C. who, being members of local circles, wish to continue in the same general line of reading as undergraduate members, a White Crystal Seal Course is prepared. This consists mainly of books belonging to the current year’s study, but not previously read by the graduates. An additional white seal is also offered to the graduates, the books for which are specified under paragraph 4. Some of these books were in the first four year’s course, and are therefore to be _re_-read. The payment of one dollar at one time entitles a graduate to the White Crystal and White Seals for four years. If only fifty cents is paid, it will be credited for but one year. THE CHAUTAUQUAN.
