This pine gains its name from its sugary exudation, sought by the native tribes, which forms hard white crystallized nodules on the upper side of fire or ax wounds in the wood. This flow contains resin, is manna-like, has cathartic properties, and is as sweet as cane-sugar. The seeds are edible. Although very small they are more valued by the native tribes than the large seeds of the Digger Pine on account of their better flavor. In former days, when it came October, the Indians went to the high mountains about their valleys to gather the cones. They camped on the ridges where the sugar pines grow and celebrated their sylvan journey by tree-climbing contests among the men. In these latter days, being possessed of the white man's ax, they find it more convenient to cut the tree down. It is undoubtedly the most remarkable of all pines, viewed either from the standpoint of its economic value or sylvan interest. It is the largest of pine trees, considered whether as to weight or girth, and more than any other tree gives beauty and distinction to the Sierran forest.--_Jepson_.
The long cones found in abundance about Tahoe Tavern are those of the sugar pine.
_Yellow Pine and Jeffrey Pine_. These are practically one and the same, though the latter is generally regarded as a variety and the former the type. Mr. Leiberg says:
The two forms differ chiefly in the size of the cones, in the tint and odor of the foliage, and in the color and thickness of the bark, differences which are insufficient to constitute specific characters. The most conspicuous of the above differences is that in the size of the cones, which may seemingly hold good if only a few hundred trees are examined. But when one comes to deal with thousands of individuals the distinction vanishes. It is common to find trees of the Jeffrey type as to foliage and bark that bear the big cones, and the characteristic smaller cones of the typical yellow pine, both at the same time and on the same individual, while old cones strewn about on the ground indicate that in some seasons trees of the Jeffrey type produce only small-sized cones. The odor and the color of leaves and bark are more or less dependent on soil conditions and the inherent vitality of the individual tree, and the same characters are found in specimens belonging to the yellow and Jeffrey pine. It is noticeable that the big-cone variety preferably grows at considerable elevation and on rocky sterile ground, while the typical form of the yellow pine prevails throughout the lower regions and on tracts with a more generous soil.
