Gilbert found the doctor in the great "saal" at the mills. He had his coat off and was scraping at bared arms for dear life. At each door stood a pair of stalwart sentinels, and several hundred mill workers were grouped about talking in low-voiced clusters. Only here and there one more diligent than the rest, or with quieter nerves, deftly passed sheets of white paper from hand to hand as if performing a conjuring trick.
The doctor spied Gilbert as he entered. They were excellent friends. "Man," he cried across the great room, looking down again instantly to his work, "run up to the surgery for another tube of vaccine like this. It is in B cabinet, shelf 6. And as you come back, wire for half-a-dozen more. You know where I get them!"
And Gilbert sped upon his first errand. After that he deserted his own lodgings, and he and Dr. Durie took hasty and informal meals when they could snatch a moment from work. Sundry cold edibles stood permanently on the doctor's oaken sideboard, and of these Gilbert and his host partook without sitting down. Then on a couch, or more often on a few rugs thrown on the floor, one or the other would snatch a hurried sleep.
There were twenty-six cases on Saturday—fifty-eight by the middle of the following week. Within the same period nine had terminated fatally, and there were others who could not possibly recover. Nurses came in from the great city hospitals, as they could be spared, but the demand far exceeded the supply, and Gilbert was indefatigable. Yet his laugh was cheery as ever, and even the delirious would start into some faint consciousness of pleasure at the sound of his voice.
But one day the young minister awoke with a racking head, a burning body, a dry throat, and the chill of ice in his bones.
"This is nothing—I will work it off," said Gibby; and, getting up, he dressed with haste and went out without touching food. The thought of eating was abhorrent to him. Nevertheless, he did his work all the forenoon, and went here and there with medicine and necessaries. He relieved a nurse who had been two nights on duty, while she slept for six hours. Then after that he set off home to catch Dr. Durie before he could be out again. For he had heard his host come in and throw himself down on the couch while he was dressing.
As he passed the front of Rescobie Manse, he looked up to wave a hand to Jemima, as he never forgot to do. Her father was still "indisposed," and Miss Girnigo was understood to be taking care of him. Yes, there she was among her flowers, and Gibby, hardly knowing what he did—being light-headed and racked with pain—openly kissed his hand to her within sight of half-a-score of Rescobie windows.
Then, his feet somehow tangling themselves and his knees failing him, he fell all his length in the hot dust of the highway.

When Gilbert Denholm came to himself he found a white-capped nurse sitting by the window of a room he had never before seen. There was a smell of disinfectants all about, which somehow seemed to have followed him through all the boundless interstellar spaces across which he had been wandering.
