"Having made his brain record, about which I have told you, he and his companion--for she has in similar fashion turned over her work to her successor--retire to the Country of Age, where they rest and relax after their century of effort. They do whatever they care to do, for as long as they please to do it. Finally, after assuring themselves that all is well with the children, they decide that they are ready for the Change. Then, side by side as they have labored, they pass." Now at the door of the observatory, Dorothy paused and shrank back against Seaton, her eyes widening as she stared at Orlon. "No, daughter, why should we fear the Change?" he answered her unspoken question, calm serenity in every inflection of his quiet voice. "The life-principle is unknowable to the finite mind, as is the All-Controlling Force. But even though we know nothing of the sublime goal toward which it is tending, any person ripe for the Change can, and of course does, liberate the life-principle so that its progress may be unimpeded." * * * * * In a spacious room of the observatory, in which the Terrestrials and their Norlaminian hosts had been long engaged in study and discussion, Seaton finally rose and extended a hand toward his wife. "Well, that's that, then, Orlon, I guess. We've been thirty hours without sleep, and for us that's a long time. I'm getting so dopey I can't think a lick. We'd better go back to the _Skylark_ and turn in, and after we've slept nine hours or so I'll go over to Rovol's laboratory and Crane'll come back here to you." "You need not return to your vessel," said Orlon. "I know that its somewhat cramped quarters have become irksome. Apartments have been prepared here for you. We shall have a meal here together, and then we shall retire, to meet again tomorrow." As he spoke, a tray laden with appetizing dishes appeared in the air in front of each person. As Seaton resumed his seat the tray followed him, remaining always in the most convenient position. Crane glanced at Seaton questioningly, and Satrazon, the First of Chemistry, answered his thought before he could voice it. "The food before you, unlike that which is before us of Norlamin, is wholesome for you. It contains no copper, no arsenic, no heavy metals--in short, nothing in the least harmful to your chemistry. It is balanced as to carbohydrates, proteins, fats and sugars, and contains the due proportion of each of the various accessory nutritional factors. You will also find the flavors are agreeable to each of you." "Synthetic, eh? You've got us analyzed," Seaton stated, rather than asked, as with knife and fork he attacked the thick, rare, and beautifully broiled steak which, with its mushrooms and other delicate trimmings, lay upon his rigid although unsupported tray--noticing as he did so that the Norlaminians ate with tools entirely different from those they had supplied to their Earthly guests.
