In those six months he worked at many jobs and developed into a very good imitation of a genuine worker. He was a natural linguist, and he kept notebooks, making a scientific study of the workers’ slang or argot, until he could talk quite intelligibly. This language also enabled him more intimately to follow their mental processes, and thereby to gather much data for a projected chapter in some future book which he planned to entitle _Synthesis of Working-Class Psychology_. Before he arose to the surface from that first plunge into the underworld he discovered that he was a good actor and demonstrated the plasticity of his nature. He was himself astonished at his own fluidity. Once having mastered the language and conquered numerous fastidious qualms, he found that he could flow into any nook of working-class life and fit it so snugly as to feel comfortably at home. As he said, in the preface to his second book, _The Toiler_, he endeavoured really to know the working people, and the only possible way to achieve this was to work beside them, eat their food, sleep in their beds, be amused with their amusements, think their thoughts, and feel their feeling. He was not a deep thinker. He had no faith in new theories. All his norms and criteria were conventional. His Thesis on the French Revolution was noteworthy in college annals, not merely for its painstaking and voluminous accuracy, but for the fact that it was the dryest, deadest, most formal, and most orthodox screed ever written on the subject. He was a very reserved man, and his natural inhibition was large in quantity and steel-like in quality. He had but few friends. He was too undemonstrative, too frigid. He had no vices, nor had any one ever discovered any temptations. Tobacco he detested, beer he abhorred, and he was never known to drink anything stronger than an occasional light wine at dinner. When a freshman he had been baptized “Ice-Box” by his warmer-blooded fellows. As a member of the faculty he was known as “Cold-Storage.” He had but one grief, and that was “Freddie.” He had earned it when he played full-back in the ‘Varsity eleven, and his formal soul had never succeeded in living it down. “Freddie” he would ever be, except officially, and through nightmare vistas he looked into a future when his world would speak of him as “Old Freddie.” For he was very young to be a doctor of sociology, only twenty-seven, and he looked younger. In appearance and atmosphere he was a strapping big college man, smooth-faced and easy-mannered, clean and simple and wholesome, with a known record of being a splendid athlete and an implied vast possession of cold culture of the inhibited sort. He never talked shop out of class and committee rooms, except later on, when his books showered him with distasteful public notice and he yielded to the extent of reading occasional papers before certain literary and economic societies.
