individuality, so as to utilize unhampered their skill with medicine
and scalpel.

They were clad in soft yellow robes and seated at ease at one end of a
room crowded with a bewildering profusion of gauges, machines,
instruments, screens, wheels, levers, and other nameless controlling
devices. They did not show surprise at the huge clumsy figure that
stood suddenly before them, a raygun in one hand. Like the coolies,
their clean-cut features did not change under emotion. All they did
was rise silently, as one, gazing at the adventurer out of blank eyes,
saying nothing, and making no other move.

Carse tried simple measures in dealing with them. His voice gentle yet

form that was Friday standing motionless by the small port-lock, and,
an equal distance away, moving around one of the out-buildings,
another similar figure. He spoke by radio.

"Find any, Ban?"

Cheerful words came humming back.

"Only one coolie, Carse. Had no trouble after I disarmed him. He's now
locked inside a room in this building. Safe place for prisoners."

"Good," said Carse. "You can see I've got four men--white men. I
believe they're unarmed and quite harmless, but I want you to take
them, search them and put them away in that room too."

"Coming!"

The distant form rose lightly, skimmed low ov
