BREAKING OF A WATER MAIN.

In Boston, Mass., recently, at a point where two iron bridges, with stone

abutments, are being built over the Boston and Albany Railroad tracks at

Brookline Avenue, the main water pipe, which partially supplies the city

with water, had to be raised, and while in that position a large stone

which was being raised slipped upon the pipe and broke it. Immediately a

stream of water fifteen feet high spurted out. Before the water could be

shut off it had made a breach thirty feet long in the main line of track,

so that the entire four tracks, sleepers, and roadbed at that point were

washed completely away.
