0 A PARTIAL SOLUTION FOR FRESHMAN CHEMISTRY CONGESTION

RALPH E. DUNBAR North Dakota Agriculture College, Fargo, North Dakota

M o w COLLEGIATE institutions today are facing numerous grave, complicated, and necessary adjust- ments due to increased enrollments, not the least of which is the congestion prevalent in many chemical laboratories. The situation has been particularly acute due to the inability of securing adequate teaching help, sufficient supplies of chemicals and apparatus, and to properly provide for and utilize the available laboratory space, desks, and lockers. Many institu- tions have assigned the same lockers and equipment to several students to be used at diierent times during the week with a prcwating of the breakage and fees involved. Such an arrangement frequently leads to dissatisfaction, inefficiency, and wanton waste.

A partial solution to this problem has been provided by constructing a series of individual lockers (Figure 1) which are used by those students that could not nor- mally be cared for by the existing laboratory facilities. A local planing mill has built substantial drawers that measure 10 in. wide, 9 in. deep, and 20 in. long, inside measurements. Each is provided with a sub- stantial "lock" and l'pull." These individual drawers

This is noticeably less freshman chemistry equipment, including a ring stand, than the cost of constructing new buildings or labora- test-tube stand, funnel support, beakers, burner, flasks, tories.
