The Engelmann spruce forest here is an exceptionally fine one, and the geologist and I discussed it and trees in general. Some of the Indian tribes of the Rockies have traditions of a "Big Fire" about four centuries ago. There is some evidence of a general fire over the Rockies about the time that the Indian's tradition places it, but in this forest there were no indications that there had ever been a fire. Trees were in all stages of growth and decay. Humus was deep. Here I found a stump of a Douglas spruce that was eleven feet high and about nine feet in diameter. It was so decayed that I could not decipher the rings of growth. This tree probably required at least a thousand years to reach maturity, and many years must have elapsed for its wood to come to the present state of decay. Over this stump was spread the limbs of a live tree that was four hundred years of age. Trees have tongues, and in this forest I interviewed many patriarchs, had stories from saplings, examined the mouldy, musty records of many a family tree, and dug up some buried history. The geologist wanted in story form a synopsis of what the records said and what the trees told me, so I gave him this account:-- "We climbed in here some time after the retreat of the last Ice King and found aspen and lodge-pole pine in possession. These trees fought us for several generations, but we finally drove them out. For ages the Engelmann spruce family has had undisputed possession of this slope. We stand amid three generations of mouldering ancestors, and beneath these is the sacred mould of older generations still. [Illustration: A GRASS-PLOT AMONG ENGELMANN SPRUCE]
