"I am a native of London, Eng., but have lived south nine or ten years. During the past year I have resided in Toronto, Can. About the middle of December, 1863, I made the acquaintance of Dr. Blackburn. I was introduced to him by the Rev. Stewart Robinson at the Queen's Hotel in Toronto. I knew him by sight previously, but before that had no conversation with him. I knew that he was a Confederate and was working for the rebellion. Dr. Blackburn was then about to take south some men who had escaped from the federal service, and I asked to go with him. He asked me if I wanted to go south and serve the Confederacy. I said I did. He then told me to come upstairs to a private room, as he wanted to speak to me. He took me upstairs, and after we had entered his room he pledged his word as a freemason, and offered his hand in friendship, that he would never deceive me. He said he wanted to confide to me an expedition. I told him I would not care if I did. He said I would make an independent fortune by it, at least one hundred thousand dollars, and get more honor and glory to my name than General Lee, and be of more assistance to the Confederate government than if I was to take one hundred thousand soldiers to reinforce General Lee. I pledged my word that I would go if I could do any good. He then told me he wanted me to take a certain quantity of clothing, consisting of shirts, coats, and underclothing, into the States, and dispose of them by auction. I was to take them to Washington City, to Norfolk, and as far south as I could possibly go, where the federal government held possession and had the most troops, and to sell them on a hot day or of a night; that it did not matter what money I got for the clothing, I had just to dispose of them in the best market where there were the most troops, and where they would be most effective, and then come away. He told me I should have one hundred thousand dollars for my services, sixty thousand dollars of it directly after I returned to Toronto; but he said that would not be a circumstance to what I should get. He said I might make ten times one hundred thousand dollars. I was to stay in Toronto, and go on with my legitimate business until I heard from him. He told me to keep quiet, and if I moved anywhere I was to inform Dr. Stewart Robinson where I went to, and he would telegraph for me, or write to me through him. Sometime in the month of May, 1864, I went to my work and worked on until the 8th day of June, '64; it was on a Saturday night; I had been out to take a pair of boots home to a customer of mine; when I returned home my wife had a letter for me from Dr. Blackburn, which Dr. Stewart Robinson had left in passing there. I read the letter, and went out to see Dr. Robinson. I asked him what I was to do about it. He said he did not know anything about it; that he did not want to furnish any means to commit an overt act against the United States government. He advised me to borrow from Mr. Preston, who keeps a tobacco manufactory in Toronto, enough money to take me to Montreal, and there get money from Mr. Slaughter, according to the directions contained in Dr. Blackburn's letter. This letter instructed me to proceed from Montreal to Halifax to meet Dr. Blackburn; it was dated Havana, May 10th, 1864. I went to Halifax to a gentleman by the name of Alexander H. Keith, Jr., and remained under his care until Dr. Blackburn arrived in the steamer 'Alpha,' on the 12th of July, 1864. When Dr. Blackburn arrived he sent to the Farmer's Hotel, where I was staying, for me. I went to see him, and he told me that the goods were on board the steamer 'Alpha,' and that the second officer on the steamer would go with me and get the goods off, as they had been smuggled in from Bermuda. Mr. Hill, the second officer, told me to get an express wagon and take it down to Cunard's steamboat wharf. I did so, and there got eight trunks and a valise. I was directed to take them to my hotel, and put them in a private room. I put them in Mr. Doran's private sitting-room. I then went around to Dr. Blackburn, and told him I had got the goods off the steamer. He told me that the five trunks tied up with ropes were the ones for me to take, and asked me if I would take the valise into the States and send it by express, with an accompanying letter, as a donation to President Lincoln. I objected to taking it, and refused to do so. I then took three of the trunks and the valise around to the hotel. He was then staying at the Halifax Hotel. The trunks had Spanish marks upon them, and he told me to scrape them off, and that Mr. Hill would go with me the next morning and make arrangements with some captain of a vessel to take them. There were two vessels there running to Boston, and I was to make an arrangement with either of them to smuggle the trunks through to Boston. The next morning I went down with Mr. Hill to the vessels. Mr. Hill had a private conversation with Captain McGregor, the captain of the first vessel, to whom we applied to take the goods, and he refused.

