**Voyage of the Marathon** Even at the time when space ships were making regular voyages across the universe, the MARATHON was a remarkable craft. Powered by the Flettner system, its speed was so great that for the first time exploration of the outer galaxies was made possible. *Men, Martians and Machines* describes some of the great voyages made by the MARATHON. There was, for example, the planet which was solely inhabited by machines — survivors, perhaps, from a civilization in which the first machine-makers had perished. On another planet, the inhabitants had developed the power of hypnotism to a fantastic degree, so that the observer saw only what he was willed to see. *Men, Martians and Machines* is Eric Frank Russell at his very best.
