" At noon I took what is called a noon sight, or meridian altitude of the sun. This established my latitude, or distance north or south of the equator. I used only the sextant with a few figures added and subtracted to come to a hasty accurate computation. In the afternoon-about three-thirty or four- I took a shot of the sun. From its altitude I quickly and easily determined a line of position, at some point on which I was located. Simply by estimating my latitude, according to distance and direction traveled from noon, and applying it to the line, I had my position. Anybody can do it."
