ashed and counted from preserved and frozen materials brought in from the summer's Meld trip. Samples of calcareous material (coral, shell, etc.) numbering about 100 and samples of miscellaneous objects such as rope, canvas, wood, grass, coconuts, etc. remain to be done before completing the counting of Bikini and Eniwetok 1948 samples. Eight active calcareous samples, unprepared and weighing approximately 10 gms. each were sent to U.C.L.A. . About 40 frozen Eniwetok fish samples were prepared for U.C.L.A. but not shipped. Additional samples are to be prepared to complete the shipment. A regular schedule for counting samples showing high activity was established forthe purpose of constructing decay curves. Counting was limited to one counter, the IDL counter being at the factory for repair. From the 15th to the end of the month the countirg was stepped up gome by arranging a counting schedule of 18 hours per day. Lauren R.
