The oars were silently dipped into the water, all three men listening intently at the time, with their faces turned towards the reef.

Suddenly on the other side of the surf they distinctly heard a hustling, rushing, fearful noise, accompanied by a low but startling cry, as of some creature in dire distress.

Nearer and nearer with almost the speed of a rocket it seemed to come, then ceased entirely, but at the same time, betwixt them and the moonlight, at least fifteen feet high in the air, they beheld an apparition that, in such a situation, was enough to frighten the boldest man that ever lived.

It was simply the great black head and two fins—no more apparently—of a monster fish with goggle eyes and open mouth. It took the water near the boat, raising a wave of breaking water that all but swamped it, and was seen no more.

When Fred looked up he saw both Quambo and Frank crouched down almost in the bottom of the boat, though it was half full of water.

Frank was the first to speak.

"Mercy on us!" he cried. "What was that?"

"Favaroo! favaroo!" said Quambo. "That is favaroo." His voice trembled as he spoke. "A devil fish; de evil spirit bite all away his body one day, and now he go everywhere trying to find he."

"Oh!" cried Fred, laughing now, "that is really the awful creature that little Kashie took for 'de debbil that hadn't got nuffin on but his head.' It is a sunfish as big as an elephant."

"Well," said Frank, "I've heard of such visitations, but I didn't know the beast could jump like that before. Let us bail out the boat. Why she is half swamped!"
