Observations were made on of the squirrel population around the research station in the tall sagebrush area and in the area immediately surrounding the buildings of the station which has a growth of lodgepole pines. The type of vegetation is no doubt influenced by the distrubance of the station activity and by the flow of water from the spring due to be used as a water supply. Observations were made at various times during the day, but the majority were made after 8:30 A.M. when the tempature began to rise and the squirrrels left their burrows to feed in greatest numbers. I found that the squirrels would continue their normal activity if approached quietly and observed from no less than 20 feet. The dates given are those when the squirrels were first observed to be eating a particular food.
