"You're dreaming! Tell me about the barracks!"

And Mackenzie told him—briefly.

All night he and Mackenzie and Clarke worked over the new cases, resting by turns, and in the morning two other men were brought in. One was the trooper who had borne the summons to Trevelyan.

The cases developed slowly, and with an effort that had in it something of the supernatural, they kept it from spreading into the mow down of an epidemic. But the men were sick—sicker than any had yet been, and out of the proportion stricken, the mortality was frightful, and Death's twin brother, Fear, laid his heavy hand upon the district.

The men were good, on the whole, as to precautionary measures, for they held Mackenzie and even Clarke in wholesome awe, but they regarded Trevelyan with something greater still. They were ashamed before him—ashamed to mention their fear, or even think it, as he came and went among them, silent, commanding, and unmoved by fear.

Mackenzie or Clarke could not have spoken so to them—silently. They were at their own business. They were supposed and expected to meet disease and death, daily, hourly if necessary, and not be afraid. But Trevelyan was not a surgeon; he had come out to them to serve them in their extremity—voluntarily—without military command, and they grew to think of the scourge after a while as they would have looked upon a hostile tribe to be conquered—as an enemy to be vanquished for the Queen.

And as though the lessening of their panic was the sign for the dying out of the scourge, the cholera cases decreased as the days wore themselves away.

It was toward the end of the desperate fight that they had made that Mackenzie came in one day at dawn, to relieve Trevelyan's watch over the half dozen cases in his wing of the hospital. He noticed that Trevelyan looked oddly white, and that there was a drawn expression about his mouth and face.

"What is it," he asked. "Aren't you feeling well?"

"Why, yes; what made you ask?"
