A yard below him was a ledge of rock, some two feet wide.

It was level, and had deep grooves cut, at regular intervals, across it.

He had no doubt that the roof of the outside temple had started from this point; and that the grooves were made for the ends of massive rafters, of teak or stone.

At that time the passage to the chamber that he had left was, doubtless, used for an exit on to the flat roof.
Stepping on to the ledge, he called Meinik to him.
"Now, Meinik," he said, "we will follow this ledge.

There may be some way up from it." Walking with a good deal of care, Stanley made his way along to a point where the ledge stopped, abruptly.
