Harvard men who ran from house to house yesterday afternoon in search of a bathtub they could put a ring around were disappointed to find that the shutdown in the water supply around the Square was complete, affecting the entire University area.

Source of the drought was a break reported one o'clock yesterday morning in the sixteen inch main on Lakeview Avenue in North Cambridge. With a crew from the Cambridge water department working steadily since its discovery, the rent had not been patched last night and it was not anticipated that service would be restored through the main until some time this evening.

Boston's water supply had been tapped in the meanwhile to provision the city of Cambridge, more than half of which found dry faucets over the weekend.

Hardest hit by the calamity were people who, finding their taps supplied only the merest trickle, left the faucet open only to be inundated when Boston water was diverted into Cambridge. Or maybe it was the people who lived downstairs from them.
