CHAUTAUQUA LITERARY AND SCIENTIFIC CIRCLE. _President_—Lewis Miller. _Superintendent of Instruction_—J. H. Vincent, D.D. _Counselors_—Lyman Abbott, D.D.; J. M. Gibson, D.D.; Bishop H. W. Warren, D.D.; W. C. Wilkinson, D.D. _Office Secretary_—Miss Kate F. Kimball. _General Secretary_—A. M. Martin. 1.—AIM. This new organization aims to promote habits of reading and study in nature, art, science, and in secular and sacred literature, in connection with the routine of daily life (especially among those whose educational advantages have been limited), so as to secure to them the college student’s general outlook upon the world and life, and to develop the habit of close, connected, persistent thinking. 2.—METHODS. It proposes to encourage individual study in lines and by text-books which shall be indicated; by local circles for mutual help and encouragement in such studies; by summer courses of lectures and “students’ sessions” at Chautauqua, and by written reports and examinations. 3.—COURSE OF STUDY. The course of study prescribed by the C. L. S. C. shall cover a period of four years. 4.—ARRANGEMENT OF CLASSES. _Each year’s Course of Study will be considered the “First Year” for new pupils_ whether it be the first, second, third, or fourth of the four years’ course. For example, “the class of 1887,” instead of beginning October, 1883, with the same studies which were pursued in 1882-83 by “the class of 1886,” will fall in with “the class of ’86,” and take for their first year the second year’s course of the ’86 class. The first year for “the class of 1886” will thus in due time become the fourth year for “the class of 1887.” 5.—C. L. S. C. COURSE OF READING, 1883-84. I. REQUIRED. History of Greece.[I] By Prof. T.
