The fire burnt eastward to the buildings of Messrs. Austin & Lobdell, fronting on Clay street, and that of Mr. Naglee, fronting on Merchant street. On the north side of Merchant it took the Union Hotel, and all the buildings fronting on that street, down towards Montgomery, to Bolton and Barron's building. It did not cross over to Washington in any instance. This is the second time that the building of Messrs. Austin & Lobdell has proved an effectual barrier to the progress of a fire, and without receiving the least injury itself, or damaging the goods within it. Nothing but the determined and unparalleled efforts of the firemen prevented the fire from extending to the south side of Clay street; as it was, some $10,000 damage was done to goods and buildings upon that side. The fire broke out, as we have said, at half past eight o'clock, and it was not until a quarter past ten that it was checked or its further spread prevented, and the engines worked for some time longer. The records of the different courts in the old City Hall were removed, but thrown into the utmost confusion. In the midst of the excitement, Mr. Masalski, a gentleman well known to the community as the former keeper of the Sacramento House, rushed to the scene of disaster, and shortly afterwards returned to his dwelling. He was immediately seized with the most alarming symptoms, and in a few moments breathed his last. Dr. Guatier, who attended him in his last moments, says that it is difficult to pronounce upon the cause of his death, other than that it was brought about by congestion of the brain, but what was the immediate cause of this congestion he is unable to say at present. It is of course impossible for us to give a correct estimate of the losses sustained, but we have heard it variously estimated as from $150,000 to $200,000. Other destructive fires occurred at Marysville, Sonora, Stockton, San Diego and in the agricultural districts, an immense amount of property being destroyed. In the cities, the damage was repaired, with an astonishing rapidity, but some individuals were utterly ruined--the results of years of labor being swept away in a single night. The cities of California are now generally supplied with fire engines and hook and ladder companies. But these machines are not always available. The mining news contained in California papers of November, 1852, is very interesting.
