But in spite of it all, her sense of pity seemed to be going. When the twenty-third came, and she read that another gallant young leader had been assassinated, she could not mourn him deeply. Though nothing could be stupider than to slay Michael Collins, his earth went on shining in the grave. She could not bring herself to assert that such a youth ought never to have been born. She had read a great deal in the papers about radio-telegraphy. Apparently the year 1922 would be remembered as the year when all the boys in America began to talk through empty space like gossiping seraphs. She wished that Horatio could have lived to see the day. How tickled she would have been to hear from Washington such words as these: “Get ready! Your brother Horatio is on the ether.” If all the boys in the world got acquainted with each other by such means, maybe peace would come after all—some day. Occasionally she had seen some reference to the deeper mystery of radium and its terrible, almost inconceivable energy. She earnestly hoped that nobody on earth was trying to find anything like it but greater in quantity. Given such a power, the savage human race would destroy itself in a year. Chapter 89. Actinium As she had no notion of Marvin’s being engaged in virtually that search, her will to refuse him continued to lose weight by fits and starts, like actinium. On the afternoon of Sunday, the twenty-seventh, she restlessly rowed round into the creek after white lilies. She gathered a score. Then, as she leaned from the dory and dipped her arm into the brown water, she caught sight of a speck of green gelatin on the stem of a lily, and lifted it in. It was hydra, and about ready to bud. She placed it in her cup, and presently the daughter parted from the mother. Hydra was virtually immortal, and would go on living as long as it could find food, which might be for a thousand years, and every time it was a little short of food it would produce another daughter. Such immortality was not worth having. Life that was worth anything was precarious. And the history of life on earth was the history of steadily decreasing fertility. Species ran out, families ran out, but always in the effort to get a finer product. A water lily, living but for days, was infinitely better than hydra. Chapter 90. Thorium She dropped the two animals back into the water and began to row homeward through the hush of the Sunday afternoon, her bashfulness returning. She could not understand why, having admitted so much, she still hung back.
