her most intelligent inhabitants to communicate from one side of the globe to the other through an opening of five hundred miles almost directly through the center of their earth, or more accurately speaking, through the center of gravity.
After forty-five hundred years of experimenting the marvelous feat was accomplished.
Of all the worlds in the constellation of Orion, large or small, Holen is the only one that has succeeded in this astounding feat, although it has been and is being tried on more than a dozen worlds.
This wonderful opening through Holen's center of gravity is lined with sections of ribbed metal which cost the governments fabulous sums. This vast tube was finished thirteen hundred years ago according to our time.
Many lives were sacrificed in the hazardous work of tunneling. Were it not for the ribbed metal which afforded protection with its shelving flanges, the tube could never have been finished.
At the present time the tube is used
