transforms the evolutionary races. Meantime the educated and spiritualized children of the surrounding peoples who have been adopted and trained in the prince's schools are returning to their native groups and, to the best of their ability, are there establishing new and potent centers of learning and culture which they carry on according to the plan of the prince's schools.

On Urantia these plans for planetary progress and cultural advancement were well under way, proceeding most satisfactorily, when the whole enterprise was brought to a rather sudden and most inglorious end by Caligastia's adherence to the Lucifer rebellion.

It was one of the most profoundly shocking episodes of this rebellion for me to learn of the callous perfidy of one of my own order of sonship, Caligastia, who, in deliberation and with malice aforethought, systematically perverted the instruction and poisoned the teaching provided in all the Urantia planetary schools in operation at that time. The wreck of these schools was speedy and complete.

Many of the offspring of the ascenders of the Prince's materialized staff remained loyal, deserting the ranks of Caligastia. These loyalists were encouraged by the Melchizedek receivers of Urantia, and in later times their descendants did much to uphold the planetary concepts of truth and righteousness. The work of these loyal evangels helped to prevent the total obliteration of spiritual truth on Urantia. These courageous souls and their descendants kept alive some knowledge of the Father's rule and preserved for the world races the concept of the successive planetary dispensations of the various orders of divine Sons.

The loyal princes of the inhabited worlds are permanently attached to the planets of their original assignment. Paradise Sons and their dispensations may come and go, but a successful Planetary Prince continues on as the ruler of his realm. His work is quite independent of the missions of the higher Sons, being designed to foster the development of planetary civilization.

The progress of civilization is hardly alike on any two planets. The details of the unfoldment of mortal evolution are very different on numerous dissimilar worlds. Notwithstanding these many diversifications of planetary development along physical, intellectual, and social lines, all evolutionary spheres progress in certain well-defined directions.

Under the benign rule of a Planetary Prince, augmented by the Material Sons and punctuated by the periodic missions of the Paradise Sons, the mortal races on an average world of time and space will successively pass through the following seven developmental epochs:

1. The nutrition epoch. The prehuman creatures and the dawn races of primitive man are chiefly concerned with food problems. These evolving beings spend their waking hours either in seeking food or in fighting, offensively or defensively. The food quest is paramount in the minds of these early ancestors of subsequent civilization.

2. The security age. Just as soon as the primitive hunter can spare any time from the search for food, he turns this leisure to augmenting his security.
