Note 6 — Group I. THREE RIVAL CIVILIZATIONS.

Drake's Harbor is not satisfactorily identified. Authorities differ. Some, like Admiral Burney, believe the present port of San Francisco to have been Drake's anchorage; others, like Bancroft, maintain this to be wholly improbable, and think Old Port San Francisco, under Point Reyes, was the place. See Fletcher's account, "The World Encompassed," or Bancroft's Monumental History.
