Their Vienna sojourn had been one of the most brilliant periods of their life, as well as one of the saddest. The memory of Susy had been never absent, and the failing health of Jean was a gathering cloud.

They stopped a day or two at Prague, where they were invited by the Prince of Thurn and Taxis to visit his castle. It gave them a glimpse of the country life of the Bohemian nobility which was most interesting. The Prince's children were entirely familiar with Tom Sawyer and Huckleberry Finn, which they had read both in English and in the translation.

They journeyed to London by way of Cologne, arriving by the end of May. Poultney Bigelow was there, and had recently been treated with great benefit by osteopathy (then known as the Swedish movements), as practised by Heinrick Kellgren at Sanna, Sweden. Clemens was all interest concerning Kellgren's method and eager to try it for his daughter's malady. He believed she could be benefited, and they made preparation to spend some months at least in Sanna. They remained several weeks in London, where they were welcomed with hospitality extraordinary. They had hardly arrived when they were invited by Lord Salisbury to Hatfield House, and by James Bryce to Portland Place, and by Canon Wilberforce to Dean's Yard. A rather amusing incident happened at one of the luncheon-parties. Canon Wilberforce was there and left rather early. When Clemens was ready to go there was just one hat remaining. It was not his, and he suspected, by the initials on the inside, that it belonged to Canon Wilberforce. However, it fitted him exactly and he wore it away. That evening he wrote:

PRINCE OF WALES HOTEL, DE VERE GARDENS,
July,3, 1899.

DEAR CANON WILBERFORCE,—It is 8 P.M. During the past four hours I have not been able to take anything that did not belong to me; during all that time I have not been able to stretch a fact beyond the frontiers of truth try as I might, & meantime, not only my morals have moved the astonishment of all who have come in contact with me, but my manners have gained more compliments than they have been accustomed to. This mystery is causing my family much alarm. It is difficult to account for it. I find I haven't my own hat. Have you developed any novelties of conduct since you left Mr. Murray's, & have they been of a character to move the concern of your friends? I think it must be this that has put me under this happy charm; but, oh dear! I tremble for the other man!

Sincerely yours,
S. L. CLEMENS.

Scarcely was this note on its way to Wilberforce when the following one arrived, having crossed it in transit:

July 3, 1899.

DEAR MR. CLEMENS,—I have been conscious of a vivacity and facility of
expression this afternoon beyond the normal and I have just discovered
the reason!! I have seen the historic signature “Mark Twain” in my hat!!
Doubtless you have been suffering from a corresponding dullness & have
wondered why. I departed precipitately, the hat stood on my umbrella and
was a new Lincoln & Bennett—it fitted me exactly and I did not discover
the mistake till I got in this afternoon. Please forgive me. If you
should be passing this way to-morrow will you look in and change hats?
or shall I send it to the hotel?
I am, very sincerely yrs.,
20 Dean's Yard. BASIL WILBERFORCE.

Clemens was demanded by all the bohemian clubs, the White Friars, the Vagabonds, the Savage, the Beefsteak, and the Authors. He spoke to them, and those “Mark Twain Evenings” have become historic occasions in each of the several institutions that gave him welcome. At the Vagabonds he told them the watermelon story, and at the White Friars he reviewed the old days when he had been elected to that society; “days,” he said, “when all Londoners were talking about nothing else than that they had discovered Livingstone, and that the lost Sir Roger Tichborne had been found and they were trying him for it.”
