It was during the period of his convalescence that Clemens prepared his sixth letter for the New York Sun and McClure's syndicate, "The German Chicago," a finely descriptive article on Berlin, and German customs and institutions generally. Perhaps the best part of it is where he describes the grand and prolonged celebration which had been given in honor of Professor Virchow's seventieth birthday.—[Rudolph Virchow, an eminent German pathologist and anthropologist and scholar; then one of the most prominent figures of the German Reichstag. He died in 1902.] —He tells how the demonstrations had continued in one form or another day after day, and merged at last into the seventieth birthday of Professor Helmholtz—[Herman von Helmholtz, an eminent German physicist, one of the most distinguished scientists of the nineteenth century. He died in 1894.]—also how these great affairs finally culminated in a mighty 'commers', or beer-fest, given in their honor by a thousand German students. This letter has been published in Mark Twain's "Complete Works," and is well worth reading to-day. His place had been at the table of the two heroes of the occasion, Virchow and Helmholtz, a place where he could see and hear all that went on; and he was immensely impressed at the honor which Germany paid to her men of science. The climax came when Mommsen unexpectedly entered the room.—[Theodor Mommsen (1817-1903), an eminent German historian and archeologist, a powerful factor in all liberal movements. From 1874-1895 permanent secretary of the Berlin Royal Academy of Sciences.]

There seemed to be some signal whereby the students on the platform were made aware that a professor had arrived at the remote door of entrance, for you would see them suddenly rise to their feet, strike an erect military attitude, then draw their swords; the swords of all their brethren standing guard at the innumerable tables would flash from the scabbard and be held aloft—a handsome spectacle. Three clear bugle-notes would ring out, then all these swords would come down with a crash, twice repeated, on the tables and be uplifted and held aloft again; then in the distance you would see the gay uniforms and uplifted swords of a guard of honor clearing the way and conducting the guest down to his place. The songs were stirring, and the immense outpour from young life and young lungs, the crash of swords, and the thunder of the beer-mugs gradually worked a body up to what seemed the last possible summit of excitement. It surely seemed to me that I had reached that summit, that I had reached my limit, and that there was no higher lift devisable for me. When apparently the last eminent guest had long ago taken his place, again those three bugle-blasts rang out, and once more the swords leaped from their scabbards. Who might this late comer be? Nobody was interested to inquire. Still, indolent eyes were turned toward the distant entrance, and we saw the silken gleam and the lifted sword of a guard of honor plowing through the remote crowds. Then we saw that end of the house rising to its feet; saw it rise abreast the advancing guard all along like a wave. This supreme honor had been offered to no one before. There was an excited whisper at our table—"Mommsen!"—and the whole house rose —rose and shouted and stamped and clapped and banged the beer-mugs. Just simply a storm! Then the little man with his long hair and Emersonian face edged his way past us and took his seat. I could have touched him with my hand—Mommsen!—think of it!

This was one of those immense surprises that can happen only a few times in one's life. I was not dreaming of him; he was to me only a giant myth, a world-shadowing specter, not a reality. The surprise of it all can be only comparable to a man's suddenly coming upon Mont Blanc, with its awful form towering into the sky, when he didn't suspect he was in its neighborhood. I would have walked a great many miles to get a sight of him, and here he was, without trouble, or tramp, or cost of any kind. Here he was, clothed in a titanic deceptive modesty which made him look like other men. Here he was, carrying the Roman world and all the Caesars in his hospitable skull, and doing it as easily as that other luminous vault, the skull of the universe, carries the Milky Way and the constellations.

During his convalescent days, Clemens had plenty of time to reflect and to look out of the window. His notebook preserves some of his reflections. In one place he says:

The Emperor passes in a modest open carriage. Next that happy 12-year-old butcher-boy, all in white apron and turban, standing up & so proud!

How fast they drive-nothing like it but in London. And the horses seem to be of very fine breed, though I am not an expert in horses & do not speak with assurance. I can always tell which is the front end of a horse, but beyond that my art is not above the ordinary.

The "Court Gazette" of a German paper can be covered with a playing- card. In an English paper the movements of titled people take up about three times that room. In the papers of Republican France from six to sixteen times as much. There, if a Duke's dog should catch cold in the head they would stop the press to announce it and cry about it. In Germany they respect titles, in England they revere them, in France they adore them. That is, the French newspapers do.

Been taken for Mommsen twice. We have the same hair, but on examination it was found the brains were different.

On February 14th he records that Professor Helmholtz called, but unfortunately leaves no further memorandum of that visit. He was quite recovered by this time, but was still cautioned about going out in the severe weather. In the final entry he says:

Thirty days sick abed—full of interest—read the debates and get excited over them, though don't 'versteh'. By reading keep in a state of excited ignorance, like a blind man in a house afire; flounder around, immensely but unintelligently interested; don't know how I got in and can't find the way out, but I'm having a booming time all to myself.
