"Lost! Impossible! Shout, Mr. Dod!"

Dicky shouted, and all the Early Christians answered him. There are said to be seven millions. Mrs. Portheris grasped his arm convulsively.

"Don't do that again," she said, "on any account. Let us go on!"

"Much better not," protested Dicky.

"On! on!" commanded Mrs. Portheris. There was no alternative. We put Dicky in the middle again, and cautiously stepped out. A round of blue paper under our chaperone's arm caught the eye of Mr. Dod. "What luck!" he exclaimed, "you have brought the liqueur with you, Mrs. Portheris. I think we'd better all have some, if you don't mind. I've been in warmer cemeteries."

As she undid the bottle, Mrs. Portheris declared that she already felt the preliminary ache of influenza. She exhorted us to copious draughts, but it was much too nasty for more than a sip, though warming to a degree.

"Better take very little at a time," Dicky suggested, but Mrs. Portheris reaffirmed her faith in the virtues of eucalyptus, and with such majesty as was compatible with the neck of the bottle, drank deeply. Then we stumbled on. Presently Mrs. Portheris yawned widely twice, thrice, and again. "I beg your pardon," said she, "I don't seem able to help it."

"It's the example of these gaping sepulchres," Dicky replied. "Don't apologize."

The passages grew narrower and more complex, the tombs more irregular. We came to one that partly blocked the path, tilted against the main wall like a separate sarcophagus, though it was really part of the solid rock. Looking back, a wall seemed to have risen behind us; it was a distinctly perplexing moment, hard upon the nerves. The tomb was empty, except for a few bones that might have been anything huddled at the bottom, and Mrs. Portheris sat down on the lower end of it. "I really do not feel able to go any further," she said; "the ascent is so perpendicular."

I was going to protest that the place was as level as a street, but Dicky forestalled me. "Eucalyptus," he said soothingly, "often has that effect."
