The sun rose higher, baking down on the bare slopes with an intolerable heat. Silence brooded like an evil monster over the land. They had seen nothing, but Kane could have sworn at times that a black shadow drifted behind a boulder at their approach.
"Them vampires, they stay hid in daytime." said N'Longa with a low laugh. "They be afraid of one fellow vulture! No fool vulture! He know death when he see it! He pounce on one fellow dead man and tear and eat if he be lying or walking!"
A strong shudder shook his companion.
"Great God!" Kane cried, striking his thigh with his hat; "is there no end to the horror of this hideous land? Truly this land is dedicated to the powers of darkness!"
Kane's eyes burned with a dangerous light. The terrible heat, the solitude and the knowledge of the horrors lurking on either hand were shaking even his steely nerves.
"Keep on one fellow hat, blood-brother," admonished N'Longa with a low gurgle of amusement. "That fellow sun, he knock you dead, suppose you no look out."
Kane shifted the musket he had insisted on bringing and made no reply. They mounted an eminence at last and looked down on a sort of plateau. And in the centre of this plateau was a silent city of grey and crumbling stone. Kane was smitten by a sense of incredible age as he looked. The walls and houses were of great stone blocks, yet they were falling into ruin. Grass grew on the plateau, and high in the streets of that dead city. Kane saw no movement among the ruins.
"That is their city—why do they choose to asleep in the caves?"
"Maybe-so one fellow stone fall on them from roof and crush. Them stone huts, he fall down bimeby. Maybe-so they no like to stay together—maybe-so they eat each other, too."
"Silence!" whispered Kane; "how it hangs over all!"
"Them vampires no talk nor yell; they dead. They sleep in caves, wander at sunset and at night. Maybe-so them fellow bush tribes come with spears, them vampires go to stone kraal and fight behind walls."
Kane nodded. The crumbling walls which surrounded that dead city were still high and solid enough to resist the attack of spearmen—especially when defended by these snout-nosed fiends.
"Blood-brother," said N'Longa solemnly, "I have mighty magic thought! Be silent a little while."
Kane seated himself on a boulder, and gazed broodingly at the bare crags and slopes which surrounded them. Far away to the south he saw the leafy green ocean that was the jungle. Distance lent a certain enchantment to the scene. Closer at hand loomed the dark blotches that were the mouths of the caves of horror.
N'Longa was squatting, tracing some strange pattern in the clay with a dagger point. Kane watched him, thinking how easy they might fall victim to the vampires if even three or four of the fiends should come out of their caverns. And even as be thought it, a black and horrific shadow fell across the crouching fetish-man.
Kane acted without conscious thought. He shot from the boulder where he sat—like a stone hurled from a catapult, and his musket stock shattered the face of the hideous thing who had stolen upon them. Back and back Kane drove his inhuman foe staggering, never giving him time to halt or launch an offensive, battering him with the onslaught of a frenzied tiger.
At the very edge of the cliff the vampire wavered, then pitched back over, to fall for a hundred feet and lie writhing on the rocks of the plateau below. N'Longa was on his feet pointing; the hills were giving up their dead.
Out of the caves they were swarming, the terrible black silent shapes; up the slopes they came charging and over the boulders they came clambering, and their red eyes were all turned toward the two humans who stood above the silent city. The caves belched them forth in an unholy judgment day.
N'Longa pointed to a crag some distance away and with a shout started running fleetly toward it. Kane followed. From behind boulders taloned hands clawed at them, tearing their garments. They raced past caves, and mummied monsters came lurching out of the dark, gibbering silently, to join in the pursuit.
The dead hands were close at their back when they scrambled up the last slope and stood on a ledge which was the top of the crag. The fiends halted silently a moment, then came clambering after them. Kane clubbed his musket and smashed down into the red-eyed faces, knocking aside the upleaping hands. They surged up like a great wave; he swung his musket in a silent fury that matched theirs. The wave broke and wavered back; came on again.
He—could—not—kill—them! These words beat on his brain like a sledge on an anvil as he shattered wood-like flesh and dead bone with his smashing swings. He knocked them down, hurled them back, but they rose and came on again. This could not last—what in God's name was N'Longa doing? Kane spared one swift, tortured glance over his shoulder. The fetish-man stood on the highest part of the ledge, head thrown back, arms lifted as if in invocation.
