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-
