Mr. Chauncey M. Depew having been invited to deliver an address in Detroit, Mich., in the interest of Armenia, not being able to attend, wrote a letter to Gen. Alger, the chairman of the meeting, from which we quote as follows: "The air is full just now of wars and rumors of wars. The fighting blood of all the peoples of all civilized countries seems to be warmed to the battle point. But, while there is a great and dangerous excitement over a boundary line in Venezuela and a filibustering expedition in South Africa, the peoples of Europe and of the United States remain unmoved and undisturbed by the burnings, sackings, slaughter and every form of savage murder and lust perpetrated upon the Christians of Armenia simply because of their adherence to the faith of Christendom. I have seen congregations weep at the presentation of the tortures and massacres of Christian martyrs under Nero and Diocletian two thousand years ago. Where are the tears for Christian men tortured and killed, Christian women outraged and slain, Christian children tossed upon the bayonets of a savage soldiery yesterday, last week and last month, with the frightful assurance that they will continue to be slaughtered and outraged and tortured and tossed upon bayonets to-morrow, the day after and next month and for months to come? "Much as I believe in peace and its blessings, much as I detest war and its horrors, much as I feel that great provocations and the most imminent dangers to the liberty or the existence of the territories or the safety of the citizens of the country will justify an appeal to the arbitrament of arms, nevertheless I do feel that by a concert of action of Christian nations, of which the United States should be one, such a presentation should be made to the Sultan and his advisers as would stop these horrors and save our Christian brethren." The case of Rev. Mr. Knapp, of Bitlis, who is to be sent to Constantinople for trial on the charge of sedition, will afford a splendid occasion for a naval display. Let the question be opened up whether these treaty obligations of the Porte mean anything outside the reach of a warship. How can we maintain our traditions as the friend of the oppressed and downtrodden of earth if we let the brutal fanatical Sultan riot still in plunder, lust and blood? Did we care for the poor manacled negro undergoing the horrors of the Middle Passage? Did we have any interest in healing "the open sore of the world?" Did we once have spirit enough to demand of the Bey of Algiers the release of all Christian slaves, the abandonment of the piracy he had practiced for years, and compel him to forego the tribute exacted from all nations? And have we no voice, no heart, no sympathy, no power to demand that the Sultan shall stop his awful carnage of blood and prove before the bar of all Christendom by what right he any longer shall reign?
