Speech at Rushville, Illinois 
He devoted the opening of his speech to the opinions and policy of Henry Clay on the slavery question, showing that his ideas and Clay's coincided, exactly, namely: That in the States where it already exists, it should not be interfered with, but in laying the foundation of societies, in our new Territories, where slavery does not exist, it should not be introduced as an element.
Mr. Lincoln next took up that portion of his Springfield speech, about which so much has been said. As we find about the same ideas involved in his late Alton speech, that he introduced here, we take the liberty to transfer them to our columns as being more satisfactory to our readers.
