Dash--dot--dash--dot from the instrument. Tommy ran to the table again.

Dash--dot went back. For five minutes Tommy labored, while the beetles hammered now on one door, now on another, now on the windows. Then Tommy got up.

"It was some station down the line," he said. "I've told them, and they're sending a man up here to replace the telegraphist, also a couple of cops. They think I'm crazy. I told them again. That's the best I could do."

"Dodd! Travers! For the last time--let's talk!"

The cloud of beetles seemed to have thinned, for the sun was shining into the room. Bram's voice was perfectly audible, though he himself was invisible; probably he thought it likely that the defenders had obtained firearms.

"Nothing to say to you, Bram," called Dodd. "We've finished our discussion on the monotremes."

"I want you fellows to stand in with me," came Bram's plaintive tones.

"It's so lonesome all by one's self, Dodd."

"Ah, you're beginning to find that out, are you?" Dodd could not resist answering. "You'll be lonelier yet before you're through."

"Dodd, I didn't bring that swarm up here. I swear it. I've been trying to control them from the beginning. I saw what was coming. I believe I can avert this horror, drive them into the sea or something like that.

Don't make me desperate, Dodd.

"And listen, old man. About those monotremes--sensible men don't quarrel over things like that. Why can't we agree to differ?"

"Ah, now you're talking, Bram," Dodd answered. "Only you're too late.

After what's happened here to-day, we'll have no truck with you. That's final."

"d.a.m.n you," shrieked Bram. "I'll batter down this house. I'll--"

"You'll do nothing, Bram, because you can't," Dodd answered. "Travers has wired full information about your devil-horde, and likewise about you, and all Australia will be prepared to give you a warm reception when you arrive."

"I tell you I'm invincible," Bram screamed. "In three days Australia will be a ruin, a depopulated desert. In a week, all southern Asia, in three weeks Europe, in two months America."

"You've been taking too many of those pellets, Bram," Dodd answered.

"Stand back now! Stand back, wherever you are, or I'll open the door and throw the slops over you."

Bram's screech rose high above the droning of the wings. In another moment the interior of the room had grown as black as night. The rattle of the beetle sh.e.l.ls against the four walls of the house was like the clattering of stage thunder.

All through the darkness Dodd could hear the unhurried clicking of the key.

At last the rattling ceased. The sun shone in again. The ground all around the house was packed with fallen beetles, six feet high, a writhing ma.s.s that creaked and clattered as it strove to disengage itself.

Bram's voice once more: "I'm leaving a guard, Dodd. They'll get you if you try to leave. But they won't eat you. I'm going to have you three sliced into little pieces, the Thousand Deaths of the Chinese. The beetles will eat the parts that are sliced away--and you'll live to watch them. I'll be back with a stick or two of dynamite to-morrow."

"Yeah, but listen, Bram," Dodd sang out. "Listen, you old marsupial tiger. When those pipe dreams clear away, I'm going to build a gallows of beetle-sh.e.l.ls reaching to the moon, to hang you on!"

Bram's screech of madness died away. The strident rasping of the beetles' legs began again. For hours the three heard it; it was not until nightfall that it died away.

Bram had made good his threat, for all around the house, extending as far as they could see, was the host of beetle-guards. To venture out, even with their sh.e.l.ls about them, was clearly a hazardous undertaking.

There was neither food nor water in the place.

"We'll just have to hold out," said Dodd, breaking one of the long periods of silence.

Tommy did not answer; he did not hear him, for he was busy at the key.

Suddenly he leaped to his feet.

"G.o.d, Jimmy," he cried, "that devil's making good his threat! The swarm's in South Australia, destroying every living thing, wiping out whole towns and villages! And they--they believe me now!"

He sank into a chair. For the first time the strain of the awful past seemed to grip him. Haidia came to his side.

"The beetles are finish," she said in her soft voice.

"How d'you know, Haidia?" demanded Dodd.

"The beetles are finish," Haidia repeated quietly, and that was all that Dodd could get out of her. But again the key began to click, and Tommy staggered to the table. Dot--dash--dash--dot. Presently he looked up once more.

"The swarm's halfway to Adelaide," he said. "They want to know if I can help them. Help them!" He burst into hysterical laughter.

Toward evening he came back after an hour at the key. "Line must be broken," he said. "I'm getting nothing."

In the moonlight they could see the huge compound eyes of the beetle guards glittering like enormous diamonds outside. They had not been conscious of thirst during the day, but now, with the coming of the cool night their desire for water became paramount.

"Tommy, there must be water in the station," said Dodd. "I'm going to get a pitcher from the kitchen and risk it, Tommy. Take care of Haidia if--" he added.

But Haidia laid her hand upon his arm. "Do not go, Jimmydodd," she said.

"We can be thirsty to-night, and to-morrow the beetles will be finish."

"How d'you know?" asked Dodd again. But now he realized that Haidia had never learned the significance of an interrogation. She only repeated her statement, and again the two men had to remain content.

The long night pa.s.sed. Outside the many facets of the beetle eyes.

Inside the two men, desperate with anxiety, not for themselves, but for the fate of the world, s.n.a.t.c.hing a few moments' sleep from time to time, then looking up to see those glaring eyes from the silent watchers.

Then dawn came stealing over the desert, and the two shook themselves free from sleep. And now the eyes were gone.

But there was immense activity among the beetles. They were scurrying to and fro, and, as they watched, Dodd and Tommy began to see some significance in their movements.

"Why, they're digging trenches!" Tommy shouted. "That's horrible, Jimmy!

Are they intending to conduct sapping operations against us like engineers, or what?"

Dodd did not reply, and Tommy hardly expected any answer. As the two men, now joined by Haidia, watched, they saw that the beetles were actually digging themselves into the sand.

Within the s.p.a.ce of an hour, by the time the first shafts of sunlight began to stream into the room, there was to be seen only the ma.s.sive, rounded sh.e.l.ls of the monsters as they squatted in the sand.
