During our protracted absence of 14 months, in the course of which we had necessarily been exposed to great varieties of weather and of climate, not one case of sickness had ever occurred among us.

Here ended our land journey; and the day following our arrival, we found ourselves on board a steamboat rapidly gliding down the broad Missouri. Our travel-worn animals had not been sold and dispersed over the country to renewed labor, but were placed at good pasturage on the frontier, and are now ready to do their part in the coming expedition.

On the 6th of August we arrived at St. Louis, where the party was finally disbanded, a great number of the men having their homes in the neighborhood.

Andreas Fuentes also remained here, having readily found employment for the winter, and is one of the men engaged to accompany me the present year.

Pablo Hernandez remains in the family of Senator Benton, where he is well taken care of, and conciliates good-will by his docility, intelligence, and amiability. General Almonte, the Mexican minister at Washington, to whom he was of course made known, kindly offered to take charge of him, and to carry him back to Mexico; but the boy preferred to remain where he was until he got an education, for which he shows equal ardor and aptitude.

Our Chinook Indian had his wish to see the whites fully gratified. He accompanied me to Washington, and, after remaining several months at the Columbia College, was sent by the Indian department to Philadelphia, where, among other things, he learned to read and write well, and speak the English language with some fluency. He will accompany me in a few days to the frontier of Missouri, where he will be sent with some one of the emigrant companies to the village at the Dalles of the Columbia.

Very respectfully, your obedient servant, J. C. FREMONT, Bt. Capt. Topl. Engineers.


GOLD REGIONS OF CALIFORNIA.

The "placers" or Gold Mines of California, are located in the valley of the Sacramento, in the northern part of that new territory. They are all on the public lands, with the exception of the portion belonging to Messrs. Forbes and Sutter. The region which they embrace and which lies, according to authentic reports, on both sides of the Sierra Nevada, must be "larger than the State of New York." The mines, it is estimated, are worth a thousand millions of dollars. The most reliable information in regard to them may be found in the official reports communicated to the authorities at Washington, by some of the American officers who have visited the region. The following document is of this nature. The author of it, Col. Mason, the military commander in California, speaks, as will be seen, from observation, and the fullest confidence may be placed in his account:--
