In the middle of June, there was much excitement in San Francisco, caused by the reported discovery of a gold lake, among the mountains between the South Fork of Feather River and the Yuba. One man was said to have got $7000 in four days, and a party of ten Kanakas were reported to have got $75,000 in a week. A vast number of people were by this means attracted to the sources of the Feather and Yuba Rivers, and though they found the lake story a hoax of a vile character, they found tolerably fair diggings, which would console them for their disappointment.

The following extract from the Placer Times of the 17th of July, 1850, under the head of "Great Discoveries of Gold—Gold Lake," will afford the reader a lively conception of the degree of excitement caused in California by every new announcement of a newly discovered locality abounding in gold:

"We were inclined to give only an average degree of credit to stories that have reached us during the past few days, of the unprecedented richness which this locality has developed. A few moments passed in Marysville on Saturday, convinced us that there is much more show of reality in this last eureka report, than usually attaches to the like. In a year's experience of local excitements from the same cause, we have seen none equal to what now prevails in that town. It has visited all the inhabitants indiscriminately, lawyers, doctors and judges, traders, teamsters, mechanics and gamblers. Our readers know we are the last to justify the circulation of unfounded or exaggerated reports, but we deem it right to conceal nothing of what may prove (for aught that we can see to the contrary) one of the most astounding discoveries in the modern history of diggings. The specimens brought into Marysville are of a value from $1600 down. Ten ounces is reported as no unusual yield to a panfull, and the first party of sixty, which started out under the guidance of one who had returned successful, were assured that they would not get less than $500 each per day. We were told that the previous morning two hundred had left the town with a full supply of provisions and four hundred mules. Those who could not go were hiring others in their stead. The length of the journey and the quantity of provisions required, there being no stores in the region, rendered an outfit rather expensive. Mules and horses had doubled in value, and $400 were considered no more than enough to furnish a proper start.

The distance to Gold Lake was first reported two hundred miles; the best informed, however, say that it is but little more than half of that. It lies at a very considerable elevation among the mountains that divide the waters of the South Fork of Feather from those of the north branch of the Yuba. The direction from Marysville is a little north of east. The story has of course spread ere this far and wide among the miners high up on the Feather and Yuba, and the spot will be as crowded as all other good places are, ere the tardy adventurer from this region could reach it. The region of the Gold Lake wonders is a new one, however, and lies between what are established to be diggings of unsurpassed richness. It is our belief that it is better for one who has got some initiation into the gold mysteries, (if there be any,) not to be content in old 'used up' localities, but to push along to the great field yet unexplored; and that, though the search be long and laborious, the big lift is ultimately pretty sure for those who are patient and persevering."

MONTEREY.

The same paper of July 18th, contains additional particulars, having a tendency to add plausibility to the reports. Among other things, a man by the name of McLelland came into Marysville on the 17th, with $7000, the result of four days' labor at Gold Lake. Whatever may be the truth of the reports, there is no doubt of one thing—the whole population of Marysville and its vicinity have become infected by the news, and are taking up their march thitherwards in crowds.

The Transcript speaks rather doubtingly on the subject; it says—"The reports come as a general thing, through teamsters and other persons whose interest it is to give as favorable accounts as possible. The statements are very conflicting."

To this we may add the statement of a gentleman who reached this city from Marysville, direct, on Tuesday night. The excitement, he says, is great; but no one could give any definite information of the locality or of its productiveness. Yet all seemed to think there was no doubt in the matter, and as many as could get away were starting, or getting ready to push for the new El Dorado. Upon his way down, on board the boat, he conversed with a man who professed to have explored that region lately, although he did not claim to know where Gold Lake was. But between the North Fork of the Yuba and Feather Rivers, at the foot of the great chain of mountains, he reported a series of lakes of various dimensions, and "two thousand people," prospecting all about. The snow was very deep—"six feet"—and but little gold.

The following extract from the Placer Times, is the most positive information within our knowledge.
