"Labor has ever been high in California, but previous to the discovery of the _placera_ gold, the rates ranged from $1 to $3 per day. Since that epoch common labor cannot be obtained, and if to be had, for no less price than fifty cents per hour, and that the most common. Carpenters and other mechanics have been offered $15 a day, but it has been flatly refused. Many of our enterprising citizens were largely engaged in building, and others wish to commence on dwellings, warehouses, and the like, but all have had to suspend for the lack of that all important class of community, the working men." The following extracts from the published journal of a physician in California, give accounts of the reception of the news of the gold discovery in San Francisco, with its consequent effects. "_May 8th._--Captain Fulsom called at Sweeting's to-day. He had seen a man this morning, who reported that he had just come from a river called the American Fork, about one hundred miles in the interior, where he had been gold washing. Captain Fulsom saw the gold he had with him; it was about twenty-three ounces weight, and in small flakes. The man stated that he was eight days getting it, but Captain Fulsom hardly believed this. He says that he saw some of this gold a few weeks since, and thought it was only 'mica,' but good judges have pronounced it to be genuine metal. He talks, however, of paying a visit to the place where it is reported to come from. After he was gone, Bradley stated that the Sacramento settlements, which Malcolm wished to visit, were in the neighborhood of the American Fork, and that we might go there together; he thought the distance was only one hundred and twenty miles. "_May 10th._--Yesterday and to-day nothing has been talked of but the new gold 'placer,' as people call it. It seems that four other men had accompanied the person Captain Fulsom saw yesterday, and that they had each realized a large quantity of gold. They left the 'diggings' on the American Fork, (which it seems is the Rio de los Americanos, a tributary to the Sacramento) about a week ago, and stopped a day or two at Sutter's Fort, a few miles this side of the diggings, on their way; from there they had travelled by boat to San Francisco. The gold they brought has been examined by the first Alcalde here and by all the merchants in the place. Bradley showed us a lump weighing a quarter of an ounce, which he had bought of one of the men, and for which he gave him three dollars and a half. I have no doubt in my own mind about its being genuine gold. Several parties, we hear, are already made up to visit the diggings; and, according to the newspaper here, a number of people have actually started off with shovels, mattocks, and pans, to dig the gold themselves. It is not likely, however, that this will be allowed, for Captain Fulsom has already written to Colonel Mason about taking possession of the mine on behalf of the government, it being, as he says, on public land.
