Exploding a Sewer.

Exploding a Sewer.

A contemporary gives the following: The most interesting experiment seen on the beach for a long time was the cleaning out of the York Beach (Me.) sewer pipe recently. The pipe is about ten inches in diameter and runs across the beach just under the surface of the sand and empties into the ocean 150 feet beyond the low water mark. It became stopped up at its mouth and the back pressure burst a hole in it about 200 feet from the end. This hole became the outlet for all the sewerage and the beach was flooded with the foal-smelling water. It was impossible to get to the end of the sewer without hiring a diver, and so it was necessary to clear it out from the break in the pipe. A 150 foot iron rod was procured and a large dynamite cartridge bound securely to its end. Electric wires were fastened to the cartridge and it was then pushed into the break in the pipe. The rod was forced along its entire length, thus pushing the cartridge down the pipe. The wires followed the cartridge in, and when the rod could be pushed no farther the cartridge was exploded by electricity. There was a dull thud which seemed to shake all the earth, and the next instant hundreds of tons of water, sand and rocks were hurled frem the bottom of the ocean. Then the whole mass fell back with a mighty splash, and the water ran through the sewer pipe as freely as could be wished. The explosion blew the whole end off the pipe and of course cleared away every obstruction.
