This "cramming", I suspect, is done in schools even much more than most teachers realize. Many students everywhere almost entirely neglect study day by day and then by a dynamogenic spurt learn the whole subject, and sometimes adequately, and now and then even permanently, within a week or so, or even a few days. In order to accomplish this, they have to have this training-control of mind, which is really a training of the body. But a student who lacks this knowledge of how to study, how to steadily force his mind for repeated effective periods along hard, because definite, directions, cannot accomplish such intensive acquirement either soon or easily. Such students (and the great majority of learners are of this latter type) must first learn how to study in this way; or else use the ordinary traditional method for average students such as the average school everywhere provides!
Here we are considering the use of textbooks by a student who knows how to make the most of them. This dynamogenic process (the word's meaning is obvious) is a pleasure as well as a necessity, and is widely open to all. But few indeed realize that they possess this all-important power of rapid and easy learning from textbooks,
