Having now, sir, endeavored to show the futility of the testimony adduced to support this charge, it might be sufficient here to rest our defence of the honorable member accused. But, sir, though more may be unnecessary, I rejoice that more is in our power; that we have been enabled not only to destroy the force of the proof offered to criminate him, but to exhibit the most complete and direct evidence of his innocence. I am sensible, sir, that I have trespassed greatly upon the indulgence of this honorable Senate. I shall not, therefore, take that view of this part of the case which its importance deserves; but will only beg leave to suggest a few considerations which appear to my mind unanswerable, which will render all doubt upon this subject (if indeed a doubt yet remains) utterly impossible.

In the first place, to what but his innocence can it be attributed that such numbers of the conspirators knew nothing of his association with them? We have produced the depositions of several who appear to admit that they had been induced to participate in this enterprise, and they declare their ignorance and disbelief that Mr. Smith was in any way concerned in it. Nay, sir, let us look at the declarations of their chief, Colonel Burr himself. He has various communications with persons whom he was desirous to bring over to his views, many of which are detailed to us in the report of the evidence at Richmond. In these he makes the most flattering representations of his prospects, endeavors to show the adequacy of his means, the number and consequence of his adherents. Among these he never mentions Mr. Smith, though there was no man, in the whole Western country, the importance of whose co-operation would have been more obvious. Here is one striking instance of this, which I beg leave to mention. Lieutenant Jackson deposes that when Colonel Burr gave him the draught on Mr. Smith, he directed him to call on General Tupper, to whom he referred him for information relative to the objects of the enterprise. Now, sir, if Colonel Burr had known Mr. Smith as one of his associates, why should he have been silent on this occasion; why should he not have allowed Mr. Jackson to get his information from Mr. Smith, when he presented his draught, without proceeding to General Tupper?

All the other conspirators seem equally ignorant of Mr. Smith’s participation. When Bollman and Swartwout communicated with General Wilkinson, in the most unreserved manner, they seem to know nothing of it; they give him no intimation that the army contractor, the very man who was supplying his troops with provisions, had any connexion with their schemes.

Let us even descend to Glover and McFarland; that these men were engaged in this expedition, after the proofs we have produced, cannot be questioned. And what are they able to say to criminate Mr. Smith?

If they were all living in the same place, associates in the same conspiracy, is it possible they would not have had frequent interviews? Would they not have had it in their power to produce some act, or at least some avowal to others, by which his guilt could be proved, beyond the possibility of denial? Yet we hear Mr. McFarland frequently acknowledging and twice even swearing that he knew nothing of Mr. Smith’s connexion with it; and all that their malignant efforts have enabled them to collect, is one solitary conversation depending wholly upon the unsupported assertion of Elias Glover.

Thus, sir, it appears that if Mr. Smith was a party in this conspiracy, the persons from whom he most studiously concealed it were those who were associated in the same project. Neither are they more fortunate who were particularly engaged in watching the progress of this enterprise and ascertaining who were its partisans. General Gano states that he used various means to determine whether the reports relative to Mr. Smith were well founded, and he satisfied himself of his innocence. He also directed Major Riddle to assist this inquiry; that officer reported to him that he had frequent conversations with Mr. Smith, and had endeavored to ascertain whether he knew anything of Burr’s plans, and was convinced that he did not. Even Colonel Taylor, with whom these suspicions were strengthened by the conversation relative to a disunion, which he thought he had heard from Mr. Smith, was yet so far from discovering any thing to confirm them in his inquiries, that he calls on Mr. Smith to aid him in procuring information, and frequently declares (as General Carberry’s deposition informs us) that he did not believe Mr. Smith was an accomplice.

In the next place, sir, how can Mr. Smith’s guilt be in any manner reconciled with his conduct in opposing the progress of the expedition. Major Martin, Dr. Stall, General Gano, Mr. Totten, and numerous other witnesses, prove that it was principally owing to Mr. Smith’s exertions that any effectual support was rendered to the measures of Government. When the President’s proclamation was received at Cincinnati, it seems there was no means of arming the militia. The orders to the keepers of the arsenal, to deliver out the public arms, had been neglected, and he persisted in refusing to deliver them without. At this juncture Mr. Smith, with that earnestness and decision which so strongly mark his character, crosses the river at midnight, offers his bond to Major Martin, in the penalty of $10,000, to indemnify him; procures the arms, and delivers them to the officers; prepares barracks and supplies for the militia; furnishes one of his own boats, and in short makes every arrangement to obstruct the passage of the expected armament.

It may perhaps, sir, be here objected, that these circumstances rather prove that Mr. Smith then abandoned the enterprise than that he never participated in it. That the vigilant measures taken by Government alarmed him, and that therefore, hopeless of its success, he sought by a zealous opposition to escape detection. However plausible this may seem, the least reflection will show how unreasonable is this suspicion.

How does it appear that the situation of the conspirators was at this time more unpromising than at any former period? They had thus far proceeded without meeting any obstacles; their plans were arranged and ripe for execution; they were hourly expected to embark. And what was there so alarming in the measures taken to oppose them as to strike a panic into Mr. Smith and subvert his resolutions? The militia were called out it is true, but they were without arms. Their officers inform us that they could not even station a guard upon the river. I should rather suppose that this circumstance would have been considered as more auspicious than any thing he could have expected. Nor does it appear that this effect was produced in the minds of any of the party. For even at a subsequent period, and after the militia, by Mr. Smith’s exertions, had procured arms, we find Captain Nicholls at Cincinnati still adhering to their views and far from despairing. Nay, even Elias Glover, (whose courage appears from Dr. Lanier’s deposition to be about equal to his veracity,) and who doubtless was as ready as any one to renounce his associates when he saw them sinking, is seen at the same period persisting in his adherence to them. He tells Captain Nicholls to hasten his departure lest the guard should stop his boats, declares that he will shortly follow, and informs him that he had sent off an express to the party at the island. There is one other circumstance that totally overthrows this suspicion. If Mr. Smith had thus not only deserted but opposed his associates, would it not have excited their resentment? And would they not have revenged themselves for his treachery by disclosing his participation, and showing that he was equally guilty with themselves?

It cannot be necessary to contrast this conduct with that which we might expect to find in Mr. Smith, if, most unfortunately for his country and for himself, he had really been concerned in this enterprise. It is well known that the circumstance which first excited the suspicion of Government were the unusual preparations made by Colonel Burr and his party on the Western waters. From these suspicions they would have been perfectly secure by obtaining the co-operation of Mr. Smith. His contracts for the supply of the army, and his engagements to prepare boats for the navy, would have enabled him to collect any quantity of provisions and materials, and place them in suitable situations without exciting the least attention: and whenever they were ready to act, he might in a moment have stopped the supplies of your armies, and suddenly directed all his resources to aid in the most effectual and fatal manner the objects of the combination.
