270 ZJTJRtf ON TH£ MISSISSIPPI. I mean. 3Tor you will have come to know, with a deep and restful cer- tainty, that you are not going to meet two people sick of the same theory, one right after the other. !No, there will always he one or two with the other diseases along between. And as you proceed, yon will JEind out one or two other things. You will find out that there is no distemper of the lot but is contagious; and you cannot go where it is without catching it. You may vaccinate yourself with deterrent facts as much as you please—it will do no good; it will seem to * take/ but it doesn't; the moment you rub against any one of those theorists, make up your mind that it is time to hang out your yellow flag.

Every man on the river banks, south of Cairo, talks about it every day, during such moments as he is able to spare from talking about the war ; and each of the several chief theories has its host of zealous partisans; but, as I have said, it Is not possible to determine which cause numbers the most recrtxxts. All were agreed upon one point, however: if Congress would a sufficient appropriation, a colossal benefit would result. Very ; since then the appropriation has been made—possibly a suffi- OM, certainly not too large a one. Let us hope that the pro- pfeeey Trill be amply fulfilled. One thing will be easily granted by the reader; that an opinion Mr. Edward Atkinson, upon any vast national commercial r, comes as near ranking as authority, as can the opinion of any
