Down at the mole a British sentry stopped the trio. Near him stood a corporal and three other soldiers.

"American officers and a friend," replied Ensign Darrin, when halted by this sentry. Then the trio advanced when ordered. Lieutenant Totten, from the 'Hudson,' stepped forward, peered at Darrin and Dalzell, and said to the corporal:

"I recognize these gentlemen as officers of ours."

"And the friend?" inquired the corporal.

"The friend is an American citizen who has business with Admiral Timworth," Dave stated.

"Then it is all right," Lieutenant Totten assured the corporal.

Whereupon the British corporal permitted Cushing to step out on the mole with his companions, Darrin and Dalzell.

"Which is the flagship launch?" asked Darrin.

"The rearmost," answered Lieutenant Totten. "Ours is the only launch here. The two other launches belong to the warships of other powers."

Cushing, while this brief conversation was going on, had walked rapidly along the mole until he reached the farthest launch.