"We then went to see Captain O'Brien of the bark 'Halifax.' Hill told him that I had some presents in my trunks, consisting of silks, satin dresses, etc., that I wanted to take to my friends. The Captain and Mr. Hill had a private conversation, and when the Captain came out he consented to take them. I was to give him a twenty-dollar gold piece for smuggling them in. I put them on board the vessel that day and he stowed them away. The vessel lay five days at Boston before he could get a chance to get them off, but finally he succeeded in getting them off, and expressed them to Philadelphia, where I received them and brought them to Baltimore. I then took out the goods, which were very much rumpled, and smoothed them out and arranged them, bought some new trunks, and repacked them and brought them to this city. Dr. Blackburn, by way of caution, asked me before leaving if I had had the yellow fever, and on my saying 'no,' he said, 'You must have a preventive against taking it. You must get some camphor and chew it, and get some strong cigars, the strongest you can get; and be sure to keep gloves on your hands when handling the things.' He gave me some cigars that he said he had brought from Havana, which he said were strong enough for anything. When I arrived in this city, I turned over five of the trunks to Messrs. W. L. Wall & Company, commission merchants in this city, and four to a man by the name of Myers, from Boston, a sutler for Siegel's or Weitzel's division. He said he had some goods which he was going to take to New Berne, N.C., and I told him that I had a lot of goods that I wanted to sell, and, to make the best market I could for them, I would turn them over to him on commission. I also told him I would shortly have more, and mentioned that I had disposed of some to Wall & Company, of this city. Dr. Blackburn told me, when I was making arrangements, that I should let the parties to whom I disposed of my goods know that I would have a big lot to sell, as it was in contemplation to get together about a million dollars' worth of goods and dispose of them in that way. Dr. Blackburn stated that his object in having these goods disposed of in different cities was to destroy the armies, or anybody that they came in contact with. All these goods, he told me, had been carefully infected in Bermuda with yellow fever, small-pox, and other contagious diseases.

"The goods in the valise, which were intended for President Lincoln, I understood him to say had been infected with yellow fever and small-pox. This valise I declined taking charge of and turned it over to him at Halifax Hotel, and I afterwards heard that it had been sent to the President. On the five trunks that I turned over to Wall & Company I got an advance of one hundred dollars. Among these five trunks there was one that was always spoken of by Blackburn to me as 'Big No. 2,' which he said I must be sure to have sold in Washington. On disposing of the trunks I immediately left Washington, and went straight through until I got to Hamilton, Canada. In the waiting-room there I met Mr. Holcomb and Clement C. Clay. They both rose, shook hands with me, and congratulated me upon my safe return, and upon my making a fortune. They told me I should be a gentleman for the future, instead of a working man and a mechanic. They seemed perfectly to understand the business in which I had been engaged.

