“Salaam, Syyed!”

What was this? The whole of the immense vault was roaring and bellowing with sound. In waves it rolled, now running along the ground at their feet, now tossed on high as though escaping into outer air. “Salaam, salaam, salaam!” it replied in every conceivable tone and key, then roared along the cliffs again as in a peal of thunder, the whole accompanied by a mighty rattling. The noise was simply appalling.

Raynier, the sceptical, was more than startled. Not to put too line a point on it, he was just a little bit scared, though no manifestation of it escaped him. The horses of both, too, were backing and snorting, evincing a degree of terror not at all calculated to soothe the nerves of their riders. The suddenness of it all, the booming of the spectral voices here in the grisly depths, was rather startling.

He looked at his companion somewhat apprehensively, expecting to see her pale and shaking, perhaps hysterical. To his surprise she was laughing. His first thought even then was that this was a form of hysteria.

“Don’t you see?” she said.

“Don’t you see? Don’t you see?” boomed the vault around. “Don’t you see? Don’t you see?” shrieked and wailed the heights above. And then Raynier felt secretly more than a little ashamed of himself—for he did see.

As they were talking they had rounded a sudden bend in the defile, and the salute he had jocosely directed to the dead Syyed—if such a person had ever existed in fact—had been caught up by a most astounding echo, which, for no apparent reason, was given forth precisely at that spot. Still, it was not a little curious that they should have entered within its scope simultaneously with the utterance of the half-mocking words, which, mingling with the rattle of the horses’ hoofs upon the loose stones of the tangi, had produced the horrible din.

Now it was she who said in a whisper,—

“We had better not talk out loud or these horses will go quite mad. It is all I can do to stay on mine as it is.”

In fact the animals were in the wildest stage of snorting, trembling fear, and could hardly be persuaded to proceed at all. Their shying and plunging created a rattle which the echo reproduced and magnified as before. At length they quieted down.
