Manhole Explodes

Four engine companies and two ladder trucks from the Cambridge Fire Department responded to an "all out" alarm yesterday afternoon at 4:45 p.m. A short in an underground high-tension line caused a loud explosion which sent a manhole cover smashing against the bottom of a parked car on Dunster St. near the Information Center.

There were no injuries and no apparent damage; numerous fireman, spectators, and reporters went home disappointed.
