They scrambled up the ladder and found themselves on the crowded bridge with two other men.

“I’m Lieutenant Commander Sutherland,” said the man who had greeted them, “Executive Officer.” He turned to the other officer on the deck. “Captain Binkey—Lieutenant Anson and Ensign Bigelow reporting.”

The Captain smiled as he returned their salute and then lapsed into his customary informal role.

“Glad to have you aboard,” he said. “First ride, eh?”

“Yes, sir,” March and Stan replied, feeling at ease at once in the old veteran’s presence.

“Sutherland will show you around after we get started,” the Skipper said. “I imagine you’ll want to stay up here till we’re under way.”

Sutherland turned to them. “You probably know from your studies what most of this is about,” he said. “Just a matter of seeing and feeling it to be at home. I know I don’t have to tell you every little detail the way the Chief down there is pointing out every steel plate to those ratings.”

March and Stan glanced down to see that the Chief had led his enlisted men on to the deck of the submarine, where they were mingling with the regular crew who were preparing to cast off when the Captain ordered.

“Whenever you want to know anything,” Sutherland went on, “just ask me and I’ll try to give you the answer. I imagine we’ll be casting off in a minute.”

They saw the Chief Petty Officer leading his students down the torpedo-room hatch to the interior of the submarine, and for a moment March wanted to join them.
