Your mind, like your body is a thing where of the powers are developed by effort. That is principal use, as I see it, of tard work in studies. Unless you train your body you cannot be an athlete, and unless you train your mind you cannot be much of a scholar. The four miles an oarsman covers at top speed is in itself nothing to the good, but the physical capacity to hold out over the course is thought to be of some worth, So a good part of what you learn by hard study may not be permanently retained, and may not seem to be of much final value, but you mind is a better and more powerful instrument because you have learned it. Knowledge is power, but still more the faculty of acquiring and using knowledge is power. f you have a trained and powerful mind, you are bound to have stored it with something but its value is more in what it can do. what it can grasp and use, than in what it contains; and if were possible, as it is not, to come out of college with a trained and disciplines mind and nothing useful in it, you would still be ahead, and still, in a manner, educated.
