I planned carefully. I did not care to face the sarcasm of the great van Manderpootz; therefore I would work in secret. I would visit his laboratory at such times as he had classes or lectures, and I would use the attitudinizor to study the viewpoint of Carter, and to, as it were, practice that viewpoint. Thus I would have the means at hand of testing my progress, for all I had to do was glance at Miss Fitch without the attitudinizor. As soon as I began to perceive in her what Carter saw, I would know that success was imminent.

Those next two weeks were a strange interval of time. I haunted the laboratory of van Manderpootz at odd hours, having learned from the University office what periods he devoted to his courses. When one day I found the attitudinizor missing, I prevailed on Carter to show me where it was kept, and he, influenced doubtless by my friendship for the man he practically worshipped, indicated the place without question. But later I suspect that he began to doubt his wisdom in this, for I know he thought it very strange for me to sit for long periods staring at him; I caught all sorts of puzzled questions in his mind, though as I have said, these were hard for me to decipher until I began to learn Carter's personal system of symbolism by which he thought. But at least one man was pleased — my father, who took my absences from the office and neglect of business as signs of good health and spirits, and congratulated me warmly on the improvement.

But the experiment was beginning to work, I found myself sympathizing with Carter's viewpoint, and little by little the mad world in which he lived was becoming as logical as my own. I learned to recognize colors through his eyes; I learned to understand form and shape; most fundamental of all, I learned his values, his attitudes, his tastes. And these last were a little inconvenient at times, for on the several occasions when I supplemented my daily calls with visits to van Manderpootz in the evening, I found some difficulty in separating my own respectful regard for the great man from Carter's unreasoning worship, with the result that I was on the verge of blurting out the whole thing to him several times. And perhaps it was a guilty conscience, but I kept thinking that the shrewd blue eyes of the professor rested on me with a curiously suspicious expression all evening.
