"Here," said Trendon, "I resign. From now on I'm a spectator."

Barnett swung the fulminate in his handkerchief and gave it to a sailor to hold. The man dandled it like a new-born infant. Back to his rock went Barnett. Producing some cord, he let down an end.

"Tie the handkerchief on, and get out of the way," he directed.

With painful slowness the man carried out the first part of the order; the latter half he obeyed with sprightly alacrity. Very slowly, very delicately, the expert drew in his dangerous burden. Once a current of air puffed it against the face of the rock, and the operator's head was hastily withdrawn. Nothing happened. Another minute and he had the tiny shell in hand. A fuse was fixed in it and it was shoved under the mud-cap. Barnett stood up.

"Will you kindly order the boat ready, Captain Parkinson?" he called.

The order was given.

"As soon as I light the fuse I will come down and we'll pull out fifty yards. Leave the rest of the Joveite where it is. All ready? Here goes."

He touched a match to the fuse. It caught. For a moment he watched it.

"Going all right," he reported, as he struck the water. "Plenty of time."

Some seventy yards out they rested on their oars. They waited. And waited. And waited.
