on its weathered surfaces. Strong north wind makes work disagreeable. I found an ironstone concretion containing gasteropods resembling Vivipara and some bivalves resembling Corbicula and collected 70 and Harry found a stratum at the dam and collected therefrom 110 bivalves of two or more species. We then had lunch, fed the team and started down creek. On the way down I collected 40 more at the same place where Harry had worked while the others were looking at hawks nests. About 7 to 9 miles further down creek found a heronry and discovered an outcrop from which I took 75 specimens of Ostrea glabra and Corbicula , making a total of 400 specimens for the day. Also found a ledge containing many gasteropoda , so we went a mile down creek where we could get water from a well and camped. Have seen no water in creek since leaving last camp. Road has followed creek and is poor, with many gates.
