One thing we must strive to impress forcibly on the reader, because, if the notion is well grasped, it will enable him to understand plant life so much more vividly. We allude to the continual changes that are going on throughout the whole living fabric of the plant while in its active condition. Cell membrane, the protoplasm, the entire mass of liquid and solid constituents of which the plant consists, are, as we have seen, made up of molecules, each, as it were, with a life of its own, undergoing continual changes according to different circumstances, acting and reacting one upon another so long as any active life remains. C. L. S. C. WORK. By REV. J. H. VINCENT, D.D., SUPERINTENDENT OF INSTRUCTION C. L. S. C. Readings for the month: “Easy Lessons in Vegetable Biology,” by Dr. J. H. Wythe; “Canadian History;” Chautauqua Text-Book No. 24; “Biographical Stories,” by Nathaniel Hawthorne; Required Readings, in THE CHAUTAUQUAN. * * * * * Memorial Day, Sunday, December 9, “Milton’s Day.” See “Memorial Days,” Chautauqua Text-Book, No. 7. Monday, December 10, may be used if preferred. * * * * * Remember the 5 p. m. Sunday “Chautauqua Vesper Service.” Observe the hour personally or as local circles. Now and then a brief public service at this hour may be very profitable. * * * * * There can be no substitute accepted for the “Preparatory Latin course in English.” * * * * * One of our faithful members—a member of the class of ’84—on the first day of October sent this pleasant greeting to the Superintendent of Instruction: “My Dear Doctor—This is opening day. I must send you a line just to keep it—and the Lord keep you!” * * * * * The Sacramento Circle last year answered in writing over 1,000 questions, besides having prepared sixty-two original papers. * * * * * A young lady who has charge of a Young Ladies’ Seminary in Washington, D. C., recently remarked that she had adopted the Chautauqua Text-Books on History as an auxiliary in her school, as they are so condensed and so carefully arranged. She said that at the last examination of her graduating class the influence of the little Text-Books was visible in the remarkable proficiency of the pupils. * * * * * Each C. L. S. C. Local Circle in the study of Biology should secure the services of a local microscopist, if possible. Without the microscope, Biology is like Hamlet with Hamlet left out. * * * * *
