Along the mole I saw about a score of grebes on the water. A few birds perhaps ducks were flying low over the water. Near the end of the mole, a loon dived as the train passed. There was a Fulica americana on the water near the track. On the bay I saw about fifty ducks going north; most were apparently scoters. All flew quite low over the water and did not go over Goat Island as I saw a flock do yesterday, but went around the eastern end. I saw 2 birds pass to the south. One other pair going south faced about and followed a northward bound flock. Larus californicus & Larus delawarensis which followed the steamer across were both common. There were a good many gulls on the water. San Francisco, bal. to Alameda, bal. 5:15 P.M to 5:35 P.M. Conditions:- Moderate temperature; light wind; less. Larus californicus & Larus delawarensis were common. Near the roundhouse I saw an Ardea herodias standing on a post; another in the shallow water near by; and still another in flight. OCT 19 1874 Alameda, bal. to San Francisco, bal. 7:00 A.M. to 8:00 A.M. Conditions:- Rather cold; clear; no wind.
