clearly. Men who read too hard, and slept too little, he
knew were sometimes troubled with very vivid hallucinations. Again he
calmly reviewed every incident of the night; his accurate sensations;
the vivid details; the emotions stirred in him; the dreadful feast--no
single hallucination could ever combine all these and cover so long a
period of time. But with less satisfaction he thought of the recurring
faintness, and curious sense of horror that had once or twice come over
him, and then of the violent pains in his arm. These were quite
unaccountable.

Moreover, now that he began to analyse and examine, there was one other
thing that fell upon him like a sudden revelation: _During the whole
time Field had not actually uttered a single word!_ Yet, as though in
mockery upon his reflections, there came ever from that inner room the
sound of the breathing, long-drawn, deep, and regular. The thing was
incredible. It was absurd.

Haunted by visions of brain fever and insanity, Marriott put on his cap
and macintosh and left the house. The morning air on Arthur's Seat would
blow the cobwebs from his brain; the scent of the heather, and above
all, the sight of the sea. He roamed over the wet slopes above Holyrood
for a couple of hours, and did not return until the exercise had shaken
some of the horror out of his bones, and given him a ravening appetite
into the bargain.

As he entered he saw that there was another man in the room, standing
against the window with his back to the light. He recognised his
fellow-student Greene, who was reading for the same examination.

"Read hard all night, Marriott," he said, "and thought I'd drop in here
to compare notes and have some breakfast. You're out early?" he added,
by way of a question. Marriott said he had a headache and a walk had
helped it, and Greene nodded and said "Ah!" But when the girl had set
the steaming porridge on the table and gone out again, he went on with
rather a forced tone, "Didn't know you had any friends who drank,
Marriott?"

This was obviously tentative, and Marriott replied drily that he did not
know it either.

"Sounds just as if some chap were 'sleeping it off' in there, doesn't
it, though?" persisted the other, with a nod in the direction of the
bedroom, and looking curiously at his friend. The two men stared
steadily at each other for several seconds, and then Marriott said
earnestly--

"Then you hear it too, thank God!"

"Of course I hear it.
