“That’s the same size as mine,” said Mr Preddle, quietly. “I’m afraid those of yours would not fit.”

“Fit? No!” cried Mr Frewen, impatiently. “They would be absolutely useless.”

“Yes, sir, enough for about three days, without counting anything our passenger friends have in the way of private stores—preserved meat, delicacies, or the like.”

“Yes, but the water?” said the captain, naming the grave necessity of life in that hot climate.

“I must frankly say a very short supply, sir.”
