"How can I collect a set of bear tracks?" was the query put to one of the naturalists recently. The process by which liquid plaster is poured into a fresh animal track, allowed to harden, and this cast used as a negative from which to produce a replica of the original was described. The visitor then went on to explain that a friend in Tennesee is planning a rustic cabin for a troop of Boy Scouts, and in the process of construction has conceived the novel idea of impressing the tracks of various Wild animals; bear, deer, raccoon and rabbit into the fresh cement of the sidewalk. Using the negative blocks of plaster sent from Mt. Rainier in place of the actual feet and paws, in connection with a photograph showing the correct spacing of steps the scoutmaster will reproduce the hop, skip, and jump of the rabbit and the heavy tread of the black bear. And so by going outside the door of their cabin the boys will be able to study at first hand the footprints of animals that are roaming the wilderness 3000 miles to the westward.

We were reminded of the now famous collection of footprints of movie stars in the foyer of one of the Hollywood theaters. Doubtless an actress is easily persuaded to register the size of a shapely foot in everlasting concrete, but the print of a wild animal must needs be taken with neither his knowledge or consent.
