He absorbed information easily and quickly and, regardless of the grade in which he was placed or the length of time he had been in the grade, his work and his ratings were always much beyond those of his classmates. During these early years G preferred being alone with his books to playing with other children. His parents intelligently sought advice on the correction of this and encouraged him, successfully, to play with other children, first with those younger than he, and then with children of his own age. He made a ready adaptation, and in time had a group of boys with whom he played and who were sometimes invited by his father to accompany them on Saturday afternoon excursions. He developed an interest in all sorts of ball games and became a good swimmer. G read widely, and his parents from the beginning exercised some supervision over the character of the books provided for him, and they read to him at bedtime, about an hour daily. There were included in his reading not only a large selection of children's books and stories but also books of history, mythology, biography, poetry, science and art. The Saturday excursions to places of interest were a regular institution, and these interests were readily tied to G's reading. Among the places thus visited were the zoo, botanical gardens, aquarium, navy yard, fleet, airport, museums, art galleries, Hall of Fame, numerous factories and industrial plants, fire department, public utilities, observatories. Plays and concerts were attended, and good taste in music was encouraged. Educational use was made of radio programs. G learned to play the violin and joined the school orchestra. At his own request he was given private instruction in Hebrew and made good progress. At an early age--7 or 8 years--G became interested in chemistry, and was provided with a chemical outfit for his own use. With this he busied himself a great deal, and he kept his classmates provided with ink of his own manufacture. He has collected both stamps and coins and also _Popular Science_ magazines. There is in the files a large collection of his remarks in childhood, recorded by his parents. They show early thoughtfulness, curiosity, and judicious discrimination.
