Hale, of the Senate, whilst he was willing to protect the abolitionist, expressed himself willing to relax the laws and weaken the protection which is given to the slave property in this district! Mr. Davis, of Massachusetts, held the strange doctrine, that while he would not disturb the rights of the slave-holders, he would not cease to discuss those rights!

But a correspondent of the New York _Tribune_, who probably was an eye-witness, gives the following account of the interview between the committee and Dr. Bailey: Clearing his throat, the leader of the committee stretched forth his hand, and thus addressed Dr. Bailey:
