Your memory is bad, perhaps, but I can tell you two secrets that will cure the worst memory. One of them is to read a subject when interested; the other is not only to read, but think. When you have read a paragraph, or a page, stop, close the book, and try to remember the ideas on the page, and not only call them vaguely to mind, but put them in words and speak them out. Faithfully follow these two rules, and you have the golden key of knowledge. Besides inattentive reading, there are other things injurious to the memory. One is the habit of skimming over newspapers, items of news, smart remarks, bits of information, political reflections, fashion notes, so that all is a confused jumble, never to be thought of again, thus diligently cultivating a habit of careless reading hard to break. Another is the reading of trashy novels.—Exchange.
