[At the February term of the U.S. District Court for the Northern District of Illinois, JOHN HOSSACK and JOSEPH STOUT, of Ottawa, were convicted of having aided in rescuing a fugitive slave from the custody of the U.S. Deputy Marshal at Ottawa, Oct. 20, 1859, and sentenced by Judge Drummond to pay a fine of one hundred dollars, and be imprisoned ten days. Mr. HOSSACK is a Scotchman by birth, but spent many years of his life in Quebec, following the occupation of a baker. About twenty years since, he removed to Ottawa, Illinois, and assisted in the construction of the Illinois and Michigan Canal. He has been for some years past a prominent dealer in grain, has acquired a competency by enterprise and industry, and is considered one of the most upright and intelligent citizens in the community. The following Plea, made by him before the Court, evinces true nobility of soul, the highest moral integrity, the most generous humanity, and genuine manly eloquence. Let it be read in every household, so that the execution of the infamous Fugitive Slave Act, in every part of the North, shall be rendered impracticable by a regenerated public sentiment.]
