Curtis then asked: "Who is your interpreter--one you can trust, one who can read this paper." The two men looked at each other for a moment. Elk said, "Joe?" Two Horns shook his head; then, catching sight of a man who was regarding the scene from a door-way not very distant, he said, in English: "Him--Nawson. Hay, my friend," he called, "come here!" This observer at once responded to Two Horns' sign. As he came up the chief said: "My friend, here is a paper from Washington; read it for us." Curtis said: "I am Captain Curtis, of the cavalry, detailed to act as agent here. This is my commission." The stranger extended his hand. "I'm glad to meet you, Captain Curtis, very glad, indeed." As they shook hands he added: "I've read your articles on the sign language, et cetera, with great pleasure. My name is Lawson." Curtis smiled. "Are you Osborne Lawson? I'm mighty glad to meet you. This is my sister, Mr. Lawson." Mr. Lawson greeted Jennie with grace, and she liked him at once. His manner was direct and his voice pleasing. He was tall, lean, and a little stooping, but strong and brown. "Now, Captain, what can I do for you?" he asked, turning briskly. "I want you to read this paper to the chiefs here, and then I intend to put a guard on the door. Mr. Sennett is not to be permitted to re-enter his office. These are harsh measures, but I am not responsible for them." Lawson looked thoughtful. "I see." After reading the paper he said to the chiefs: "It is as this man has said. The Great Father has sent him here to take charge of the office. The old agent is cut off--he is not allowed to go back to his office for fear he may hide something. Have Crow put a guard on the door. The new agent will try to find out why you have not received your rations. This is the secret of this paper, and here is the signature of the Secretary. This is a true thing, and you must now obey Captain Curtis. I know him," he said, looking round him. "He is my friend; you can trust him. That is all." "Good! Good!" said the chiefs. "We understand." A short, dark Tetong in a frayed captain's uniform came up. "I am chief of the police," he signed. "What shall I do?" "Guard the door of the office and of the issue house. Let no one but those I bring enter. Will you do as I say?" he asked. "Ay!" replied the officer, whose name was Crow. "Then all is said; go guard the door." Sennett and his son had withdrawn a little from the scene and were talking in low voices. They had placed themselves in the worst possible light, and they felt it. As Curtis reached this point in his orders, Sennett started to cross the road. "Wait a moment, gentlemen," called Curtis. "My orders are very strict. I must precede you. There is a certain desk in your library, Mr. Sennett, which I must search." Sennett flamed out into wild oaths. "You shall not search my private papers." "Silence!" called Curtis. "Another oath and I'll put you in the guard-house."
