cacophonous background for the cries of maddened Titanians, the screech of roller motors roaring into action, the moans of injured and dying natives. Then— Then Colossus burst from the womb of the hampering earth! Rose to stand upright in the prison he had outgrown. He shook himself, and detritus scattered about the terrified watchers. He raised a great palm, and with demoniac deliberation brought it squarely down upon a tiny band of huddled and terrified natives. When he lifted his palm again ... it dripped redly! Rocky thrust the fumbling Grossman from the controls. "Move over!
