ranges of California it occa-sionally goes as low as 1,100 feet, owing to heavier precipitation andan abundance of atmospheric moisture; but the bulk of it is foundbetween 3,000 and 5,000 feet. In the mountains of northern Cali-fornia it grows between 2,500 and 6,000 feet, occasionally reachingas low as 1,000 feet where conditions are particularly favorable. Itattains its best growth, however, between 3,000 and 0,000 feet. Inthe southern Sierras it is seldom found below 3,500 feet, and extendsup to 7,000 or 7,500 feet, doing best between 4,000 and 6,800 feet.On the east slope, in extreme eastern California and westernNevada, its range is limited to the Warner Mountains and thenorthern and central Sierras, where it is confined between the 5,000*md 7,000 foot elevations. In the coast ranges of southern Californiaand northern Mexico it grows still higher, the extreme aridity fixingits lower limit at about 4,000 feet and forcing it up as high as 9,000or 9,500 feet at its southern limits.

Similarly a rise isnoticeable from west to east, the limit in the coast ranges being 1,100and 5,000 feet, on the west slope of the Sierras 3,000 and 7,000 feet,and in western Nevada 5,800 and 7,000 feet.
