Rollo found the cost, too, of travelling in Switzerland much less than he had expected. He did not expend nearly all the allowance which his father had granted him. When he came to settle up his accounts, after he had got back to Paris, he found that he had saved about seventy-five francs, which made nearly fifteen dollars; and this sum he accordingly added to his _capital_--for that was the name by which he was accustomed to designate the stock of funds which he had gradually accumulated and reserved. Just before Mr. George and Rollo left Switzerland, on their return to Paris, they received a letter from Mr. Holiday, who was still in Paris, in consequence of which they concluded to make a short tour on the Rhine on their way to France. The adventures which they met with on this tour will form the subject of another volume of this series.
