Substitute fuels tested. Conducting an experiment to determine whether engine wear is increased by the use of fuel substitutes, Emmet L. Reed of Washington, D.C. makes an identification mark on the cylinder of an automobile engine. The rate of the mark's disappearance will determine the degree of wear. This is part of the "ersatz" fuel experiments which are being conducted at the U.S. Bureau of Standards
