L. Kadstrom 1954 Bugs Lorenz (39) June 9 to Berkeley June 9th. He reports hitting good deluge of rain just Mariposa. I wonder if tree-frogs not involved but very probably B. Lorenz. California June 12 Sentinel Meadow, Yosemite Valley, 4000 ft., Mariposa C., night check made 9:15-10:30 P.M. (D.S.) Earlier about 8:30 P.M. I had found one medium-sized toad by a log campfire circle Camp 19. After- noon rains should bring out toads over most of Valley floor where they exist. Camp 19 is located about 100+ yards S of Merced River along which some breeding ponds may be found. No other toads discovered around the camp. I walked the paths to Sentinel Bridge and the meadow, etc. N along former road crossing meadow. One large adult ♀ (#5b see data sheet) encountered on bridle path 30 yards W of rocky footpath. She so full of insects appears sluggish. Cannot feel egg masses. may or may not be post-breeding ♀. Closed temp. 9.8°C ; air 9.5°C ; 9:37 P.M. (D.S.) Ground wet from afternoon downpour. No other toads found tonight. Hylo chorus very weak involving only a few individuals. June 14 Same locality as above. Night check 11:00-11:45 P.M. (D.S.) of meadow area. Air temp 11:30 P.M. 14.6°C, 3" above ground. Moon casts soft glow, no frozen, mild. I cruised the bridle path, cruised rocky footpath and through much of fern over S side of road without seeing one toad. At
