This path, as all projectionists know, is the path between the negative carbon tip and the core of the positive carbon. It is evident, therefore, that due to the electronic bombardment and the slower volatilization of the shell, a saucer-shaped crater is the product of the faster volatilization of the core which results from this bombardment. "W7TIILE I am at the task of setting down the foregoing few words for my good friend, Mr. James J. Finn, I should like to include a few words on a topic which I consider is becoming increasingly important as various changes occur in the projection field. This topic has to do with projectionist training and subsequent licensing. Projectionists at Fault Standards have been set up in this industry for the production and distribution of motion pictures, for the manufacture of essential equipment, the control of raw stock and a multitude of other activities. Yet there have never been any standards for the training of projectionists— and as for the licensing situation, there can be no doubt that projectionist licensing at its best is a disgrace, particularly to the projectionist craft and in general to the industry. The present method of licensing is at the root of practically all the trouble now being experienced by organized groups of projectionists.
