"We found the secret opening still remained fast closed. We hammered at it, tried crowbars, and did everything to attract your attention. Green tells me you never heard a sound."
"We made as much row as we could, sir," said Atherton. "The walls must be practically soundproof."
"I should say they are not soundproof now," continued Mr Buckley. "On Sir Silas's advice we sent to Polkarnis Mine for some men accustomed to the use of explosives, and this gentleman—Mr Copperas, the electrical works' manager—kindly came over to give his technical assistance."
"Yes, it's a wonder we didn't do more harm," added Mr Copperas. "Since we heard no sounds from within we naturally concluded that the three of you were farther along the tunnel. However, all's well that ends well, and your two chums have been through an experience I never wish to meet with: standing within a few feet of five pounds of gun-cotton when it exploded."
"Now, Atherton, we must be making a move," declared the Scoutmaster. "It will soon be dark, and you've had a couple of very trying days."
"How about the silver bowl, sir?" said the Scout, who had already noticed the signs of preparations of bricking up the gap. "I'll get it if you like."
"Don't worry about that, Atherton," interposed Sir Silas. "Get a good night's rest. You can have a bed here if you wish."
"No, thank you, sir," replied Atherton. "I think I shall sleep pretty soundly in camp."
"As you like," said the baronet. "I'll see that the bowl is brought out. Mr Copperas and I have a wish to have a look at this remarkable tunnel before it is actually sealed."
"Any further news of Tassh, sir?" asked Atherton, as, accompanied by the five "Otters," the Scoutmaster started at a brisk walk towards Polkerwyck.
