The bark of the young trees is grayer and quite spongy. The wood is brittle and wide grained. The needles tough, unusually long, being from eight to twelve inches in length and in fascicles of five. They are dark grayish green, clustered in heavy looking bunches at the end of thick, knotty branches. The cones are triangularly oval, about four to five and one half inches in length, strongly attached to the branch by short, thick stems. They ripen in the early fall of the third year but persist upon the tree for four or five years. Cones of all ages of growth hang upon the tree at the same time. The seeds are dark brown with yellowish streaks and are ranked with the Digger and Big Cone pine, the Parry and One- leaf Pinon in food value. The seeds often remain within the cone several years after it has fallen to the ground. TheTorrey pine,in order to counteract excessively adverse conditions, are pro- lific bearers. The cones are dark brown with an upward turning spike on the end of each scale. The scales do not readily release the seeds while on the trees but wait for the winds to send them rolling down to the pockets of earth. Unless the seeds are washed into crevasses of the earth that are filled with mineral soil, they are not apt to ger- minate. So the tree spreads slowly, but now that this tract of land is under the care and direct supervision of a city forester, a new and hopeful growth is gaining a footing. This pine is thought to be short lived, barely reaching to a hundred years of age, as far as can be determined. Yet the strange featiure of this island of pines is that there are no dead stumps to be seen and no scars in the ground from which they.
