One man was strumming a mandolin already, and two or three began to sing.

But Ned saw sentinels walking among the tumuli and along the Calle de los Muertos which led from the Citadel to the southern front of the Pyramid of the Moon.

He was very glad now that he had sought this lofty refuge, and he renewed his climb.
As he drew himself upon another terrace he saw before him a dark opening into the very mass of the pyramid, which was built either of brick or of stone, he could not tell which.

He thought once of creeping in and of hiding there, but after taking a couple of steps into the dark he drew back.

He was afraid of plunging into some well and he continued the ascent.
