Lieutenant Jack therefore gave the rising sign.
"I want to show the midshipmen everything possible on this trip," said the very young commanding officer.

"So we won't lie here in the mud any more.

Mr.Somers, you will return to the tower steering wheel, and you, Mr.Hastings, will take direct charge of the engines.

I will gather the midshipmen around me here in the cabin, and show the young gentlemen how easily we control the rising of a submarine from the bottom." Hal and Eph hurried to their stations.

The midshipmen followed Jack Benson over to what looked very much like a switchboard.
The young lieutenant held a wrench in his right hand.
"I will now turn on the compressed air device," announced Lieutenant Jack.
