San Diego, Jan 29, Saturday. Spent the morning at Mission Gardens on the top of the city area and the edge of Mission Canyon that heads into Mission Bay. Here we had a splendid view all over the area but down to the Mt. The little dry run in the Canyon could never have cut this mile wide gully. It must have done so when there was more water. It was the same view I had yesterday, only more spirit and better. In the afternoon collected Pleisiotreme shells, at Crown Point of Mission Bay. The variety is not at all large, and 99% of the fauna is made up of about half a dozen bivalves. All are crushed together in the sand that has flowed from Mica. The rest are sand dollars, four three small gast, and series of two lagen mes. One small Dentalium. Some sand filling of cornutube, but not a sign of bygga.
