Glancing down hill with smarting eyes, she thought the slope, which, from the top, had seemed to fall evenly to the dale, was also inclined towards the crag.

She could not see much of the latter, but there was a fringe of dark rock where the white declivity broke off.
"Aren't we getting too near ?" she shouted.
"Nearer than I thought," Thorn gasped.

"Not sure I can swing the sledge.
Can you get back and help ?" Grace braced herself.

Alan's nerve was good, but there was a disturbed note in his voice; besides he would not have asked her help unless it was needed.

Wriggling back cautiously, she got level with Thorn, although there was not much room for them side by side.
