"My name is Maxwell Haskins..."
Storyline
Professor Mason Halloway has perfected a time machine, which he sets for 1000 years into the future. Upon arrival he finds a barren scorched earth, and believes he has miscalculated, arriving 1000 years in the past. Several humans appear, speaking in English, and Halloway explains his apparent error. In fact, it is the year 2952, and the group leader explains that the Roentgen ray, initially so beneficial in curing diseases, eventually built up in the atmosphere and destroyed the ecosystem.
