all the railroads and public buildings, and in the event they were not strong enough to hold all the country, they were to rally around the liberated rebels and their friends at Chicago, Camp Chase, Camp Morton, and other places, after destroying all the public works, railroads, etc., that would be of any service to the Government, in following them up, or baulking their movements. In the meantime, however, the military authorities in Chicago had not been idle, and the rebels and their abettors looked with dismay upon every fresh arrival of troops and artillery, as it was reported in their headquarters by spies, who had the temerity to go to the observatory just opposite the camp, from which they could see almost all over it, and send up hourly reports of everything taking place inside.

On the fourth day of the Convention, the men and officers were paid various sums from twenty to one hundred dollars, and it was left to their option whether they would go to Southern Illinois,
