He presumes that the outrages and injuries McMaster felt in Ft. La Fayette will incline him to sympathy with those imprisoned in this bastille and to make efforts to bring about their release and to bring notice of their condition to the public. McMaster probably saw in the Dubuque Herald that Meehan was arrested August 14; since that time he has sought a hearing, but has had no answer to his pleas. His arrest was brought about by partisan conspiracy to defeat him for Congress. The Abolitionists were afraid that he would carry the third District of Iowa, if left at large, but they now boast that he is beaten and that the majority is against him. The truth is that he has more followers than before his arrest, although he was not allowed to write one letter in reply to the charges made against him by the Abolition-Republicans. Every effort has been used to suppress his paper and it probably will succumb to the ruling powers. He asks McMaster to print the facts of this political tyranny so that the knowledge of conditions here may be used to defeat the Abolitionists in New York and other states, and to attempt to effect their release. They have learned too much during their imprisonment for their enemies to release them. Although his case is one of peculiar hardship, his family being dependent on sympathetic friends for sustenance, his business ruined, there are other cases of a very aggravating nature. Judge Duff of Southern Illinois was arrested while court was in session. He has written by the same means as he sends this, to Hon. Leonard Wood on the same subject, and he presumes they will confer with each other in an effort to effect their release and the defeat of the Abolitionists. He hopes this will reach McMaster and that it can be of good use for the prisoners and the cause of their country. ` P.S. He need not write to Meehan, but just him a copy of the paper. :: I-1-m A.L.S. 4pp. 12mo.
