There was a time when our people covered the land as the waves of a wind-ruffled sea cover its shell-paved floor, but that time long since passed away with the greatness of tribes that are now but a mournful memory. 1 will not dwell on, nor mourn over, our untimely decay, nor reproach my paleface brothers with hastening it, as we too may have been somewhat to blame.
Youth is impulsive. When our young men grow angry at some real or imaginary wrong, and disfigure their faces with black paint, it denotes that their hearts are black, and that they are often cruel and relentless, and our old men and old women are unable to restrain them. Thus it has ever been. Thus it was when the white man began to push our forefathers ever westward. But let us hope that the hostilities between us may never return. We would have everything to lose and nothing to gain. Revenge by young men is considered gain, even at the cost of their own lives, but old men who stay at home in times of war, and mothers who have sons to lose, know better.

What does Chief Seattle tell about the condition of his people earlier?
At Denver there was an influx of passengers into the coaches on the eastbound B. & M. express. In one coach there sat a very pretty young woman dressed in elegant taste and surrounded by all the luxurious comforts of an experienced traveler. Among the newcomers were two young men, one of handsome presence with a bold, frank countenance and manner; the other a ruffled, glum-faced person, heavily built and roughly dressed. The two were handcuffed together.
As they passed down the aisle of the coach the only vacant seat offered was a reversed one facing the attractive young woman. Here the linked couple seated themselves. The young woman’s glance fell upon them with a distant, swift disinterest; then with a lovely smile brightening her countenance and a tender pink tingeing her rounded cheeks, she held out a little gray-gloved hand. When she spoke her voice, full, sweet, and deliberate, proclaimed that its owner was accustomed to speak and be heard.
“Well, Mr. Easton, if you will make me speak first, 1 suppose 1 must. Don’t vou ever recognize old friends when you meet them in the West?”
The younger man roused himself sharply at the sound of her voice, seemed to struggle with a slight embarrassment which he threw off instantly, and then clasped her fingers with his left hand.
He slightly raised his right hand, bound at the wrist by the shining “bracelet” to the left one of his companion.

After washing from his hands and face the dust and soil of work, Joe left the kitchen, and went to the little bedroom. A pair of large bright eyes looked up at him from the snowy bed; looked at him tenderly, gratefully, pleadingly. How his heart swelled in his bosom! With what a quicker motion came the heart-beats! Joe sat down, and now, for the first time, examining the thin free carefully under the lamp light, saw that it was an attractive face, and full of a childish sweetness which suffering had not been able to obliterate.
