"Lions!" muttered Conan.

"Aye. By day they are kept in subterranean caverns below the tower. That's why there are no guards in this garden."

Conan counted the eyes rapidly.

"Five in sight; maybe more back in the bushes. They'll charge in a moment—"

"Be silent!" hissed Taurus, and he moved out from the wall, cautiously as if treading on razors, lifting the slender tube. Low rumblings rose from the shadows and the blazing eyes moved forward. Conan could sense the great slavering jaws, the tufted tails lashing tawny sides. The air grew tense — the Cimmerian gripped his sword, expecting the charge and the irresistible hurtling of giant bodies. Then Taurus brought the mouth of the tube to his lips and blew powerfully. A long jet of yellowish powder shot from the other end of the tube and billowed out instantly in a thick green-yellow cloud that settled over the shrubbery, blotting out the glaring eyes.

Taurus ran back hastily to the wall. Conan glared without understanding. The thick cloud hid the shrubbery, and from it no sound came.

"What is that mist?" the Cimmerian asked uneasily.

"Death!" hissed the Nemedian. "If a wind springs up and blows it back upon us, we must flee over the wall. But no, the wind is still, and now it is dissipating. Wait until it vanishes entirely. To breathe it is death."

Presently only yellowish shreds hung ghostily in the air; then they were gone, and Taurus motioned his companion forward. They stole toward the bushes, and Conan gasped. Stretched out in the shadows lay five great tawny shapes, the fire of their grim eyes dimmed for ever. A sweetish cloying scent lingered in the atmosphere.
