It occurred to the Hawk that the asteroid was a developing shooting star, eating up the few hundred miles of life that remained, streaking down into the atmosphere, where waited quick friction and incandescence and he down in the heart of it, blind, without clue to what lay in front of him, ignorant of everything, and with only minutes in which to achieve his end.
There was a report, a sudden leap of flame, and the continued hissing fury of the short-circuited current, until the bar, heated to incandescence, twisted and writhed where it lay like a thing of life. He drew a deep breath, and watched it. That was the danger he had so closely skirted? That was the fate which he had escaped!
They are fine, these moments of conflagration, of mineral incandescence, when the sober limestone rocks take on the tints of molten copper, their convulsed strata standing out like the ribs of some agonized Prometheus, while the plain, where every little stone casts an inordinate shadow behind it, clothes itself in demure shades of pearl. Fine, and all too brief.
After verifying, varying, and expanding the results of Bancalari, he submitted to examination heated air-currents, produced by platinum spirals placed in the magnetic field, and raised to incandescence by electricity. He then examined the magnetic deportment of gases generally. Almost all of these gases are invisible; but he must, nevertheless, track them in their unseen courses.
In the darkness the discharge of the Zouaves' rifles ran from the guns' muzzles like streams of molten metal spilling out on the grass. McDunn's guns spirted great lumps of incandescence; the fuses of the shells in the sky showered the darkness with swarming sparks. Toward ten o'clock the harried column halted on a hill and bivouacked without fires, food, or shelter.
A many other little things may have gone as near. If so, none left any one of its audience, or witnesses, more absolutely in the dark about it than the solitary old woman who that evening watched that log, stimulated by the scrapwood during her very perfunctory supper; first till it became a roaring flame that laughed at those two candles, then till the flame died down and left it all aglow; then till the fire reached its heart and broke it, and it fell, and flickered up again and died, and slowly resolved itself into a hillock of red ember and creeping incandescence, a treasury still of memories of the woodlands and the coming of the spring, and the growth of the leaves that perished.
Edison also tried hard carbon, wood carbons, and almost every conceivable variety of paper carbon in like manner. With the best vacuum that he could then get by means of the ordinary air-pump, the carbons would last, at the most, only from ten to fifteen minutes in a state of incandescence. Such results were evidently not of commercial value. Edison then turned his attention in other directions.
Flashing across his range of vision at an incredible speed, a tiny thing, no more than twenty feet long and five in diameter, a scout-ship appeared. Its tiny nose ultra-violet beam was blasting a solid cylinder of violet incandescence a foot across in the hull of the Miran and, to the Miran, angling swiftly across his range of vision.
Thus though the one-thousandth of a degree may be all the fall of temperature that our earth now experiences in a twelvemonth, yet in those glowing days when the surface was heated to incandescence, the loss of heat per annum must have been immensely greater than it is now.
Converted into light only at the plate, it showed their progress as truly as though they had been traveling at a pace to be expressed in the ordinary terms of miles per hour. The yellow star that was the sun detached itself from the firmament and leaped toward them, swelling visibly, momentarily, into a blinding monster of incandescence.
