At an early hour, the temporary building erected for this gathering, near Michigan Avenue, was crowded to excess, and after beginning their labors all the speakers, without exception, entertained the audience and relieved themselves of the most violent denunciations of President Lincoln, and the policy of the administration. Each speaker vied with the last in culling from his vocabulary of hard words, terms sufficiently expressive of their feelings toward the government, but do as well as they might, even with the aid of the poorest quality of whiskey and education, evidently of many years among the lowest of the low, not one of them could out-do the Chicago _Times_. The only parties who could approximate it were Gov. Harris of Maryland, and Long of Ohio, who were most decidedly in favor of secession. The differences between the War Democrats and the Peace men, well nigh ended in personal violence, and would, but for timely interference of the police. It is not our purpose to report the doings of the Convention, and an allusion is only made to call special attention to the elements which made up the party who gave to General George B. McClellan a nomination which proved to him the worst punishment that could have been inflicted, and exhibited him to the world in worse company than he had ever before mingled. The hostility between the different factions of the party, but rendered the Peace wing or Sons of Liberty the more united, and more firmly bent upon the overthrow of the government, as they saw clearly enough, even before the adjournment, that there was not a shadow of hope of electing the ticket formed, and the only hope of genuine copperheads now laid in the election of State officers, and Judge Morris told the people "if we can but get our Governor and Lieut.-Governor, it is all we ask for; the order is strong enough in Illinois, Indiana, Kentucky, Missouri, Iowa and Ohio to enable us to take the general government into our own hands." He added, "as the Washington government had not seen fit to execute the Constitution and the laws, we will bring them to Illinois and execute them ourselves."
