"Now, I've simply got to hustle!" sighed Tom Reade nervously. "If I don't succeed in raising the wire, and in a mighty short s.p.a.ce of time, I may be to-night's fool yet. I'd really like to wish that on the black man, too!"

By using his eyes and his reasoning powers Reade, after twenty minutes more of search, with some sly digging, unearthed a section of the wire some dozen feet from the magneto.

"Now, it must be really the swiftest sort of work," murmured the young engineer, after a glance seaward. He seated himself with his face turned toward the Gulf, gathered the exposed section of wire up into his lap, then drew a pair of wire nippers from his pocket.

Snip! Tom now had two ends of wire in his hands. That would have been enough, had Reade chosen to bury the ends and conceal all evidence of his work. However, he believed that a more workmanlike way could be found.

From the same pocket Tom drew out a three inch piece of pure rubber cable, wrapped in water-proof tape. This he fastened to the severed ends of the wire, binding the whole as neatly as a lineman could have done.

"Rubber is believed to be a pretty good insulator," chuckled Reade, as he finished. "I don't believe the spark is made that can jump three inches of rubber. Certainly magneto-power can't do it. Now, let me see what sort of a trail-concealer I am."

Tom laid the wire back in the ground, covering it carefully with his hands.

"I wish I dared strike a match, so that I could judge better just how my work looks," he sighed. "However, I don't believe Mr. Sambo Ebony will think it discreet to strike any matches either, so he won't find the place where I've been fooling with his work.

"Now, I'll get back out of sight, where I belong," muttered Tom, rising cautiously. "I hope, though, I can find a place where I can see the look on that darkey's face when he tries his magneto and waits for the bing!

from out yonder. Oh, Sambo, you simply can't have any idea of how I've been wishing it on you tonight!"

As the bushes grew thickly hereabouts, and there were many hollows in the surface of the earth, Reade had little trouble in finding what he believed to be a satisfactory hiding place. It enabled him to hide his head within fifteen feet of the handle of the magneto.

A soft, southerly wind blew in from the Gulf. As long as he could Reade fought drowsiness. Again and again he opened his eyes with a start.

"I mustn't do this," Tom told himself angrily. "No gentleman will go to sleep at the switch---when it's his train that is coming!"

Yet still he found himself nodding. Had he deemed it safe Tom would have sprung up and walked about briskly. But this, he knew, was to invite being discovered by the returning negro.

So, at last, despite himself, Tom fell asleep.

How much time had pa.s.sed he never knew. At last, however, he awoke with a start. Reproachfully he rubbed his eyes.

"Not a bit too soon!" he muttered, as his ears caught sound of an approaching step, and his eyes showed him the hulking form of the ma.s.sive foe. "Here comes my black man!"

CHAPTER XIV

THE BLACK MAN'S TURN

Closer to the earth Tom tried to burrow. As to a plan, Tom Reade had none now, save to watch, and, if possible, to learn something that he did not already know.

Soft-footed, despite his great bulk, the negro approached with an air of little concern. Plainly, the wretch did not much fear discovery---still less interference.

Humming an old plantation melody the negro reached his concealed magneto, then stood up for a brief moment, staring seaward in the direction from which he had just come. His garments dripped water; his whole appearance was bedraggled, yet there was something utterly s.h.a.ggy, majestic, in this huge specimen of the human race.

"Ah done reckon dem gemmen gwine lose some mo' of deir wall to-night,"

chuckled the negro softly.

"Go as far as you like, Mr. Sambo Ebony!" grinned Tom Reade, under his breath. "I've wished something else on you this time."

Carelessly the negro bent over his magneto, seized the handle and gave a push.

Then he straightened up, listening. Only the soft sighing of the southern wind came to his ears.

"Yo' shuah done gotta use a mo' greasy elbow dan dat, chile," chuckled this imp of Satan aloud, though in a soft voice that seemed out of all proportion to his bulk.

Then he gave a half dozen indolent though steady strokes to the handle of the magneto.

"Whah am dat 'splosion?" he asked himself in wonderment. "Am mah eardrum done gone busted? Moke, yo' am plumb lazy this night!"

This time the huge negro pumped at the handle of the magneto until he was all but out of breath. Several dozen shoves he had administered before he halted, let go of the magneto and raised himself to his full, majestic height.

"Some black witch hab done gwine wish a big hoodoo on me!" grunted the negro suspiciously. "Dis am do fust time dat de magernetto gwine back on me like dis!"

In his bewilderment the one whom Tom had named Sambo glared around him.

His eyes gleamed with a phosph.o.r.escence like that which one sees on the water on a lowering night. What Reade did not know was that this black man possessed eyes that were a little keener in the dark than a bat's.

With a sudden "Woof!" Sambo went up in the air, moved sideways, and came down on the startled Tom Reade with the force of a pile driver.

"Wha' yo' doing heah?" demanded the negro, gripping Reade by the coat collar and dragging that hapless engineer to his feet.

Tom did not answer. To save his life he couldn't have answered just then, his breath utterly gone.

"Wha' yo' want heah, anyway?" insisted Sambo, giving the youth a vicious shake.

There was blood before the negro's eyes, or he would sooner have recognized his victim. But at last he did see.

"So, I'se gwine cotch Mistah Reade himself!" snorted Sambo. "An' Ah reckon I'se gwine foun' de differculty wid my magernetto at de same time! Huh?"

Again he shook Tom, with an ease and yet a force that further drove the breath from the young engineer's body.

"Why doan' yo' talk!" glared the negro, holding Tom out at arm's length with one hand.

Tom could only groan. Yet that method of communication carried its own explanation to the big black.

"Reckon yo' gwine talk w'en yo' get gale enough in yo' lungs," grinned the negro. "In dat case Ah gwine lay yo' down on de groun' to fin' yo' breff."

Sambo's idea of laying Tom down was to give him a violent twist that brought the lad flat on the ground at his captor's feet. Then the negro sat on his captive to make sure that the latter did not escape.

"Take yo' time---ah got plenty," grimaced the black man.

Slowly the beaten-out breath came back to Tom Reade. Sambo, watching, knew finally that his quarry was at last able to talk.

"Wha' yo' do to mah magernetto?" demanded Sambo.

"Guess," breathed Tom.
