In the above selection we find that each group of sentences is related to some main topic. A more extended observation of good writing will give the same result. Men naturally think in sentence groups. A group of sentences related to each other and to the central idea is called a +paragraph.+
+38. Topic Statement.+—In the three paragraphs of the selection on page 67, notice that the first sentence in each tells what the paragraph is about. In a well-written paragraph it is possible to select the phrase or sentence that states the main thought. If such a sentence does not occur in the paragraph itself, one can be framed that will express clearly and concisely the chief idea of the paragraph. This brief, comprehensive summary of the contents of a paragraph is called the topic statement.
In order to master the thought of what we read we must be able to select or to make the successive topic statements, and in order to express our own thoughts clearly we must write our paragraphs so that our readers may easily grasp the topic statement of each.
When expressed in the paragraph, the topic statement may be a part of a sentence, a whole sentence, or it may extend through two sentences. It is usual to place the topic statement first, but it may be preceded by one or more introductory sentences, or even withheld until the end of the paragraph. For emphasis it may be repeated, though usually in a slightly different form.
EXERCISES
Determine the topic statements of the following paragraphs. If one is not expressed, make one.
1. No less valuable is the mental stimulus of play. The child is trained by it to quick perception, rapid judgment, prompt decision. His imagination cunningly suggests a thousand things to be done, and then trains the will and every power of body and mind in the effort to do them. The sports of childhood are admirably adapted to quicken the senses and sharpen the wits. Nature has effective ways in her school of securing the exercise which is needed to develop every mental and every bodily power. She fills the activity brimful of enjoyment, and then gives her children freedom, assured that they will be their own best teachers.

2. Our Common Law comes from England, and originated there in custom. It is often called the unwritten law, because unwritten in origin, though there are now many books describing it. Its principles originated as habits of the people, five hundred, eight hundred, years ago, perhaps some of them back in the time when the half-savage Saxons landed on the shores of England. When the time came that the government, through its courts, punished the breach of a custom, from that time the custom was a law. And so the English people acquired these laws, one after another, just as they were acquiring at the same time the habits of making roads, using forks at table, manufacturing, meeting in Parliament, using firearms, and all the other habits of civilization. When the colonists came to America, they brought the English Common Law with them, not in a book, but in their minds, a part of their life, like their religion.
