Swan Lake Research Project: A detailed study of the flora of this lake was carried on from the middle of June through the first week in August. During this period plankton algae samples were taken weekly. These samples were secured with the cooperation of Drs. L. Floyd Clarke, George Baxter, and other personnel at the Research Station. In addition frequent and numerous samples were also secured of the algae attached to other aquatic plants and the bottom. Specimens of macroscopic flowering plants were secured as they matured sufficiently for identification. The taking of plankton samples was continued through the month of August by Drs. Clarke and Baxter. Project Numbers 75 and 81.
