In all the cases of treason-felony which were tried in Dublin, the informations were sworn before me. I had also to issue warrants for the apprehension of the principal organizers of Confederate clubs, and search-warrants for concealed arms. Such transactions were numerous, and the period was one of very fervid excitement. I am therefore proud of being able to declare that no imputation of partiality, precipitance, or undue severity was preferred or suggested in reference to my magisterial conduct. There were several instances in which I refrained from issuing warrants on the evidence of constables or of private informers; but in all such cases the higher authorities were made acquainted with the peculiar circumstances under which further proceedings appeared to be unnecessary or inadvisable, and approved of the forbearance. If a person was known to have joined a Confederate club, or to have made seditious speeches, or to have subscribed to a fund for the purchase of arms, or to have attended meetings for drilling and training; and if it was also known that he had relinquished such associations and practices, and especially if he was desirous of leaving the country, there was no anxiety to prosecute him or delay his departure. JOHN MITCHELL. The most important case tried in Dublin was that of John Mitchell, for treason-felony, grounded on his publications in _The United Irishman_ newspaper. He had been committed by me, and on the 27th May he was convicted and sentenced to transportation for fourteen years. The only relic of the period in my possession is his "pattern pike," which was found in his house when the police seized the premises. On the day of his condemnation, I was passing along Capel Street on an outside hackney jaunting-car. At Mary's Abbey corner I was recognized by a crowd of roughs, and saluted with a volley of stones. Not one of the missiles struck me, but the carman received a blow on the point of his left elbow which caused intense pain, and elicited copious maledictions. Police were close at hand, and protected me from further aggression. I suggested to the driver that the stone was not intended for him, to which he replied--"It hurt me all the same. Them vagabonds shouldn't throw stones without knowing who they'd hit." INFORMERS.
