One of these trains belonged to Leopoldo Carillo, a Mexican merchant of Tucson, who paid his men one hundred and fifty dollars for every Indian scalp they delivered to him. Phil asked one of the Mexicans, driving a wagon drawn along by some twelve or sixteen horses, if he had taken any scalps on the trip. The Mexican nodded his head in silence, and turned away. The teamster belonging to the next wagon--an American--told us how the Indians had "jumped them," just after crossing the border, and how two of them had held the Mexican, just spoken to, at bay, while two others killed and scalped his younger brother. They all together, some seven or eight of them, had taken three scalps from the Indians on this trip; but he was willing to lose his share of the prize-money, the man said, if the "pesky devils hadn't taken the boy's scalp;" for the brother, he averred, cried and "took on about it" _just like a white man_. _DOWN AMONG THE DEAD LETTERS._ Strangers visiting Washington, and admiring the style and architecture of the General Post-Office building, would never know that there are numbers of ladies seated behind the plate-glass of the second-story windows. Indeed, few people residing in the capital are really aware in what part of the building those female clerks are stowed away. I had passed on every side of the building--morning, noon, and night--but never had seen anybody that looked like a "female clerk," till I found myself of their number, one morning; and then I discovered the right entrance to the Dead Letter Office. It is on F street, so close to the Ladies' Delivery that any person entering here would be supposed to be inquiring for a letter at that delivery. There is another entrance on E street, but it is not much patronized by the ladies until after fifteen minutes past nine o'clock; for punctually at that time, the door-keeper is instructed to lock the ladies' door on F street, and those who are tardy are compelled to go up the gentlemen's staircase, or pass in at the large public entrance on E street. Crowds of visitors walk through the building, day after day, but not one of all the ladies employed here do they see, unless they request to be shown the rooms of the female _employés_. In this department, working hours are from nine o'clock in the morning till three o'clock in the afternoon. Ladies are not allowed to leave the office for lunch, nor do they waste much time in discussing the lunch they may have brought, as it is only in consideration of their industry and close application that they are allowed to leave the office at three o'clock, instead of four.
