In addition also to the blank period in the past, there is the blankperiod in the future. For of the seven sub-races required to completethe history of a great Root Race, five only have so far come intoexistence.

Our own Teutonic or 5th sub-race has already developed manynations, but has not yet run its course, while the 6th and 7thsub-races, who will be developed on the continents of North and SouthAmerica, will have thousands of years of history to give to the world.

In attempting, therefore, to summarize in a few pages informationabout the world's progress during a period which must have occupied atleast as great a stretch of years as that above referred to, it mustbe realized how slight a sketch this must inevitably be.A record of the world's progress during the period of the Fourth orAtlantean Race must embrace the history of many nations, and registerthe rise and fall of many civilizations.
