Merrifield's eyes were blazing and his remarks were not dissimilar. "Now, whenever I hold up my hand," he concluded, "you stop still where you are. Understand?" Roosevelt, who would have knocked his ranch-partner down with earnestness and conviction if he had thought Merrifield was in the wrong, meekly bore the hunter's wrath, knowing that Merrifield was in the right; and thereafter on the expedition obeyed orders with a completeness that occasionally had its comic aspects. But Merrifield had no more complaints to make. They plodded on, day after day, seeing no human being. When at last they did come upon a lonely rider, Roosevelt instantly pressed him into service as a mail carrier, and wrote two letters. The first was to his sister Anna. I am writing this on an upturned water-keg, by our canvas-covered wagon, while the men are making tea, and the solemn old ponies are grazing round about me. I am going to trust it to the tender mercies of a stray cowboy whom we have just met, and who may or may not post it when he gets to "Powderville," a delectable log hamlet some seventy miles north of us. We left the Little Missouri a week ago, and have been traveling steadily some twenty or thirty miles a day ever since, through a desolate, barren-looking and yet picturesque country, part of the time rolling prairie and part of the time broken, jagged Bad Lands. We have fared sumptuously, as I have shot a number of prairie chickens, sage hens and ducks, and a couple of fine bucks--besides missing several of the latter that I ought to have killed.
