Revolutions are matters of frequent occurrence in California.  They are got up by men who are at the foot of the ladder and in desperate circumstances, just as a new political organization may be started by such men in our own country.  The only object, of course, is the loaves and fishes; and instead of caucusing, paragraphing, libelling, feasting, promising, and lying, they take muskets and bayonets, and, seizing upon the presidio and custom-house, divide the spoils, and declare a new dynasty.  As for justice, they know little law but will and fear.  A Yankee, who had been naturalized, and become a Catholic, and had married in the country, was sitting in his house at the Pueblo de los Angeles, with his wife and children, when a Mexican, with whom he had had a difficulty, entered the house, and stabbed him to the heart before them all.  The murderer was seized by some Yankees who had settled there, and kept in confinement until a statement of the whole affair could be sent to the governor-general.  The governor-general refused to do anything about it, and the countrymen of the murdered man, seeing no prospect of justice being administered, gave notice that, if nothing was done, they should try the man themselves.  It chanced that, at this time, there was a company of some thirty or forty trappers and hunters from the Western States, with their rifles, who had made their head-quarters at the Pueblo; and these, together with the Americans and Englishmen in the place, who were between twenty and thirty in number, took possession of the town, and, waiting a reasonable time, proceeded to try the man according to the forms in their own country.  A judge and jury were appointed, and he was tried, convicted, sentenced to be shot, and carried out before the town blindfolded.  The names of all the men were then put into a hat, and each one pledging himself to perform his duty, twelve names were drawn out, and the men took their stations with their rifles, and, firing at the word, laid him dead.  He was decently buried, and the place was restored quietly to the proper authorities.  A general, with titles enough for an hidalgo, was at San Gabriel, and issued a proclamation as long as the fore-top-bowline, threatening destruction to the rebels, but never stirred from his fort; for forty Kentucky hunters, with their rifles, and a dozen of Yankees and Englishmen, were a match for a whole regiment of hungry, drawling, lazy half-breeds.  This affair happened while we were at San Pedro (the port of the Pueblo), and we had the particulars from those who were on the spot.  A few months afterwards, another man was murdered on the high-road between the Pueblo and San Luis Rey by his own wife and a man with whom she ran off.  The foreigners pursued and shot them both, according to one story.  According to another version, nothing was done about it, as the parties were natives, and a man whom I frequently saw in San Diego was pointed out as the murderer.  Perhaps they were two cases, that had got mixed.
