"At last," cried Shandon, "we shall know the secret."

With a quick hand he tore the envelope and read as follows:

"COMMANDER,—The captain of the Forward is pleased with the coolness, skill, and courage that your men, your officers, and yourself have shown on the late occasions, and begs you to give evidence of his gratitude to the crew.

"Have the goodness to take a northerly direction towards Melville Bay, and from thence try and penetrate into Smith's Straits.

"THE CAPTAIN OF THE Forward,
"K. Z."

"Monday, April 30th,

"Abreast of Cape Walsingham."

"Is that all?" cried the doctor.

"That's all," replied Shandon, and the letter fell from his hands.

"Well," said Wall, "this chimerical captain doesn't even mention coming on board, so I conclude that he never will come."
