seeking part of the name Thomas, and you will find the first three letters Tho, and must hoist CFPD...Tho. Having Tho., the first part of the word required, seek the column headed with the letter M, and look carefully down it till you find mas, the remainder of the word required, for this hoist CDPR...mas. To spell the word Thomas, we first run up CFPD, representing Tho: directly the vessel we are signalling shows her Answering Pennant, the signal CFPD is hauled down, and CDPR, meaning mas, is run up. Then directly the Answering Pennant is seen, CDPR is hauled down, and WVL from the end of the Spelling Table is run up, to signify that the word is finished. MERCATOR'S CHART. A Chart is the representation of the whole or of a part of the surface of the globe. It sometimes happens that the upper part of a chart is not the North. To know the North side, look to a Compass on the Chart and notice the North point of it. The arrow-head or feather at the North point will show the North side of the chart. Then the right hand side is the East; left, West; and bottom, South. The straight lines drawn from North to South are called Meridians. The Meridians divided into degrees and miles are termed Graduated Meridians. The straight lines drawn from East to West are called Parallels of Latitude, or Parallels. The Parallels of Latitude divided into degrees and miles are termed Graduated Parallels. The principal exercises on the Chart are the following: To find the Latitude and Longitude of a given place. To find the ship's position when the Latitude and Longitude are given. To find the ship's position from cross bearings. To find the ship's position from the bearing and distance of a known light or headland. To find the Course and Distance between two given places. To find the ship's position after steering a given Course and distance from a given place. To find the Course to steer to reach a port, when given the set and drift of a current.
