But large as was the assembly thus occupied in the upper part of the City in rendering the last tribute of respect to the loved and lost; a still larger number had collected in the neighborhood of the Committee Rooms in the lower part to witness a solemn act of retribution. They swarmed upon the housetops, filled windows, and such, portion of the streets as was open to them, and from which they could obtain a view of the proceedings, and waited in anxious expectation the infliction of the penalty of their crimes upon the two assassins in the hands of the Committee. From an early hour in the morning, movements in and around the Rooms had plainly indicated the purpose for which they were made. Riflemen were stationed on the roofs of the Committee building and those adjoining. A detachment was sent out, which cleared and thoroughly searched a building opposite. Cannon were placed at points to command and sweep the streets in the vicinity. Cavalry patrolled in all directions, and large bodies of infantry were gradually placed in position, and formed an immense square enclosing the entire block, and allowing no new approach to the Rooms. Ominous preparations were also making in the building by projecting from two of the second story windows in front, platforms with, hinges just beyond the window sills, supported by ropes running to the roof of the building.
At a quarter past one, as the funeral procession was leaving the church on Stockton Street the two offenders against the law of God and man were placed upon the scaffolds, and, after a few words from Casey, denying repeatedly that he was a murderer, as charged by the Alta California and other papers, on the ground that he had been taught always to revenge an insult or injury, a signal was given and the unhappy men instantly passed to their account. The whole body of the military, and many of the other spectators stood uncovered and in profound silence and awe, while this stern and solemn People’s tragedy was enacting. Late in the afternoon the entire force of armed citizens was drawn up in line on Sacramento Street presenting a most imposing array; were reviewed by the Commander, and then marched by companies to the Rooms, deposited their arms, and, with the exception of guards detailed for further duty, amounting to some three hundred men, were dismissed.
