Esther Kellner's girlhood appears rather to have resembled a boyhood, and yet, judging from her writing after years of wifehood and motherhood, she could scarcely be a more feminine person. The most cherished companion of her youth was ""Old Bill,"" a rustic friend of her great-uncle. From her home in an Indiana city. she was taken visiting to Bill's farm, and he delighted in sharing with her the scientific facts and sporting skills of woods lore and guncraft, sharpening her powers of observation all the while they hunted and explored together. The fox squirrel is also a central character in her life. Bill had often praised the intelligence of the little creature, and adult Esther -- raising the litter of a young female that had disappeared -- had reason to remember Bill's affection and knowledge of their ways. When the squirrels fell ill, she and her husband discovered the abysmal lack of knowledge humans (even scientists) have of wild animals, and so she has put into this book her discoveries of interesting ata potentially useful for anyone who keeps a normally wild small animal as a pet. Though emphatically opposed to careless hunting, Mrs. Kellner scores her point without being officious or maudlin. Her story is told with skill and makes pleasant family-type reading. She is also the author of several books on Biblical themes.
