EVERY teacher of general chemistry frequently has cause during the year to wonder if there might be some relationship between a dingy, disorganized locker and the befuddled mind of the student who unlocked it. Surely, the loss of time at the beginning of a period entailed by required washing of stained glassware and by hunting for the pieces of equipment that never seem to be twice in the same place in the locker, is worth considering. The author and his staff of instructors have, during the past two years, tried to help the beginning student save time Ey enforcing a plan of arrangement of locker equipment largely because the adoption of the "kit system" caused severe crowding of the 15" X 18' X 8" drawer locker. The student upon "checking in" receives a plan (Figure 1) which is selfexplanatory, and during the first periods is assisted in arranging his equipment. In this the student is further assisted by having on display in the laboratory a model locker fully equipped according to the plan. The student who welcomes this assistance needs no further urging in this or any other phase of laboratory technic, but he is too often in the minority. To further impress upon the student the instructors' insistence on orderliness in locker arrangement as well as orderliness in his thought processes, the inspection of lockers is made equivalent to one question in laboratory quizzes. The grade resulting from the inspection, although small in its e5ect on his record, has seemed to give the careless student a real reason for keeping his house in order. The results seem to justify this brief
