As Jack, burning inwardly with indignation, though managing to keep outwardly calm, descended to the deck below, he caught sight of Hal Hastings, hovering near in the rowboat.  Hal signaled to learn whether he should put in alongside to take off his chum, but Benson shook his head.

Over on the “Farnum” the yard’s owner and Eph Somers watched wonderingly.  They understood, well enough, that the new, trim-looking gunboat was in trouble, but they did not know that Jack Benson was held at fault.

Down between decks the engines of the “Hudson” were toiling hard to run the craft off out of the sand.  Then the machinery stopped.  An engineer officer came up from below.  He and Mr. Mayhew walked to the stern, while a seaman, accompanying them, heaved the lead, reading the soundings.

“We’re stuck good and fast,” remarked the engineer officer.  “We can’t drive off out of that sand for the reason that the propellers are buried in the grit.  They’ll hardly turn at all, and, when they do, they only churn the sand without driving us off.”

“Confound that ignoramus of a boy!” muttered Mr. Mayhew, walking slowly forward.  It was no pleasant situation for the lieutenant commander.  Having run his vessel ashore, he knew himself likely to be facing a naval board of inquiry.

Hal, finding that the shore boat was not wanted for the present, had rowed over to the “Farnum’s” moorings.  Now Jacob Farnum came alongside in the shore boat.

“May I speak with your watch officer?” he called.

“I am the commanding officer,” Mr. Mayhew called down, in the cold, even, dulled voice of a man in trouble.

“I am Mr. Farnum, owner of the yard.  May I come on board?”

“Be glad to have you,” Lieutenant Commander Mayhew responded.

So Mr. Farnum went nimbly up over the side.

“May I ask what is the trouble here, sir?” asked the yard’s owner.

“The trouble is,” replied Mr. Mayhew, “that your enterprising boy pilot has run us aground—­hard, tight and fast!”

Jacob Farnum glanced swiftly at his young captain.  Jack shook his head briefly in dissent.  Jacob Farnum, with full confidence in his young man, at once understood that there was more yet to be learned.

“Come up on the bridge, sir, if you will,” requested the commander of the gunboat, who was a man of too good breeding to wish any dispute before the men of the crew.  “You may come, too, Benson.”

Jack followed the others, including the engineer officer of the “Hudson.”  Yet Benson was clenching his hands, fighting a desperate battle to get full command over himself.  It was hard—­worse than hard—­to be unjustly accused.

Jacob Farnum wished to keep on the pleasantest terms with these officers of the Navy.  At the same time he was man enough to feel determined that Jack, whether right or wrong, should have a full chance to defend himself.

“I understand, sir,” began Mr. Farnum, “that you attach some blame in this matter to young Benson?”
