R. W. Bullock[14] classified and tabulated 2,000 returns from school-children from the third to the twelfth grade, both inclusive, concerning their reading. From this it appeared that the average boy of the third grade "read 4.9 books in six months; that the average falls to 3.6 in the fourth and fifth grades and rises to a maximum of 6.5 at the seventh grade, then drops quite regularly to 3 in the twelfth grade at the end of the high school course." The independent tabulation of returns from other cities showed little variation. "Grade for grade, the girls read more than the boys, and as a rule they reach their maximum a year sooner, and from a general maximum of 5.9 books there is a drop to 3.3 at the end of the course." The age of reading may be postponed or accelerated perhaps nearly a year by the absence or presence of library facilities. Tabulating the short stories read per week, it was found that these averaged 2.1 in the third grade, rose to 7.7 per week in the seventh grade, and in the twelfth had fallen to 2.3, showing the same general tendency. The percentage tables for boys' preference for eight classes of stories are here only suggestive. "War stories seem popular with third grade boys, and that liking seems well marked through the sixth, seventh, and eighth grades. Stories of adventure are popular all through the heroic period, reaching their maximum in the eighth and ninth grades. The liking for biography and travel or exploration grows gradually to a climax in the ninth grade, and remains well up through the course. The tender sentiment has little charm for the average grade boy, and only in the high school course does he acknowledge any considerable use of love stories. In the sixth grade he is fond of detective stories, but they lose their charm for him as he grows older." For girls, "stories of adventure are popular in the sixth grade, and stories of travel are always enjoyed. The girl likes biography, but in the high school, true to her sex, she prefers stories of great women rather than great men, but because she can not get them reads those of men. Pity it is that the biographies of so few of the world's many great women are written. The taste for love stories increases steadily to the end of the high school course. Beyond that we have no record." Thus "the maximum amount of reading is done in every instance between the sixth and eighth grades, the average being in the seventh grade at an average age of fourteen and one-tenth years." Seventy-five per cent of all discuss their reading with some one, and the writer urges that "when ninety-five per cent of the boys prefer adventure or seventy-five per cent of the girls prefer love stories, that is what they are going to read," and the duty of the teacher or librarian is to see that they have both in the highest, purest form.
