"No Now Frontiers," by John Dun; (The RoycroCtcra). In this book, John Dun, associate, editor of tho Toledo (Ohio) Times, has gathered together eleven talcs o£ adventure Inspired, he says, "by Arizona sunshine." West ho went In search of new frontiers, but found them not. Rather In Arizona and other point? west his "visionary frontiers vanished," and ho found people doing the same things and thinking tho same thcniglits as in the east. "Centuries or sections don't change human nature," ho says. "Manmade problems go on forever, ns the little brook, In spite of time or geography." Nevertheless, he found his share of adventure, including a holdup In Hollywood in which ho offered to split the contents of his purse with the thief and surprisingly was taken up on the deal. Then there was tho tangle with a mountain lion In Bloxton, Arizona ghost town, which ho attributes to another, but which circumstantially reads like a personal adventure. Not to mention the time ho set his mule on fire while going down the Grand Canyon.
