Finding the detectives who were in pursuit of the fugitive vigilant and determined in their search, Porterfield became fearful that he could not keep his charge concealed, and so made arrangements to get him into a place of greater security. At this point we meet with a new element amongst the Canada conspirators, viz., the Roman Catholic priesthood. Porterfield had arranged with Father Boucher to take his charge in custody, and keep him concealed. This Father was rector of the parish of St. Liboire, a newly-settled place, about forty-five miles from Montreal--an out-of-the-way place, and so a good place in which to hide him away. The arrangements had been made in advance with this Father to take charge of Surratt, and keep him secreted at his house. He was conveyed there by one Joseph F. Du Tilley, who seems to have been priest Boucher's right hand man. The stratagem to get him away from Montreal was as follows: two carriages drove up in front of Porterfield's house late in the afternoon, when two persons, dressed as nearly as possible alike, went out together; one of these got into one of the carriages, and the other into the other, when they drove away in different directions. Father Boucher appeared at the trial of Surratt as a voluntary witness for the defense, and without any apparent sense of shame convicted himself, by his own testimony, of being an accomplice after the fact. We think that the testimony he gave warrants the conclusion, also, that another priest, Father La Pierre, placed himself in the same category. Both of these Fathers took Surratt into their houses, and kept him concealed,--the first for three, and the latter for two months,--knowing him to be charged with being a conspirator to the assassination of the President of the United States.
