But the young student of this heroic training, no matter how well conditioned his family, usually turned from his graduation to some especial mission in life.  “I must put myself into a cause,” said young Wendell Phillips.  Charles Sumner espoused the struggle of the negro for freedom, and said:  “To this cause do I offer all I have.”  Marlowe Mann was a member of the historic Old South Church, like Phillips in his early years.  There was an enthusiasm for missions in the churches of Boston then, and he began to dream of Oregon and the mysterious empire of the great Northwest, as pictured by the old schoolmaster, Kelley; just at this time came Dr. Whitman to the East, half frozen from his long ride, and asked to lead an emigration to Walla Walla, to save the Northern empire to the territory of the States.  He heard the doctor’s thrilling story of how he had unfurled the flag over the open Bible on the crags that looked down on the valleys of the Oregon, and his resolution was made.  He did not follow Dr. Whitman on the first expedition of colonists, but joined him a year or two afterward.  He built him a log-cabin on the Columbia, and gave his whole soul to teaching, missionary work among the Indians, and to bringing emigrants from the East.

The country thrilled him—­its magnificent scenery, the grandeur of the Columbia, the vastness of the territory, and the fertility of the soil.  Here were mountains grander than Olympus, and harbors and water-courses as wonderful as the AEgean.  He was almost afraid to map the truth in his extensive correspondence with the East, lest it should seem so incredible as to defeat his purpose.

When the log school-house was building, Mr. Mann had gone to the old Chief of the Cascades and had invited him to send his Indian boy to the school.  He had shown him what an advantage it would be to the young chief to understand more thoroughly Chinook and English.  He was wise and politic in the matter as well as large-hearted, for he felt that the school might need the friendliness of the old chief, and in no way could it be better secured.

“The world treats you as you treat the world,” he said; “and what you are to the world, the world is to you.  Tell me only what kind of a neighborhood you come from, and I will tell you what kind of a neighborhood you are going to; we all see the world in ourselves.  I will educate the boy, and his father will protect the school.  The Indian heart is hot and revengeful, but it is honest and true.  I intend to be honest with the Indians in all things, and if there should occur a dance of the evil spirits at the Potlatch, no harm will ever come to the log school-house; and I do not believe that such a dance with evil intent to the settlers will ever take place.  Human nature is all one book everywhere.”

As he stood there that morning, with uncovered head, an unexpected event happened.  The children suddenly said:
