A has always preferred books of fact to books of fancy--"true books," as he called them; but now he enjoys fairy tales more than he did when he was younger. This may be because the fact behind the fancy now makes a stronger appeal. The following list represents six months' reading, from the age of 7 years 0 months to 7 years 6 months, some of the books being read to A, to reduce eyestrain. [4] _On Plymouth Rock_ S. A. Drake _Four Great Americans_ J. Baldwin _Stories of New York_ A. T. Lovering _The Children's City_ E. Singleton _The Burgess Bird Book_ Thornton Burgess _The Burgess Animal Book_ _The Empire State_ J. W. Redway _Around the World with the Children_ F. G. Carpenter _East o' the Sun and West o' the Moon_ G. W. Dasent _Miles Standish_ H. W. Longfellow _The Wreck of the Hesperus_ H. W. Longfellow _Fables_ Bulfinch _Aesop's Fables_ _Tales and Teachings from the Pentateuch_ M. M. Joseph _The Little Gray Grandmother_ Carolyn S. Bailey _Stories of the Bible_ Louise M. Pleasanton _The Pied Piper of Hamelin_ R. Browning _Tanglewood Tales_ N. Hawthorne _First Jungle Book_ R. Kipling _Second Jungle Book_ R. Kipling _Poems_ J. W. Riley _Poems_ Eugene Field _Poems_ R. L. Stevenson _The Wonder Book of Knowledge_ _The Blue Bird_ M. Maeterlinck _Historic Boyhoods_ R. S. Holland _The Friendly Stars_ M. E. Martin This list gives an idea of the reading preferences of A, at the age of 7 years. Within the year following, the preference for biography and autobiography developed. _Interest in astronomy_. Because other very young children of more than 180 IQ known to the present writer had been especially interested in astronomy--particularly Child E--it was desired to observe what would be the reaction of A if knowledge of astronomy were made accessible to him. Books which had interested Child E at the age of 6 to 7 years were therefore made accessible to A. He at once became interested in the heavenly bodies and their movements. _Tendency to classify and diagram_. A's love of classifying-- first noted at the age of about 12 months--is a conspicuous characteristic. He classifies events, objects, names, numbers, and other data of experience. He can think in terms of diagrams and sometimes draws a diagram to clarify or condense his meaning.
