Thus the bark of a growing aspen car- ries a record of all that tree's vicissitudes for those who can read. Bear claw-marks, frost- crack, woodpecker borings, insect ravages, horn thrusts from Wapiti, Squirrel gnawingsonthemere expansions and sutures of growth, are a'l there, in plain and legible sight (Plates !). Deep marks such as claw-wounds may even get stronger as years go by. I know of a singular case—a. Blackbear climbed in aspen some twenty years before I saw it—there was the record plainly to be seen, but the claw-marks, at first deep pits, had filled up ns level black scars, and at length became ever-lengtheninr; bumps, till now each is pro- longed into black claw-like warts i J inches long (see Fig, 243). In addition to the claw- and teeth-marks, it is common to see the bear-tree more or less plastered with mud in which is Bear hair. This was left by some Bear rubbing his back and marking his height after he had been wallowing in the mud. Some observers think that the registers are used only in the running season, but I have reason to believe that in a less degree they serve the year Fic. >43 —Quakinf upen, with Bear claw-Kan grown out into bumps li inches Inug.
