"They've been using the wireless," he stated evenly, "to run us in a cul de sac. I might have known German cruisers were close around." He looked steadily at the distant fighting tops, then turned to Galton.

"Steer due north, quartermaster."

After a moment, he said to Malone:

"When you go below, send me up coffee and a biscuit."

CHAPTER XX

THE LONE CHANCE

Rushing up the slope of the world in a battle line that covered a wide sector of the southwestern horizon, steamed four German battle cruisers. They were four sea eagles dashing at a little water beetle of a tug—the hammer of Thor swinging forward to crush an insect. The submarine had signaled by wireless the whole German South Atlantic fleet to destroy the tug.

Only in the face of this demonstration did Madden realize that a great German naval stratagem hinged upon the fate of the little English boat. The slow, clumsy little Vulcan would decide the fate of millions of dollars worth of English shipping. The little vessel was freighted with huge consequences.

At first glimpse of the battle line, the Vulcan had sheered about, and now rushed northward, stringing her black smoke flat behind her. Up from the south, the submarine followed on the surface, although she could not make as good time through the weed as did the Vulcan. However, the burden of destroying the English craft had been transferred to the cruisers that came rushing forward at at least twenty-five knots an hour.
