The story of Mr. Costello was wrung from him very reluctantly. He was subpœnaed on behalf of the State, and confronted with the alternative of being committed for contempt of Court or of being committed for perjury. Mr. Costello, being a revolutionary Irishman, had a morbid horror of doing anything which could in any way lead any one to accuse him, no matter how falsely, of being an informer. The prejudice against the witness-box often appears to be much stronger on the part of Irish Nationalists than the prejudice against the dock. Mr. Augustine E. Costello is an honourable man of the highest character and the purest enthusiasm. He was one of those Irishmen who, loving their country not wisely but too well, crossed the Atlantic for the purpose of righting the wrongs of Ireland. His zeal brought him into collision with the Coercionist Government that was then supreme. He was convicted and sentenced to twelve years’ penal servitude. He was a political offender, the American Government intervened on his behalf, and the treaty known as the Warren and Costello Treaty was negotiated, which led to his liberation before his sentence had expired. During his incarceration in this country he was confined in several prisons, both in England and Ireland, and thus had a fair opportunity of forming a first-hand estimate of the interior of British gaols and the severity of our prison discipline. He was treated, he reported, with a great deal of rigour, but he was never punished without warrant of law, and was never pounded or assaulted. It is characteristic of the Irish political convict that, when Mr. Costello was asked about this before the Lexow Committee, he carefully inquired whether his answers would more or less justify “the people on the other side,” and it was only on being assured that it would do no such thing that he reluctantly admitted that he had never experienced as a convict in British gaols anything like the brutality with which he had been treated by the New York police. Mr. Costello’s story, in brief, is this. About ten or a dozen years ago he was on the staff of the _New York Herald_. By his commission he was attached to the police headquarters, in which capacity he was necessarily brought into the closest relations with captains and inspectors. He discharged his duties with satisfaction to his employers, and without any complaint on the part of the police. Two lawyers of good standing, who were called as witnesses, testified that they had known him for years as a thoroughly honourable man, a newspaper man of talent and ability; one whose word they would take as soon as that of the President of the United States. Every one who knew him spoke in the highest terms of his veracity and scrupulous regard for accuracy.
