The letters continued at the rate of one every two or three weeks. They were picked up by Mrs. Bagley who let it be known that these were progress reports. In reality, they were little tracts on the theory of child education. They kept up the correspondence for the information it contained, and also because Mrs. Bagley enjoyed this contact with an outer world that contained adults. Meanwhile, James ended his spurt of growth and settled down. Work on his machine continued when he could afford to buy the parts, and his writing settled down into a comfortable channel once more. In his spare time James began to work on Martha's diction. Martha could not have been called a retarded child. Her trouble was lack of constant parental attention during her early years. With father gone and mother struggling to live, Martha had never overcome some of the babytalk-diction faults. There was still a trace of the omitted 'B' here and there. 'Y' was a difficult sound; the color of a lemon was "Lellow." Martha's English construction still bore marks of the baby. "Do you have to--" came out as "Does you has to--?" James Holden's father had struggled in just this way through his early experimental days, when he despaired of ever getting the infant James out of the baby-prattle stage. He could not force, he could not even coerce. All that his father could do was to watch quietly as baby James acquired the awareness of things. Then he could step in and supply the correct word-sound to name the object. In those early days the progress of James Holden was no greater than the progress of any other infant. Holden Senior followed the theory of ciphers; no cryptologist can start unravelling a secret message until he is aware of the fact that some hidden message exists. No infant can be taught a language until some awareness tells the tiny brain that there is some definite connection between sound and sight. * * * * * For the next few weeks James worked with Martha on her speech, and hated it. So slow, so dreary! But it was necessary, he thought, to keep her from establishing any more permanent errors, so that when the machine was ready there would be at least a blank slate to write on, not one all scribbled over with mistakes. Time passed; the weather grew colder; the machine spread its scattered parts over his workroom. Janet Bagley knew that the machine was growing, but it had not occurred to her that it would be finished. She had grown accustomed to her life on Martin's Hill. By her standards, it was easy. She made three meals each day, cleaned the rooms, hung curtains, sewed clothing for Martha and herself, did the shopping and had time enough left over to take excursions in her little car and keep her daughter out of mischief. It was pleasant. It was more than pleasant, it was safe. And then the machine was finished.
