warenis followed the boat in about equal numbers. Several Larus heermanni appeared occasionally but always at a good distance. A mess were passing quite close to the other steamer, something was thrown overboard from our vessel. Immediately the gulls assembled, those following the other boat came also. Usually as a gull swoops down for something it gives a scream. A cormorant was sitting on one of the further piles of the mole when the boat left. Two more going east passed us off Goat Island. Here I also saw three terns. Along the waterfront of San Francisco gulls were abundant; very few Larus heermanni, however. San Francisco to Alameda, Cal. Conditions: 5:15 to 5:45 P.M. Strong S&W wind; moderate temperature; rain. (Between 10:00 A.M. and 3:00 P.M. 2-day it was clear.) Between 7:00 and 8:00 P.M. there was no wind or rain, but it was very threatening with occasional flashes of lightning. After that the wind and rain began again.) On the bay I saw a few terns off Goat Island; three or four Larus heermanni; a good many Larus delawarensis; and a good many Larus californicus. Near the roundhouse I saw four Ardea herodias in the shallow water. There were a good many gulls and a few large shore birds on the exposed sand and mud. Sep. 24, 1904 Alameda to San Francisco, Cal.
