stories in your imagination, years after. You will find that your favorite characters will take on a new reality for you, and will become as old friends in whose company you may enjoy yourself at any time, and whom you may dismiss when they tire you, without offense. In the case of scientific treatises, essays, etc., you may follow a similar plan by dividing the work into small sections and mentally reviewing the _thought_--(not the words) of each section until you make it your own; and then by adding new sections to your review, you may gradually absorb and master the entire work. All this requires time, work and patience, but you will be repaid for your expenditure. You will find that this plan will soon render you impatient at books of little consequence, and will drive you to the best books on any given subject. You will begin to begrudge your time and attention, and hesitate about bestowing them upon any but the very best books. But in this you gain. In order to fully acquaint yourself with a book, before reading it you should familiarize yourself with its general character. To do this you should pay attention to the full title, and the sub-title, if there be any; the name of the author and the list of other books that he has written, if they are noted on the title page, or the one preceding it, according to the usual custom. You should read the preface and study carefully the table of contents, that you may know the field or general subject covered by the book--in other words endeavor to get the general outline of the book, into which you may afterwards fill in the details. In reading a book of serious import, you should make it a point to fully grasp the meaning of each paragraph before passing on to the next one. Let nothing pass you that you do not understand, at least in a general way. Consult the dictionary for words not familiar to you, so that you may grasp the full idea intended to be expressed. At the end of each chapter, section and part, you should review that which you have read, until you are able to form a mental picture of the general ideas contained therein.
