"Mr. Reade, how are you going to protect the works to-night?" inquired the superintendent.

"I'm going to order Foreman Corbett and twenty men to night duty," Tom answered. "The motor boat will also be out to-night. We'll have every bit of the wall watched by men with lanterns."

"What you ought to do," suggested Treasurer Prenter, "is to light the breakwater up with electric lights. You have steam power enough here, and with a dynamo you could supply current to the lights."

"There's the expense to be considered," mildly observed President Bascomb.

"The expense is a good deal less than having the wall damaged by more explosions," said Prenter, rather sharply. "Reade, how long would it take you to get an electric light service going?"

"It ought not to take more than three or four days, sir, if we can pick up a suitable dynamo in Mobile. But there's another point to be considered. We very likely would have to obtain the permission of the Washington authorities before we could run a line of lights out into the Gulf of Mexico. You see, sir, so many uncharted lights might confuse the navigators of passing ships."

"Write Washington, then, and find out where you stand in the matter," directed the treasurer.

"Yes, sir; I'll do that," Reade agreed.

"But don't order any electrical supplies until you've got an estimate of the cost and have it approved by me," hinted President Bascomb. This cautious direction made Mr. Prenter shrug his shoulders.

Dinner finished, all hands went out to sit on the porch. Mr. Bascomb soon began to ask questions about the camp, the housing of the men, and about other details of the camp.
