"Had enough?" Planter challenged.

Disbro was crawling on the floor, trying to grab the pistol. Planter sprang in, stamped on Disbro's knuckles. Disbro had only the strength and breath for one scream, and collapsed.

Abruptly Skygors entered, Skygors with hard eyes and leveled weapons. "What," demanded one, "is this?"

Disbro, helped to his shaky feet, pointed to Planter. "He—he—refused," he managed to wheeze out.

Disbro nodded, and Planter felt a sudden rush of joy. They would drive him forth, as they used to drive forth unprofitable female slaves. And he would find the Nest again, and Mara.

He was being herded along a passage, up stairs. The Skygors who guarded him kept their weapons close against his ribs. "No escape," they promised him balefully.

He wondered at that, but only a little. Now they had brought him out upon an open, railed bridge between two buildings. Below was water, above the thick Venusian mist. "Jump," a Skygor bade him.

"I need no second chance," Planter replied, breezily, and dived in.

He still wore the scanty costume of a slave, and it allowed him to strike out easily for the edge of the pool. Behind him the Skygors were discussing him, but in their own guttural tongue which he could not understand. As he swam, he studied the city beneath the water.

He meant to come back and assail that city some time, and there must be worthwhile secrets to note. For instance, he was now aware that this pool was artificial—he made out the sluices and gates of a large dam. To one side was a spacious submarine chamber that must be the clockwork-jammed cellar where his erstwhile companions, the slaves, worked.
