Until long after dark they sat and talked of the future, and of life and death, and of the soul and of the great mystery that had swept the earth clean of all of their kind and had left them, alone, of all those fifteen hundred million human creatures. And overhead, blotting out a patch of sky and stars, moved slowly the dark object which had so puzzled Stern since the first time he had observed it--the thing he meant to know about and solve, once he could reach the Cambridge Observatory. And of this, too, they talked; but neither he nor she could solve the riddle of its nature. Their talk together, that night, was typical of the relationship that had grown up between them in the long weeks since their awakening in the Tower. Almost all, if not quite all, the old-time idea of sex had faded--the old, false assumption on the part of the man that he was by his very nature the superior of woman. Stern and Beatrice now stood on a different footing; their friendship, comradeship and love were based on the tacit recognition of absolute equality, save for Stern's accidental physical superiority. It was as though they had been two men, one a little stronger and larger than the other, so far as the notion of equality went; though this by no means destroyed that magnetic sex-emotion which, in other aspects, thrilled and attracted and infused them both. Their love never for a moment obscured Stern's recognition of the girl as primarily a human being, his associate on even terms in this great game that they were playing together, this tremendous problem they were laboring to solve--the vastest and most vital problem that ever yet had confronted the human race, now represented in its totality by these two living creatures. And as Beatrice recalled the world of other times, with all its false conventions, limitations and pettily stupid gallantries, she shuddered with repulsion. In her heart she knew that, had the choice been hers, she would not have gone back to that former state of half-chattel patronage, half-hypocritical homage and total misconception. Contrasting her present state with her past one, and comparing this man--all ragged, unshaven and long-haired as he was, yet a true man in every inch of his lithe, virile body--with others she remembered, she found up-welling in her a love so deep and powerful, grounded on such broad bases of respect and gratitude, mutual interest and latent passion, that she herself could not yet understand it in all its phases and its moods. The relation which had grown up between them, comrades and partners in all things, partook of a fine tolerance, an exquisite and never-failing tenderness, a wealth of all intimate, yet respectful adoration. It held elements of brotherhood and parenthood; it was the love of coworkers striving toward a common goal, of companions in life and in learning, in striving, doing, accomplishing, even failing. Failure mattered nothing; for still the comradeship was there.
