No "inherent difficulty in adjusting, in the same institution, the methods of instruction to the physiological needs of each sex" has been found. It should not be overlooked, that there is a large Preparatory Department, composed of hundreds of boys and girls, in connection with the college, so that the experiment at Oberlin has not included a small number. Last year there were in the various departments 1,371 students, 648 of whom were girls. The excuse of sickness for an absence is never questioned. This is well-known by every girl in the school; and yet we have never heard a Professor in the College, or a teacher in the Preparatory Department complain that girls were oftener absent than boys. The Professor in Physiology has kindly sent me the following:--"An examination of my class-book, in all my recitations for the last five years, shows but a very slight difference in the average number of absences from recitations, for all causes, excused and unexcused, of women and men, viz.:--for each man, 35.31, for each woman, 36.76." There is another fact which ought to be mentioned. Many of the girls who have completed a course of study at Oberlin have, at the same time, supported themselves. This they have done mostly by teaching, which has left them little time for rest or recreation even during the short vacations.[53] Of course this would have been impossible, if the expenses here were as great as in our eastern colleges; but reduce them to the lowest minimum, and, at the present rate of women's wages, the meeting of these expenses in addition to regular college-work is no slight consideration. Is it any wonder if some who might endure the one, fail under the weight of both? Several years ago, some benevolent Quaker ladies of Philadelphia gave a few hundred dollars for the benefit of this class of girls, and within the last few months others have added to the sum. It is now proposed to secure a permanent fund of $10,000, the interest to be used in helping those who are helping themselves. Noticing one other point, we are done. There is an intimation by our author, that boys educated in schools like Oberlin become effeminate, and girls masculine. If such men as our United States Geologist, whose enthusiastic devotion to science has led to the exploring of the head-waters of the Yellowstone, and the opening with its rich treasures of the great Northwest--and if our representative in Congress, who voted against the salary bill and the retroactive clause, are specimens of effeminate men, the country can endure more of them.
