Slowly the equipment took shape within the large hall. The center of construction was the ceramic bath which would hold the mass of protoplasm in its nutrient solution and keep it in controlled temperatures and pressures. The complex observation panel was being assembled beside it. From this point every physiological function of the developing mass could be observed as it progressed. Scores of meters would give electronic readings which could be interpreted in terms of developing functions. It was almost like watching the development and growth of a foetus, for that appeared almost to be the course of growth that was to be expected.
Automatic valves would control the injection into the bath of nutrient materials with an accuracy of a thousandth of a milligram. A dozen operators would be trained, were now being selected, for the precise task of watching the bath during every second of the growth of the organism.
The upper half of the walls of the bath was transparent, as was the cover. Inside, under the cover, the broad reflecting cone of the radiator would spray the long dormant protoplasm with life-giving radiation. Giant generators required to provide this radiation filled other parts of the hall.
It was five months after the actual discovery of the repository that the restoration equipment was completed and tested and ready for use. Public interest in the project had been aroused by the sensational news reports, and a constant stream of people passed the Carlson to glimpse the activities going on inside.
The news stories built up the Stroid as the magnificent benefactor of mankind, as Davis had promised. They presented a sympathetic aspect of a creature imprisoned and doomed throughout the ages, and now being released from bondage and ready to pour out blessings upon his benefactors.
Underwood didn't pay much attention to the news stories, but the increasing swarms of people began to get in his way and hampered operations. He was forced to ask the directors to fence off a large area about the Carlson.
During this time the Lavoisier had been slowly swinging in an orbit about the Earth to keep the repository, taken bodily into its hold, at the temperature of space, until time for the transfer of the protoplasm to the nutrient bath.
Now, with everything completed at the Museum, Underwood and Phyfe returned to the repository to direct the removal of the container of protoplasm, leaving Terry Bernard in charge at the museum. The operators and technicians were ready to take over their duties.
Removal of the protoplasm to Earth was a critical operation. The bath at the Carlson had been brought down to absolute zero and would be brought up a few degrees at a time.
