By this time certain matters concerning composition should be clear. In the first place, our purpose as students of English composition is to learn how to express our own thoughts. It follows, therefore, that whether we talk or write, it is our task to put our thoughts together in our own way, not in another's. Hence, as a rule, we shall speak or write from experience. Naturally, it is important for our hearers or readers that we discuss but one subject, or part of a subject, at a time; and in order that our composition, whether oral or written, may be a unit, we shall do well - by way of preparation - to talk over the subject with some one, and to make a careful outline of what we have to say.
