TWO:As the doctor concentrated upon a delayed tea, his mind lapsed into its usual condition of fretful scepticism. Gregg's idea that the Clockwork man represented a mystery, if not a miracle, enraged him. At forty a man does not readily welcome discoveries that may upset his own world of accepted facts, and Allingham had long since given up the habit of following the latest results of scientific investigation. Years ago he had made his own small researches, only to discover that others were making them at the same time. He had had his gleamings in common with all the other students of his year. Everybody was having gleamings then of vast possibilities in medical science, especially in the direction of nervous pathology and the study of morbid diseases resulting from highly complex methods of living. There had been much sound work, a good deal of irresponsible mud-raking, and, in Allingham's case, a growing suspicion that the human organism was not standing very well the strains imposed upon it by modern civilisation. He had wondered then if some experiments would not be made some day in[Pg 45] the pursuit of evolutionary doctrines as applied to physiological progress��but that had been the most ephemeral of all his gleams.Naturally the Tokaido is a place of activity, and in the ages that have elapsed since it was made many villages have sprang into existence along its sides. Between Yokohama and Tokio there is an almost continuous hedge of these villages, and there are places where you may ride for miles as along a densely filled street. From Tokio the road follows the shore of the bay until near Yokohama, when it turns inland; but it comes to or near the sea again in several places, and affords occasional glimpses of the great water. For several years after the admission of foreigners to Japan the Tokaido gave a great deal of trouble to the authorities, and figured repeatedly in the diplomatic history of the government. The most noted of these affairs was that in which an Englishman named Richardson was killed, and the government was forced to pay a heavy indemnity in consequence. A brief history of this affair may not be without interest, as it will illustrate the difficulties that arose in consequence of a difference of national customs.
