There is apparently no limit to the market for horse books -- and this is a sure candidate for popularity. It meets one very vital need- a practical, down to earth book at the easy reading level. The story interest is slim. Lance is six; he was ""born on a horse"" but had no horse of his own. But he was promised one when he could prove his responsibility -- and when he was seven. This tells, step by step, what he learned about horses, about riding, and how he proved his good sense in an emergency. The vocabulary, while special, will be one that young horsemen will find familiar, even at second grade level. The Wesley Dennis pictures show boy and horse in not too prettied-up guise.
