There is not a fowle that appereth, or signe in the aire, or in the sea, which they haue not written, which haue made the voyages heretofore. [Sidenote: The variation of the compasse.] Wherfore, partly by their owne experience, and pondering withall what space the ship was able to make with such a winde, and such direction, and partly by the experience of others, whose books and nauigations they haue, they gesse whereabouts they be, touching degrees of longitude, for of latitude they be alwayes sure: but the greatest and best industry of all is to marke the variation of the needle or compasse, which in the Meridian of the Iland of S.
