It was a very pleasant summer morning, and Rollo had a delightful sail in going over to the island. Mr. George and the landlord talked together nearly all the way; but Rollo did not listen much to their conversation, as he could not understand the landlord very well, notwithstanding that the language which he used was English. He was seated next to the girls; but he did not speak to them, as he felt sure that they did not know any language but German. So he amused himself with looking at the hills on the shore, and at the gardens and vineyards which adorned them, and in tracing out the zigzag paths which led up to the arbors and summer houses, and to the ancient ruins. He attempted at one time to look down into the water by the side of the boat, to see if he could see any fishes; but the water of the Rhine is very turbid, and he could not see down into it at all. At length the boat came to the land in a little cove on the side of the island, where there was a sandy beach, under the shade of some ancient trees. There was a path leading from this place up towards the convent. The party in the boat landed, and began to walk up this path. Mr. George and the landlord were first, and Rollo came next. [Illustration: THE NUN.] The little path that they were walking in came out into another which led along among the fields that extended down the island. There was a nun coming up this path, leading one of the schoolgirls. It seems they had been to take a walk. The nun had her face shaded by a large cap, or bonnet, with, a veil over it; and though she looked pale, her countenance had a very gentle expression, and was very beautiful. She bowed to the party that was coming up from the boat, and went on before them to the church. "I wonder whether she is happy," thought Rollo to himself, "in living on this island, a nun. I wish I knew where her father and mother live, and how she came to be here, such a beautiful young lady." This nun was indeed very beautiful, though she was an exception to the general rule, for nuns are often very plain. The church formed a part of the convent building. It was, in fact, only a small chapel, built in a wing of the convent, with a little cupola and a bell over it. The bell was ringing when the party from the boat went up towards the edifice. On entering Rollo found that the room was very small. At the upper end was a platform, with an altar and a crucifix at the farther end of it. The altar had very tall candles upon it, and several bouquets of flowers. The candles were lighted.
