The reader of the American Notes will remember the admirable and most humorous description of the night steamer on the Potomac, and of the black driver over the Virginia road. Both were in this letter; which, after three days, he resumed "At Washington again, Monday, March the twenty-first:

"We had intended to go to Baltimore from Richmond, by a place called Norfolk; but, one of the boats being under repair, I found we should probably be detained at this Norfolk two days. Therefore we came back here yesterday, by the road we had traveled before; lay here last night; and go on to Baltimore this afternoon, at four o'clock. It is a journey of only two hours and a half. Richmond is a prettily situated town, but, like other towns in slave districts (as the planters themselves admit), has an aspect of decay and gloom which to an unaccustomed eye is most distressing. In the black car (for they don't let them sit with the whites), on the railroad as we went there, were a mother and family, whom the steamer was conveying away, to sell; retaining the man (the husband and father, I mean) on his plantation. The children cried the whole way. Yesterday, on board the boat, a slave-owner and two constables were our fellow-passengers. They were coming here in search of two negroes who had run away on the previous day. On the bridge at Richmond there is a notice against fast driving over it, as it is rotten and crazy: penalty—for whites, five dollars; for slaves, fifteen stripes. My heart is lightened as if a great load had been taken from it, when I think that we are turning our backs on this accursed and detested system. I really don't think I could have borne it any longer. It is all very well to say 'be silent on the subject.' They won't let you be silent. They will ask you what you think of it; and will expatiate on slavery as if it were one of the greatest blessings of mankind. 'It's not,' said a hard, bad-looking fellow to me the other day, 'it's not the interest of a man to use his slaves ill. It's damned nonsense that you hear in England.'—I told him quietly that it was not a man's interest to get drunk, or to steal, or to game, or to indulge in any other vice, but he did indulge in it for all that; that cruelty, and the abuse of irresponsible power, were two of the bad passions of human nature, with the gratification of which, considerations of interest or of ruin, had nothing whatever to do; and that, while every candid man must admit that even a slave might be happy enough with a good master, all human beings knew that bad masters, cruel masters, and masters who disgraced the form they bore, were matters of experience and history, whose existence was as undisputed as that of slaves themselves. He was a little taken aback by this, and asked me if I believed in the Bible. Yes, I said, but if any man could prove to me that it sanctioned slavery, I would place no further credence in it. 'Well then,' he said, 'by God, sir, the niggers must be kept down, and the whites have put down the colored people wherever they have found them.' 'That's the whole question,' said I. 'Yes, and by God,' says he, 'the British had better not stand out on that point when Lord Ashburton comes over, for I never felt so warlike as I do now,—and that's a fact.' I was obliged to accept a public supper in this Richmond, and I saw plainly enough there that the hatred which these Southern States bear to us as a nation has been fanned up and revived again by this Creole business, and can scarcely be exaggerated.

. . . . "We were desperately tired at Richmond, as we went to a great many places and received a very great number of visitors. We appoint usually two hours in every day for this latter purpose, and have our room so full at that period that it is difficult to move or breathe. Before we left Richmond, a gentleman told me, when I really was so exhausted that I could hardly stand, that 'three people of great fashion' were much offended by having been told, when they called last evening, that I was tired and not visible, then, but would be 'at home' from twelve to two next day! Another gentleman (no doubt of great fashion also) sent a letter to me two hours after I had gone to bed, preparatory to rising at four next morning, with instructions to the slave who brought it to knock me up and wait for an answer!

"I am going to break my resolution of accepting no more public entertainments, in favor of the originators of the printed document overleaf. They live upon the confines of the Indian territory, some two thousand miles or more west of New York! Think of my dining there! And yet, please God, the festival will come off—I should say about the 12th or 15th of next month." . . .

The printed document was a series of resolutions, moved at a public meeting attended by all the principal citizens, judges, professors, and doctors of St. Louis, urgently inviting to that city of the Far West the distinguished writer then the guest of America, eulogizing his genius, and tendering to him their warmest hospitalities. He was at Baltimore when he closed his letter.

"Baltimore, Tuesday, March 22d.

"I have a great diffidence in running counter to any impression formed by a man of Maclise's genius, on a subject he has fully considered." (Referring, apparently, to some remark by myself on the picture of the Play-scene in Hamlet, exhibited this year.) "But I quite agree with you about the King in Hamlet. Talking of Hamlet, I constantly carry in my great-coat pocket the Shakspeare you bought for me in Liverpool. What an unspeakable source of delight that book is to me!

"Your Ontario letter I found here to-night: sent on by the vigilant and faithful Colden, who makes every thing having reference to us or our affairs a labor of the heartiest love. We devoured its contents, greedily. Good Heaven, my dear fellow, how I miss you! and how I count the time 'twixt this and coming home again! Shall I ever forget the day of our parting at Liverpool! when even —— became jolly and radiant in his sympathy with our separation! Never, never shall I forget that time. Ah! how seriously I thought then, and how seriously I have thought many, many times since, of the terrible folly of ever quarreling with a true friend, on good-for-nothing trifles! Every little hasty word that has ever passed between us rose up before me like a reproachful ghost. At this great distance, I seem to look back upon any miserable small interruption of our affectionate intercourse, though only for the instant it has never outlived, with a sort of pity for myself as if I were another creature.

"I have bought another accordion. The steward lent me one, on the passage out, and I regaled the ladies' cabin with my performances. You can't think with what feeling I play Home Sweet Home every night, or how pleasantly sad it makes us. . . . And so God bless you. . . . I leave space for a short postscript before sealing this, but it will probably contain nothing. The dear, dear children! what a happiness it is to know that they are in such hands!
