The Yearly Tribute
"FOR science is a cruel mistress. She exacts a yearly tribute of flesh and blood like the dragons of ancient pagan mythology."
The eminent scientist paused momentarily here and viewed the earnest young faces before him. In this poetic figure of speech he saw fit to present to them the hardships of the life they had chosen to embark upon. It was a hot June morning, and the heavy scent of syringa came in through the high uncurtained windows of the lecture-hall. All the students stared with reverence at this distinguished stranger, who had come a long distance to speak to the graduating class; and one of its members sighed deeply and turned his eyes to the window, and watched some maple leaves moving languidly against the blue sky. The lecturer heard his sigh, saw him fall into abstraction, realized the peculiar character of his face; and marked him as a man who would serve to the end, possibly becoming one of the victims of that cruel mistress.
Pilchard and Swan had stopped to rest in the middle of the plaza. The black Mexican night was falling and a few stars blossomed in the sky, but there was no abatement in the heat which had held since sunrise; rather, indeed, the thickness of the atmosphere seemed intensified. The two Americans, who had spent a whole year in Mexico and become accustomed to the climate, attempted to make themselves comfortable. Pilchard sank to a dilapidated bench and lighted a cigarette; and Swan, not having even sufficient spirit to smoke, stretched himself bodily on the flat stones which paved the plaza, and placed his old hat upon his upturned face.
Both young men seemed depressed, and without speaking they listened to the moaning of the ocean which heaved and glistened in the distance; and when Pilchard finally said, "So poor Murphy is gone too," and Swan responded, "His troubles are over, poor fellow," it showed how completely they had been absorbed in the same thought.
"And Mulligan last week," Pilchard continued, "and all the others who went before, and Peele taken sick this afternoon. Swan, we're the only white men left."
"And we've only got ten days left."
"Oh, I guess we can do it, so long as we're out of the swamp."
"So long as the swamp isn't in us."
They were alluding to the railroad they had come to Mexico to build. The time-limit given in the contract would expire in ten days, and it would be a race to get the tracks through the town and down to the new docks in that time. Swan, whenever he thought of it, became restless, and now he sat up with a jerk, and his old hat slipped off his face. Even in that dim light Swan's ugliness was apparent. He measured over six feet and was loose-jointed and ungainly; he had big flat feet, and big bony, capable hands; and his features, which were big and bony too, seemed in proportion to nothing but his general ungainliness. Swan was an inventive Yankee with no background and no tradition. He could not even claim the proverbial Connecticut farm. His people had been dreary commercials in a middle-sized New Hampshire town, and he had worked his way through college to fit himself for a scientific career. His memory of his deceased parents was so colorless that it seemed to Swan as if they had never existed, and his contacts had been so dull, his outlook so dreary, that he had almost no conception of beauty. His plain college room, where, by the hour, he had worked out mathematical problems, and a grimy engine-room (which was the next stage of his advancement), where he had stood in a greasy black shirt, surrounded by
