Syracuse, Sept. 15. - There is a serious break in the Erie Canal near Camillus. Two boats were swept into the breach. One coal boat was broken in two. The berm bank is carried away 100 feet cutting out the bottom of the canal to the depth of 30 feet. The tow-path is also broken some distance. Engineers and a force of laborers are repairing the damage. It will probably require a fortnight for repairs. The escaped water from the canal was safely carried away by the Nine-mile Creek. The breach is at the east side of the Nine -mile-creek aqueduct and difficult to manage.
