Before leaving, the visitor ... was handed a copy of the last Canadian Forestry Association Journal, and given a brief description of the nation-building work of this society, together with an addressed card inviting him to join. Finally he inspected a cabinet filled with highly finished samples of Canadian woods, and the last thing his eye rested upon and which impressed itself on his memory as he left the car, was this bold fire warning: “A tree will make a million matches; a match will burn a million trees.” ARRANGEMENT OF CAR FOR DEMONSTRATIONS When an audience is to be gathered in a car to witness a demonstration or hear an illustrated talk, the first requirement is that the speaker can be easily heard and each process plainly seen by everyone in the car. The second is that the audience shall be comfortably seated if the demonstration is to last longer than fifteen or twenty minutes. This is about the limit of time that an audience will stand without becoming restless. The illustration on the opposite page shows an interior especially constructed for cooking demonstrations, or rather for brief object lessons, as a feature of the Pennsylvania Food Conservation Train. The demonstrator stands on a platform raised a foot higher than the floor. A counter extending the length of the car curves out at the center to leave a space for the platform and small kitchen. The maximum space for a standing audience is provided, and all are within easy range of the speaker’s voice and near enough to see the objects in her hand. The space below the counter is lined with cupboards. A similar arrangement might be suitable for any demonstration or illustrated talk in which few objects are used, provided the counter is raised high enough to show the entire process. If the extension of the counter along the sides were left out the space could be used to seat an audience around a raised central platform.
