My experiences since I waked up in this year 2000 might be said to have consisted of a succession of instantaneous mental readjustments of a revolutionary character, in which what had formerly seemed evil to me had become good, and what had seemed wisdom had become foolishness. Had this conversation about the strikers taken place anywhere else, the entirely new impression I had received of the part played by them in the great social revolution of which I shared the benefit would simply have been one more of these readjustments, and the process entirely a mental one. But the presence of this wondrous group, the lifelikeness of the figures growing on my gaze as I listened to the doctor's words, imparted a peculiar personal quality--if I may use the term--to the revulsion of feeling that I experienced. Moved by an irresistible impulse, I rose to my feet, and, removing my hat, saluted the grim forms whose living originals I had joined my contemporaries in reviling. The doctor smiled gravely. "Do you know, my boy," he said, "it is not often that the whirligig of Time brings round his revenges in quite so dramatic a way as this?" CHAPTER XXVI. FOREIGN COMMERCE UNDER PROFITS; PROTECTION AND FREE TRADE, OR BETWEEN THE DEVIL AND THE DEEP SEA. We arrived at the Arlington School some time before the beginning of the recitation which we were to attend, and the doctor took the opportunity to introduce me to the teacher. He was extremely interested to learn that I had attended the morning session, and very desirous to know something of my impressions. As to the forthcoming recitation, he suggested that if the members of the class were aware that they had so distinguished an auditor, it would be likely to embarrass them, and he should therefore say nothing about my presence until the close of the session, when he should crave the privilege of presenting his pupils to me personally. He hoped I would permit this, as it would be for them the event of a lifetime which their grandchildren would never tire of hearing them describe. The entrance of the class interrupted our conversation, and the doctor and myself, having taken our seats in a gallery, where we could hear and see without being seen, the session at once began. "This morning," said the teacher, "we confined ourselves for the sake of clearness to the effects of the profit system upon a nation or community considered as if it were alone in the world and without relations to other communities. There is no way in which such outside relations operated to negative any of the laws of profit which were brought out this morning, but they did operate to extend the effect of those laws in many interesting ways, and without some reference to foreign commerce our review of the profit system would be incomplete.
