"What is coming now?" speculated Frank. "The Danites seem dazed."

"Look, and you shall see what is coming," said Old Solitary, his fingers again closing on our hero's arm. "You can see Clyde's companion, the treacherous Graves. Watch; ah! I knew it!"

Graves was seen to rise behind Clyde, uplift some weapon in his hand, and strike the boy prostrate.

Then, with a yell that faintly reached the ears of the watching three, the Danites scrambled over the rocks.

"The tragedy is over," said Old Solitary, solemnly. "The deadly work is done. Poor boy!"

"Poor boy!" echoed Frank.

"It's dearly th' spalpanes will pay fer this noight!" grated Barney Mulloy. "It's nivver a bit will Oi hesitate about stoppin' wan av th' divvils from b'rathin' av Oi get a chance."

"I do not think my conscience will trouble me much if I am forced to finish one of them," said Frank, huskily.

"They are beasts—human beasts!" declared Old Solitary. "It is not a sin to place such where they can do no harm to the rest of the world."
