[Illustration: SHOPPING IN THE TUNNEL.]
Besides these things that were for sale, there were various objects of interest and curiosity, such as electric machines where people might take shocks, and scales where they might be weighed, and refreshment rooms that were formed in the passage way that was not used for travel; and in one place there was a little ball room arranged there, where a party might, if they chose, stop and have a dance.
Rollo and Mr. George walked through the Tunnel, and then came back again. As they came back, Rollo stopped at one of the shops and bought a pretty little round box, which he said would do for a wafer box, and would also serve as a souvenir of his visit to the place.
Mr. George and Rollo concluded, after ascending again to the light of day, that they would go home by water; so they went out to the end of a long floating pier, which was built, as it happened, exactly opposite the entrance to the Tunnel. They sat down on a bench by a little toll house there, to wait for a steamer going up the river.
"It must have been just about under here," said Rollo, "that I bought my little wafer box in the Tunnel."
"Yes," said Mr. George; "just about."
In a few minutes a steamer came along and took them in. She immediately set off again; and, after passing under all the London bridges and stopping on the way at various landings, she set them down at Hungerford stairs, and they went to their lodgings.

Mr. George and Rollo had various other adventures in London which there is not space to describe in this volume. Rollo did not, however, have time to visit all the places that he wished to see; for, before he had executed half the plans which he and his uncle George had projected, he received a sudden summons to set out, with his father, and mother, and Jennie, for Edinburgh.
