FROZEN PIPES.

It. is a well-known fact that a pipe of circular section will hold more than one of elliptical section of tho same external measurement. Hence a lead pipe of the latter form will n<-.t burst in freezing. The water in solidifying Avill change the pipe from elliptical to circular, and ; thus make room for its increased hulk without bursting it. To prevent the bursting of water pipes in* frosts it has been suggested that they should bo made elliptical in section. The drawback to this is that they would only thus stand one freezing, as this woukl ■■reduce them to the ordinary circular form.. In a recent lecture Professor Vivian B. LeAves has suggested that exposed pipes might be slightly flattened with a mallet before a frost. This would serve the same purpose.
