Not a score of yards farther they came to a passage in the wall, or, rather, a fissure through it, which seemed to have been floored by the hand of man at some distant time. It led at right angles from the crater shelf. As Polaris looked into it he could see that it was lighted dimly by the light of day. It was barely wide enough for the passage of the sledge, and it so twisted in the rock that it had been a slow and difficult task for the priest to drive the ponies through.
Circumstance willed that they were not to pass the tunnel without further mishap and bloodshed.
Slowly the enemy had crept up. When Kalin and Polaris broke cover and dashed for the mouth of the tunnel, the foremost of the Sardanians was only a short spear-throw behind. In the momentary pause at the mouth of the tunnel, men and dogs were bunched, and offered a fair target to the Sardanians leaping along the ledge.
With a scream of pain and rage, the dog Pallas leaped thrice her height from the floor and fell, writhing in her death agonies. A spear had penetrated behind the poor brute's shoulder, nearly piercing the body through.
Her death wail was drowned in the terrible challenge that came from the throats of the pack, and the cry of anger that rose from the lips of her master. Kalin stood alone at the mouth of the narrow way, holding the rifle that had been thrust into his hands. In the midst of his leaping, snarling dogs, Polaris, raging like a demon at the slaughter of his old playmate and servant, threw himself back into the teeth of the charge of Minos's men.
Clutching a heavy spear in his right hand, and whirling it like a toy, and with a revolver in his left, he swept down the ledge, thrusting and firing. Around him the six dogs of the pack fought after their own fashion, rending and snapping like devils.
In the face of that attack the Sardanians shrank aghast.
Thirty feet or more back along the pathway Polaris fought blindly for vengeance before his reason returned to him. In front of him the Sardanians were huddled in the path, backing away and obstructed in their flight by those behind who were pushing forward, under the threats and commands of Minos, the Prince.
Polaris's brain cleared. He heard the voice of Kalin calling to him to return. He turned and raced swiftly to the tunnel, over the bodies of the dead. Behind him the rush of pursuit gathered and came on again.
Through the tunnel they raced, dogs and men, and came out into the sunlight, which shone on crags and boulders and bare earth.
