Nearly forty years' experience as a teacher has shown me how little I truly know of a subject until I begin to explain it or teach it. Let any young person try the experiment of giving in conversation, briefly and connectedly, and in the simplest language, the chief points of any book or article he has read, and he will at once see what I mean. The gaps that are likely to appear in the knowledge that he felt was his own, will no doubt be very surprising. I know of no training superior to this in utilizing one's reading, in strengthening the memory, and in forming habits of clear, connected statement. It will doubtless teach other things than those I have just mentioned, which the persons who honestly make the experiment will find out for themselves. Children who read can be encouraged to give, in a familiar way, the interesting parts of the books they have read, with great advantage to all concerned. More than one youth I know has laid the foundation of intellectual tastes in a New England family, where hearty encouragement was given to children and adults in their attempts to sketch the lectures they had heard the evening previous. The same thing was done with books. —Christian Union.
