Claudius was silent, and he blew a great cloud of smoke.  What sort of a travelling companion would Mr. Barker be for him?  Could there be a greater contrast to his own nature?  And yet he felt that he would like to observe Mr. Barker.  He felt drawn to him without knowing why, and he had a presentiment that the American would drag him out of his quiet life into a very different existence.  Mr. Barker, on the other hand, possessed the showman’s instinct.  He had found a creature who, he was sure, had the elements of a tremendous lion about town; and having found him, he meant to capture him and exhibit him in society, and take to himself ever after the credit of having unearthed the handsome, rich, and talented Dr. Claudius from a garret in Heidelberg.  What a story that would be to tell next year, when Claudius, clothed and clipped, should be marrying the girl of the season, or tooling his coach down the Newport avenue, or doing any of the other fashionable and merry things that Americans love to do in spring and summer!

So Mr. Barker insisted on driving Claudius back to his lodging, though it was only five minutes’ walk, and exacted a promise that the Doctor should take him on the morrow to a real German breakfast at the Fauler Pelz, and that they would “start off somewhere” in the afternoon.

Claudius said he had enjoyed a very pleasant evening, and went up to his room, where he read an elaborate article on the vortex theory by Professor Helmholtz, with which, having dipped into transcendental geometry, he was inclined to find fault; and then he went calmly to bed.

CHAPTER III.

Claudius told his old landlord—­his philister, as he would have called him—­that he was going away on his customary foot tour for a month or so.  He packed a book and a few things in his knapsack and joined Mr. Barker.  To Claudius in his simplicity there was nothing incongruous in his travelling as a plain student in the company of the exquisitely-arrayed New Yorker, and the latter was far too much a man of the world to care what his companion wore.  He intended that the Doctor should be introduced to the affectionate skill of a London tailor before he was much older, and he registered a vow that the long yellow hair should be cut.  But these details were the result of his showman’s intuition; personally, he would as readily have travelled with Claudius had he affected the costume of a shoeblack.  He knew that the man was very rich, and he respected his eccentricity for the present.  To accomplish the transformation of exterior which he contemplated, from the professional and semi-cynic garb to the splendour of a swell of the period, Mr. Barker counted on some more potent influence than his own.  The only point on which his mind was made up was that Claudius must accompany him to America and create a great sensation.

“I wonder if we shall meet her,” remarked Mr. Barker reflectively, when they were seated in the train.
