"Will you pledge yourself never to see her again after this week?" demanded Sir William.

"I will not—certainly not," replied Shuffles. "I do not purpose to interfere in any way with your relations to her. If she desires to see me, and it is possible for me to see her, I shall not deny myself that pleasure."

The baronet suddenly turned upon his heel, and walked rapidly towards the hotel. Shuffles was amazed. He could not conceal from himself the truth that he was deeply interested in Lady Feodora, though no thought of anything beyond friendship occurred to either of them. They might or might not continue in company for another week, and then part, in all human probability, forever in this world. Still, the situation was novel enough to be exciting, and he lay awake, thinking of it, for several hours that night. But in the morning Sir William appeared as usual, and probably, on reflection, had decided not to do any desperate deed.

At seven o'clock the excursionists returned by train to Frankfurt. It was decided then that, as Wiesbaden, one of the celebrated German watering-places, was only a repetition of Baden-Baden and Homburg, the company should proceed direct to Mayence, where they arrived by nine o'clock.

CHAPTER XVIII.

CASTLES, VINEYARDS, AND MOUNTAINS.

As the students were crossing the bridge to Mayence, they obtained a full view of one of the great rafts of timber which float down the Rhine, and of which Professor Mapps had spoken to them at Dort, in Holland. However, it was much smaller than those of which they had heard, and they hoped to see another. The students were not disposed to "do" Mayence, being too impatient to witness the glories of the Rhine. But most of them, from a sense of duty rather than from an interest in the place, visited the principal attractions of the city.

"Mayence is the French name of the town," said the professor of geography and history, as the students collected in the railroad station, previous to the tramp. "The German name is Mainz, which is pronounced Mynts—y like long i. If you pronounce it in any other way, a German will not know what you mean. It was an old Roman town. A fortress was established here to keep back the barbarians. It was formerly a larger and more important city than at present, having now a population of only forty thousand.

"This place has done two grand things for civilization and for Europe. It was the cradle of the art of printing, and furnished the man who suppressed the robber knights. As you go down the Rhine, you will see the ruins of many old castles on the hills by the banks of the river. The nobles, who occupied them as strongholds, carried on a system of robbery, levying duties upon all who travelled on its waters or passed through their territory. Arnold von Walpoden suggested the plan which led to a confederation of the cities for the driving out of the knightly highwaymen, and the destruction of their strongholds. They were feudal lords, and the breaking of their power opened the way for the progress of civilization.
