Note: Control operations in yellow pine in Oregon are confined this spring to the Whitworth Creek and Horsefly division. Most of the work is being done under the direction of Assistant Supervisor Lawrence Frizzell with a twenty to twenty-five man crew in cooperation with the Klamath Forest Protective Association. The method employed is felling, peeling, and buring of the infested trees. On one of the control areas, the Horsefly Division, the western pine beetle (D. brevicomis) has killed over 20 percent of the stand during the three-year period, 1926 to 1928. The Indian Service is doing considerable control work in the southeastern part of the Klamath Indian Reservation with the aid of a special $25,000 appropriation. A. J.
