FIRST WELDED PENSTOCK BUILT IN CALIFORNIA
Welding, an abundant source of beautiful photographs, furnishes another picture for the front cover of the Science News Letter this week; but beauty was not sufficient reason for its prominence in the cover position.
The picture was taken within a welded pipe, one-fourth-mile long, tilted up a mountainside at an angle of 45 degrees. It is the penstock, or intake pipe, to Los Angeles’ San Francisquito power plant number 2.
