[Nov. 27.] On Tuesday commences the trial of William Wemms, James Hartegan, William M‘Cauley, Hugh White, Matthew Killroy, William Warren, John Carrol, and Hugh Montgomery, soldiers in the 29th regiment, for the murder of Crispus Attucks, Samuel Gray, Samuel Maverick, James Caldwell, and Patrick Carr, the last of whom did not die till ten days after he was wounded. The soldiers have the same counsel that was engaged for their captain. The trial is continued from day to day, Sunday excepted, till Wednesday, December the fifth. Attempts were made to prejudice the people against the prisoners, one especially in a certain weekly paper the day before the trial began. The publication included an insult on the supreme court, and expressed the greatest malignity of heart.—To counteract the baneful effects of all such proceedings, Mr. Quincy, in his address to the justices and jury, observes—“We must steel ourselves against passions, which contaminate the fountain of justice. Let it be borne deep upon our minds, that the prisoners are to be condemned by the evidence _here in court_ produced against them, and by nothing else. Matters heard or seen abroad, are to have no weight; in general they undermine the pillars of justice and truth. As though a series of _ex parte_ evidence was not enough, all the colours of the canvas have been touched in order to freshen the wounds, and by a transport of imagination we are made present at the scene of action. The prints exhibited in our houses have added wings to fancy, and in the fervor of our zeal, reason is in hazard of being lost. The pomp of funeral, the horrors of death, have been so delineated, as to give a spring to our ideas, and inspire a glow incompatible with sound, deliberate judgment. In this situation, every passion has alternately been predominant. They have each in turn subsided in degree, and they have sometimes given place to despondence, grief, and sorrow. How careful should we be, that we do not mistake the impressions of gloom and melancholy, for the dictates of reason and truth! How careful, lest borne away by a torrent of passion, we make shipwreck of conscience! “Many things yet exist sufficient to keep alive the glow of indignation. I have aimed at securing you against the catching flame. I have endeavored to discharge my duty in this respect. What success will follow those endeavors, depends on you, gentlemen. If being told of your danger will not produce caution, nothing will. If you are determined in opinion, it is in vain to say more; but if you are zealous enquirers after the truth; if you are willing to hear with impartiality, to examine and judge for yourselves, enough has been said to apprize you of those avenues at which the enemies of truth and justice are most likely to enter, and most easily to beset you.”
