[Washington (Juno 1) Cor. Chicago Journal.] The Judiciary Committee room was the scène of a most sensational event on the opening of the Blaine investigation this ïnorning. The witness Mulligan, before proceeding with his testimouy, asked to make a statement. He said that, on arriving here, he and Fisher had received a written invitation from Mr. Blaine to cali at his house, but ho declined to go. Fisher went. Blaine then called on him (witness) and begged him not to teil what he knew yesterday. He carne again and made tho same request, asking him to remember his family. He asked to see certain private letters of his (Blaine's), and asked witness what he intended to do with them. Witness told Mr. Blaino he would print them if they tried to break him down, as they were threatening to do. Blaine then begged to be aliowed toread them, and said hewonld return them as soon as read. After reading, ho refused to return them, and had them vet, and witness asked that he might bo obliged by the committee to return them. Mulligan produced a memorandumbook, in which were recorded the transactions between Fisher, Blaine, and various partios in Maine. Mr. Blaine was sworn and said in regard to his interview with Mulligan, that the extravagant words witness attributed to him were fabricated. He did protest strongly against his private letters being printed, and Mulligan liad stated that he intended to make thom public if any one attempted to discredit him or impugn his motives. Mr. Blaine held that witness had no right to those letters, and so he declined to give them back. He had submitted them to two friends, and read them all. With one exception, they did not bear on the subject of the inquiry. He intended to subimt them to two of the best lawyers in Washington, and to be guided by them as to whethor he should produce them. Washington, June 2. On the reassembling of the subJudiciary Committeo to-day, Mr. Hunton, the Chairman, renewed his request to Mr. Blaine to present tho letters taken from Mulligan.

In it Jeremiah S. Black and Matt Oarpenter, as counsel, say they have examined all tho letters, aud tind nothing in them bearing at all upon tho caso now pending before the comiaittoe, and they advise Blaine to assert his right as an American citizen, and resist to the utmost any attempt to take from him any of these private letters.

Mr. Blaine then informed the committee that, in accordance with this legal advico, he would decline to produce tho letters or memorandum of their contents.
