PLEASE HELP PLEASE HELP A wigwam of weather-stained canvas stood at the base of some irregularly ascending hills. A footpath wound its way gently down the sloping land till it reached the broad river bottom; creeping through the long swamp grasses that bent over it on either side, it came out on the edge of the Missouri.
Here, morning, noon, and evening, my mother came to draw water from the muddy stream for our household use. Always, when my mother started for the river, I stopped my play to run along with her. She was only of medium height. Often she was sad and silent, at which times her full arched lips were compressed into hard and bitter lines, and shadows fell under her black eyes. Then I clung to her hand and begged to know what made the tears fall.
"Hush; my little daughter must never talk about my tears;" and smiling through them, she patted my head and said, "Now let me see how fast you can run to-day." Whereupon I tore away at my highest possible speed, with my long black hair blowing in the breeze.
I was a wild little girl of seven. Loosely clad in a slip of brown buckskin, and light-footed with a pair of soft moccasins on my feet, I was as free as the wind that blew my hair, and no less spirited than a bounding deer. These were my mother's pride,—my wild freedom and overflowing spirits. She taught me no fear save that of intruding myself upon others.
