Great Molasses Flood
The molasses spread out to other streets. Soon, there was 2-3 feet (up to 1 meter) of molasses on the ground. A police officer was in a signal box talking to his police group when the tank broke.  Because he was already sending a message to other police officers, he called for help right away. Rescue workers came to the North End, but they could not walk or drive carts through the molasses.
