Two or three Mimenius hudsonicus were seen this evening near the roundhouse; they were feeding in the muck and not on top of the marsh as is often their wont. August 26, 1907. Alameda to and from San Francisco, Cal. Conditions: - Moderate temperature; NW wind; over- cast in the morning. On the great expanse of sand left bare by the tide this morning near the mole, there were three or four hundred gulls, all near the water's edge. This evening on the mud along the seawall on the north side of Oakland creek there were a great many. On Greenwich St. Wharf No. 2 in San Fran- cisco I saw a great many gulls to-day. They were all on the roof of the large shed. Near the top of the roof were Larus californicus and Larus occidentalis, while lower down and closely bunched were a good many Larus heermanni. On the broad level part of the roof I found the skeleton of a bird (gull), and the remains of several 5 or 6 sick fish. Gulls fairly common on the bay to-day.
