Hogan, who held the volume in the crook of his bandaged arm, licked his thumb and jabbed through the leaves in distracted attention. "There aren't no code letters for submarine!" he cried at last—"not in here!"
"No," shouted Black, the Vulcan's former captain, "that's an old code—wasn't any submarines then!"
"Spell it out!" commanded Caradoc from the bridge. "Sharp about it!"
The men worked in a clutter of buntings, assembling the flags in nervous haste. Black laid out the nine letters and the crew hurriedly hooked them together. Ten minutes later, they strung the signal between the two splintered masts with a queer drunken gala effect.
The Vulcan was no longer the German squadron's sole target. Down on the Teuton battle line thundered five English cruisers, filling the north with rolling smoke, their turrets spangled with cannon flashes, prows shearing white walls of foam.
The sky above the Vulcan was filled with the drone of hurtling shells. They sounded as thick as swarming bees. The cannon fire of the approaching English ships mounted to a ragged roar. When the on-coming line was less than five miles distant, Caradoc shouted an order to Galton and the little tug swung around broadside on, displaying her warning signal like a billboard. Through the battle smoke, Madden saw an answering flag go up on the nearest ship. A cheer broke out from the crew at this recognition of their work.
"They'll pass it around among the fleet by wireless!" shouted Caradoc in Madden's ear.
"Do you know that ship, Smith?" called Madden excitedly.
"The Panther—held a commission on her once."
"Is it possible?" Madden peered at her through his glasses with renewed scrutiny.
