Linkin has been nigh about down sick with the fever an ager. Of course it wouldn't do to let the tel-lie-graf git hold of it, for it would scare Wall street in spasms, and knock stocks down wus than the retreat of Ginneral McClellan. So Stantin put his sensership on the news, an that was the end of it, while I went to work as I could to cure the Kernel up. You see, the Kernel, for the last month or so, has been very much broke of his sleep. Sumtimes he's up nigh about the hull nite consulten with Stantin, an Hallick, an Seward, an the nite air has been too much for him. The banks of the Potomick in July an August are mity hard on the constitushin, an ef there is any bilyusness in a man, its purty sure to bring it out. Linkin says his constitushin is just like the war, so far, nigh about all _bill_yus. One day I went into the Kernel's room, an seein he looked kinder blue about the gills, ses I, "Kernel, what's the matter?" Ses he, "Majer, I feel as cold as a frozen turnip." Ses I, "Kernel, ain't you gettin the ager?" Ses he, "No, Majer, I don't think I'm gettin it, for I've got it already." "Wal," ses I, "Kernel, ef there is eny feller on arth who can cure the fever an ager, it's me." "Wal," says he, "Majer, I wish you would go ahead, for I can't afford to be sick now. The truth is, ef I had a good ax an some chestnut timber I could soon work off the shakes myself. I used to have them when I was a boy, powerful bad, but I could jest go out eny mornin and break an ager by splitting up a hundred rails as a breakfast spell; but now I s'pose I must dose myself with some sort of pizen doctor stuff, just because it wouldn't look well for a President to split rails." "No," ses I, "Kernel, you needn't take eny pizen stuff. I'll fix you sum medecin which was a grate favorite with Ginneral Jackson, an it will cure you up as sure as my name's Downing." Ses he, "What is it?" Ses I, "It's elder bark tea." So I jest went to work and got the feller in bad close, who does chores around the White House, to go out into the sububs an scrape me sum bark. I told him very particaler how to do it, an to be very kerful an not to scrape it roundabout-ways of the wood. You see, elder bark is the queerest stuff in the world. If you scrape it down it acts as a fisic, an if you scrape it upwards it becomes an emetick, while by scrapin it around-ways, it ain't nuther one thing nor tother, but just raises a young arthquake gripin an panein a feller as ef the cholery, an yaller fever, an kronick rumatiz
