The Litteral or Roman Figures shew ye Hour of High-Water, or rather ye End of the Stream that setts to ye Eastward, on ye Day of ye New & Full Moon. Add therefore ye time of the Moons Southing or Northing to ye Number found near ye place where your. Ship is, & ye Sun shall show you how long ye Tide will run to ye Eastward. But if it be more than 12 Subtract 12 therefrom. The Direction of ye Darts shew upon what Point of ye Compass ye Strength of ye Tide sets.
