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.

CAFE RESTAURANT, SAN FRANCISCO—MADE OUT OF A SHIP GALLEY.

From J and Third, the fire curled around Scudder & Carroll's, and extended to Dr. Morrell's drug store, on the south side of J street, which proved a barrier for a time. These buildings, of wood, were built in 1849, and as combustible as powder. The flames caught the wooden building opposite, and spread to the rear on I street. At this time, W. R. McCall & Co.'s building caught on the roof. The burning of their building sealed the fate of all to the levee, on both sides of the street, and bearing down the length of the city, the flames extended, soon wrapping the Orleans Hotel. The buildings all around were blown up with the rapidity of magic, carts standing ready with 25lb. kegs of powder. The Union office next fell, the proprietors saving two presses, type and paper sufficient for a few days' supply. The Tahama block, containing Page, Bacon & Co.'s, Swift's and Grimes' banking offices, saved, wind changing, blowing directly south from them. J. B. Starr's store also made a wall to prevent the further spread of the fire in that direction. At this moment the fire reached, from the levee, J and K street to Tenth, one sea of fire, crumbling every thing to ashes. The large brick store of J. A. Haines, the brick blocks on K—with the exception of that of the Lady Adams Co. on K, between First and K streets—are a pile of ruins. The L. A. Co.'s buildings stand prominent and erect this morning, a monument to the proprietor's sagacity and good sense. The families on the line below K street, were busy removing their valuables and furniture, when the flames crossed the brick barrier, and swept with remorseless fury down and across, licking with its forked tongue from street to alley, apparently shrivelling the wooden buildings with a single breath. The inmates of the hospital, seventy in number, were taken in season to the levee, and from thence to a suitable house, by Drs. Briarly and Williams. The City market, filled with hay, and the hospital, were the last on that line of the fire, where the citizens effectually stopped its further progress. On F street the brick building of Reynolds & Co. made but a light barrier, the roof falling in almost immediately, with three of No. 3's engine men, who were burned to death. Every thing to Eighth street, on the north, and Ninth Street on the south side of J street to Twelfth street, on K down to N street on the southeast, through N and M to the levee—the El Dorado, supposed impregnable hitherto, as also Merritt's, Dr. Morrill's, Scudders', and Case & Co.'s are completely gutted.

Thus far the number of lives ascertained to be lost are six. Three of No. 3's Engine Company's men, who fell with the roof of Reynolds & Co.'s building, were swallowed up alive; the confusion of the morning, and the scattering of people, prevented a roll call to ascertain the names of the gallant but unfortunate firemen. A lady, next door to the place where the fire originated, is also reported burnt. The number scorched is enormous, all of whom, however, are carefully attended to by surgeons on board the Camanche. Every assistance possible was proffered by the captains and agents of the steamers, whose vessels were soon crowded with females. The levee was strewn with merchandise of every description, and the wind blowing from the northwest threw the sparks from the goods and saved them all. At 5 A.M., the fire had nearly ceased, the smouldering embers throwing huge clouds of smoke and lurid flashes, bringing desolation to the hearts of all who witnessed the sickening sight. The losses cannot be less than $5,000,000.

On the evening of the 9th of November, another great fire occurred at San Francisco. Of this the California Whig of Nov. 10, gives the following account:—

Last evening, at half past eight o'clock, our citizens were alarmed by the dreadful cry of fire, which proved to be too well founded, for in less than five minutes the whole city was illumed by the lurid glare of the flames.
