that when you start to compose the theme formally, it almost writes itself, requiring for the most part only expansion and arrangement of ideas. While thus organizing the theme you will reap even more benefits from your early start, for, as you are composing it, you will find new ideas crowding in upon you which you did not know you possessed, but which had been associating themselves in your mind with this topic even when you were unaware of the fact. In writing themes, the principle of distribution of time may also be profitably employed. After you have once written a theme, lay it aside for a while--perhaps a week. Then when you take it up, read it in a detached manner and you will note many places where it may be improved. These benefits are to be enjoyed only when a theme is planned a long time ahead. Hence the rule to start as early as possible. Before leaving the subject of theme-writing, which was called up by the discussion of unconscious memory, another suggestion will be given that may be of service to you. When correcting a theme, employ more than one sense avenue. Do not simply glance over it with your eye. Read it aloud, either to yourself or, better still, to someone else. When you do this you will be amazed to discover how different it sounds and what a new view you secure of it. When you thus change your method of composition, you will find a new group of ideas thronging into your mind. In the auditory rendition of a theme you will discover faults of syntax which escaped you in silent reading. You will note duplication of words, split infinitives, mixed tenses, poorly balanced sentences. Moreover, if your mind has certain peculiarities, you may find even more advantages accruing from such a practice. The author, for example, has a slightly different set of ideas at his disposal according to the medium of expression employed. When writing with a pencil, one set of ideas comes to mind; with a typewriter slightly different ideas arise; when talking to an audience, still different ideas. Three sets of ideas and three vocabularies are thus available for use on any subject. In adopting this device of composing through several mediums, you should combine with it the principle of distributing time already discussed in connection with repetition of impressions. Write a theme one day, then lay it aside for a few days and go back to it with a fresh mind. The rests will be found very beneficial in helping you to get a new viewpoint of the subject.
