recall hearing the ping of Larry's bullet against the mailed body of the Robot. At that it crouched, and from it leaped a dull red-black beam of light. I heard Mary scream. She had not fled but was clinging to me. I cast her off.

"Run! Get back! Get away!" I cried.

Larry shouted, as we all stood bathed in the dull light from the Robot:

"Look out! It sees us!"

He fired again, into the light—and murmured, "Why—why—"

A great surprise and terror was in his tone. Beside me, with half-leveled revolver, Alten stood transfixed. And he too was muttering something.

All this happened in an instant. And there I was aware that I was trying to get my rifle up for firing again; but I could not. My arms stiffened. I tried to take a step, tried to move a foot, but could not. I was rooted there; held, as though by some giant magnet, to the ground!

This horrible dull-red light! It was cold—a frigid, paralyzing blast. The blood ran like cold water in my veins. My feet were heavy with the weight of my body pressing them down.
