At this particular stage in the development of this course, the problems that could be made are so numerous and the possible development of processes so extensive, that it seems worth while to call attention to some of these problems and developments.

Fig. 73. Crumb tray and scraper.

The crumb-tray and scraper shown in Fig. 73, are problems supplementary to the round plate, the. same tools and processes being used. The metal is cut to shape, the edge lapped over, the design painted on and etched, and the depression beaten down over the edge of the wooden block, and planished and finished in the same way as the plate. The only difference is in the method of planishing the bottom of the tray and scraper; the straight front edge of the bottom must be planished first, crossing from one side to the other in regular even rows, planishing the deepest part of the depression last. The reason for this difference is that if the front edge is hammered last, it will stretch and swell upward and will not lie flat, thereby making it unsuitable for the use for which it is intended, which is after all the final test of any piece of arts and crafts work.
