Part 18 (2/2)

A thin, almost imperceptible column of blue smoke was rising among the trees some twenty yards away at the foot of the mound. It curled up and up, and disappeared from sight among the tangled branches overhead. It was scarcely thicker than the smoke from a small brand of burning wood.

”Protect yourself! Imagine your sh.e.l.l strongly,” whispered the doctor sharply, ”and follow me closely.”

He rose at once and moved swiftly down the slope towards the smoke, and I followed, afraid to remain alone. I heard the soft crunching of our steps on the pine needles. Over his shoulder I watched the thin blue spiral, without once taking my eyes off it. I hardly know how to describe the peculiar sense of vague horror inspired in me by the sight of that streak of smoke pencilling its way upwards among the dark trees.

And the sensation of increasing heat as we approached was phenomenal. It was like walking towards a glowing yet invisible fire.

As we drew nearer his pace slackened. Then he stopped and pointed, and I saw a small circle of burnt gra.s.s upon the ground. The tussocks were blackened and smouldering, and from the centre rose this line of smoke, pale, blue, steady. Then I noticed a movement of the atmosphere beside us, as if the warm air were rising and the cooler air rus.h.i.+ng in to take its place: a little centre of wind in the stillness. Overhead the boughs stirred and trembled where the smoke disappeared. Otherwise, not a tree sighed, not a sound made itself heard. The wood was still as a graveyard. A horrible idea came to me that the course of nature was about to change without warning, had changed a little already, that the sky would drop, or the surface of the earth crash inwards like a broken bubble. Something, certainly, reached up to the citadel of my reason, causing its throne to shake.

John Silence moved forward again. I could not see his face, but his att.i.tude was plainly one of resolution, of muscles and mind ready for vigorous action. We were within ten feet of the blackened circle when the smoke of a sudden ceased to rise, and vanished. The tail of the column disappeared in the air above, and at the same instant it seemed to me that the sensation of heat pa.s.sed from my face, and the motion of the wind was gone. The calm spirit of the fresh October day resumed command.

Side by side we advanced and examined the place. The gra.s.s was smouldering, the ground still hot. The circle of burned earth was a foot to a foot and a half in diameter. It looked like an ordinary picnic fireplace. I bent down cautiously to look, but in a second I sprang back with an involuntary cry of alarm, for, as the doctor stamped on the ashes to prevent them spreading, a sound of hissing rose from the spot as though he had kicked a living creature. This hissing was faintly audible in the air. It moved past us, away towards the thicker portion of the wood in the direction of our field, and in a second Dr. Silence had left the fire and started in pursuit.

And then began the most extraordinary hunt of invisibility I can ever conceive.

He went fast even at the beginning, and, of course, it was perfectly obvious that he was following something. To judge by the poise of his head he kept his eyes steadily at a certain level--just above the height of a man--and the consequence was he stumbled a good deal over the roughness of the ground. The hissing sound had stopped. There was no sound of any kind, and what he saw to follow was utterly beyond me. I only know, that in mortal dread of being left behind, and with a biting curiosity to see whatever there was to be seen, I followed as quickly as I could, and even then barely succeeded in keeping up with him.

And, as we went, the whole mad jumble of the Colonel's stories ran through my brain, touching a sense of frightened laughter that was only held in check by the sight of this earnest, hurrying figure before me.

For John Silence at work inspired me with a kind of awe. He looked so diminutive among these giant twisted trees, while yet I knew that his purpose and his knowledge were so great, and even in hurry he was dignified. The fancy that we were playing some queer, exaggerated game together met the fact that we were two men dancing upon the brink of some possible tragedy, and the mingling of the two emotions in my mind was both grotesque and terrifying.

He never turned in his mad chase, but pushed rapidly on, while I panted after him like a figure in some unreasoning nightmare. And, as I ran, it came upon me that he had been aware all the time, in his quiet, internal way, of many things that he had kept for his own secret consideration; he had been watching, waiting, planning from the very moment we entered the shade of the wood. By some inner, concentrated process of mind, dynamic if not actually magical, he had been in direct contact with the source of the whole adventure, the very essence of the real mystery. And now the forces were moving to a climax. Something was about to happen, something important, something possibly dreadful. Every nerve, every sense, every significant gesture of the plunging figure before me proclaimed the fact just as surely as the skies, the winds, and the face of the earth tell the birds the time to migrate and warn the animals that danger lurks and they must move.

In a few moments we reached the foot of the mound and entered the tangled undergrowth that lay between us and the sunlight of the field.

Here the difficulties of fast travelling increased a hundredfold. There were brambles to dodge, low boughs to dive under, and countless tree trunks closing up to make a direct path impossible. Yet Dr. Silence never seemed to falter or hesitate. He went, diving, jumping, dodging, ducking, but ever in the same main direction, following a clean trail.

Twice I tripped and fell, and both times, when I picked myself up again, I saw him ahead of me, still forcing a way like a dog after its quarry.

And sometimes, like a dog, he stopped and pointed--human pointing it was, psychic pointing, and each time he stopped to point I heard that faint high hissing in the air beyond us. The instinct of an infallible dowser possessed him, and he made no mistakes.

At length, abruptly, I caught up with him, and found that we stood at the edge of the shallow pond Colonel Wragge had mentioned in his account the night before. It was long and narrow, filled with dark brown water, in which the trees were dimly reflected. Not a ripple stirred its surface.

”Watch!” he cried out, as I came up. ”It's going to cross. It's bound to betray itself. The water is its natural enemy, and we shall see the direction.”

And, even as he spoke, a thin line like the track of a water-spider, shot swiftly across the s.h.i.+ny surface; there was a ghost of steam in the air above; and immediately I became aware of an odour of burning.

Dr. Silence turned and shot a glance at me that made me think of lightning. I began to shake all over.

”Quick!” he cried with excitement, ”to the trail again! We must run around. It's going to the house!”

The alarm in his voice quite terrified me. Without a false step I dashed round the slippery banks and dived again at his heels into the sea of bushes and tree trunks. We were now in the thick of the very dense belt that ran around the outer edge of the plantation, and the field was near; yet so dark was the tangle that it was some time before the first shafts of white sunlight became visible. The doctor now ran in zigzags.

He was following something that dodged and doubled quite wonderfully, yet had begun, I fancied, to move more slowly than before.

”Quick!” he cried. ”In the light we shall lose it!”

I still saw nothing, heard nothing, caught no suggestion of a trail; yet this man, guided by some interior divining that seemed infallible, made no false turns, though how he failed to crash headlong into the trees has remained a mystery to me ever since. And then, with a sudden rush, we found ourselves on the skirts of the wood with the open field lying in bright suns.h.i.+ne before our eyes.

”Too late!” I heard him cry, a note of anguish in his voice. ”It's out--and, by G.o.d, it's making for the house!”

I saw the Colonel standing in the field with his dogs where we had left him. He was bending double, peering into the wood where he heard us running, and he straightened up like a bent whip released. John Silence dashed pa.s.sed, calling him to follow.
