"There!" said Rollo to Jennie, pointing down; "there's the place where we stood when we looked up to this whispering gallery at the time we first came in." The party went on until they had walked half round the gallery and were exactly opposite the man who was standing at the door where they had entered. Here Mr. George stopped and sat down upon the seat. [Illustration: THE WHISPERING GALLERY.] "Come," said he, "we must all sit down on this seat and put our ears against the wall." Mrs. Holiday and the children did as Mr. George had directed, and listened. The man at the door, then putting his mouth to the wall, began to speak in a low tone,--almost in a whisper, in fact,--saying something about the building of the church; and though he was at a great distance from them,--so far, that if he had been in the open air it would have been necessary for him to have called out in a very loud voice to make them hear,--yet every word and syllable of his whisper was distinctly audible, the sound being brought round in some mysterious manner along the smooth surface of the wall. "It is very extraordinary!" said Mrs. Holiday. "It is, indeed!" said Mr. George. Rollo himself, however, did not seem to be so much interested in this acoustic phenomenon as his uncle had been. His attention was attracted to the spectacle of the workmen, who were employed in repainting the inner surface of the dome, and whom he could now see at their work on the staging which he had looked up to from below. One side of the staging--the side towards the wall--was supported by a cornice, which it rested upon there. The other side--the side that was towards the centre of the dome--was suspended by ropes and pulleys, which came down through the lantern from a vast height above. There was a ladder, the foot of which rested on this staging, the top of it being placed against the surface of the dome above. There was a man upon this ladder, near the top of it, at work on the ceiling, and two or three assistants on the staging at the foot of it. Rollo and Jennie gazed some time with great wonder and awe at this spectacle, picturing to their imaginations the scene which would ensue if the ropes from the lantern above, by which the staging was suspended, were to break and let the staging, the ladders, and the men all down to the pavement below.
