“I requested Jackson to make me a detailed report from the day he left my house up to the date of his return, which he did. I retained a copy of his report, and still have it. We did not call on Henry for his report that day, but on the next told Henry that if he could leave Seraine long enough (you know how young people are), we would like him to tell us what he learned in Canada. I really did not suppose that he could tell us a very great deal of interest, as I presumed he had spent much of his time in Detroit, as there was an attraction for him in that place which would naturally draw him thither. He said, however, that he was ready to tell us all that he had discovered in reference to the conspiracy; that when he went to Canada he formed the acquaintance of a Mr. Samuel Wintergreen, and soon they became great friends, as he satisfied Winter-green that he was ready to carry out any plan to aid the Confederacy. The passwords, signs and grips of the Golden Circle seemed to be all that any one needed in order to be at once recognized as a friend to those people. In Canada the people, almost without exception, were in sympathy with the rebellion. After traveling for quite a while he came back to Windsor, and there again met his friend Wintergreen. Remaining there for some time and talking with many persons without any material results, Wintergreen invited Henry to accompany him to Toronto, and finding nothing of importance there, they left for Montreal On arriving at Montreal they found Jacob Thomlinson, C. C. Carey, and many other distinguished men. Wintergreen met Jacob Thomlinson, and reported to him that his friend of whom he had written was with him. Thomlinson asked him to come to his rooms, and to bring his friend Davis. That evening they visited Mr. Thomlinson, and found Mr. Carey and two other gentlemen--a Mr. Landers and Ben Wudd. Henry was presented as Henry Davis, one of the agents under Mr. Wintergreen who was to assist (as it was then understood) in carrying out such plans as might be agreed upon in the interest of the rebel or Confederate Government. “They remained together till a late hour discussing various points. One of the topics was the great loss the Confederacy had sustained in the burning of the Will-o'-the-Wisp, in the material, and by the death of Prof. McCul-lough and Dr. Mears, as they alone held the secret of manufacturing the wonderful explosive. Thomlinson and Carey insisted that there should be no let-up, and that they must now resort to other means, in which the other gentlemen agreed. It was thought best to try releasing prisoners and arming them and such others as would join them, and make portions of the North a desolate waste, as they said was now being done in the South by the Union army. Thomlinson said in reference to releasing prisoners that he intended in a very short time to make preparations in Illinois for an attack on Camp Douglas, near Chicago.
