The chiefest vses of the Mariners Carde. Chap. 31. (Book 31)
THe chiefest vses of the sea Card are these foure here following:
The first is to know thereby how that place where∣unto you would sayle, beareth from the place or Port from whence you set off, or depart. And that is to be knowne by the lines of the Mariners Compasses painted in the Card in this manner following: Take a paire of Compasses and hauing ope∣ned them, set the one foote thereof in the very place from whence you depart, and the other foote in the next line of that Compasse which is nearest vnto your place of departing, I meane such line as doth most rightly direct you to the place to which you would go, and your Compasse being opened at the fit widenesse to serue that line, draw them from the place of your departing vnto the place whereto you would go, suffering that foote of the Compasse which standeth vpon the line of the winde whilest you draw it for∣ward, not to swerue one iot from that line, and that line will ey∣ther rightly direct you to the place assigned or fall short thereof, or else ouerrech the same, if it fall short, then take another line nearer to the place from which you departed, and if it ouerreach, take some line that is further off from the place of your depar∣ting,
