So Rollo led the way, and Rosie followed out of the parlor into the hall, and from the hall along a sort of corridor which led to a narrow and winding stone stair.

"No," said Rosie, as soon as she began to ascend the stair, "I don't think mother will like to come. She does not like to go up long stairs, especially stone stairs, and more especially still, stairs that wind round and round."

"Wait and see," said Rollo.

After going round and round several times,—all the while ascending,—Rollo came out to a sort of open passage way, paved with glazed tiles of a very pretty pattern, where there was a door leading out to a balcony. From this balcony there was a narrow iron stair which led up on the outside of the house to the roof. Rollo led the way up this stair, and Rosie followed him, though somewhat timidly. They landed at length on a sort of platform among the chimneys, from which another stair led up to another platform, higher still, where Josie was.

"There!" said Rollo, as soon as he reached the first platform, "don't you think your mother would like to be here?"

Rosie looked around, and saw that a magnificent panorama presented itself to her view.

"She would like to be here very much, if she only dared to come," said Rosie.

On looking towards the east, Rosie could survey the whole shore of the bay in that direction, with the continuous line of towns and villages along the margin of the water, and the immense green slopes of Vesuvius rising beyond. Among the green fields and groves, far up these slopes, white hamlets and villas were scattered, and above, the double summit of Vesuvius was seen, with dense volumes of white smoke ascending from one of the peaks. The children, too, could look from where they stood far out over the bay, and see the ships and steamers in the offing, and great numbers of small boats plying to and fro nearer the shore.

Rollo had an opera glass in his hand, which he used as a spy-glass. He let Rosie look through this glass at the mountain, so that she might see the smoke coming out more distinctly. With the glass, besides the general column of vapor, she could discern several places, near the summit, where small, separate puffs of smoke were issuing.
