The heat of the ride had gone, and I remember feeling my shirt hang clammily on my shoulders.
Suddenly a hand was laid on my breast, and a voice demanded, 'The word ?' 'Immanuel,' I said hoarsely.
Then unseen hands took both my arms, and I was led farther into the darkness.

My hopes revived for a second.

The password had proved true, and at any rate I should enter the cave.
In the darkness I could see nothing, but I judged that we stopped before the stone slab which, as I remembered, filled the extreme end of the gorge.

My guide did something with the right-hand wall, and I felt myself being drawn into a kind of passage.

It was so narrow that two could not go abreast, and so low that the creepers above scraped my hair.
