At dusk, and with the appearance of a full moon, some of these fish rushed to the surface. The subsequent flip- ping which appeared to extend over at least a square mile of area sounded like the fall of large hailstones on the water. FIG. 4 - ECHO-SOUNDER TRACING OF HERRING SCHOOLS SILVER BAY, SOUTHEASTERN ALASKA, DECEMBER 1952. The fishing captain judged these to be large fish by the sound of the flips. The set was unsuccessful be- cause the fish sounded before the seine could be pursed, and the few small fish caught were obviously not representative of the main body of the school. It was anticipated that herring would be present in this area since it is the major herring spawning ground in Southeastern Alaska. The most impressive showing of herring was in Tongass Narrows which contained an enormous body of herring throughout the winter months. It was reported by residents that the herring had first appeared in the Narrows in the latter part of October. On the John N. Cobb's first visit to this area on November 7, significant soundings were obtain- ed at depths of 40 to 80 feet. On December 6 the John N. Cobb again sounded these waters and obtained the tracings shown __ â ^ in figure 5. On this date thousands of gull
