At the period this relic discovery indicates, the proximate swiftness of the current stream setting to and from the Strait of Gibraltar to the La Plata estuary can be estimated by present calculation, which has been rated at twenty miles an hour during the height of a monsoon gale. This would give a surface speed to a floating object of four or five miles an hour, under direct impetus; and with a due allowance for counter slips from eddies, lack of direction, and other causes, a chance voyage might be accomplished in from twenty to thirty days. With the square sails used in Ptolomic vessels, with shallow prows made to imitate the breasts and necks of water fowls, a swift passage could have been made with intention and a favoring wind; but it was the superstitious custom of the ancient mariners to rely upon the direction of fate. M. Hollydorf or Dr. Baāhar could arrive at a proximate conjecture of the derivative source of the Kyronese from the Syriac root and terminals, and by like tests, if of Beberi or Morisco extraction. The fourth wonder of your Arabian Knights’ discoveries is the fact that a savage of the wild hordes can be favorably influenced by exampled goodness, or in any way hold himself amenable to either reason or kindness. Yet I would urge the necessity of impressing them with a knowledge of good and evil, with a detective perception sufficient for your protection against their revengeful instincts, that you may not become the victims of misplaced confidence for the malicious injuries inflicted by our race.
