DISH-WASHING.
IN ENGINEERING TERMS. A Chicago university student tool-dish-washing as the subject for her M.A. thesis and reduced that thrlcedaily exercise to engineering terms. Three ways of washing dishes was tried. The fastest took 23 minutes to clean up after a typ'cal family of four and comprised 1015 motion-. The slowest took 38 minutes and 1051 motions. Such a savnj of force per cent, might easily mean the d.(Terence between success and bankruptcy in a business.
Yet this is but one part of the. problem (comments the New York * i Hev ald-Tribune”), It seems to have been assumed that iili dishes wash al kc; as if an engineer imagined that workmen could make steel boxes or paper' ones in the same way and with the same effort. The fundamental pri;/- 1 sical thing that happens when dishes are washed is the detachment of foreign particles, many of them sticky or greasy. Some sk'ns wash more easily than others, so do some fabr'cs. Doubtless the same is true of different kinds of surfaces on dishes,
but nobody seems to have studied this with much real attention sin :e some prehistoric genius made the first great dish-washing d.srovery, the one that glazed pots wash more easily than unglazed ones.
