work, furtive beetles and tiny insects burrowed below the reeking body to attack the highly scented flesh from a fresh angle.

Each working independently of the others, they commonly appeared in the order of the delicacy of the sense which could lead them to a source of food, though accident could and sometimes did afford one group of workers in putrescence an advantage over the others.

Thus, sometimes a blue-bottle anticipated even the eager ants, and again the very flesh-flies dropped their squirming offspring upon a limp form that was already being undermined by white-bellied things working in the darkness below the body.

Burl grimaced at the busy ants and buzzing flies, and disappeared into the mushroom forest. Here for a long time he moved cautiously and silently through the aisles of tangled stalks and the spongy, round heads of the fungoids. Now and then he saw one of the red toadstools, and made a wide detour around it. Twice they burst within his sight, circumscribed as his vision was by the toadstools among which he was traveling.

Each time he ran hastily to put as much distance as possible between himself and the deadly red dust. He traveled for an hour or more, looking constantly for familiar landmarks that might guide him to his tribe. He knew that if he came upon any place he had seen while with his tribe he could follow the path they had traveled and in time rejoin them.

For many hours he went on, alert for signs of danger. He was quite ignorant of the fact that there were such things as points of the compass, and though he had a distinct notion that he was not moving in a straight line, he did not realize that he was actually moving in a colossal half-circle. After walking steadily for nearly four hours he was no more than three miles in a direct line from his starting-point. As it happened, his uncertainty of direction was fortunate.

The night before the tribe had been feeding happily upon one of the immense edible mushrooms, when they heard Burl's abruptly changing cry. It had begun as a shout of triumph, and ended as a scream of fear. Then they heard hurried wing-beats as a creature rose into the air in a scurry of desperation. The throbbing of huge wings ended in a heavy fall, followed by another flight.

Velvety darkness masked the sky, and the tribesmen could only stare off into the blackness, where their leader had vanished, and begin to tremble, wondering what they should do in a
