Chinese could not do the work alone. Gilbert was greatly interested in the work of the coolies. Evidently they had to carry their loads to the very heart of the fort, for each was blindfolded[Pg 20] and had to take hold of a rope, the front end of which was in the hands of a Russian sergeant. The sergeant brandished a whip, and if a coolie did not move to suit him, he would give the fellow a cut with the lash. [Pg 20] “This is certainly tough on the Chinamen,” thought the young American. “It’s a wonder they don’t revolt. If they wanted to, they could make matters warm for the Russians.” The coolies having disappeared for the time being, the Russian soldiers came up for their loads. With them were several officers, one of whom eyed Gilbert narrowly. All unconscious of what was taking place, Gilbert drew a little closer to the stores. Then of a sudden he felt a hand on his shoulder. “What are you doing here?” demanded the Russian officer. Gilbert was slightly startled and drew back. But the grip upon his shoulder was not relaxed. “Tell me what you are doing here?” repeated the officer. “Not very much,” was the young American’s answer. “I saw you at the other fort a while ago.” “That is true. I was——” “What are you doing here?” demanded the Russian officer.—Page 20. “What are you doing here?” demanded the Russian officer. “Don’t try to explain here. Come with me. We [Pg 21]allow no spying around here, I can tell you that. You are an American, I believe.” [Pg 21]
