By these secret organizations, the enemies of the government, wherever they might be, possessed the means of a secret recognition amongst their members. And under whatever circumstances they might be placed, the obligations of their oath afforded them confidence and security. They constituted a brotherhood, and by their secret grips, signs, passwords, etc., they had a guarantee of unity of sentiment and of purpose, and of faithfulness to each other and to the obligations of their oath. These organizations were regarded as allies by the rebel government, and were counted on as a valuable factor to secure the success of its arms. This element in the North kept itself in constant communication with the rebel government and the rebel armies, and thus, in a large degree, filled the place of spies in giving information. To furnish facilities for communication with its friends in the North, as also for various other purposes in aid of the rebel cause, the Confederate Government sent a number of its ablest civilians to Canada, at an early period of the war, as its secret agents, who established their headquarters at Montreal. This cabal consisted of the following persons: Jacob Thompson, who had been Secretary of the Interior under Buchanan's administration; Clement C. Clay, who had been a United States Senator from Alabama; Beverly Tucker, who had been a Circuit Judge in Virginia; George N. Sanders, William C. Cleary, Prof. Holcomb, George Harper, and others. Of these, Thompson, Tucker, and Clay seem to have held semi-official positions, and we will designate them as Davis's Canada Cabinet. The others named, as also others unnamed above, appear to have acted as aids, in a subordinate capacity, in the execution of their plots. They all claimed to be acting as agents of the Rebel Government upon their oaths on the trial for the extradition of the St. Alban's raiders.
