The Burning Bridge - Philip Verrill Mighels (best books for 8th graders TXT) 📗

Grenville cleaned his flint and steel. For an hour, then, he strove in vain to ignite his bit of tinder. It was not at all an easy matter to strike a spark from the stone. What few brilliant specks of incandescence sped occasionally downward like vigor transmuted into swiftly fading stars from Grenville's varied and over-eager strokes, either died on the air or missed their mark or struck it and found it uncongenial.

"This must be a vegetable asbestos," he finally declared. "If I had just a pinch of powder, this flint might recognize—— By Jove!" and he started at once to his feet. "I'm the greatest fool on legs!"

"What seems to be the trouble?" said Elaine, who could not possibly comprehend his meaning. "Have you made some sort of mistake?"

"I've been asleep—my brain defunct! Excuse me half a minute!"

He started madly down the trail, running like a boy. Before Elaine could do more than stare in wonder at his antics, he had reached the bottom of the wall, darted across the clearing, and disappeared in the jungle growth beyond.

He smashed his way hotly to the wrecked old barque, and, pawing deeply beneath the surface of the wasting saltpeter, that had been for long somewhat protected in the hold, promptly filled two pockets with the mineral, and went racing back as he had come.

But beyond the clearing he altered his course to enter the region once blackened by fire. Here he went directly to the hollow tree he had once before examined, and, wriggling inside, through the ample orifice burned out by the flames, he attacked the charred interior with his knife as if his very life depended on his haste.

In the briefest time he had chipped off more than a double handful of crisp, but inferior, charcoal. Retreating no less promptly than he had entered, he gathered this carefully in a giant leaf, and hastily rejoined Elaine.

"Powder!" he said, belatedly explaining. "Everything lying here and ready, and my brain a howling blank!"

To Elaine this was not precisely clear.

"There is gunpowder here on the island?"

"No! The ingredients merely. But any child—— Ah! here's my bit of sulphur! There's a ton of it ready to be gathered. Powder? I can make enough to blow a dozen tigers into ribbons! The wreck is full of niter and, once we have a fire, I can burn all the jungle into charcoal!"

The mystery had not entirely lifted for Elaine, but this she hardly expected.

"How can I help?" she asked him, quietly. "There must be something I can do."

"It's a matter of grinding these materials," he answered, more calmly, depositing sulphur, saltpeter, and charcoal on a rock before them. "It's a simple composition, after all."

Barely less feverishly than before he began a search for suitable stones to employ as mortars and pestles. There were many small bowlders slightly hollowed by the elements, but a number of these had surfaces ready to crumble, and were, therefore, reluctantly discarded. In throwing about some loosely huddled fragments, to liberate a smooth, hard slab of stone that was dished from its edges to its center, Grenville was doubly rewarded by coming upon a large, thick seashell, practically perfect.

With this and the basin of harder rock, he returned at once to the shade. He was soon reducing the charcoal, while Elaine no less industriously attacked the lump of sulphur.

"We need a little only for a trial," he said, as he presently sifted out his powdered product, and began to grind the niter. "I wish I remembered the proportions."

In his haste to obtain results as soon as possible, he finally shook up and ground together a large-sized pinch from each of the three materials, producing thereby a grayish, unpromising mixture, decidedly too rich in both the charcoal and sulphur.

This he placed on a rock, a safe distance away, and attacked with his flint and steel. Elaine had ceased her grinding operations, to stand at his side and watch. He struck, perhaps, a dozen times before he produced a shower of sparks—and nothing occurred. He looked at the stuff for a moment, helplessly, discouragement swiftly lodging in his bosom. Half-heartedly he struck the steel again.

A single spark flew hotly from the flint. It seemed to curve to the outside edge of the powder. Instantly, however, the mixture was ignited.

It did not burn in a quick, fierce flash, but more with a sputtering, imperfect combustion, productive of stifling fumes. Grenville's hand was slightly scorched—but his joy in the triumph was complete.

"We're kings!" he cried, sublimely indifferent to genders. "We're monarchs of all we survey!" He leaped up, waving his flint about his head, his face outbeaming the sun.

Elaine was vaguely glad of his results.

"I'm afraid I don't understand it in the least."

"Not at all necessary," he informed her, candidly. "It's the very worst powder ever made. My charcoal is poor and my proportions wrong, and I only half ground it all together. But it burned! That's enough for me—it burned! It assures us a fire, and I'll make a new batch, that will go off like a Spanish revolution!"

He went below at once to gather twigs and fuel, bits of dried grass, and other kindling, and brought a large bundle to the terrace. More carefully, then, he mixed and ground his succeeding sample of the powder. Recalling more clearly the accepted formula, he increased the proportion of saltpeter to something nearer seventy-five per cent. of the whole, approximating thus the standard long since established.

Aware that, when he finally came to manufacture an explosive of higher efficiency, he would do much better to wet the ingredients and later dry the finished product, he now proceeded, as before, merely to try for a fire.

