It is the prevailing opinion that this movement originated in a mere restless spirit of adventure. But there are some sagacious statesmen at Washington and some keen-eyed politicians in California, who regard it as having had the object of organizing a powerful French state, which might check the progress of the great North American confederacy. Senator Bell, of Tennessee, predicted that such a design would be entertained, and such a movement executed by the French. It is well that the people of California should be upon their guard. A republic can have no safe neighbors but republics. There are a large number of Frenchmen in California; but if the Americans are vigilant there is nothing to be feared from them. On the 2d of November, 1852, the presidential election was held throughout the United States. The Democrats carried California for their electoral ticket, pledged to vote for Franklin Pierce, of New Hampshire, and William R. King, of Alabama. The state election occurred at the same time, and in this, also, the Democrats were completely successful. About the same time, destructive fires occurred in various parts of California. The greater part of the city of Sacramento was laid in ashes by a conflagration, which occurred on the 2d of November. Of this terrible disaster, the San Francisco Herald of the 4th of November, gives the following account:-- At 11½ o'clock on Tuesday evening, a fire broke out in the millinery shop of Madam Lanos, on J street, near the corner of Fourth. The inspectors were counting the votes, and a numerous crowd were awaiting the decision of the judges, so that no time was lost in delay. With astonishing rapidity the fire spread from building to building--up, down and across the street, in five minutes. The Crescent City Hotel, on the opposite side of the street, was in flames, and being of inflammable materials and of large size, sent the fiery torrent in every direction. The hardware store of Pawoth, Eels & Co. communicated the flames to the brick block adjoining, which was speedily burned to the ground, and carried the fire up street on both sides, until it reached Eighth street, and on the south side of J street. On the corner side, from Brown, Kenny & Co.'s brick block, which caught from the Crescent City fire, there was nothing to stay its progress but the Overton Block, on the corner of Third and J streets, on the one side, and Scudder, Carroll & Co. on the other. For a time the superhuman exertions put forth seemed to check, and it was hoped would entirely subdue the fire, and the boom of the powder, like artillery, that was deposited in every building, by the hook and ladder boys, was deemed the signal for the arrest and staying of the fire on this line. In vain, however; the wind, heretofore blowing towards the levee, increased to a gale and changed to the north, thus turning the fire broadside on, and in five minutes it had spread to M. street.
