Keston and I looked at each other in amazement. The master machine was trying to hold back the mighty Glacier by the sheer power of its cohorts!


wild light sprang into Keston's eye—of admiration, of regret. "What a thing is this that I created!" he muttered. "If only—" I truly believe that for a moment he half desired to see his brain-child triumph.

The air was hideous with a thousand noises. The Glacier wall was cracking and splitting with the noise of thunderclaps; the machines were whirring and banging and crashing. It was a gallant effort!

But the towering ice wall was not to be denied. Forward, ever forward, it moved, pushing inexorably the struggling machines before it, piling them up high upon one another, grinding into powder the front ranks.

And to cap it all, the huge overhang, a thousand feet high, was swaying crazily and describing ever greater arcs.

"Look!" I screamed and flung up my arm. Great freight planes were flying wing-to-wing, head-on for the tottering crag—deliberately smashing into the topmost point.

"Trying to knock it back into equilibrium!" said Keston, eyes ablaze, dancing about insanely.

But the last suicidal push did not avail. With screams as of a thousand devils and deafening rending roars, the whole side of the Glacier seemed to lean over and fall in a great earth-shattering crescendo of noise.
