Zenas found that there were a number of chambers below the ground level of the structure. In the central one of them he bestowed his precious cakes, and with them the end of his copper wire. He directed his assistants to cover the whole over with heavy stones.
"And handle them with care," he cautioned, "or you will come a lot closer to the stars than you are ever likely to be by any other means."
His preparations completed, the geologist bade his henchmen to make themselves scarce, which they were very glad to do. Bidding every one in the neighborhood of the tower to withdraw to a distance of several hundred feet, Zenas uncoiled his wire, of which he had brought a quantity sufficient to keep him out of harm's way. He squatted down behind the bole of a big yew-tree and struck the knob of his battery.
For an instant nothing happened, and Zenas, peering forth from behind his tree, felt his heart sink with disappointment. Then very quietly the entire structure of the tower, which was nearly seventy feet in height, quitted the earth. For a second it seemed to hang suspended in the air like some enchanted thing. A hollow booming reverberated across the plain. The tower flew into fragments. The ice-bound surface of the Illia was shattered by the falling rocks. A gust of air rushed across the plain and through the ranks of the Rutharian soldiery and with it a shower of smaller débris, which fell among them like a storm. From the spot where the tower had stood, a column of greenish-yellow smoke arose and hung heavily.
From the camp and the crowds of citizens went up a low moan of awe, followed by a shout of triumph from thirty thousand throats. Men ran across the meadows to view the aftermath of this wonder—such a thing as never had been seen in Ruthar. Where the tower had stood was a hole in the earth, wherein the structure itself might almost have been buried. No vestige of the masonry was left. Not one stone remained upon another, and many of the larger foundation rocks had been sundered into fragments by the terrific force of the released gases of the melinite.
Rutharians from that day on called Zenas Wright "Father of the Thunders," and accorded him a respect second only to that in which they held Polaris.
Janess, the red captain, and Everson, who had been witnesses to his experiment, ran to the side of the geologist and wrung his hand.
"And now do you, Father Zenas, stay away from that laboratory," said Oleric.
"See to it that my men keep to the trick of making this stuff; but do you keep away. Some careless fellow might let a cake of your earth-shaker fall—and we cannot spare you."
"Now show me this Kimbrian Wall," was the comment of Zenas. But the scientist yielded to the entreaties of his friends, and thereafter went no more to the laboratories, except once a day only, to test the purity of the chemicals with which his workmen wrought.
