A convention of the quartz miners of Nevada county was to have been held at Nevada on the 13th of November, to adopt measures having for their purpose more unity of operation and greater security of labor and capital.

The San Francisco papers of Jan. 1, 1853, contain most interesting intelligence of the state of the gold region. The following is the most important:—

The present winter is conceded to be the most severe experienced in this country since it has been populated by Americans. During the last fortnight it has been raining and snowing continually in the mountains and valleys, and we are daily in the receipt of accounts of disasters and suffering in all parts of the state. The waters have been unusually high, and communication through the mining regions almost entirely cut off, either by snow or overflowed streams. The rivers have been swelled to such an extent as to inundate all the low lands, causing immense damage, destroying stock and agricultural products.

The whole country between Tehama and Sacramento city was entirely under water, whilst Marysville was partly inundated, and though Sacramento city was well protected by a levee, the lower portions were submerged. The waters at the present time have subsided, although the rains still continue. On the mountain streams, the loss of mining implements has been great, and all work for the present is suspended. Bridges have been swept away, and ferries destroyed, and some few lives lost. The southern portion of the mining district has suffered equally with the northern. Stockton has been inundated partially, and property to a considerable amount destroyed. The bridges on the Calaveras, Stanislaus, and other streams have been swept away, and communication with the mining towns for a while suspended. The flood has been universal, and the waters higher than in the memorable winter of 1849.

The great scarcity of provisions, and the consequent high prices, have occasioned much suffering and distress already, and it is feared that many will actually die from starvation. Many miners subsist entirely on beef and potatoes, whilst in other portions of the mines there are hundreds who have nothing at all but barley and potatoes. In portions of Yuba and Sierra county the snow was already ten feet deep, and still falling, and the miners actually reduced to absolute want.

In one place they held a meeting and forced a trader to sell what flour he had on hand at 45 cents per pound, and all who were able to leave did so, thus leaving the provisions for those who were unable to find their way through the snows to the valleys. In some places cabins are entirely covered with snow, and the roofs of many have been crushed in, thus cutting off the last chance of protection. The accounts received may be greatly exaggerated—nevertheless, there is much suffering and distress, and it is not improbable that some may perish by starvation.

A few days since, we were visited with a terrible southeast gale, which prevailed for two days. Several light tenements were blown down, and some injury done to the shipping in the harbor. For a day or two, communication by stage with San Jose was cut off, owing to the sudden rise of the intermediate streams.

Several important decisions have been rendered in our courts, among which is the decision of the State Supreme Court, recognizing the right of native claimants of land to the summary remedy of ejectment where they are disturbed by squatters. This applies to parties who are in possession of their claims, and relieves them from what, by a previous decision of the court, was a necessity, that they should incur first the expensive process of a writ of right in order to prove their title.

The Land Commission are making considerable progress in the adjudication of claims. Of these, the most important, perhaps, is that of Mr. Fremont, to a large tract of land on the head waters of the Mariposa river. The Commission recognizes his claim to the land, but does not undertake to decide upon his title to the mineral wealth, which, as is well known, is embraced within the limits of the grant.

A convention of Quartz Miners, held at Nevada, have adopted a code of laws for the government of those working quartz veins in that country.
