When the law had consummated its crime, and the doom of the felon was pronounced against John Mitchel, there stood in the group that pressed round him in the dock and echoed back the assurances which he flung as a last defiance at his foes, a thoughtful, delicate looking, but resolute young Irishman, whose voice perhaps was not the loudest of those that spoke there, but whose heart throbbed responsively to his words, and for whom the final message of the unconquerable rebel possessed a meaning and significance that gave it the force of a special revelation. "Promise for me, Mitchel," they cried out, but he had no need to join in that request; he had no need to intimate to Mr. Mitchel his willingness to follow out the enterprise which that fearless patriot had so boldly commenced. On the previous day, sitting with the prisoner in his gloomy cell, John Martin of Loughorne had decided on the course which he would take in the event of the suppression of the _United Irishman_ and the transportation of its editor. He would start a successor to that journal, and take the place of his dear friend at the post of danger. It was a noble resolve, deliberately taken, and resolutely and faithfully was it carried out. None can read the history of that act of daring, and of the life of sacrifice by which it has been followed, and not agree with us that while the memories of Tone, of Emmet, and of Russell, are cherished in Ireland, the name of John Martin ought not be forgotten. A few days subsequent to that memorable scene in Greenstreet court-house, John Martin quitted his comfortable home and the green slopes of Loughorne, separated himself from the friends he loved and the relatives who idolized him, and entered on the stormy career of a national leader and journalist, at a time when to advocate the principles of nationality was to incur the ferocious hostility of a government whose thirst for vengeance was only whetted by the transportation of John Mitchel. He knew the danger he was braving; he knew that the path on which he entered led down to suffering and ruin; he stood in the gap from which Mitchel had been hurled, with a full consciousness of the perils of the situation; but unflinchingly and unhesitatingly as the martyr goes to his death, he threw himself into the thinning ranks of the patriot leaders; and when the event that he anticipated arrived, and the prison gates opened to receive him--then, too, in the midst of indignities and privations--he displayed an imperturbable firmness and contempt for physical suffering, that showed how powerless persecution is to subdue the spirit that self-conscious righteousness sustains.
