On the far side, in a wide, open stretch that served the children sometimes as a playground, stood the great hangars of the community's air-fleet. Beyond them rose workshops, their machinery driven by electric power from the turbines at the rapids.
Even as Allan and Beatrice passed through the cheering crowd, now drifting toward the hangars, a sound of music wafted down-wind--a little harsh at times, but still with promise of far better things to be.
Many flags fluttered in the air, and even the rollicking children on the lawns paused to wonder as swift shadows cut across the park.
On high was heard the droning hum of the propellers. It ceased, and in wide, sure, evenly balanced spirals the great planes one by one slid down and took the earth as easily as a gull sinks to rest upon the bosom of a quiet sea.
“They do work well, my equilibrators!” murmured Allan, unable to suppress a thrill of pride. “Simple, too; but, after all, how wonderfully effective!”
The crowd parted to let him through with Beatrice. Two minutes later he was clasping the hands of the last Folk ever to be brought from the strange, buried village under the cliff beside the Sunless Sea.
He summoned Zangamon and Frumuos, together with Sivad and the three aviators.
“Well done!” said he; and that was all--all, yet enough. Then, while the people cheered again and, crowding round, greeted their kinsfolk, he gave orders for the housing and the care of the travel-wearied newcomers.
Through the summer air drifted slow smoke. Off on the edge of the grove that flanked the plaza to southward the crackling of new-built fires was heard.
Allan turned to Beta with a smile.
