"What are you going to do with this stuff?" inquired the pallid-faced man with the stubbly beard, indicating the mass of papers and models. "Oh, we'll leave that here till morning," was Berghoff's response; "dere is no use in taking idt by der boat now." "Goodness," thought Rob, "I sure am in luck! It will be no trick at all to get that stuff as soon as they have gone, and carry it back to the island. I almost wish it was going to be a harder task. It's a bit too much like burglary to suit me." But Rob was not to have such an easy time of it as he anticipated. CHAPTER XIX. A CHASE IN THE NIGHT. The men left the hut, banging the door behind them. Rob waited till the sound of their voices grew dim in the distance, and then raising himself cautiously he crept around to the door of the hut. The light had been extinguished, but as the boy had matches in his waterproof case this fact did not worry him. Pushing the door open Rob entered the place. Before striking a light he did all he could to assure himself that he was not likely to be interrupted by the sudden return of the men. Having established to his satisfaction that he was safe, which was not until he perceived a light on the motor boat, which lay not far from the hut, he proceeded to light up the lantern the men had left behind. Anxious not to lose any time on his risky task, he began stuffing papers and plans into his pockets at once. The models, or most of them, he decided he would have to convey to the boat in his arms. He had hardly completed the task of stowing the papers in his pockets, when he was startled at hearing footsteps coming toward the hut. Hastily he extinguished the light, uttering an inward prayer that it had not been seen. Luckily for himself he had taken the precaution of closing the door as soon as he had the lantern lighted. Just before extinguishing the lamp, he had gazed about the place for some spot of concealment. But the hut, as has been said, was a crude affair, and no closets or cupboards presented a chance of hiding. The only thing that Rob could think of to do was to slip under the table and trust to a miracle that he would not be discovered. Hardly had he carried out his intention when the door opened and two men entered. They were the red-headed man and the pallid-faced individual, who appeared to act as assistants to Berghoff. At any rate, judging by their accents, they were foreigners. Rob had placed the lantern on the table in a position as much resembling that in which the men had left it as he could. He heard a match scratched and then the sputter of the flame. "Don't see why Berghoff sent us back to get that stuff," grumbled one of the men angrily; "it's as safe here as it would be anywhere." "Well, as we're getting good pay fer this job, we might as well obey orders," was the reply. "Gee whillakers!" came a sudden exclamation from the man who had attempted to light the lantern. "What's up?" asked the other.
