Plumbers Use Alligators To Open Clogged Pipes

“Alligators kept as specimens at the U.S. Bureau of Fisheries aquarium in Washington, D.C, are being tried out as plumber’s assistants to open up clogged pipes. Placed in a length of pipe that is stopped up with silt and sediment, the reptile digs his way through, opening up a small hole which water later will widen by its pressure as it sweeps through.”
