Tomahawk #63

A mysterious flying machine starts stealing furs from frontiersmen using incredible vacuum power and wind generators, and later the Mohawk tribe is attacked by a device that can project either freeze rays or heat rays. A group of ne'er-do-wells have stumbled on the remains of a crashed space craft and are slowly, but surely, figuring out how to work the devices they find inside. So, it's up to Tomahawk and the Indians to work together to destroy the machines.
