PLACES LAST BOLT IN FRAME OF 200-INCH TELESCOPE

The final bolt in a spider web of steel that will finally become the mounting for the world’s largest telescope has been turned into place at the turbine plant of the Westinghouse Electric and Manufacturing Company.

Dr. Robert A. Millikan, Nobel prize winner and chairman of the executive council of California Institute of Technology at Pasadena, attended the culminating act of fitting the final part of the mounting, which will have a total weight of 900,000 pounds.
