"'My beloved child,' said Quong Lee, exhibiting the regulation tiny phial of romance containing a few drops of a white liquid, 'here is a poison ten-fold more subtle and deadly than that ejected from the fangs of the cruel serpent of the plain. The merest scratch from a weapon dipped in it will effect instant death. The victim curls up as a tender leaf in the midday sun. Yet it may be taken into the stomach with impunity. Strange, is it not? The minute quantity that you see here is all that I possess, and I shall feel honored if you will accept it. But,' he added, clutching Ah Moy by the wrist, 'should trouble come, remember that I--Quong Lee----' "'Trust me for that, venerable Uncle of the Moon; your name shall not be breathed in the matter, whatever happens. Ah Moy is not the man to bring misfortune upon the lifelong friend of his father,' and the fiendish chuckle which accompanied this remark filled the merchant-chemist with alarm. "'A million thanks, O Illustrious,' continued Ah Moy, pocketing the phial. 'I shall never forget your generosity. In good time I shall repay. Ah Moy will not prove ungrateful. Pardon this brief visit, O revered wearer of the crimson blouse. We meet again to-night. Bathed in the glow of thy approving smile, I leave thee. We meet again to-night, to-night. For the present, farewell. And I say, old 'un, you were dead wrong about that last game. You get a little dippy toward morning, don't you? Most old folks do. Ta, ta.' He glided out, slamming the door behind him. "Quong Lee followed his guest to the street, and watched his retreating figure until lost to sight. "'Curse him! Curse him!' hissed the old man vindictively. 'May the gods destroy him! And Quong Lee will aid them! Give me but the chance; oh, give me but the chance!' And he crossed his fingers. "The subject of this cheerful soliloquy returned without delay to Sam Yen's, who welcomed him with a wan smile, and after explaining some minor details of the work, crept off to his cot. Ah Moy immediately began his self-imposed task, and worked with a will, crooning the while a quaint Celestial air. It was ironing day at Sam Yen's, and the new hand did not object particularly to that part of the process. By a quarter after four he had completed the job, and surveyed with much satisfaction the neat bundles, duly ranged on the shelves. "Dennis Coogan arrived at dusk, and throwing down his ticket and some small change on the counter, walked off with his parcel, mumbling something uncomplimentary about the dirty haythin' who kept honest folks waitin' for their clothin'. Later in the evening Sam Yen appeared, much refreshed, and relieved his kind assistant. Ah Moy then left, cutting short the thanks of his countryman.
