Yet the strange thing was that not a bird was to be seen. At that hour the ordinary feathered inhabitants of the island were quietly nestling among the branches preparatory to making a final selection of the night's resting-place. None of them would stir unless actually disturbed.

Iris drew near to the sailor. Involuntarily she caught his arm. He stepped a half-pace in front of her to ward off any danger that might be heralded by this new and uncanny phenomenon. Together they strained their eyes in the direction of the approaching sound, but apparently their sight was bewitched; as nothing whatever was visible.

"Oh, what is it?" wailed Iris, who now clung to Jenks in a state of great apprehension.

The clucking noise came nearer, passed them within a yard, and was already some distance away towards the reef when the sailor burst into a hearty laugh, none the less genuine because of the relief it gave to his bewildered senses.

Reassured, but still white with fear, Iris cried: "Do speak, please, Mr. Jenks. What was it?"

"A beetle!" he managed to gasp.

"A beetle?"

"Yes, a small, insignificant-looking fellow, too—so small that I did not see him until he was almost out of range. He has the loudest voice for his size in the whole of creation. A man able to shout on the same scale could easily make himself heard for twenty miles."

"Then I do not like such beetles; I always hated them, but this latest variety is positively detestable. Such nasty things ought to be kept in zoological gardens, and not turned loose. Moreover, my tea will be boiled into spinach."

Nevertheless, the tea, though minus sugar or milk, was grateful enough and particularly acceptable to the sailor, who entertained Iris with a disquisition on the many virtues of that marvelous beverage. Curiously enough, the lifting of the veil upon the man's earlier history made these two much better friends. With more complete acquaintance there was far less tendency towards certain passages which, under ordinary conditions, could be construed as nothing else than downright flirtation.
