Lately he has conducted matters with the greatest secrecy, both for the personal safety of the navigator, and to produce the greater astonishment to those against whom it is designed; and, you may call me a visionary, an enthusiast, or what you please, I do insist upon it that I believe the inspiration of the Almighty has given him understanding for this very purpose and design.”
