One autumn a grizzly I was following–to learn his bill-of-fare–tore up a number of dwarfed trees at timber-line while digging out a woodchuck and some chipmunks. A number of the smaller trees I carried home for careful examination. One of these was a black birch with a trunk nine-tenths of an inch in diameter, a height of fifteen inches, and a limb-spread of twenty-two. It had thirty-four annual rings. Another was truly a veteran pine, though his trunk was but six-tenths of an inch in diameter, his height twenty-three inches, and his limb-spread thirty-one. His age was sixty-seven years. A midget that I carried home in my vest pocket was two inches high, had a limb-spread of about four inches, and was twenty-eight years of age.
A limber pine I examined was full of annual rings and experiences. A number of its rings were less than one hundredth of an inch in thickness. At the height of four feet its trunk took on an acute angle and extended nine feet to leeward, then rose vertically for three feet. Its top and limbs merged into a tangled mass about one foot thick, which spread out eight feet horizontally. It was four hundred and nine years old. It grew rapidly during its first thirty-eight years; then followed eighteen years during which it almost ceased growing; after this it grew evenly though slowly.
One day by the sunny and sheltered side of a boulder I found a tiny seed-bearer at an altitude of eleven thousand eight hundred feet. How splendidly unconscious it was of its size and its utterly wild surroundings! This brave pine bore a dainty cone, yet a drinking-glass would have completely housed both the tree and its fruit.
