Then he rose wildly, and raged about the place, flinging his arms on
high, so that even Burnley, though his own reason was shaken, cowered
away from the fury of a stronger mind.

"Men and angels cry out against it!" he screamed, in madness and despair.
"Can this thing be? Can Heaven and earth look calmly on and see this
horror? Are men all ingratitude? IS GOD ALL APATHY?"

A blow like a hammer striking a church bell tinkled outside the wall, and
seemed to come from a great distance.

To him who, like the rugged Elijah, had expostulated so boldly with his
Maker, and his Maker, who is not to be irritated, forgave him, that blow
seemed at first to ring from heaven. He stood still, and trembled like a
leaf; he listened; the sound was not repeated.

"Ah," said he, "it was an illusion like hers."

But for all that he seized his hammer, and darted to the back of the
hall, and mounting on a huge fragment of coal struck the seam high above
his head. He gave two blows at longish intervals, and then three blows in
quick succession.

Grace heard, and began to raise herself on her hands in wonder.

Outside the wall came two leisurely blows that seemed a mile off, though
they were not ten feet, and then three blows in quick succession.

"My signal echoed," yelled Hope. "Do you hear, child, my signal answered?
Thank God! thank God! thank God!"

He fell on his knees and cried like a child. The next minute, burning
with hope and joy, he was by Grace's side, with his arms round her.

"You can't give way now. Fight on a few minutes more. Death, I defy you;
I am a father; I tear my child from your clutches." With this he raised
her in his arms with surprising vigor. It was Grace's turn to shake off
all weakness, under the great excitement of the brain.

"Yes, I'll live," she cried, "I'll live for you. Oh, the gallant men!
Hear, hear the pickaxes at work; an army is coming to our rescue, father;
the God you doubted sends them, and some hero leads them."

The words had scarcely left her lips when Hope set her down in fresh
alarm. An enemy's pickaxe was at work to destroy them; Burnley was
picking furiously at the weak part of the tank, shrieking, "They will
tear me to pieces; there is no hope in this world nor the next for me."

"Madman," cried Hope--"he'll let the water in before they can save us."
He rushed at Burnley and seized him; but his frenzy was gone, and
Burnley's was upon
