"Trevelyan lay on the floor."

Clarke who had heard the glass break, hurried in from the adjoining ward. Mackenzie looked up as he entered.

"Collapse?" asked Clarke briefly.

Mackenzie did not seem to hear him.

"Bring the salt—it's just a chance," he said.

The light deepened in the east and the sunrise crept into the ward of the hospital and turned its search light curiously on the group in the furthest corner of the ward, and on the still figure on the bed. All morning the sunlight lingered around there as though it wanted to help Mackenzie in his fight, and impart into the chill of the rigid figure, some of its own warmth, and when the afternoon shadows came and drew it off, it retreated lingeringly, loath to say "good-night."

The shadows deepened and the quietness of midnight fell over the weary Station and the outlying cholera hospital. Mackenzie continued to sit by the bed.

The quietness outside crept in to meet the silence of the ward, and the night lamp cast strange shadows on the wall, at which Mackenzie stared. Once or twice he got up and visited the other beds and leaned over the men. Most were pulling through and were sleeping. McHennessy was drowsy with the morphia. Then Mackenzie would go back and sit down again by Trevelyan's bed. At midnight, Clarke, with eyes heavy with sleep, came in. He did not speak but he looked down at Trevelyan and then up questionally to Mackenzie, and at the syringe and the salt lying near by.
