"Well," said MacNabb; "and was Robert on your right, or on your left?"

"On my left. I remember that his poncho flapped in my face."

"And where were you situated in reference to us?"

"On the left also."

"Then Robert could have disappeared only on this side," said the major, turning towards the mountain, and pointing to the right. "And also considering the time that has elapsed since his disappearance, the child must have fallen at a high part of the mountain. There we must search, and, by taking different ways, we shall find him."

Not a word more was said. The six men, scaling the declivities of the mountain, stationed themselves at different heights along the ridge, and began their search. They kept always to the right of their line of descent, sounding the smallest fissures, descending to the bottom of precipices half filled with fragments of the mass; and more than one came forth with his garments in shreds, his feet and hands lacerated, at the peril of his life.

A SLEEPLESS NIGHT.

All this portion of the Andes, except a few inaccessible plateaus, was carefully explored for many hours without one of these brave men thinking of rest. But it was a vain search. The child had not only found death in the mountains, but also a tomb, the stone of which, made of some enormous rock, was forever closed over him.

Towards noon Glenarvan and his companions, bruised and exhausted, found themselves again in the valley. The former was a prey to the most violent grief. He scarcely spoke, and from his lips issued only these words, broken by sighs,—"I will not go; I will not go!"

Each understood this determination, and respected it.
