Raish sends regards. He or I, one will drop a line to the “Age” occasionally. I suppose you saw my letters in the “Enterprise.” Yr. BRO, SAM P. S. I suppose Pamela never will regain her health, but she could improve it by coming to California--provided the trip didn't kill her. You see Bixby is on the flag-ship. He always was the best pilot on the Mississippi, and deserves his “posish.” They have done a reckless thing, though, in putting Sam Bowen on the “Swan”--for if a bomb-shell happens to come his way, he will infallibly jump overboard. Send me another package of those envelopes, per Bagley's coat pocket. We see how anxious he was for his brother to make a good official showing. If a niggardly Government refused to provide decent quarters--no matter; the miners, with gold pouring in, would themselves pay for a suite “superbly carpeted,” and all kept in order by “two likely contrabands”--that is to say, negroes. Samuel Clemens in those days believed in expansion and impressive surroundings. His brother, though also mining mad, was rather inclined to be penny wise in the matter of office luxury--not a bad idea, as it turned out. Orion, by the way, was acquiring “feet” on his own account, and in one instance, at least, seems to have won his brother's commendation. The 'Enterprise' letters mentioned we shall presently hear of again. To Orion Clemens, in Carson City: ESMERALDA, Sunday, May--, 1862. MY DEAR BROTHER,--Well, if you haven't “struck it rich--” that is, if the piece of rock you sent me came from a bona fide ledge--and it looks as if it did. If that is a ledge, and you own 200 feet in it, why, it's a big thing--and I have nothing more to say. If you have actually made something by helping to pay somebody's prospecting expenses it is a wonder of the first magnitude, and deserves to rank as such. If that rock came from a well-defined ledge, that particular vein must be at least an inch wide, judging from this specimen, which is fully that thick. When I came in the other evening, hungry and tired and ill-natured, and threw down my pick and shovel, Raish gave me your specimen--said Bagley brought it, and asked me if it were cinnabar. I examined it by the waning daylight, and took the specks of fine gold for sulphurets--wrote you I did not think much of it--and posted the letter immediately. But as soon as I looked at it in the broad light of day, I saw my mistake. During the week, we have made three horns, got a blow-pipe, &c, and yesterday, all prepared, we prospected the “Mountain House.” I broke the specimen in two, and found it full of fine gold inside. Then we washed out one-fourth of it, and got a noble prospect. This we reduced with the blow-pipe, and got about two cents (herewith enclosed) in pure gold.
