"He is the two thousand three hundred and forty-seventh Sacner Carfon in direct male line of descent," she explained. "But perhaps Six has not explained these things to you. Our population must not be allowed to increase, therefore each couple can have only two children. It is customary for the boy to be born first, and is given the name of his father. The girl is younger, and is given her mother's name." "That will now be changed," said Carfon feelingly. "These visitors have given us the secret of power, and we shall be able to build new cities and populate Dasor as she should he populated." "Really?----" She checked herself, but a flame leaped to her eyes, and her voice was none too steady as she addressed the visitors. "For that we Dasorians thank you more than words can express. Perhaps you strangers do not know what it means to want a dozen children with every fiber of your being and to be allowed to have only two--we do, all too well--I will call Seven." She pressed a button, and up out of the opening in the middle of the floor there shot a half-grown boy, swimming so rapidly that he scarcely touched the coaming as he came to his feet. He glanced at the four visitors, then ran up to Seaton and Crane. "Please, sirs, may I ride, just a little short ride, in your vessel before you go away?" This was said in their language. "Seven!" boomed Carfon sternly, and the exuberant youth subsided. "Pardon me, sirs, but I was so excited----" "All right, son, no harm done at all. You bet you'll have a ride in the _Skylark_ if your parents will let you." He turned to Carfon. "I'm not so far beyond that stage myself that I'm not in sympathy with him. Neither are you, unless I'm badly mistaken." "I am very glad that you feel as you do. He would be delighted to accompany us down to the office, and it will be something to remember all the rest of his life." "You have a little girl, too?" Dorothy asked the woman. "Yes--would you like to see her? She is asleep now," and without waiting for an answer, the proud Dasorian mother led the way into a bedroom--a bedroom without beds, for Dasorians sleep floating in thermostatically controlled tanks, buoyed up in water of the temperature they like best, in a fashion that no Earthly springs and mattresses can approach. In a small tank in a corner reposed a baby, apparently about a year old, over whom Dorothy and Margaret made the usual feminine ceremony of delight and approbation. * * * * * Back in the living room, after an animated conversation in which much information was exchanged concerning the two planets and their races of peoples, Carfon drew six metal goblets of distilled water and passed them around. Standing in a circle, the six touched goblets and drank.
