Plot

Laird Cunningham is a rich man who enjoys travelling to distant worlds in search of bizarre life forms. On the trip told in this story, Cunningham overhears the plotting of his two assistants to loot the ship. To avoid this, he forces a crash landing on an unnamed planet, sabotages the ship and escapes, leaving his assistants in the ship.

Cunningham goes exploring and finds that the planet is very strange and orbits one of the fiercest suns in the galaxy (Deneb

Deneb is the brightest star in the constellation Cygnus and one of the vertices of the Summer Triangle. It is the 19th brightest star in the night sky, with an apparent magnitude of 1.25. A blue-white supergiant, Deneb is also one of the most luminous nearby stars...

). The planet itself is quite similar to Earth's Moon, being airless and of a similar size, but due to the daily heating by its sun, the terrain is very different and appears strangely windswept. Cunningham also investigates the local life forms which include plants, herbivores and carnivores. He dissects a few of the animals and finds that they have liquid metal for blood and that their eyes are more like noses, in that their eyes function as pinhole cameras

 with respect to the local gas molecules, which in the near vacuum travel in essentially straight lines like light rays. Cunningham realises that the animals navigate mostly by smell, since the extremely bright, undiffused sunlight would hamper an optical sense.

Taking refuge in a cave, Cunningham watches his ship and his assistants as they attempt to repair it, welding up cracks in the ship's hull. However, they only work during the day and return to the inside of the ship at night. By night, Cunningham kills animals and collects their blood in grooves in the cave floor. The blood freezes in the cold of the night and he attaches the resulting small bars of metal to the remaining cracks in his ship's hull. The next morning, his assistants emerge to continue welding, which melts the bars of blood. The smell attracts many local predators, and Cunningham makes his way onto the ship in the commotion. Although the assistants easily fight off the alien animals, Cunningham locks them in the airlock as they attempt to return to the ship. He then sends out a distress call and sits back, waiting for help to arrive.
