"Are we birds, that we can fly?" said Chow, with astonishment.

When they had proceeded some distance through the opening, they came to another and narrower cleft, cut out of its sides, to pass through which they were compelled to unharness the mules and camel, when they entered a wide, open space, like a courtyard.

"Even now we want wings, my brother," said Chow, shuddering, as he gazed upward at the great height.

"Our wings are here," said the man, turning aside what appeared to be a huge block of rock, but was only an ingenious imitation, when before them there was a flight of steps, steep, and so narrow, that they looked as if the ascent would squeeze a fat man a foot taller.

However, pleased at the discovery of such a place of refuge, they did not stop to examine it, but passed onward; the princess first, and the other women followed by the men, who carried articles of food, fuel, or raiment with them. Having reached the uppermost step, they crept through a hole large enough only for one person, and found themselves in one large room, the roof of which was indeed the summit of the rock. In the walls were small loopholes, from which could be seen many miles of country; there was also a large space in one side for a fire, which was immediately made use of by Chow, who had carried the fuel. Then the guide was sent to fetch other matters, after which they all sat down upon their mats, and partook of hot tea and rice cakes.

"Truly this is a wonderful place," said Nicholas, who, although he knew that places of refuge were common in all the frontier provinces, had no notion of their real strength and security.

"See," said the man, pointing to some huge stones near the entrance, and some heavy bars of iron hanging upon the walls, "should the dogs discover our retreat, they may be crushed as small as tea-dust."

"Truly they could but starve us out."

"Not so, noble youth," said the man pointing to a massive slab of rock; and adding, "This is a door and leads to another part of the mountain."

"Truly our ancestors were wise."
