Bart bent over him, breathing hard, trying to get his breath back. The hail was still pelting down, showing no signs of lessening. About five feet away, one of the dark gaps in the cliff showed wide and menacing, but at least, Bart thought, the hail couldn't come in there. He stooped and got hold of Ringg again. A pain like fire went through the wrist he had smashed against the rock. He set his teeth, wondering if it had broken. The effort made him see stars, but he managed somehow to hoist Ringg up again and haul him through the pelting hail toward the yawning gap. It darkened around them, and, blessedly, the battering, bruising hail could not reach them. Only an occasional light splinter of ice blew with the bitter wind into the mouth of the cave. Bart laid Ringg down on the floor, under the shelter of the rock ceiling. He knelt beside him, and spoke his name, but Ringg just moaned. His forehead was covered with blood. Bart took one of the paper napkins from the lunch sack and carefully wiped some of it away. His stomach turned at the deep, ugly cut, which immediately started oozing fresh blood. He pressed the edges of the cut together with the napkin, wondering helplessly how much blood Ringg could lose without danger, and if he had concussion. If he tried to go back to the ship and fetch the medic for Ringg, he'd be struck by hail himself. From where he stood, it seemed that the hailstones were getting bigger by the minute. Ringg moaned, but when Bart knelt beside him again he did not answer. Bart could hear only the rushing of wind, the noise of the splattering hail and a sound of water somewhere--_or was that a rustle of scales, a dragging of strange feet?_ He looked through the darkness into the depths of the cave, his hand on his shock-beam. He was afraid to turn his back on it. _This is nonsense,_ he told himself firmly, _I'll just walk back there and see what there is._ At his belt he had the small flashlamp, excessively bright, that was, like the energon-beam shocker, a part of regulation equipment. He took it out, shining it on the back wall of the cave; then drew a long breath of startlement and for a moment forgot Ringg and his own pain. For the back wall of the cave was an exquisite fall of crystal! Minerals glowed there, giant crystals, like jewels, crusted with strange lichen-like growths and colors. There were pale blues and greens and, shimmering among them, a strangely colored crystalline mineral that he had never seen before. It was blue--_No_, Bart thought, _that's just the light, it's more like red--no, it can't be like_ both _of them at once, and it isn't really like either. In this light--_ Ringg moaned, and Bart, glancing round, saw that he was struggling to sit up. He ran back to him, dropping to his knees at Ringg's side. "It's all right, Ringg, lie still. We're under cover now."
