New York: Macmillan, 1925. First edition. Translated from the Czech by Lawrence Hyde. The story of an engineer who discovers "Krakatit" -- an explosive powerful enough to destroy the world. Bright and nearly fine with barest wear and one small stain to page fore edge. In dust jacket with corners clipped but "$2.50" price still present, as usually seen. Jacket is lightly chipped, has two internal tape repairs (thin strip of paper tape and small piece of clear tape), and is somewhat skinned on rear panel but otherwise bright and very good.
