Farther down the mountain, Rollo directed her attention to a white building, which was seen very distinctly in the rays of the setting sun. This building, he said, must be the Hermitage.

"How do you know it is the Hermitage?" asked Rosie.

VIEW THROUGH THE GLASS.

"I know by the situation of it," said Rollo. "Look through the glass and you will see that it is the highest house on the mountain side. Besides, it stands on the end of a ridge or spur, projecting from the mountain, just as I know the Hermitage does, with a deep valley on each side of it."

"I should have thought that they would have built it in one of the valleys," said Rosie. "It would have been more sheltered then from the wind."

"No," said Rollo. "That would not have been a good plan at all, for then it would have been in the track of the streams of lava. The lava comes down through the valleys."

"I can see the zigzag road leading up to the Hermitage," said Rosie.

"Yes," replied Rollo; "and I think it probable we could see people going up or coming down, if there were any there now."