Thus he presently laid a train of his grayish mixture from one small heap to another, in a place selected for his trial. Over one of the powder pyramids he arranged his combustible straws, twigs, and branches with the nicest care. And when, at length, he struck a white-hot star, divinely potential, into the midst of the second heap, a hissing snake of incandescence and smoke darted swiftly along the surface of rock—and his fire leaped into being.

On the towering rock, as on an altar, the flames that meant life to the exiled pair rose goldenly bright and clear.

A strange exultation in Grenville's prowess possessed Elaine, as she stood by in wonder, looking on his face.

"It shall never go out," he told her, presently, "not if I can prevent it."

CHAPTER X THE MASTER POACHER

There were woods in abundance about the base of the tufa cliff that would burn almost as slowly and retain their glow about as long as the hardest of anthracite coal.

Yet it was not on these that Grenville depended, that particular night, to maintain the fire he had conjured from flint and steel. All those long dark hours he served his altar flame with fuel gathered for the purpose. An easier method for its preservation, by means of the woods that were promptly discovered, he adopted, however, very soon.

Each day that was ushered in and closed by the island's haunting wails and chorus, now beheld some new development in the plans that Grenville was laying. Elaine, less disturbed by the hideous sounds, might have learned more promptly to accept them as part of the ordeal of living in this extraordinary fashion, had they always come at stated hours. But, born of the tides, they came with the tides, which, all the world over, shift with each day till every hour of the twenty-four has had its visitation. Like a horrid reminder of the brevity of life, the thing was fore-ordered to rise unexpectedly, fret forgetful senses, and linger longest, apparently, in the deadest hours of the night. Concerning her companion, her mind was far more calm. Her distrust and dislike were unabated, but he gave her no cause for added worry.

By the third day after his fire had been accomplished, Grenville had considerably altered their aspects and prospects of living. Their bamboo flagpole stood in a crevice of the highest rock, with "rags" of banana leaves idly flapping out a signal of distress; a number of pipkins, large and small, were grayly drying in the sun, to be subsequently fired; his bow was strung, beside three unfeathered arrows, crudely tipped with points that Sidney had pounded out of screws; charcoal was burning, down in the blackened clearing; a number of traps and dead-falls were nearing completion; and several basket loads both of sulphur and saltpeter were stored in caverns, which the man had roofed to protect them from the rain.

Much toil had been involved in these achievements. The bamboo pole, for instance, had been most laboriously burned off, close to its base. To accomplish this end, the man had carried coals of fire to the estuary swamp, created a blaze, and repeatedly heated his longest piece of brass, which had slowly charred a channel through the wood when smartly applied to its surface.

The cord that secured the "flag" upon this serviceable mast, had been made, like the string for the bow, by twisting together innumerable threads of the fiber imbedded in the bark of the creepers. This had then been "waxed" with the glutinous ooze from the nearest rubber tree, with which the jungle abounded. He had also found wild sisal in the rocky places of the island. This plant had a leaf like a bayonet, sometimes six feet long, and readily split into fibers of most astonishing strength, especially when three were braided into a cord.

Considerably to Grenville's amazement, the molding of jugs, some crucibles, and other essential vessels suggested by the presence of the clay, was not at all a simple matter. His material, which at first was mixed too soft, was readily stiffened to a workable consistency, and the bases and first six inches or more of flaring walls of his pipkins had been fashioned as a child would fashion "pies." It was when he undertook to crimp and contract this flaring rim that the craftsmanship known to the potter required once again to be evolved.

For a time the longer he wrought at the stubborn material the more completely Grenville was defeated by the clay. He discovered at last, as similar workmen in every age and clime have ultimately discovered, that potteries thus constructed by hand must be built up in rings, one ring at a time, especially where the walls draw in to an ever narrowing diameter.

When, at length, this simple fact had been established—the first success having come to Elaine, whose feminine wit had been nimbler far than the man's—a highly respectable family of jugs and useful receptacles had rapidly come into being.

Mid-afternoon of this busy day found Grenville engrossed with his labors. Despite the fact they had not yet dined on anything but fruit, he was preparing salt for meat. The shell he had found was full of water from the sea, evaporating rapidly in a bed of hot ashes and coals. This, however, was resigned to Elaine's efficient vigilance, while Sidney worked absorbingly to complete a number of small clay molds designed for the casting of tools.

When, at length, the last of these was done and set aside to dry with the jugs and assorted vessels, he glanced briefly up at the sun. There were several hours of this blazing light remaining. Resolved in one moment to hasten to the jungle with his bow and the unfeathered arrows, which might be relied upon at easy range to fly sufficiently straight for all his purposes, Grenville determined in the next to make them a bit more certain.

A branch and leaf from a freshly despoiled banana plant had suggested "feathers" for his shafts. It was the work of a moment only to cut out and trim a slender bit of the fibrous branch from which the leaf substance projected. The leaf part itself, which was rather tough, and considerably like a stiffened cloth in texture, he cut to shape no less
