Gullion 1949 Journal -134- Aug 17 Big Lagoon, Humboldt Co., Calif. of me but left before I could get it. Saw a pair of Marsh Wrens feeding 3 freshly killed young. Moved on over towards the S arm of the Old Mouth, collecting a Least Sandpiper on the way, and observing an extremely dark Virginia Rail. Crossed both parts of the S arm, and worked up the W side. Saw a ♀ Buffy Duck opposite the end of Cross Channel, knocked down but mutilated a Rough-winged Swallow, saw 2 immature Ring- billed Gulls flying in the fog. Incidentally, about 10 a.m. the water of the marsh had warmed up so much that the cool breeze from the ocean formed a dense low fog, on the water surface, making long range observation impossible. At noon the fog still had not completely burned off. Worked on along the W side of the Old Mouth towards the S W end of the bridge- near there I collected 2 of 4 Pied- billed Grebes. Returning, I forded Old Mouth just N of the end of Cross Channel, worked on along
