NON-FICTION: Ginger

SAWDUST AND SOLITUDE—Lucia Zora—Little, Brown ($2.50). Sensational circus performer, 20 years ago, Lucia Zora was the first woman to tame tigers, train "the big herd" to their ponderous tricks, dose colic-stricken elephants with paregoric or Jamaica ginger. But she deserted the arena to indulge her second hardy ambition: pioneer prospecting. At a Colorado altitude of 8,000 feet, she and her husband (ex-menagerie superintendent) struggled six years with reluctant agriculture, mountain blizzards, and "Cabin Fever" which is a loneliness verging on hysterical insanity. For sacrificing the thrill of "sawdust" to the good citizenship of "solitude" her reward is a prosperous ranch, complete with radio.
