DISTRICT COURT OF THE U.S. FOR THE DISTRICT OF DELAWARE.- This Court has been in session for nearly a week at New Castle. John Hunn and Thomas Garrett have been fined, the former $2,500 and the lattter $5,400 upon conviction, for aiding slaves to escape from Maryland. There is great dissatisfaction here, and there is a general belief that foul play or corruption has been rife to bring such a result. Messrs. Hunn and Garrett are Quakers of exemplary life and character, and although they would feed the hungry, whether the skin was white or black, yet they would not violate the laws knowingly. The public mind seems bound in investigating this strange affair. A public meeting is talked of- some of the jury are said to be dealers in negroes, in some form. Our Marshal is very much censured. We shall if we can get it publish a history of this transaction. If slavery is permitted to ruin and oppress our best citizens, it is time something was done to remedy the evil.
