or measuring instruments. He investigates further. By moving a few yards to the top of a hillock he notices that the farther ditch is entirely a dirt construction whereas the one he occupies is a concrete one. He confirms this intelligence by looking at his map which shows the ditches to be as he has made them out. He, therefore, heads his message, “Concrete irrigation ditch 500 yards east of southeast corner of Catholic Church.” This is a case where an added word has made the meaning more proof against error. There are similar cases where a word taken away, or the change of a phrase, clause, or sentence, will make the recipient of the communication more sure of the true state of affairs. To sum up as far as we have gone, we see that our object is to put military communication into proper form; that the failure to make our expression of the utmost brevity and clarity causes loss of efficiency, battles, and life; that a condition of inability to express ourselves exists widely; that by starting as early as we can to practice clear and brief form within the bounds of rhetorical and military rules (which, after all, are nothing more than those of common sense), we shall overcome this deficiency; and that for ourselves we are going to direct our course along two highways, viz.: (1) To learn to find quickly expressions which will cover information and decisions that are trying to struggle into language; and (2) To plant that information or decision in the recipient’s understanding exactly as it was rooted in our minds. We have, so far, rehearsed the general attitude we must adopt toward conquering indefinite and lengthy expression. Because this weakness is so natural to us, we cannot afford to trifle with it if we wish to become a factor in battle. Positive decisions and information must be given in a positive way. Since no other kind of decision or information is countenanced in the military service, we must search for specific means of having our language stand sturdily by itself. It must not choke our idea or our will, however little. Our decisiveness must reach our farthest superior or subordinate; and _words_, _phrases_, _clauses_, _sentences_, and _paragraphs_ are going to be our only representatives. They alone will stand for us. Every pencil mark on that paper will be a part of the photograph of our intelligence. Our phraseology will be ourselves. We shall be judged by it, and rightly so, at a time when we shall have no chance to offer an amendment, an excuse, or an _I-didn’t-mean-quite-that_.
