If the second lieutenant of the Chatauqua had received the bolt from a thunder cloud he could not have been more astonished. He started back, turned pale, and quivered with emotion.

"Who?" demanded he, with a tremendous effort to recover his self-possession.

"Do you think, Mr. Pillgrim, that I am a little lamb, that can be led round with a silken string?" replied Somers, with energy. "You are my superior officer, and as such I will respect and obey you until--until--"

"Until what?"

"Until the day of reckoning comes. When you stand up in my presence and charge me with being a traitor to my country, you had better remember that such charges, like chickens, will go home to roost."

"I was not brought up in a barn yard, Mr. Somers, and such comparisons are beyond my comprehension."

"Wherever you were brought up, I think my language is plain enough to be understood by a person of your intelligence."

Perhaps it was fortunate for both parties that a knock at the state-room door disturbed the conference at this exciting moment. Somers opened the door.

"Mr. Hackleford desires to see Mr. Somers on deck," said a midshipman.

"Excuse me for a few moments, Mr. Pillgrim," said Somers, as he closed his desk and locked it.

"Certainly, sir; but I should be happy to see you when you are disengaged. I will remain here if you please."

"I will join you as soon as I can."

It was warm below, and both Pillgrim and Somers had thrown off their coats, and laid them on the bed. Somers slipped on his own, as he supposed, and hastened on deck to meet the first lieutenant. The garment seemed rather large for him, and there were several papers in the breast pocket which did not belong to him. Then he was aware that he had taken the second lieutenant's coat instead of his own.

Mr. Hackleford wished to obtain some information from him in regard to one of the petty officers, and when Somers had answered the questions he went below again. The papers in the pocket of Pillgrim's coat seemed to burn his fingers when he touched them. The owner was a traitor, and perhaps these doc.u.ments might contain valuable intelligence. Under ordinary circ.u.mstances it would have been the height of perfidy to look at one of them; but, in the present instance, he felt justified in glancing at them. The state-room of the second a.s.sistant engineers was open and lighted, but neither of these officers was there. Stepping into the room, he opened the papers and glanced at their contents. Only one of them contained anything of importance. This was a note from a person who signed himself simply "Irvine," but it was in the handwriting of Langdon. The only clause in the epistle that was intelligible to Somers was this: "Have just heard from B----. The Ben Nevis, he says, will make Wilmington after leaving St. John. Plenty of guns there. She will sail July 4."

Whether "B----" meant Boston or some person's name, Somers could not determine; but the fact in regard to the Ben Nevis was of the utmost consequence. Hastily folding up the note, he returned the package of papers to the pocket where he had found them. Taking off the coat as he entered the ward-room, he went into the state-room, where Mr. Pillgrim was still waiting for him, with the garment on his arm. He threw it upon the bed as he entered, and his companion was not even aware of the mistake which had been made.

"Mr. Somers, you were making some grave charges against me when you were called away," said the lieutenant.

"Not half so grave as those you made against me," replied Somers.

"Those can be proved."

"I made no charges. I only mentioned the name of your friend Langdon."

"I don't know him," added Pillgrim, doggedly.

"I beg your pardon, as you did mine, just now."

"Which means that you doubt my word."

"As you did mine."

"Somers, I am not to be trifled with," said Pillgrim, sternly.

"Neither am I."

"Be cautious, or I will denounce you to the captain at once," added the lieutenant, in low and threatening tones.

"Proceed, and then I shall be at liberty to take the next step."

"What's that?"

"Do you think I intend to show you my hand?" said Somers, with a meaning smile.

Pillgrim bit his lip with vexation. He seemed to be completely cornered.

He evidently believed that his companion knew more than "the law allows."

"Mr. Pillgrim, I am no traitor; you know this as well as I do. Whatever papers I took from your friend Langdon, _alias_ Wynkoop, were taken with a view to serve my country."

"You signed the oath of allegiance he offered you."

"It is false!" replied Somers, angrily.

"Be calm, Mr. Somers. I am no hypocrite, as you are," added Pillgrim. "I have heard that you have a talent for overhearing other people's conversation."

"In the service of my country I am willing to do even this," said Somers, indignantly.

"No matter about that. You have hinted that I am a traitor."

"If the hint is not sufficient, I declare that such is the fact."

Somers was roused to a high pitch of excitement, and he was not as prudent as he was wont to be. He was not playing a part now; he was talking and acting as he wanted to talk and act. He was calling treason and treachery by their right names.

"Explain, Mr. Somers," said Pillgrim, who grew cooler as his companion became hotter.

"You are in league with the enemies of your country. You and others have just started a steamer for St. John, which you intend to fit out as a Confederate cruiser--the Ben Nevis, of which you and your fellow-conspirators did me the honor to give me the command."

Pillgrim smiled blandly.

"And you accepted the command?"

"For a purpose, I did."

"You have not explained why you connect me with this affair. You spoke of some one whom you call Langdon. I don't know him."

"You--do!"

"Prove it."

"He addresses a note to you, calling you 'my dear Pillgrim,' and signs himself, familiarly, 'Langdon.'"

"Then you have been reading my letters--have you?"

"It was addressed to me, and put in my box at the hotel."
