W. Rieger 1951 Journal 14 Oct. Calif.: Contra Costa Co. Visited only the Pinchurst Triturus study area, 0830-0845 hrs. Clear, warm, sunny. 20 Oct. Calif.: Napa Co. Party of Bill Woodin, Richard Zweifel and myself visited certain spots in Napa and Sonoma Co. Objectives were to collect Rana boylii and Ancoides flavipunctatus for Zweifel, Triturus for me. Left Berkeley 0715 hrs., Woodin providing transportation. Arrived at Calistoga 0915 hrs. First stop made at Robert Louis Stevenson Home (now a State Monument) 2 mi. E, 1 mi S Mt. St. Helena. Here, because of recent rains soil under exposed small litter damp but in sheltered areas and under larger pieces of litter soil dry. Apparently the rains here have been light so far. Also, about ½ mi. up the canyon directly above the house we found the Silverado Silverado Mine ("abandoned" on the topographic sheets) now with a locked and blocked entrance. Because of seepage in mine area and from collecting tanks just below the mine there were areas of saturated soil present. From vicinity of mine and buildings down canyon the party collected 4 young Esothia, 1 Ancoides
