"Let's make haste and descend!" cried our hero. "My chest, where the fellow struck me, is getting stiff up here in this rare air."
Most haste less speed.
They had reached within twenty feet of the level portion of the berg when our hero slipped.
His arm could not bear his weight, and he half fell, half slid rapidly to the bottom of the peak.
"Are you much hurt, old fellow?" exclaimed Jack, as soon as he could reach his friend's side.
"Only bruised, I think. Just help me up."
When assisted to his feet it was evident that Bob had twisted his ankle, or slightly strained it.
"Misfortunes never come alone," he said, with a laugh. "We must get on.
If I find the descent difficult, you must help me."
A stream of water from the melting of the ice on the peak ran along in a little channel it had worn, to where it came to the ravine.
Here it fell over in a cascade, and divided, one part, now joined by other trickling streams, descended the gorge into the sea, the other flowing into the mouth of an ice cavern.
