“You watch a moment, now,” said Ermi to McEwen, and then hurried down a long passage through which he soon returned bringing with him a sentinel, who took up guard duty at the point where the fight had occurred. “He will stay here and give the alarm in case another attack is made,” he commented. “Come now,” he added, touching McEwen affectionately with his antennæ. Leading the way, Ermi took him along a long winding corridor with which, somehow, he seemed to be familiar, and through various secret passages into the colony house. “You see,” he said to McEwen familiarly, as they went, “they could not have gotten in here, even if they had killed me, without knowing the way. Our passageways are too intricate. But it is as well to keep a picket there, now that they are about. Where have you been? You do not belong to our colony, do you?” McEwen related his experiences since their meeting in the desert, without explaining where he came from. He knew that he was a member of some other colony of this same tribe without being sure of which one. A strange feeling of wandering confusion possessed him, as though he had been injured in some way, somewhere, and was lost for the moment. “Well, you might as well stay with us, now,” said Ermi. “Are you hungry?” “Very,” said McEwen. “Then we will eat at once.” McEwen now gazed upon a domed chamber of vast proportions, with which, also, he seemed familiar, an old inhabitant of one such, no less. It had several doors that opened out into galleries, and corridors leading to other chambers and store rooms, a home for thousands. Many members of this allied family now hurried to meet them, all genially enough. “You have had an encounter with them?” asked several at once. “Nothing to speak of,” said Ermi, who, fighter that he was, had also a touch of vanity. “Look after my friend here, who has saved my life.” “Not I!” cried McEwen warmly. They could not explain, however, before they were seized by their admirers and carried into a chamber where none of the din of preparation penetrated, and where was a carpet of soft grass threads upon which they might lie. Injured though they were, neither could endure lying still for long, and were soon poking about, though unable to do anything. McEwen was privileged to idle and listlessly watch an attack on one portal of the cave which lasted an entire day, resulting in failure for the invaders. It was a rather broken affair, the principal excitement occurring about the barricaded portals and secret exits at the end of the long corridors, where McEwen often found himself in the way. The story of his prowess had been well told by Ermi, and he was a friend and hero whom many served. A sort of ambulance service was established which not only looked to the bringing in of the injured, but also to the removal of the dead. A graveyard was prepared just outside one of the secret entrances, far from the scene of the siege, and here the dead were laid in orderly rows.
