The Grand Chief and other officers now took their positions on the platform, and Webster was assigned to a seat where he could observe all that was said or done.

Presently a clock in the room struck twelve. Instantly all the doors opening into the chamber were securely locked, and the secret conclave was in session. The Grand Chief rose and opened the meeting in regular form; and again, after the secretary had read the journal, made an address of some length. At the conclusion of his remarks, some one arose and said:

"Most Worthy Chief, I believe we can now claim Mr. Webster as a member of this body. I understand that he has just returned from an interesting and somewhat dangerous mission, and I now move that he be invited to address this meeting relative to his experiences during the journey he has just completed."

Webster, taken by surprise, undertook to combat the proposition, but the motion was unanimously concurred in, and no excuses were accepted. He therefore yielded good-naturedly, and mounting the platform, he proceeded to relate some of the particulars of his trip to the Potomac. He made the recital as entertaining and agreeable as possible, and although his statements did not always possess the merit of being strictly true, they were such as could not fail to meet the approval of his hearers, and were therefore received with great favor. Concluding with a well-timed panegyric on the "faithful" of Baltimore, he resumed his seat amid the congratulations of his many admiring friends.

After this, the regular business of the meeting was taken up, in which Webster took no other part than that of a close listener and observer. Motions were made, resolutions were adopted, and various duties assigned to volunteer committees. The proceedings grew more and more interesting to the detective as they progressed, and it was not long before he began to feel considerable surprise, if not alarm, at the unexpected revelations which were made. It became evident to him that these conspirators had by some means succeeded in placing themselves in direct communication with the Confederate leaders, and that a gigantic plot was now in preparation to make a united and irresistible movement against Washington. Nearly ten thousand Baltimoreans, it was alleged, were prepared to rise in arms at a moment's notice, and join the rebel army, whenever such a movement might seem feasible. It appeared, also, that the Baltimoreans were not alone in this plot against the government, but that branches of their organization existed in a number of the outlying towns, and that the secessionists of the entire State were working harmoniously together for the accomplishment of one great purpose. There was no lack of arms, for these had already been secured, but their place of concealment was known only to a few and they were not to be brought to light until they should be needed.

The main portion of the plot seemed to be well matured, and was most perfect in its details. The arrival of the rebel army in Maryland was expected in a very short time, as they had the promises of the Southern commanders themselves that they would soon cross the Potomac. Their coming was to be the signal for a simultaneous uprising of all the secessionists in the Western and Southern portions of the State, who were to unite in a movement that could scarcely fail to carry everything before it. There were also deep-laid schemes by which the Federals were to be kept in ignorance of the real designs of the Confederates, until too late to avert the blow.

The extent of the conspiracy rather startled Webster, although some of the projects sounded rather visionary, and he made up his mind to consult with me at once. Accordingly, the very next day, he proceeded to Washington, and was closeted with me for several hours. As soon as he had explained the situation, I devised a plan of procedure, and gave him full instructions as to the manner in which he should proceed. The great object, of course, was to break up the organization, and defeat the conspiracy in a manner that would not compromise Webster; but it was not deemed prudent to go about this with any inordinate haste.

I advised Webster to continue attending the meetings, in the character of an active conspirator; to learn all he could, and report to me as often as possible. In the meantime, I would send him two other operatives, and he was to secure their admission into the secret society, as members thereof. In a week or two the final act in the little drama would be introduced by first making a confidant of Mr. McPhail, the deputy Provost-Marshal of Baltimore, and then confronting the conspirators with a company of armed soldiers.

Webster returned to Baltimore with a clear understanding of the course he was to pursue, and he followed that course with the untiring zeal with which he performed every duty assigned to him. He attended the midnight meetings regularly, and gained much information concerning the plans and movements of the Southern commanders, which proved of incalculable value to the government. The two operatives soon contrived to join the society, not through Webster's recommendation, as that was to be avoided, if possible, but by making the acquaintances of men whom he pointed out to them, and representing themselves as secessionists who were capable of keeping their own counsel.

This done, the rest was comparatively easy. By the rules of the society, no one could enter the secret chamber of the conspirators without passing two guards, and giving sundry pass-words. These guards were appointed by the Chief from those who volunteered for the positions. At stated periods, new pass-words were arranged, by which every man was required to answer the questions of the guards, and any one who failed to commit these to memory sufficiently to satisfy these sentinels that he was a member of the society, found himself barred out of the meeting.
