"There's a little scrambling here," said Nightspore. "We are both used to climbing, and there is not much in it."He indicated a narrow ledge, winding along the face of the precipice a few yards beneath where they were standing. It averaged from fifteen to thirty inches in width. Without waiting for Maskull's consent to the undertaking, he instantly swung himself down and started walking along this ledge at a rapid pace. Maskull, seeing that there was no help for it, followed him. The shelf did not extend for above a quarter of a mile, but its passage was somewhat unnerving; there was a sheer drop to the sea, four hundred feet below. In a few places they had to sidle along without placing one foot before another. The sound of the breakers came up to them in a low, threatening roar.
Upon rounding a corner, the ledge broadened out into a fair - sized platform of rock and came to a sudden end. A narrow inlet of the sea separated them from the continuation of the cliffs beyond.
"As we can't get any further," said Maskull, "I presume this is your Gap of Sorgie?""Yes," answered his friend, first dropping on his knees and then lying at full length, face downward. He drew his head and shoulders over the edge and began to stare straight down at the water.
