May 31st, Caught a young Oregon Jemco just out of the nest in a "gur-whizz" trap, This is very early for this region, Moll Harbor, June 1st, Shot a Robin. It was with two others and seemed to be a migrant. Have noticed no others near this camp. June 2. A porpoise brought by fisherman appears to be a Phocaina, but not communis. I think it was a female, but did not dissect. Its length was 1740 mm.; pectoral fin 215; dorsal fin 170; breadth of caudal 415; I photographed it. Bittjohn saved the skull June 9. Came in yesterday from a four day trip to the lakes. Saw a considerable beaver work. Dams were very frequent in some of the small streams, often raising the water so that it reached the next dam above. Some of the dams were quite old. I saw some embankments over- grown with trees, that were washed away by the stream so that the pond was dried. Other old dams that appeared to be uninhabited were still kept in repair. Probably these were used by one or more beavers in winter, who went elsewhere in summer. We saw fresh cuttings in many places along the lake beaches,
