“Where’s Rockett?” his rescuer shouted in his ear. It was only then that he recognized Carroll, but Lang was too exhausted to do more than shake his head feebly.

CHAPTER V
THE DIGGER

Late the next afternoon they were taken into Gulfport on board a Grand Cayman schooner laden with Jamaica timber.

What had become of Rockett, or of any of the rest of the Cavite’s crew they had not the slightest idea. From the upturned boat the sea was a blur of fog. They must have been drifting with some current, for the far-away steamer seemed continually to grow more distant. Expecting her boats, they shouted with what faint voice they could muster; but nothing came of it. If she had sent boats they were invisible; and after nearly an hour they heard the starting of the steamer’s engines, and her pale glow melted into distance.

Tropical though the latitude was, it seemed bitterly cold that night. Lang wore only a coat and trousers over his sleeping suit, and he felt numbed and stiff to the bone. He might have perished, but Carroll, who was fully dressed, had a pocket flask of rum, and pulled him periodically back to life with fiery sips. The bottom of the boat was a most awkward refuge, for they were in constant danger of slipping off; and once Lang, faint and dozing, did go into the sea, to be hauled out again by his companion.

That night seemed longer to Lang than all the rest of his life. The shore seemed a remote impossibility, but he did not know that much-frequented part of the Gulf. When the sun rose there were no less than three ships in sight, all miles away, indeed, but the sight of them was enough to put heart into him, together with the warming effect of the strong sunshine. Carroll, who had expected rescue, was not surprised; and seemed only impatient at the delay before the Grand Cayman schooner came alongside, and her crew with the kindliest solicitude took them aboard, and appropriated the Cavite’s boat as salvage.

During that endless, freezing, hopeless night the two castaways had scarcely exchanged a dozen phrases, yet Lang’s mind had continually reverted in a numb way to Rockett’s last incomprehensible words. “Twelve o’clock—nine and six—the negro digger——” There was no sense in it, and yet the defaulter had evidently been trying to convey some meaning. His house—to the north of Persia—what could that have to do with Automotive Fuel? No meaning could be tortured out of it, and yet Lang’s dazed mind circled round and round the insoluble problem.

But on the schooner, warmed and fed and smoking a Jamaica cigar, he conceived more hope. Rockett had said he trusted him—Heaven knew why! He had said to go “to his house,” and Lang determined to go, if he could find out where that house was. Yes, and he would be there at noon, at nine and at six, and see what these mystic hours might bring.

He turned this over in his mind while, with his surface faculties, he idly discussed with Carroll the probable fate of their shipmates. They had no idea whether the motor boat had been successfully launched, or whether any one had escaped in it. As for Rockett, his fate was hardly even doubtful. Unless picked up at once he could never have survived the plunge and exposure.

“He did speak, you know,” said Carroll suddenly. “I heard him say something to you. What was it?”
