"Two thousand, two thousand five hundred, three thousand feet!"
Still they seemed to be climbing all too slowly for the pilot. He had caught sight of the Zeppelin when she showed herself for a moment, and he had said to himself:
"Twelve thousand feet, and then there'll be a chance! But nothing less than that will do."
He was impatient therefore to get higher and higher, for he feared the raiders would discharge or jettison their cargo of bombs before he could get at them. They certainly would have done, had they known that at that very moment Himmelman's rival was climbing to meet them, on a Buckstead Bullet, which could do one hundred and thirty miles an hour when pushed.
Already a number of bombs had been dropped, and away to the northward several fires could be seen where the night-raiders had left their victims behind, in the shape of burning homesteads, where the victims were women and children, old men and invalids; but the avenger was at hand, and the hour of reckoning had come.
"Eight thousand, nine thousand feet!" clicked the indicator, though its voice was lost in the roar of the engine and propellor.
At eight thousand feet Dastral passed several of the 'planes which had preceded him, and at nine thousand he left the last of them behind him and entered into a bank of clouds. Never once had he ceased his rapid, climbing spirals, and now, through the misty, clinging vapour of the clouds he still soared heavenwards. Once or twice he stopped his engines just to listen for a few seconds, but he heard nothing except the whir-r-r-r of the 'planes beneath him.
He was ahead of them all now, for his engines were running beautifully, and the "Bullet" raced through the next layer of clouds as a fish darts through the waters. It was becoming lighter also, for he could catch glimpses of the stars, and the remaining clouds were thinner than those below. Soon, he would be above them all, and perhaps above the raider. It was cold too, bitterly cold, but his young blood coursed madly through his veins, and his heart beat quicker and quicker.
"Ten thousand. Eleven thousand," laughed the indicator, joining merrily in the hunt, for it seemed to Dastral now that he could hear those weird voices of the night, speaking to him and calling him up and up, ever higher and higher. Yes, the clouds and the stars were calling him, and the music and rhythm of that pulsating engine a few feet away, and the whir-r-r of those propellors just ahead, seemed to make him almost light-headed, so that he began to laugh and sing.
He thought of crooked Tim far down below, and what he had said about the romance and the music, and from the pilot's lips there fell involuntarily the words:
