Here and there the sunlight shot in with vivid spots of white light, dazzling the sight, but only making the surrounding gloom deeper by contrast. And on two occasions we passed dark circular places in the grass where fires had eaten their mark and left a ring of ashes. Dr. Silence pointed to them, but without comment and without pausing, and the sight of them woke in me a singular realisation of the dread that lay so far only just out of sight in this adventure.
It was exhausting work, and heavy going. We kept close together. The warmth, too, was extraordinary. Yet it did not seem the warmth of the body due to violent exertion, but rather an inner heat of the mind that laid glowing hands of fire upon the heart and set the brain in a kind of steady blaze. When my companion found himself too far in advance, he waited for me to come up. The place had evidently been untouched by hand of man, keeper, forester or sportsman, for many a year; and my thoughts, as we advanced painfully, were not unlike the state of the wood itself—dark, confused, full of a haunting wonder and the shadow of fear.
By this time all signs of the open field behind us were hid. No single gleam penetrated. We might have been groping in the heart of some primeval forest. Then, suddenly, the brambles and tussocks and stringlike grass came to an end; the trees opened out; and the ground began to slope upwards towards a large central mound. We had reached the middle of the plantation, and before us stood the broken Druid stones our host had mentioned. We walked easily up the little hill, between the sparser stems, and, resting upon one of the ivy-covered boulders, looked round upon a comparatively open space, as large, perhaps, as a small London Square.
Thinking of the ceremonies and sacrifices this rough circle of prehistoric monoliths might have witnessed, I looked up into my companion’s face with an unspoken question. But he read my thought and shook his head.
“Our mystery has nothing to do with these dead symbols,” he said, “but with something perhaps even more ancient, and of another country altogether.”
“Egypt?” I said half under my breath, hopelessly puzzled, but recalling his words in my bedroom.
He nodded. Mentally I still floundered, but he seemed intensely preoccupied and it was no time for asking questions; so while his words circled unintelligibly in my mind I looked round at the scene before me, glad of the opportunity to recover breath and some measure of composure. But hardly had I time to notice the twisted and contorted shapes of many of the pine trees close at hand when Dr. Silence leaned over and touched me on the shoulder. He pointed down the slope. And the look I saw in his eyes keyed up every nerve in my body to its utmost pitch.
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 shell 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 grass 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 rushing 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 attitude 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 passed 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 grass 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
