Who is Mr. Colman? He is an intelligent, accurate, and cautious witness; a gentleman of high and well-known character, and of unquestionable veracity; as a clergyman, highly respectable; as a man, of fair name and fame.

Why was Mr. Colman with the prisoner? Joseph J. Knapp was his parishioner; he was the head of a family, and had been married by Mr. Colman. The interests of that family were dear to him. He felt for their afflictions, and was anxious to alleviate their sufferings. He went from the purest and best of motives to visit Joseph Knapp. He came to save, not to destroy; to rescue, not to take away life. In this family he thought there might be a chance to save one. It is a misconstruction of Mr. Colman's motives, at once the most strange and the most uncharitable, a perversion of all just views of his conduct and intentions the most unaccountable, to represent him as acting, on this occasion, in hostility to any one, or as desirous of injuring or endangering any one. He has stated his own motives, and his own conduct, in a manner to command universal belief and universal respect. For intelligence, for consistency, for accuracy, for caution, for candor, never did witness acquit himself better, or stand fairer. In all that he did as a man, and all he has said as a witness, he has shown himself worthy of entire regard.

Now, Gentlemen, very important confessions made by the prisoner are sworn to by Mr. Colman. They were made in the prisoner's cell, where Mr. Colman had gone with the prisoner's brother, N. Phippen Knapp. Whatever conversation took place was in the presence of N.P. Knapp. Now, on the part of the prisoner, two things are asserted; first, that such inducements were suggested to the prisoner, in this interview, that no confessions made by him ought to be received; second, that, in point of fact, he made no such confessions as Mr. Colman testifies to, nor, indeed, any confessions at all. These two propositions are attempted to be supported by the testimony of N.P. Knapp. These two witnesses, Mr. Colman and N.P. Knapp, differ entirely. There is no possibility of reconciling them. No charity can cover both. One or the other has sworn falsely. If N.P. Knapp be believed, Mr. Colman's testimony must be wholly disregarded. It is, then, a question of credit, a question of belief between the two witnesses. As you decide between these, so you will decide on all this part of the case.

Mr. Colman has given you a plain narrative, a consistent account, and has uniformly stated the same things. He is not contradicted, except by the testimony of Phippen Knapp. He is influenced, as far as we can see, by no bias, or prejudice, any more than other men, except so far as his character is now at stake. He has feelings on this point, doubtless, and ought to have. If what he has stated be not true, I cannot see any ground for his escape. If he be a true man, he must have heard what he testifies. No treachery of memory brings to memory things that never took place. There is no reconciling his evidence with good intention, if the facts in it are not as he states them. He is on trial as to his veracity.

The relation in which the other witness stands deserves your careful consideration. He is a member of the family. He has the lives of two brothers depending, as he may think, on the effect of his evidence; depending on every word he speaks. I hope he has not another responsibility resting upon him. By the advice of a friend, and that friend Mr. Colman, J. Knapp made a full and free confession, and obtained a promise of pardon. He has since, as you know, probably by the advice of other friends, retracted that confession, and rejected the offered pardon. Events will show who of these friends and advisers advised him best, and befriended him most. In the mean time, if this brother, the witness, be one of these advisers, and advised the retraction, he has, most emphatically, the lives of his brothers resting upon his evidence and upon his conduct. Compare the situation of these two witnesses. Do you not see mighty motive enough on the one side, and want of all motive on the other? I would gladly find an apology for that witness, in his agonized feelings, in his distressed situation; in the agitation of that hour, or of this. I would gladly impute it to error, or to want of recollection, to confusion of mind, or disturbance of feeling. I would gladly impute to any pardonable source that which cannot be reconciled to facts and to truth; but, even in a case calling for so much sympathy, justice must yet prevail, and we must come to the conclusion, however reluctantly, which that demands from us.

It is said, Phippen Knapp was probably correct, because he knew he should probably be called as a witness. Witness to what? When he says there was no confession, what could he expect to bear witness of? But I do not put it on the ground that he did not hear; I am compelled to put it on the other ground, that he did hear, and does not now truly tell what he heard.

If Mr. Colman were out of the case, there are other reasons why the story of Phippen Knapp should not be believed. It has in it inherent improbabilities. It is unnatural, and inconsistent with the accompanying circumstances. He tells you that they went "to the cell of Frank, to see if he had any objection to taking a trial, and suffering his brother to accept the offer of pardon"; in other words, to obtain Frank's consent to Joseph's making a confession; and in case this consent was not obtained, that the pardon would be offered to Frank. Did they bandy about the chance of life, between these two, in this way? Did Mr. Colman, after having given this pledge to Joseph, and after having received a disclosure from Joseph, go to the cell of Frank for such a purpose as this? It is impossible; it cannot be so.

Again, we know that Mr. Colman found the club the next day; that he went directly to the place of deposit, and found it at the first attempt, exactly where he says he had been informed it was. Now Phippen Knapp says, that Frank had stated nothing respecting the club; that it was not mentioned in that conversation. He says, also, that he was present in the cell of Joseph all the time that Mr. Colman was there; that he believes he heard all that was said in Joseph's cell; and that he did not himself know where the club was, and never had known where it was, until he heard it stated in court. Now it is certain that Mr. Colman says he did not learn the particular place of deposit of the club from Joseph; that he only learned from him that it was deposited under the steps of the Howard Street meeting-house, without defining the particular steps. It is certain, also, that he had more knowledge of the position of the club than this; else how could he have placed his hand on it so readily? and where else could he have obtained this knowledge, except from Frank?

Here Mr. Dexter said that Mr. Colman had had other interviews with Joseph, and might have derived the information from him at previous visits. Mr. Webster replied, that Mr. Colman had testified that he learned nothing in relation to the club until this visit. Mr. Dexter denied there being any such testimony. Mr. Colman's evidence was read, from the notes of the judges, and several other persons, and Mr. Webster then proceeded.

My point is to show that Phippen Knapp's story is not true, is not consistent with itself; that, taking it for granted, as he says, that he heard all that was said to Mr. Colman in both cells, by Joseph and by Frank; and that Joseph did not state particularly where the club was deposited; and that he knew as much about the place of deposit of the club as Mr. Colman knew; why, then Mr. Colman must either have been miraculously informed respecting the club, or Phippen Knapp has not told you the whole truth. There is no reconciling this, without supposing that Mr. Colman has misrepresented what took place in Joseph's cell, as well as what took place in Frank's cell.
