It will be remembered that the occasion, if not the cause, of John Brown's raid into Missouri was the solicitation of aid by a slave for himself and companions. Such prayers for succor were not infrequently addressed to abolitionists by those in bonds or by their refugee friends. In the anti-slavery host there were many whose principles wavered not under any test applied to them, and whose impulses urged them upon humanitarian missions, however hemmed in by difficulties and dangers. Among those who heard and answered the cry of the slave were the Rev. Charles T. Torrey, Captain Jonathan Walker, Mrs. Laura S. Haviland, Captain Daniel Drayton, Richard Dillingham, William L. Chaplin and Josiah Henson. The variety of persons represented in this short, incomplete list is interesting: Mr. Torrey was a Congregational clergyman of New England stock, and had been educated at Yale College; Messrs. Walker and Drayton were masters of sailing vessels, and came from the states of Massachusetts and New Jersey respectively; Mrs. Haviland was a Wesleyan Methodist, who founded a school or institute in southeastern Michigan for both white and colored persons; Richard Dillingham was a Quaker school-teacher in Cincinnati, Ohio; William L. Chaplin began his professional life as a lawyer in eastern Massachusetts, but soon became the editor of an anti-slavery newspaper; and Josiah Henson was a fugitive slave, one of the founders of the Dawn Institute in Canada West. With the exception of the last named they were white persons, whose sense of the injustice of slavery caused them to take a stand that shut them out of that conventionally respectable society to which their birth, education and talents would have admitted them.
