"I would advise you to read with a pen in your hand, and enter in a little book short hints of what you find that is curious, or that may be useful; for this will be the best method of imprinting such particulars in your memory, where they will be ready, either for practice on some future occasion, if they are matters of utility, or, at least, to adorn and improve your conversation, if they are rather points of curiosity; and, as many of the terms of science are such as you can not have met with in your common reading, and may therefore be unacquainted with, I think it would be well for you to have a good dictionary at hand, to consult immediately when you meet with a word you do not comprehend the precise meaning of. "This may, at first, seem troublesome and interrupting; but it is a trouble that will daily diminish, as you will daily find less and less occasion for your dictionary, as you become more acquainted with the terms; and, in the mean time, you will read with more satisfaction, because with more understanding. When any point occurs in which you would be glad to have further information than your book affords you, I beg you would not in the least apprehend that I should think it a trouble to receive and answer your questions. It will be a pleasure, and no trouble. For though I may not be able, out of my own little stock of knowledge, to afford you what you require, I can easily direct you to the books where it may most readily be found. "Adieu, and believe me ever, my dear friend, "B. FRANKLIN." Reading with pen or pencil in hand fixes the attention, assists method, strengthens purpose, and charges memory with its sacred trust. A note-book for this purpose is the most convenient method of preserving these treasures. Professor Atkinson, of the Massachusetts Institute of Technology, advises students thus: "Gather up the scraps and fragments of thought on whatever subject you may be studying--for, of course, by a note-book I do not mean a mere receptacle for odds and ends, a literary dust-bin--but acquire the habit of gathering every thing, whenever and wherever you find it, that belongs in your lines of study, and you will be surprised to see how such fragments will arrange themselves into an orderly whole by the very organizing power of your own thinking, acting in a definite direction. This is a true process of self-education; but you see it is no mechanical process of mere aggregation. It requires activity of thought--but without that what is any reading but mere passive amusement? And it requires method. I have myself a sort of literary bookkeeping. I keep a day-book, and, at my leisure, I post my literary accounts, bringing together in proper groups the fruits of much casual reading."
