In the mountain district of the Neveda range, the climate was describd in the geography of that portion of California.

Lower down and westward, along the great valley, the climate is milder, through the whole of the year. I believe the large rivers of the valley are not frozen during the winter, and the weather in summer is quite warm. Thus far from the axis of the Neveda mountains eastward, to the two great rivers westward, during the summer season, the sky is serene, and the stars and planets shine with great splendor.

No dew falls in that part hitherto describd, during the hottest season of the year, and travelers may lie upon the ground without exposure from the unhealthiness of a damp ground and a moist atmosphere.

Farther outward, and along the coast, the country is much of the time during the year, coverd with fogs, which render it unpleasant, and in some measure unhealthy. The town of San Francisco, most of the year, is envelopd in a thick fog, during much of the night and the following day, till 10 or 11 o’clock, after which time the wind becomes of sufficient strength to clear away the fog, which often renders the remainder of the day unpleasant. This town, from the almost continued dampness of the atmosphere, and the unavoidable use of mineralizd water, can hardly be considerd a healthy place. Dysentery and fever seems to be the prevalent disease.

I had nearly forgotten an idea which I now recollect to have heard, relating to the dryness and purity of the atmosphere of California. It has been said that the flesh of animals may be hung up in the open atmosphere, till it becomes perfectly preservd by drying, without salt, and during such process, no annoying insects ever disturb it—and also, that a man would never die there, except by being dried up.

It is true, that the Spaniards have a mode of preserving the flesh of the ox, by cutting it into very small strips, and hanging it upon strings cut from the raw hide, where it is exposd to the heat of the sun. In this way, meat could be preservd in any of the States, but if it be left in large masses, and so circumstancd that any part of it is kept from drying immediately on the outside, the green fly, an insect common to that country as well as the States, is presently found to be a loathsome intruder.

When I left the mining district for the valley, on my way to San Francisco, on the 13th of October, I saw eight or ten vessels lying at Stocton, and at the head of Suisan bay, three or four more, and at the head of Pablo bay, six or seven more. These, with ten or twelve lying at Sacramento city, and as many more scatterd along the two rivers and in the several bays, added to about 130 which I counted in the harbor of San Francisco, on my arrival there, will make about 175 vessels within the country of California. Most of the vessels lying in the harbor of San Francisco, were inactive, for want of help to work them.

The business of transportation upon the two rivers, St. Waukeen and Sacramento, I believe to be as profitable as any that is attended to in California. When I left, two small steamers were constantly plying between San Francisco and Sacramento city, and another was being put together at Suisan bay, for the navigation of the St. Waukeen. More busines at present is done upon the rivers by launches, a small vessel of only one mast, than by any other vessel. These are more easily managd than large ships, along the intricate windings of those extremely crooked rivers, but so soon as a sufficient number of steamers can be obtaind for the business of the rivers, other means of transportation will in a great degree cease.
