captain passford looked over his papers for a moment; but it was soon evident from his manner that he had secrets which he would not intrust even to his son, unless it was necessary to do so. he seemed to be armed with documentary evidence upon which to act, but he did not read any of his papers, and soon returned them to his pocket.

"the american goods of which i speak are certain pieces of machinery to be used in the manufacture of arms," continued the captain. "they cannot be obtained in england, and the traitors have decided to send them direct, rather than across the ocean in the first instance. these will form the principal and most important part of the cargo of a steamer now loaded, though she will carry other goods, such as the enemy need most at the present time."

27 "i did not suppose any americans were wicked enough to engage in such an enterprise for the sake of making money," said christy indignantly.

"the steamer of which you speak is already loaded, is she?" asked captain chantor.

"she is; and now i wish both of you to go with me, and i will point out the vessel to you, and you must mark her so well that you can identify her when occasion requires."

the trio left the house and took the train together. they went to new york, and in an out-of-the-way locality they went down to a wharf; but there was no steamer or vessel of any kind there, and the pier was falling to pieces from decay. captain passford stopped short, and seemed to be confounded when he found the dock was not occupied.

"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.

28 "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 29 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."

the order necessary to carry out this procedure was given to the captain of the tug, and the commander of the chateaugay was landed at the place indicated. the tug started for the other side of the river.

"it seems to me this is very strange business, father," said christy, as he and his father seated themselves at the stern of the boat.

"traitors do not work in the daylight, my son, as you have learned before this time," replied captain passford.

30 "if you know the men who are engaged in supplying the enemy with machinery, why do you not have them arrested and put in fort lafayette?" asked christy, in a very low tone, after he had assured himself that no person was within possible hearing distance. "it looks as though the case might be settled here, without going to sea to do it."

"we have not sufficient evidence to convict them; and to make arrests without the means of conviction would be worse than doing nothing. the ionian has cleared for wilmington with a cargo of old iron. everything looks regular in regard to her, and i have no doubt there is some party who would claim the castings if occasion required. the first thing to be ascertained is whether or not the steamer goes to wilmington."

"then we can make short work of her."

"my information in regard to this treason comes from warnock—you know who he is?"

"captain barnes," replied christy promptly, for the names of all the agents of his father in england and scotland had been given to him on a former occasion, when the information received from one of the three had resulted in the capture of the scotian and the arran.

31 "barnes is a very shrewd man. he does not inform me yet in what manner he obtained the information that the ovidio was to carry this machinery from nassau into a rebel port; but i shall get it later in a letter. he gave me the name of the party who was to furnish the machinery; and one of his agents obtained this from the direction of a letter to new york. i placed four skilful detectives around this man, who stands well in the community. they have worked the case admirably, and spotted the ionian. i have aided them in all possible ways; but the evidence is not complete. if this steamer proceeds beyond wilmington, captain chantor will be instructed to capture her and send her back to new york."

"then this business will soon be settled," added christy.

"perhaps not; the government official, with authority to act, is in new york. i shall see him at once. i have no doubt the detectives have already reported that the ionian has moved down the river," said captain passford, as the tug came up to a pier, where father and son landed.

they went to an office in battery place, where the captain was informed that a special messenger 32 had been sent to bonnydale to acquaint him with the fact that the ionian had moved down the river. files of documents, containing reports of detectives and other papers, were examined and compared, and then the government official proceeded to finish the filling out of captain chantor's orders. the paper was given to christy, with an order to deliver it to the commander of the chateaugay. the tug had been detained for them, and they hastened on board of her.

they found the suspected steamer at her moorings still; but it was evident that she was preparing to weigh her anchor. the tug continued on her course towards the navy yard, and the chateaugay was discovered in the berth she had occupied for the last two weeks. everything looked lively on board of her, as though she were getting ready to heave up her anchor.

"christy, you will find on board of your steamer a man by the name of gilfleur," said captain passford, as the tug approached the man-of-war.

"that sounds like a french name," interposed christy.

"it is a french name, and the owner of it is a frenchman who has been a detective in paris. he 33 has accomplished more in this matter than all the others put together, and he will go with you, for you will find in the commander's instructions that you have more than one thing to do on your way to the gulf. i gave him a letter to you."

"i shall be glad to see him."

"now, my son, we must part, for i have business on shore, and you may have to sail at any moment," said captain passford, as he took the two hands of his son. "i have no advice to give you except to be prudent, and on this duty to be especially discreet. that's all—good-by."

they parted, after wringing each other's hands, as they had parted several times before. they might never meet again in this world, but both of them subdued their emotion, for they were obeying the high and solemn call of duty; both of them were fighting for the right, and the civilian as well as the naval officer felt that it was his duty to lay down his life for his suffering country. christy mounted the gangway, and was received by captain chantor on the quarter-deck. he had been on board before, and had taken possession of his stateroom.

the passenger took from his pocket the files of 34 papers given him by the official on shore; and then he noticed for the first time an envelope addressed to him. the commander retired to his cabin to read his instructions, and christy went to his stateroom in the ward room to open the envelope directed to him. as soon as he broke the seal he realized that his father had done a great deal of writing, and he had no doubt the paper contained full instructions for him, as well as a history of the difficult case in which he was to take a part. a paper signed by the official informed him that he was expected to occupy a sort of advisory position near the commander of the chateaugay, though of course he was in no manner to control him in regard to the management of the ship.

christy read his father's letter through. the government was exceedingly anxious to obtain accurate information in regard to the state of affairs at nassau, that hot-bed for blockade-runners. the chateaugay was to look out for the ovidio, whose ultimate destination was mobile, where she was to convey the gun-making machinery, and such other merchandise as the traitorous merchant of new york wished to send into the confederacy. the name of this man was given to him, and it was 35 believed that papers signed by him would be found on board of the ionian.

a knock at the door of his room disturbed his examination of the documents, and he found the commander of the steamer there. after looking about the ward room, and into the adjoining staterooms, he came in without ceremony.

"here is my hand, mr. passford," said he, suiting the action to the word. "i find after reading my instructions that i am expected to consult with you, and as i have the very highest respect and regard for you after the brilliant record you have made"—

"don't you believe that i won my promotion to my present rank through the influence of my father?" demanded christy, laughing pleasantly, as he took the offered hand and warmly pressed it.

"if you did, your father did the very best thing in the world for his country, and has given it one of the bravest and best officers in the service," replied captain chantor, still wringing the hand of his passenger. "but i don't believe anything of the kind; and no officer who knows you, even if he is thirsting for promotion, believes it. i have heard a great many of higher rank than 36 either of us speak of you, and if you had been present your ears would have tingled; but i never heard a single officer of any rank suggest that you owed your rapid advancement to anything but your professional skill and your unflinching bravery, as well as to your absolute and hearty devotion to your country. i rank you in date, mr. passford, but i would give a great deal to have your record written against my name."

"your praise is exceedingly profuse, captain chantor, but i must believe you are honest, however unworthy i may be of your unstinted laudation," said christy with his eyes fixed on the floor, and blushing like a school-girl.

"i hope and believe there will be no discount on our fellowship. a man came on board this afternoon, and gives me a letter from the proper authority, referring me to you in regard to his mission."

christy decided to see this person at once.
