Proportion in a speech is attained by a nice adjustment of time. How fully you may treat your subject it is not always for you to say. Let ten minutes mean neither nine nor eleven--though better nine than eleven, at all events. You wouldn't steal a man's watch; no more should you steal the time of the succeeding speaker, or that of the audience. There is no need to overstep time-limits if you make your preparation adequate and divide your subject so as to give each thought its due proportion of attention--and no more. Blessed is the man that maketh short speeches, for he shall be invited to speak again.
Another matter of prime importance is, what part of your address demands the most emphasis. This once decided, you will know where to place that pivotal section so as to give it the greatest strategic value, and what degree of preparation must be given to that central thought so that the vital part may not be submerged by non-essentials. Many a speaker has awakened to find that he has burnt up eight minutes of a ten-minute speech in merely getting up steam. That is like spending eighty percent of your building-money on the vestibule of the house.
The same sense of proportion must tell you to stop precisely when you are through--and it is to be hoped that you will discover the arrival of that period before your audience does.
Tapping Original Sources
The surest way to give life to speech-material is to gather your facts at first hand. Your words come with the weight of authority when you can say, "I have examined the employment rolls of every mill in this district and find that thirty-two per cent of the children employed are under the legal age." No citation of authorities can equal that. You must adopt the methods of the reporter and find out the facts underlying your argument or appeal. To do so may prove laborious, but it should not be irksome, for the great world of fact teems with interest, and over and above all is the sense of power that will come to you from original investigation. To see and feel the facts you are discussing will react upon you much more powerfully than if you were to secure the facts at second hand.
Live an active life among people who are doing worth-while things, keep eyes and ears and mind and heart open to absorb truth, and then tell of the things you know, as if you know them. The world will listen, for the world loves nothing so much as real life.
How to Use a Library
Unsuspected treasures lie in the smallest library. Even when the owner has read every last page of his books it is only in rare instances that he has full indexes to all of them, either in his mind or on paper, so as to make available the vast number of varied subjects touched upon or treated in volumes whose titles would never suggest such topics.
For this reason it is a good thing to take an odd hour now and then to browse. Take down one volume after another and look over its table of contents and its index. (It is a reproach to any author of a serious book not to have provided a full index, with cross references.) Then glance over the pages, making notes, mental or physical, of material that looks interesting and usable. Most libraries contain volumes that the owner is "going to read some day." A familiarity with even the contents of such books on your own shelves will enable you to refer to them when you want help. Writings read long ago should be treated in the same way--in every chapter some surprise lurks to delight you.
In looking up a subject do not be discouraged if you do not find it indexed or outlined in the table of contents--you are pretty sure to discover some material under a related title.
