Your friends here—and you may be satisfied you have "some" in these diggings—are delighted at beholding such an evidence of prosperity as the advent of your large and beautiful Weekly—which I submitted this morning, to the inspection of a knot of our craft, and of journalists, who all pronounced it a model newspaper. I hope you will keep up the character of variety which appears in it, and which is as much the spice of a newspaper, as of life. You needn't blush when I tell you that among good judges here, the Crescent is considered to be the best Daily in the south-west. Moreover, you know, print people are not over-fond of praising their contemporaries; and don't do it without strong cause.

The great topic of interest here (since the election is settled) appears to proceed from the existence of the cholera, which has arrived at last, sure enough. Thus far it has been kept at the Quarantine station on Staten Island, about seven miles below the city. Some three of four cases were landed from the Liverpool liner New York, a week ago; they were bedded in a large room, where there were several other sick persons. As others were landed, they went in the same room. But not many hours elapsed before some of the other sick persons exhibited symptoms of cholera too. The doctors, however, (who, as a class, are the most self-opinioned creatures under the sun,) wouldn't separate the original patients, till the spread of the disease threatened alarming consequences. They did separate them, though, at last, and put the cholera patients in an isolated place, by themselves. Since that time, the disease has spread little or none. From the best information, there have been about twenty cases; and half of these have resulted fatally. It must be borne in mind, at the same time, that most of these cases were of persons who were in all likelihood debilitated by disease or dissipation, and their systems sank under the exhausting drain of cholera. The weather, too, has been remarkably bad, for health. For the last three days—during Wednesday, Thursday and Friday—the air has been filled with a heavy, stagnated, foggy wetness, and the streets with mud and filth, and every object covered with clammy moisture. Of course, too, nearly every disease is now, through the popular alarm, converted into cholera.

We shall soon see how all this will change when there comes a dry, keen frost. I know the cry is that weather makes no great difference in the spread of the dreaded disease; but that is nonsense. When the nature of the atmosphere is completely changed, and exhalations are not developed, it looks likely that the same effects will ensue as from totally different causes!

Our young men are in some commotion, induced by the golden realities of California; and there is talk of fitting out ships, and much people going in them, to hoe up the gold. What splendid visions! and how much more reliable, too, than splendid visions usually are! Havn'tHaven't you felt a "call" toward those shores which so

"Pour down their golden sands,"

that people gather them by the tin cup-full? I must say I should have no sort of objection to go if I were'ntweren't "tied down," in New York. Let us hope that the yellow tide will have to set this way, (through New Orleans, of course,) and that editors and printers and newspaper correspondents, may get some of it, with the rest.

As the river continues navigable, and the canals ditto, produce of all kinds remains low in price and plentiful in quantity. The latter part of yesterday afternoon was oppressively warm—and this on the 8th of December! One of the papers wittily says the telegraph has brought on a dispatch of Southern weather....The Simpson benefit was very largely attended on Thursday night; I am informed it will yield $1400 or $1500 profit. The play and performances generally were well sustained.....Exhibitions of various kinds—pictures and other works of art among the rest—are now very well patronized in New York. The proprietors of nearly all these places are making money....It is every way likely the plan of the "Battery enlargement" will be favorably decided upon before long. You won't know the old spot, then, it will be so much bigger.

Brooklyn, where it was burnt up—and that was about five acres of its best part—is being rapidly rebuilt again, with wider streets, and more substantial houses.