"Mr. Holcomb told me that Dr. Blackburn was at the Donegan Hotel, in Montreal, and that I had better telegraph to him stating that I had returned. As Dr. Blackburn had requested me to telegraph to him as soon as I got into Canada, I did so, and the next night, between eleven and twelve o'clock, Dr. Blackburn came up and knocked at the door of my house. I was in bed at the time. I looked out of the window, and saw Dr. Blackburn there. Said he, 'Come down, Hyams, and open the door; you are like all damned rascals who have been doing something wrong—you're afraid that the devil is after you.' He was in company with Bennett H. Young. I came down and let him in. He asked me how I had disposed of the goods and I told him. 'Well,' said he 'that is all right as long as "Big No. 2" went into Washington; it will kill them at sixty yards distance.' I then told the doctor that everything had gone wrong at my home in my absence; that I needed some funds; that my family needed money. He said he would go to Colonel Jacob Thompson and make arrangements for me to draw upon him for any amount of money that I required. He then said that the British authorities had solicited his services in attending the yellow fever that was then raging in Bermuda; that he was going on there; and that as soon as he came back he would see me. I went up to Jacob Thompson the next morning, and told him what Dr. Blackburn had said. He said 'Yes'; Dr. Blackburn had been there and had made arrangements for me to draw one hundred dollars whenever it was shown that I had made disposition of the goods according to his directions. I told him I needed money; that I had been so long away from home that everything I had was gone, and I wanted money to pay my rent, etc. He said, 'I will give you fifty dollars now, but it is against Dr. Blackburn's request; when you show me that you have sold the goods, I will give you the balance.' He asked me to give him a receipt, which I did: 'Received of Jacob Thompson the sum of fifty dollars on account of Dr. Blackburn.' That was about the 11th or 12th of August last. The next day I wrote to Messrs. Wall & Company, of Washington, desiring them to send me an account of the sales, and the balance due me. When I received their answer, I took it to Colonel Thompson. He then said he was perfectly satisfied I had done my part, and gave me a check for fifty dollars on the Ontario Bank. I gave him a receipt: 'Received of Jacob Thompson one hundred dollars in full on account of Dr. Luke P. Blackburn.' I told Thompson of the large sum which Dr. Blackburn had promised me for my services and that he and Mr. Holcomb had both told me that the Confederate government had appropriated two million dollars for the purpose of carrying it out; but he would not pay me any more. When Dr. Blackburn returned from Bermuda, I wrote to him at Montreal, and told him I wanted some money, and that he ought to send me some; but he made no reply to my letter. I was then sent down to Montreal with a commission for Bennett H. Young, to be used in his defense in the St. Albans raid case. I there met Dr. Blackburn. He said I had written some hard letters to him, abusing him, and that he had no money to give me. He then got into his carriage at the door and rode off to some races, I think, and never gave me any more satisfaction. As I wanted money before leaving for the States, I went to the Clifton House, Niagara. Dr. Blackburn told me he had no money with him then, but that he would go to Mr. Holcomb and get some, as he had Confederate funds with him. Blackburn said that when I returned he would get the money for the expedition from either Holcomb or Thompson, it did not matter which. From this, and from Holcomb and Clay both shaking hands with me and congratulating me at Hamilton upon my safe return, I thought, of course, they knew all about it. I do not know that Dr. Stewart Robinson knew of the business in which I was engaged, but he took good care of me while I was at Toronto, in the fall, and until Dr. Blackburn wrote for me in the spring; and when he gave me Dr. Blackburn's letter, he told me to borrow the money from Mr. Preston to take me to Montreal, as he said he did not want to commit an overt act against the Government of the United States himself. Mr. Preston lent me ten dollars to go to Montreal. On arriving at that place, according to the directions of Dr. Blackburn's letter, I went to Mr. Slaughter to get the means to take me to Halifax. Mr. Slaughter was short of funds, and had only twenty dollars that he could give me. He said that I had better go to Mr. Holcomb, who was staying at the Donegan Hotel, and he would give me the balance. I went to the Hotel and sent up my name, and he sent for me to come up. I told him I wanted some money to take me to Halifax; he asked me how much I wanted; I told him as much as would make up forty dollars; he said 'You had better take fifty dollars,' but as I did not want that much I only took enough to make forty dollars. When I came to Washington to dispose of my goods, which was on the 5th of August, 1864, I put up at the National Hotel, registered my name as J. W. Harris, under which name I did business with Wall & Company."

