In a year or two he knew he would have to clear land and make preparations for agriculture. A grist-mill would soon be essential. He could not always depend upon the woods and streams for food for the colony.
There must be cultivation of fruits and grains; the taming of wild fowl, cattle, horses, sheep and goats--but no swine; and a regular evolution up through the stages again by which the society of the past had reached its climax.
And to his ears the whirring of his turbine as the waters of New Hope River swirled through the penstocks, the spinning of the wheels, the slapping of the deerskin belting, made music only second to the voices of Beatrice and his son.
Allan brought piecemeal and fitted up a small dynamo from some extensive ruins to southeastward. He brought wiring and several still intact incandescent lights. Before long Cliff Villa shone resplendent, to the awe and marvel of the Folk.
But Allan made no mystery of it. He explained it all to Zangamon, Bremilu and H'yemba, the smith; and when they seemed to understand, bade them tell the rest.
Thus every day some new improvement was installed, or some fresh knowledge spread among the colonists.
June had drawn on again, and the hot weather had become oppressive, before Allan thought once more of still further trips into the Abyss. Beatrice tried to dissuade him. Her heart shrank from further separation, risk and fear.
"Listen, dearest," she entreated as they sat by young Allan's bedside, one sultry, breathless night. "I think you've risked enough; really I do. You've got a boy now to keep you here, even if I can't! Please don't go! Follow out the plan you spoke to me about yesterday, but don't go yourself!"
"The plan?"
"Yes, you know. Your idea of training three or four of the most intelligent men to fly, and perhaps building one or two more planes--that is, establishing a regular service to and from the Abyss. That would be so much wiser, Allan! Think how deadly imprudent it is for you, you personally, to take this risk every time! Why, if anything should happen--"
"But it won't! It can't!"
"--What would become of the colony? We haven't got anything like enough of a start to go ahead with, lacking you! I speak now without sentiment or foolish, womanly fears, but just on a common-sense, practical basis. Viewed at that angle, ought you to take the risk again?"
"There's no time now, darling, to build more planes! No time to teach flying! We've got to recruit the colony as fast as possible, in case of emergencies. Why, I haven't made a trip since--since God knows when! It's time I was off now!"
