The hope of safety from pursuit drives fugitive peoplesinto isolated and barren places that are scarcely accessible orhabitable, and thereby extends the inhabited area of the earthlong before mere pressure of population would have stretchedit to such limits. We find these refugee folk living in pilevillages built over the water, in deserts, in swamps, mangrovethickets, very high mountains, marshy deltas, and remote orbarren islands, all which can be classified as regions of retreat Fugitives try to place between themselves and theirpursuers a barrier of sea or desert or mountains, and in doingthis have themselves surmounted some of the greatest obstaclesto the spread of the human race.
