She nodded her head, and he passed off into the first of many convulsions, which gradually diminished in force and frequency. Jees Uck hung over him remembering his injunction and not daring to touch him. Once Amos grew restless and made as though to go into the kitchen; but a quick blaze from her eyes quelled him, and after that, save for his laboured breathing and charnel cough, he was very quiet. Bonner slept. The blink of light that marked the day disappeared. Amos, followed about by the woman's eyes, lighted the kerosene lamps. Evening came on. Through the north window the heavens were emblazoned with an auroral display, which flamed and flared and died down into blackness. Some time after that, Neil Bonner roused. First he looked to see that Amos was still there, then smiled at Jees Uck and pulled himself up. Every muscle was stiff and sore, and he smiled ruefully, pressing and prodding himself as if to ascertain the extent of the ravage. Then his face went stern and businesslike. "Jees Uck," he said, "take a candle. Go into the kitchen. There is food on the table--biscuits and beans and bacon; also, coffee in the pot on the stove. Bring it here on the counter. Also, bring tumblers and water and whisky, which you will find on the top shelf of the locker. Do not forget the whisky." Having swallowed a stiff glass of the whisky, he went carefully through the medicine chest, now and again putting aside, with definite purpose, certain bottles and vials. Then he set to work on the food, attempting a crude analysis. He had not been unused to the laboratory in his college days and was possessed of sufficient imagination to achieve results with his limited materials. The condition of tetanus, which had marked his paroxysms, simplified matters, and he made but one test. The coffee yielded nothing; nor did the beans. To the biscuits he devoted the utmost care. Amos, who knew nothing of chemistry, looked on with steady curiosity. But Jees Uck, who had boundless faith in the white man's wisdom, and especially in Neil Bonner's wisdom, and who not only knew nothing but knew that she knew nothing watched his face rather than his hands. Step by step he eliminated possibilities, until he came to the final test. He was using a thin medicine vial for a tube, and this he held between him and the light, watching the slow precipitation of a salt through the solution contained in the tube. He said nothing, but he saw what he had expected to see. And Jees Uck, her eyes riveted on his face, saw something too,--something that made her spring like a tigress upon Amos, and with splendid suppleness and strength bend his body back across her knee. Her knife was out of its sheaf and uplifted, glinting in the lamplight. Amos was snarling; but Bonner intervened ere the blade could fall. "That's a good girl, Jees Uck. But never mind. Let him go!"
