These are the people among whom the practice that is called _a mock_, or running a muck, has prevailed for time immemorial. It is well known, that to run a muck in the original sense of the word, is to get intoxicated with opium, and then rush into the street with a drawn weapon, and kill whoever comes in the way, till the party is himself either killed or taken prisoner; of this several instances happened while we were at Batavia, and one of the officers, whose business it is, among other things, to apprehend such people, told us, that there was scarcely a week in which he, or some of his brethren, were not called upon to take one of them into custody. In one of the instances that came to our knowledge, the party had been severely injured by the perfidy of women, and was mad with jealousy before he made himself drunk with opium; and we were told, that the Indian who runs a muck is always first driven to desperation by some outrage, and always first revenges himself upon those who have done him wrong: we were also told, that though these unhappy wretches afterwards run into the street with a weapon in their hand, frantic and foaming at the mouth, yet they never kill any but those who attempt to apprehend them, or those whom they suspect of such an intention, and that whoever gives them way is safe. They are generally slaves, who indeed are most subject to insults, and least able to obtain legal redress: freemen, however, are sometimes provoked into this extravagance, and one of the persons who run a muck while we were at Batavia, was free and in easy circumstances. He was jealous of his own brother, whom he first killed, and afterwards two others, who attempted to oppose him: he did not, however, come out of his house, but endeavoured to defend himself in it, though the opium had so far deprived him of his senses, that of three muskets, which he attempted to use against the officers of justice, not one was either loaded or primed. If the officer takes one of these amocks, or mohawks, as they have been called by an easy corruption, alive, his reward is very considerable, but if he kills them, nothing is added to his usual pay; yet such is the fury of their desperation, that three out of four are of necessity destroyed in the attempt to secure them, though the officers are provided with instruments like large tongs, or pincers, to lay hold of them without coming within the reach of their weapon. Those who happen to be taken alive are generally wounded, but they are always broken alive upon the wheel, and if the physician who is appointed to examine their wounds, thinks them likely to be mortal, the punishment is inflicted immediately, and the place of execution is generally the spot where the first murder was committed.
