"In regard to regular study producing pain, haemorrhage or irregularity, I do not think these disturbances are caused so much by application to study as by want of care and prudence at the menstrual period, and of fresh air and exercise during the interval. * * * I think that labor, both mental and physical, should be diminished at the menstrual period, for at this time the ovaries and uterus are intensely engorged, and the nervous system is in an unusually excitable condition. Do not understand me that girls should be excused from all physical labor, but only that they should not undertake unusually hard work, and should avoid long walks, giving themselves as much rest as possible. * * * I do not think, however, that any of these things should debar a woman from pursuing a regular course of study, only let her exercise care and prudence at the menstrual period. It is not uncommon for this function to be arrested by any great change of circumstances, as when a girl leaves home and goes to school, where there is almost an entire change of habits. Many cases came under my observation while at the Seminary, among the junior class (first year), of suppression or irregularity for three or six months, all then proceeding regularly without medical interference. I think women suffering from ordinary female troubles are benefited by regular exercise; for a want of proper exercise affects injuriously the general health, thereby increasing the uterine disorder. If a girl with any _great_ female trouble should enter the Seminary, her troubles would be increased, not from the regular work, but by going over the stairs."
