Captain Zoss had gone on ahead with the Indians and just before midnight he came back with a warning to watch out for several splits, or crevasses, in the glaciers they were now traversing.
"Salmon Head says he heard a report of several new ones just before starting, and these are as yet unmarked," he said.
"We'll be as careful as we can," said Dr. Barwaithe. "We can do no more."
They now passed over a broad plain of snow where the mists hung more thickly than ever. They had almost reached the centre of the plain when a loud cry from the Indians ahead caused them to halt.
"What can be the meaning of that?" questioned Earl. "Can they be in trouble?"
Presently, from among the mists appeared the form of one of the Indian carriers, without his bundle. He soon explained in broken English that he had been sent back by Salmon Head to warn them of a split in the ice field just ahead. One of the Indian women had slipped in, and it was by mere good fortune that some of the men had rescued her.
This Indian remained with them until the crack was reached, where he resumed his pack and went on. The opening was an irregular one, from four to eight feet wide and of unfathomable depth. Fortunately the sides were well defined and firm, so they had small trouble in leaping across.
