“Welcome!” exclaimed the Doctor in a loud whisper.

Welcome!

Welcome!

Welcome!

Instantly following the Doctor’s whisper, his utterance was repeated three distinct times in different parts of the cave. The effect was startling and weird.

“This I call ‘The Cave of Whispers,’” said Dr. Jaquet, in response to his companions’ inquiring looks. “See! You whisper and your words they come back to you!”

The Doctor then went on to explain that one of his objects in buying the land and fitting up the cave was to make a study of acoustics: a science comparatively undeveloped to this day. But the place had a peculiar charm for him apart from this, he declared.

The Professor and Mr. Kearns amused themselves for some time whispering various sentences, all of which were faithfully echoed back to them.

“And now,” said Dr. Jaquet, “you must be tired my friends. You shall yourselves rest and I shall give you tobacco to smoke which you will find fit for a Sultan.”

As he spoke, he arranged for them some rugs and cushions and produced a handsome Turkish Narghille, which he placed before them on the floor. This he proceeded to prime with a long-fibred, very pale-colored tobacco, and to each of them he handed an amber stem.
