wheneast of Goat Island, about twenty cormo- rants crossed our bows very close, going southward in their usual navy style, keeping quite close to the water. For the past two or three mornings I have noticed two or three cormorants sitting on a hor- zontal stick placed on two vertical ones, apparently the remains of a blind, situated southward of the mole. Oct. 27, 1907. Alameda to and from San Francisco, cal. Conditions :- Warm; quite clear; no wind. Larus californicus, in adult and immature plumage, was very common on the bay, a large flock being seen near the "Maryland." About three o'clock when coming down Market Street, I saw a number of gulls circling high in the air above Davis Street. Along the mole and seawall several small grebes and one or two large grebes or cormorants were seen at high tide. Oct. 30, 1907. Alameda to and from San Francisco, cal.
