DEAR SIR: I have the honor to report that on the 19th of November last in accordance with an order from the Secretary of State addressed to yourself, and as I reported to you in full at the time, I tendered through one of my operatives to William J. Walker, a prisoner in the Old Capital Building, the usual oath of allegiance with a view to his taking it and being deischarged from custody. He declined to take such oath for reasons satisfactory to himself (which I reported to you in full at the time), and was left as he was found in prison. Subsequently it sems said Walker singified his willingness to take the oath in the form it had been tendered to him, and in accordance with your orders on the 26th of November the oath was again tendered to him, when he took it and was thereupon discharged from prison. I have the honor to hand you the oath inclosed herewith duly executed to be sent to the Secretary of State in accordance with orders coming from that Department.

Respectfully, your obedient servnat,

E. J. ALLEN.
