Thus, it did not establish branches upon other planets until a century or so of experiment had proved that no unforeseen factor would operate to lessen the prodigiously high standard of its products. Nor would it own or operate spaceships, as did other large firms. Its business was the manufacture of the universe's finest, most carefully standardized drugs and it would go into no sidelines whatever.

Even the location of its head office; directly under the guns of Prime Base, bore out the same theme.

It stolidly refused to sell its holdings even to the Galactic Patrol; it would not move until the patrol should condemn its property and compel it by law to vacate.

"All ready," the consultant reported briefly. "Graves is here, you said?"

"Yes. He got in from Deka last night. How long will the demonstration take?"

"Seven hours to the point of maximum yield; twelve for the full life cycle."

"Very good." The vice-president then spoke into the communicator. "Please ask Mr. Graves to step in."
