WE wish to urge upon the members of the Senior Class the importance of immediately writing their "lives" for the Class-Book. If it is not done now, it will probably never be done at all; and the value of the book will be very much diminished if it does not contain the lives of all the members of the class. The Secretary, this year, does not ask for an elaborate autobiography, with one's descent traced back to Adam, but only for a brief statement of the way in which and the place where the student's life has been passed. We hope that the members of the class will give a tolerably detailed account of the way in which they have spent their college life, the societies they have been members of, their connection with athletics, the rooms they have occupied, and, if space is left, we would suggest that every one should append to his life a list of the electives he has taken while in college.
