"I am afraid we are too late, and that the steamer has sailed on her mission of destruction," said he, almost overcome by the discovery. "She was here last night, and was watched till this morning. She has already cleared, bound to Wilmington, Delaware, with a cargo of old iron."

"Do you know her name, Captain Passford?" asked the commander of the Chateaugay.

"She was a screw steamer of about six hundred tons, and was called the Ionian, but she is American."

It was useless to remain there any longer, for the steamer certainly was not there. Captain Passford hailed a passing-tug-boat, and they were taken on board. The master of the boat was instructed to steam down the East River, and the party examined every steamer at anchor or under way. The tug had nearly reached the Battery before the leader of the trio saw any vessel that looked like the Ionian. The tug went around this craft, for she resembled the one which had been in the dock, and the name indicated was found on her stern.

"I breathe easier, for I was afraid she had given us the slip," said Captain Passford. "She is evidently all ready to sail."

"The Chateaugay is in commission, and ready to sail at a moment's notice," added her commander.

"But you are not ready to leave at once, Christy," suggested Captain Passford, with some anxiety in his expression.

"Yes, I am, father; I put my valises on board yesterday, and when mother and Florry went down to Mr. Pembroke's I bade them both good-by, for after I have waited so long for my passage, I felt that the call would come in a hurry," replied Christy. "I am all ready to go on board of the Chateaugay at this moment."

"And so am I," added Captain Chantor.

"But I am not ready with your orders in full, though they are duly signed," said Captain Passford. "I will put you on shore at the foot of Atlantic Avenue in Brooklyn, Captain Chantor, and you will hasten to your ship, get up steam, and move down to this vicinity. I will put my son on board as soon as I can have your papers completed."
