tor was about to do? Would he have tried to shield him? Would he have furnished his cloak for protection? Would he have pointed out a safe way of retreat? As you would answer these questions, so you should answer the general question, whether he was there consenting to the murder, or whether he was there as a spectator only.

One word more on this presence, called constructive presence. What aid is to be rendered? Where is the line to be drawn, between acting, and omitting to act? Suppose he had been in the house, suppose he had followed the perpetrator to the chamber, what could he have done? This was to be a murder by stealth; it was to be a secret assassination. It was not their purpose to have an open combat; they were to approach their victim unawares, and silently give the fatal blow. But if he had been in the chamber, no one can doubt that he would have been an abettor; because of his presence, and ability to render services, if needed. What service could he have rendered, if there? Could he have helped him to fly? Could he have aided the silence of his movements? facilitated his retreat, on the first alarm? a case where there was more of safety in going alone than with another; where company would only embarrass. Richard Crowninshield would prefer to go alone. He knew his errand too well. His nerves needed no collateral support. He was not the man to take with him a trembling companion. He would prefer to have his aid at a distance. He would not wish to be encumbered by his presence. He would prefer to have him out of the house. He would prefer that he should be in Brown Street. But whether in the chamber, in the house, in the garden, or in the street, whatsoever is aiding in actual presence is aiding

Could he have Surely, this was

in constructive presence; anything that is aid in one case is aid in the other.

If, then, the aid be anywhere, so as to embolden the perpetrator, to afford him hope or confidence in his enterprise, it is the same as though the person stood at his elbow with his sword drawn. His being there ready to act, with the power to act, is what makes him an abettor.

Here Mr. Webster referred to the cases of Kelly, of Hyde, and others, cited by counsel for the defendant, and showed that they did not militate with the doctrine for which he contended. The difference is, in those cases there was open violence; this was a case of secret assassination. The aid must meet the occasion. Here no acting was necessary, but watching, concealment of escape, management.

What are the facts in relation to this presence? Frank Knapp is proved to have been a conspirator, proved to have known that the deed was now to be done. Is it not probable that he was in Brown Street to concur in the murder? There were four conspirators. It was natural that some one of them should go with the perpetrator. Richard Crowninshield was to be the perpetrator; he was to give the blow. There is no evidence of any casting of the parts for the others. The defendant would probably be the man to take the second part. He was fond of exploits, he was accustomed to the use of sword-canes and dirks. If any aid was required, he was the man to give it. At least, there is no evidence to the contrary of this.

Aid could not have been received from Joseph Knapp, or from George Crowninshield. Joseph Knapp was at Wenham, and took good care to prove that he was there. George Crowninshield has proved satisfactorily where he was; that he was in other company, such as it was, until eleven

o'clock. This narrows the inquiry. This demands of the prisoner to show, if he was not in this place, where he was. It calls on him loudly to show this, and to show it truly. If he could show it, he would do it. If he does not tell, and that truly, it is against him. The defence of an alibi is a double-edged sword. He knew that he was in a situation where he might be called upon to account for himself. If he had had no particular appointment or business to attend to, he would have taken care to be able so to account. He would have been out of town, or in some good company. Has he accounted for himself on that night to your satisfaction?

The prisoner has attempted to prove an alibi in two ways. In the first place, by four young men with whom he says he was in company, on the evening of the murder, from seven o'clock till near ten o'clock. This depends upon the certainty of the night. In the second place, by his family, from ten o'clock afterward. This depends upon the certainty of the time of the night. have no connection with each other. the other false, or they may both be true, or both be false. I shall examine this testimony with some attention, because, on a former trial, it made more impression on the minds of the court than on my own mind. I think, when carefully sifted and compared, it will be found to have in it more of plausibility than reality.

These two classes of proof
One may be true, and

Mr. Page testifies, that on the evening of the 6th of April he was in company with Burchmore, Balch, and Forrester, and that he met the defendant about seven o'clock, near the Salem Hotel; that he afterward met him at Remond's, about nine o'clock, and that he was in company with him a considerable part of the evening. This young gentleman is a

member of college, and says that he came to town the Saturday evening previous; that he is now able to say that it was the night of the murder when he walked with Frank Knapp, from the recollection of the fact, that he called himself to an account, on the morning after the murder, as it is natural for men to do when an extraordinary occurrence happens. Gentlemen, this kind of evidence is not satisfactory; general impressions as to time are not to be relied on. If I were called on to state the particular day on which any witness testified in this cause, I could not do it. Every man will notice the same thing in his own mind. There is no one of these young men that could give an account of himself for any other day in the month of April. They are made to remember the fact, and then they think they remember the time. The witness has no means of knowing it was Tuesday rather than any other time. He did not know it at first; he could not know it afterward. He says he called himself to an account. This has no more to do with the murder than with the man in the moon. Such testimony

is not worthy to be relied on in any forty-shilling cause. What occasion had he to call himself to an account?

Did

he suppose that he should be suspected? Had he any intimation of this conspiracy?

Suppose, gentlemen, you were either of you asked where you were, or what you were doing, on the fifteenth day of June; you could not answer this question without calling to mind some events to make it certain. Just as well may you remember on what you dined each day of the year past. Time is identical. Its subdivisions are all alike. No man knows one day from another, or one hour from another, but by some fact connected with it. Days and hours are not visible to the senses, nor to be apprehended and distinguished

by the understanding. The flow of time is known only by something which marks it; and he who speaks of the date of occurrences with nothing to guide his recollection speaks at random, and is not to be relied on. This young gentleman remembers the facts and occurrences; he knows nothing why they should not have happened on the evening of the 6th; but he knows no more. All the rest is evidently conjecture or impression.

Mr. White informs you, that he told him he could not tell what night it was. The first thoughts are all that are valuable in such case. They miss the mark by taking second aim.

Mr. Balch believes, but is not sure, that he was with Frank Knapp on the evening of the murder. He has given different accounts of the time. He has no means of making it certain. All he knows is, that it was some evening before Fast day. But whether Monday, Tuesday, or Saturday, he cannot tell.

Mr. Burchmore says, to the best of his belief, it was the evening of the murder. Afterward he attempts to speak positively, from recollecting that he mentioned the circumstance to William Peirce, as he went to the Mineral Spring on Fast day. Last Monday morning he told Colonel Putnam he could not fix the time. This witness stands in a much worse plight than either of the others. It is difficult to reconcile all he has said with any belief in the accuracy of his recollections.

Mr. Forrester does not speak with any certainty as to the night; and it is very certain that he told Mr. Loring and others that he did not know what night it was.

Now, what does the testimony of these four young men amount to? The only circumstance by which they approxi
