THE SUN ALSO RISES—Ernest Hemingway—Scribner ($2). A lot of people expected a big novel from burly young Author Hemingway. His short work (In Ou Time, 1925) bit deeply into life. He said things naturally, calmly tersely, accurately. He wrote only; about things he had experienced mostly outdoors, as a doctor's son in northern Michigan and as a self-possessed young tramp in Europe. Philosophically his implication was: "Life's great. Don't let it rattle you."
