In the morning they saddled up and started to go to the Indian camp, but to our surprise Bill and Tom were back at camp by noon, just as Jack and I were getting ready for dinner. "Why, what brought you back so soon?" I asked as they rode up and dismounted. "Well," replied Tom, as they began unsaddling, "we found their camp only about eight miles down the creek--a little closer than I like to have 'em, but the Injuns promised that they wouldn't hunt up this way any farther or do anything to drive off the game in our range; but what brought us back so soon was that when we got there we found ol' To hausen sick in bed, an' I think he's threatened with a severe spell of pneumonia; an' after having a friendly talk with his people and watching the ol' man's symptoms, I made up my mind what was the matter with him, and I concluded that I'd hurry right back to camp and get some medicine for him and then go back and try to fetch the old man out of it.
