"Well," said Mr. Titus, after a pause. "The men are either in the tunnel or out of it. If they're in we don't dare set off the blast, and if they're out they'll show up, sooner or later, for supper. I never knew any of 'em to miss a meal."

"If such a thing were possible," said Walter Titus, "I would say that our rivals had a hand in this, and had induced our men to bolt in order to cripple our force. But we haven't seen any of Blakeson & Grinder's emissaries about, and, if they were, how could they get the ten men out of the tunnel without our seeing them? It's impossible!"

"Well, what did happen then?" asked Tom.

"I'm inclined to think that the men came out and neither you, nor any one else, saw them. They ran away for reasons of their own. We'll take another look in the morning, and then set off the blast."

And this was done. There being no trace of the men in the tunnel it was deemed safe to explode the charges. This was done, a great amount of rock being loosened.

The laborers hung back when the orders were given to go in and clean up. There were mutterings among them.

"What's the matter?" asked Job Titus.

"Them afraid," answered Serato. "Them say devil in tunnel eat um up! No go in."

"They won't go in, eh?" cried Tim Sullivan. "Well, they will thot! If there's a divil inside there's a worse one outside, an' thot's me! Git in there now, ye black-livered spalapeens!" and catching up a big club the Irishman made a rush for the hesitating laborers. With a howl they rushed into the tunnel, and were soon loading rock into the dump cars.
