In June our pipe was uncovered at several pointsfor examination, and pits about -Jg- of an inch in depth were foundon several pipes. A service pipe of the Hyde Park Water CompanywTas found to be resting upon the 12-inch pipe, making an electriccontact by means of which about 10 amperes of electricity passedfrom the Metropolitan main to the pipes of the Hyde Park WaterCompany.
