“What a day we have had, to be sure!” said Dominick as they walked along; “and I’m as hungry as a kangaroo.”

Without noticing the unreasonableness of supposing that long-legged creature to be the hungriest of animals, Otto declared that he was in the same condition, “if not more so.”

On opening the door they were checked by the expression of Pauline’s face, the speaking eyes of which, and the silent mouth, were concentrated into an unmistakable “hush!”—which was emphasised by a significant forefinger.

“What’s wrong?” whispered Dominick, anxiously.

“Sleeping,” murmured Pauline—she was too good a nurse to whisper—pointing to the invalid, who, overcome with the night’s exposure and the morning’s excitement, had fallen into a profound slumber on Otto’s humble couch.

This was a rather severe and unexpected trial to Otto, who had come up to the cave brimming over with camp news for Pauline’s benefit. He felt that it was next to impossible to relate in a whisper all the doings and sayings, comical and otherwise, that he had seen and heard that day. To eat his dinner and say nothing seemed equally impossible. To awaken the wearied sleeper was out of the question. However, there was nothing for it but to address himself to the suppression of his feelings. Probably it was good for him to be thus self-disciplined; certainly it was painful.

He suffered chiefly at the top of the nose—inside behind his eyes—that being the part of the safety-valve where bursts of laughter were checked; and more than once, while engaged in a whispering commentary on the amiable widow Lynch, the convulsions within bade fair to blow the nasal organ off his face altogether. Laughter is catching. Pauline and Dominick, ere long, began to wish that Otto would hold his tongue. At last, some eccentricity of Joe Binney, or his brother, or Mrs Lynch, we forget which, raised the pressure to such a pitch that the safety-valves of all three became ineffective. They all exploded in unison, and poor Marsh was brought to consciousness, surprise, and a sitting posture at the same instant.

“I’m afraid,” he said, rather sheepishly, “that I’ve been sleeping.”

“You have, doctor, and a right good sleep you’ve had,” said Dominick, rising and placing a stool for the invalid. “We ought to apologise for disturbing you; but come, sit down and dine. You must be hungry by this time.”

“Indeed I am. The land air seems to have had a powerful effect on me already.”
