in 

 figure 2. 



In computing age and volume from stump measurements it is 

 necessary, because of the extreme butt taper of the species, to reduce 

 stump measurements to the relative diameters at some fixed point 

 for the sake of comparison. Table 11, prepared for this purpose, 

 gives in terms of inches and tenths of inches the taper from various 

 stump heights to diameter breasthigh, or 4^ feet above the ground, 

 the standard point of measurement.

 height; basis, 101 trees {Plumas National Forest, 1912).

ROOT SYSTEM. 



Incense cedar is decidedly windfirm, and few cases of uprooted 

 trees are to be found. In general, the root system is fairly wide 

 spreading and composed of a number of large, stocky, many-branched 

 laterals with numerous short, small; descending offshoots, forming 

 a compact, intricately tangled mass immediately around the base of 

 the tree. The tree does not develop a taproot beyond the early stages, 

 although a pronounced taproot is characteristic of the seedlings, as 

 in most conifers. Incense cedar stands root pruning better than most 

 species and develops numerous laterals, which makes it an easy tree 

 to handle in the nursery. 



FOLIAGE AND BRANCHING. 



The foliage of incense cedar is evergreen and consists of small, 

 pointed, scalelike leaves, which adhere closely to the slender branch-
