displayed voluntary movement, but they seemed to have no respiratory or digestive organs. They were completely anomalous.

The grunion ran again that night, and Gene and Marge stayed down to help the laboratory assistants gather several hundred of the strange new objects for further study. They were so numerous that they were swamping the fish, and the crowds at the beach began to grumble that their sport was being spoiled.

Next night the grunion stopped running—but the little doughnuts didn't. They never stopped. They came in by hundreds of thousands every night, and those which nobody gathered wriggled their way over the land until some of them even turned up on the highways (where a lot of them were smashed by automobiles), on the streets and sidewalks of La Jolla, and as far north as Oceanside and as far south as downtown San Diego itself.

The things were becoming a pest. There were indignant letters to the papers, and editorials were written calling on the authorities to do something. Just what to do, nobody knew; the only way to kill the circular little objects from the sea seemed to be to crush them—and they were too abundant for that to be very effective.

Meanwhile, the laboratory kept studying them.

Marge and Gene were interested enough to come down again the next weekend to find out what, if anything, had been discovered. Not much had: but one of the biochemists at the laboratory casually mentioned that chemically the straw-colored circles seemed to be almost pure protein, with some carbohydrates and fats, and that apparently they contained all the essential vitamins.

College student that he was, Gene Towanda immediately swallowed one of the wriggling things down whole, as a joke.

It tickled a little, but that wasn't what caused the delighted amazement on his face.

"Gosh!" he exclaimed. "It's delicious!"

He swallowed another handful.

That was the beginning of the great margene industry.

It was an astute reporter, getting a feature story on the sensational new food find, who gave the creatures their name, in honor of the boy and girl who had first brought the things to the attention of the scientists. He dubbed them margenes, and margenes they remained.
