 Jan., I9O 7 AxhIONG THE GULLS ON KLAMATH LAKE 3 skirmishing about the country to pick up a living in the fields, following the plow all day long as blackbirds do, and fighting at the farmer's heels for angle worms. I have seen others rummage daily about pig-pens and gorge on the offal thrown out from the slaughter-houses. If any bird is useful to man. the gull is certainly of economic importance as a scavenger.
