Their pursuers paused a moment on gaining the brow to get their wind, and then followed; but as soon as the ground again became too steep to allow of rapid movement, Roger turned and, betaking himself to his bow and arrows, speedily checked the pursuit; the Aztecs being unable to stand against these terrible weapons, whose force and accuracy seemed to them supernatural.
The sight, too, of the heap of their comrades lying on the slope had greatly cooled their courage.

Their officers had all fallen under Roger's arrows, together with most of their bravest comrades; and although the rest still continued the pursuit, it was at a distance that showed that they had no intention, whatever, of closing again.
Paying no further heed to them, Roger and his companion now directed their whole attention to the work of climbing.

At times they came on perpendicular precipices, and had to make long detours to surmount them.

After some hours' labor they reached the snow.
They were now near a shoulder between two lofty peaks, and after an hour's climbing stood on its crest.

The Aztecs were now mere spots, far behind them.
"They will be an hour before they are here," Roger said.
