B. Make an outline of the following paragraph:—

1. The armor of the different classes was also accurately ordered by the law. The first class was ordered to wear for the defense of the body, brazen helmets, shields, and coats of mail, and to bear spears and swords, excepting the mechanics, who were to carry the necessary military engines and to serve without arms. The members of the second class, excepting that they had bucklers instead of shields and wore no coats of mail, were permitted to bear the same armor and to carry the sword and spear. The third class had the same armor as the second, excepting that they could not wear greaves for the protection of their legs. The fourth had no arms excepting a spear and a long javelin. The fifth merely carried slings and stones for use in them. To this class belonged the trumpeters and horn blowers.

C. In preparing your other lessons for to-day, make outlines of the paragraphs.

+Theme XIX.+—Reproduce the thought of some paragraph read to you by the teacher.

(Do not attempt to remember the language. Try to get the main thought of what is read and then write a paragraph which sets forth that same idea. Use different illustrations if you can.)

NOTE.—This theme may be repeated as many times as seems desirable.

+40. Importance of the Paragraph.+—Emphasis needs to be laid upon the importance of the paragraph. Our ability to express our thoughts clearly depends, to a large extent, upon our skill in constructing paragraphs. The writing of correct sentences is not sufficient. Though each of a series of sentences may be correct, they may, as a whole, say but little, and that very poorly; while another set of sentences, which cluster around some central idea, may set it forth most effectively. It is only by giving our sentence groups that unity of thought which combines them into paragraphs that we make them most effective. A well-constructed paragraph will make clear some idea, and a series of such paragraphs, related to each other and properly arranged, will set forth the sum of our thoughts on any subject.

+41. Paragraph Length.+—The proper length of a paragraph cannot be determined by rule. Sometimes the thought to be presented will require several sentences; sometimes two or three will be sufficient. A single illustration may make a topic statement clear, or several illustrations may be required. The writer must judge when he has included enough to make his meaning understood, and must avoid including so much that the reader will become weary. Usually a paragraph that exceeds three hundred words will be found too long, or else it will contain more than one main idea, each of which could have been presented more effectively in a separate paragraph.
