On the high ridges, among the timber-line Pinus albicatilis, these beds of green cover the pale gray lavarocks, and in the dark forests of Shasta fir they form the only con-spicuous surface vegetation.

Except at its extreme lower limit, it is usually mixed withbuck-brusli (Ceanothns relnfinus). Seen from a distance, the extensive areas of manzanita on thi* lowerslopes of Shasta are very deceptive. They look like meadows of greengrass, but to cross them is in most cases impossible, owing to the den-sity of the growth and rigidity of the branches. For this reason theyform secure retreats for black bears, deer, wild-cats and other anim
