JACK TENNISON sold his first short story to the old Youth’s Companion. ”The check,”he writes, “was fifteen dollars, and this created some commotion in Company I, Volunteer Infantry, 1898.” Since then his stories have brought him an O. Henry Memorial Prize; and one of his novels, The Day of Souls, a story of pre-earthquake San Francisco, was called by Damon Runyon “the best, truest thing ever written about the city that was.”
