He led the way to the foot of the broken periscope, and quickly summoned several members of the crew. With all possible haste the second periscope, carried for just such an emergency, was brought out and run up.

“The only way we can tell whether it is adjusted properly,” said Lord Hastings, “is to rise, and that is exceedingly dangerous.”

“Well, we shall have to take a chance,” said Frank.

“So we shall,” was the reply. “You may give the order, Mr. Templeton.”

Jack did as commanded, and slowly the submarine began to rise. Lord Hastings stood at the foot of the second periscope, peering intently into it. At last he raised his hand in a sudden signal, and immediately the vessel began to sink again.

“It’s all right,” said the commander, turning to the lads. “I caught a glimpse of the surface.”

“Then we are all fixed again,” said Frank thankfully.

“Yes.”

“Then,” said Jack, “I should say the thing to do is to put as great distance as possible between us and the enemy.”

“The only draw back to that,” said Lord Hastings, “is that I do not know just where we are and to move in any direction is decidedly dangerous.”
