The following letter was found upon the table near the late Damien Marchesseault, addressed to Mrs. Marchesseault; and was place in our hands for publication by the friends of that lady:Office of the City Marshal, Los Angeles City, January 20, 1868.My Dear Mary: - By my drinking to excess, and gambling also, I have involved myself to the amount of about three thousand dollars which I have borrowed from time to time from friends and acquaintances. Under the promise to return the same the following day, which I have often failed to do. To such and extend have I gone in this way that I am now ashamed to meet my fellow man on the street; besides that, I have deeply wronged you as a husband, by spending my money instead of maintaining you as it become a husband to do. Though you have near complained of my miserable conduct, you nevertheless have suffered too much. I therefore, to save you from farther disgrace and trouble, being that I cannot maintain you respectably, I shall end this state of thing this very morning. Of course, in all this, there is no blame-attached contrary you have asked me to permit you to earn money honestly by teaching and I refused. You have always been true to me. If I write these few lines, it is to set you a night before this wicked world, to keep slander from blaming you in way manner whatever. Now, my dear beloved, I hope that you will pardon me, and also Mr. Sainsevain. It is time to part, God bless you, and may you be happy yet, your husband Damien Marchesseault.
