A third and perhaps the most common source of error is found in the particular wording given to the central thought. In order to be perfectly definite and accurate any thought should be expressed in the form of a full statement. It ordinarily takes at least a whole sentence to express a whole thought. But it is very common for students even, who have formed the habit of thinking by points, to allow brief headings, consisting of single words or short phrases, to represent entire thoughts. Although such headings, on account of their brevity, may be useful, they are merely names for the thought, not statements of the thought itself; and it means the loosest kind of thinking to stop with them. A mere title, as a lecture "About Russia," for instance, designates only the outside limits to which a person confines himself—provided he sticks to his theme. It often tells no more about the substance of the thought within those limits than a man's name tells about his character. It is usually easy to tell "what a page is about"; but it usually requires keen thinking to word its principal idea sharply in a full sentence. Many students are inaccurate in the interpretation of authors and in their own thinking, not so much because they lack mental ability as because they lack the energy to continue their thinking to this point of wording the central idea accurately in a full sentence.

THE ABILITY OF CHILDREN TO GROUP FACTS INTO POINTS.

The grouping of facts into points requires ability to perceive that some statements are more valuable than others, without reference to the space that they happen to occupy on the printed page; it presupposes, also, the power to rearrange a stranger's ideas. It is, therefore, an aggressive kind of work, in which even adults often fail to distinguish themselves. Can children be expected to assume such responsibility?

Proofs of such ability. 1. As shown by children ten years old and younger.

Proof that any ten-year-old child has already assumed it in a simple way for some years is contained in the following facts:—

1. Long before the school age is reached a child has had much practice in picking out the logical subjects of sentences, inasmuch as he has learned to comprehend statements made to him. Distinguishing the subject of a sentence is the same kind of work as distinguishing the subject of a paragraph or chapter, only it is simpler.

2. Any six-year-old child has, likewise, had much practice in detecting the subject of short conversations, especially of those of interest to him. If he happens to overhear a conversation between his parent and teacher touching a possible punishment for himself, he can be trusted to sum it up and get the gist of it all, even though some of the words do not reach him. That is exactly the kind of thinking required in getting the point of a lecture.

3. In relating fairy tales and other stories, during the first years at school, children easily fall into the habit of relating a part, or a point, at a time. And, if the memory or the courage fails, the teacher gives help by asking, "What will you tell about first? And then? And then?" thus setting them right, and keeping them so, by having them divide the story into its principal sections.

4. In composition, in the lower and middle grades, the paragraphing of thought, first as presented on the printed page, then as called for in oral recitation and in conversation, and finally in the child's written form, is a prominent subject of instruction. No one maintains that such work is unnatural, or too difficult, for such young children.

5. Development instruction, which has already been mentioned as peculiarly successful with young children, would be impossible if children were unable to appreciate the character of a principal thought, as the topic or point for discussion, and of other thoughts as subordinate to it.
