The seventh has been constantly employed in teaching. Once during the seventeen years the state of her health demanded a lengthening of the ordinary vacation. She gave herself to out-door exercise, and, when able to walk ten miles with perfect ease, she returned to the school-room. She reports herself to-day as well, and offers as proof, that during the last year she has not lost a single recitation from ill-health. The eighth I have heard from, from time to time; first, as a successful teacher, then as a successful housewife, never as an invalid. The tenth was for many years a most earnest teacher. It is over a year since I heard from her. She was then well. The eleventh is Preceptress of the Normal School at Ypsilanti, Michigan. She is known throughout the State as one of its successful educators. I heard her read last week a most interesting paper, before the State Teachers' Association. She looks as if continuous education and continuous teaching had both been good for her. When asked what she thought of Dr. Clarke's book she laughingly answered, "Look at me." The twelfth answers from Illinois: "I am in good health, and so are my six boys. The two oldest are almost ready for college. They will, of course, go where their mother went. I am daily thankful I studied at Oberlin." Away from the plains of Kansas comes the cheering words of the thirteenth: "A troop of merry children; good health, and a happy home." The fourteenth writes: "Why do you ask if I am sorry that I studied at Oberlin? It is the subject over which my husband and I can grow enthusiastic at any time. My health impaired there? _No._ We hope to send our daughter soon." The fifteenth we have not heard from for some time. We only know that as a minister's wife her life has not been an idle one. Ten years after graduating she was in ordinary health. The sixteenth. Again we hear no response. "In Memoriam" is written over her grave. The seventeenth lives in Mississippi. She was well when visited by some of our Union boys during the war. I have no later report to give. The eighteenth certainly does not count herself an invalid; and The nineteenth, who was, as a school-girl, the very personation of energy, looks forward to years of useful labor. We are told that we must not look at the blooming class on graduation day for the effects of co-education. We have not. We have waited seventeen years. Have we found anything there to frighten even a physiologist?