Here we have a straightforward, circumstantial account of the efforts made and the means used to spread pestilence and death amongst citizens and soldiers alike, in the capital of the nation, and in other cities and camps, a special consignment, supposed to contain the contagion of yellow fever and small-pox, being sent as "a donation to President Lincoln." This was for the purpose of taking his life, and at the risk of the lives of his household. Blackburn, Clay, Thompson, and Holcomb were the originators of the plan, and as guilty as the infamous scoundrel, Hyams, who, to gratify his desire for revenge on them for their perfidy in putting him off with a mere pittance of the promised reward for his services in the matter, comes before the Commission and reveals the whole history of their infamy. No one who reads his story will doubt that he was a conscienceless scoundrel, who, for the hope of obtaining a large sum of money, according to their promise, was willing to make himself an instrument in the wholesale and indiscriminate destruction of human life. But monster as he was, he was not more a monster than was each one of his employers. He was evidently a man well qualified for the task in which he was employed; in the first place destitute of conscience, and then a man of a good degree of intelligence, shrewdness, and knowledge of affairs. Granting that he was selected by Dr. Robinson, and recommended by him to Dr. Blackburn, he could not have made a better selection had he had full knowledge of the work cut out for him to do. And when we consider Blackburn's perfidy in his dealings with him, pledging his faith as a freemason and giving him his hand in friendship, assuring him that he would never deceive him; then building him up in the idea that he would receive one hundred thousand dollars, and perhaps ten times that amount as his reward; and then, after he had performed a service that put his own life in jeopardy, to put him off with a mere pittance of the amount promised, we cannot wonder that a man constituted as Hyams was should divulge the terrible secret in revenge for the shabby treatment he had received at their hands.

See how Clay and Holcomb meet him on his return! They understand all about the character of his mission, congratulate him on his safe return, and on the fact that from thenceforth he was not to be known as a laboring man and a mechanic, but as a gentleman.

No wonder that he, when for the pitiful sum of one hundred dollars he had signed for Thompson a receipt in full on account of Dr. Blackburn, vowed to have revenge. How true it is that there must be honor even amongst the worst of villains, in order that they may hang together. They broke faith with Hyams, and Hyams revealed circumstantially, and fully, their great crime against humanity. We have now seen these men planning to poison the water supply of New York City to the extent of fatality to its whole population, men, women, and children,—helpless age, and more helpless infancy doomed to death by the scope of their plan; and now, we have found them engaged in an effort to spread pestilence with the same purpose of the indiscriminate destruction of human life. What worse can they do? Can we after this be surprised at anything they may undertake? It will not avail to say that a man who could be hired to do such a thing as this is unworthy of credence, even under oath, and so that his testimony is not to be received. Hyams' story bears on its face the marks of a truthful narrative of the facts, just as they occurred, and it does not follow that because a man is a confessed scoundrel he is incapable of telling the truth. No adequate motive for falsehood in this case can be assigned. Had his employers kept faith with him, he would no doubt have kept their terrible secret, and it would have been buried with him. That they did not, only becomes a reason for his disclosure of the facts, not for his fabrication of falsehoods. But then his statement as to how he disposed of the goods in Washington City is fully confirmed by the testimony of Wall & Company, who produced an account of the transaction agreeing exactly, in date and amount, with that given by Hyams, and also in regard to his alias of J. W. Harris. It was also corroborated by the National Hotel register of that date.

Conover testified to this as one of the schemes planned by Thompson and his gang, and Hyams gives a full account of the manner of its execution. For some reason the infection was a failure in Washington City; but not so with the goods sent by Myers, the sutler, to New Berne, N.C. It will be recollected that an epidemic of yellow fever broke out there in the latter part of the summer of 1864, that swept away large numbers of people, both citizens and soldiers. No doubt this epidemic was due to the infection carried in the clothing that Myers received from Hyams, to be sold on commission; and that in the great day of final account these men will find themselves arraigned as the murderers of all those who fell as the victims of their hellish plot, before a tribunal that is infinitely perfect in its knowledge and just in its decisions.

Plot to Burn New York City and its Attempted Execution.

The plot to burn the city of New York was attempted to be carried out on the 25th of November, 1864. I will give the history of this attempt as narrated in his confession, by Robert C. Kennedy, one of the gang of incendiaries sent there for that purpose, who was arrested, tried, found guilty, condemned, and hanged for his crime. Before his execution he made a full confession as follows:—
