"Per hora!"
This means, By the hour.
At the same time Rollo held up his watch to the coachman, in order to let him see what o'clock it was.
"Si, signore," said the coachman.
Si, signore, is the Italian for Yes, sir.
Rollo could not say in Italian where he wished the coachman to go, and so he stood up in the carriage and pointed. Following his indications, the coachman drove in through the archway to the court of the post office, where he found Mr. George waiting. The trunk and the bags were put upon the carriage, in front, and Mr. George got in with Rollo.
"Hotel d'Amerique," said Mr. George to the coachman.
"Si, signore," said the coachman, and immediately he began to drive away.
The Hotel d'Amerique was the one where Mr. George had concluded to go. He had found the name and a description of this hotel in his guide book.
"Why did you want me to take the carriage by the hour?" asked Rollo.
