“Nobody said a word, because everybody was fast asleep, I presume,” said Alfred; “I heard nothing.”

“It was like the sound of cart-wheels at a distance, with whistling and hissing,” said Mary.

“I think I can explain it to you, as I was up during the night, Miss Percival,” said Captain Sinclair. “It is a noise you must expect every night during the summer season; but one to which you will soon be accustomed.”

“Why, what was it?”

“Frogs,—nothing more; except, indeed, the hissing, which, I believe, is made by the lizards. They will serenade you every night. I only hope you will not be disturbed by anything more dangerous.”

“Is it possible that such small creatures can make such a din?”

“Yes, when thousands join in the concert; I may say millions.”

“Well, I thank you for the explanation, Captain Sinclair, as it has been some relief to my mind.”

“Surely, he hardly expects us to quit the place to please him?”
