ed: either simply in them selues: or
respectiuely, to Hilles, Riuers, Hauens, and Woods adioyning. Some also,
terme this particular description of places, _Topographie_.

"+%Hydrographie%+, deliuereth to our knowledge, on Globe or in Plaine,
the perfect Analogicall description of the Ocean Sea coastes, through
the whole world: or in the chiefe and principall partes thereof:" with
the Iles and chiefe particular places of daungers, conteyned within the
boundes, and Sea coastes described: as, of Quicksandes, Bankes, Pittes,
Rockes, Races, Countertides, Whorlepooles. &c. This, dealeth with the
Element of the water chiefly: as _Geographie_ did principally take the
Element of the Earthes description (with his appertenances) to taske.
And besides thys, _Hydrographie_, requireth a particular Register of
certaine Landmarkes (where markes may be had) from the sea, well hable
to be skried, in what point of the Seacumpase they appeare, and what
apparent forme, Situation, and bignes they haue, in respecte of any
daungerous place in the sea, or nere vnto it, assigned: And in all
Coastes, what Mone, maketh full Sea: and what way, the Tides and Ebbes,
come and go, the _Hydrographer_ ought to recorde. The Soundinges
likewise: and the Chanels wayes: their number, and depthes ordinarily,
at ebbe and flud, ought the _Hydrographer_, by obseruation and diligence
of _Measuring_, to haue certainly knowen. And many other pointes, are
belonging to perfecte _Hydrographie_, and for to make a _Rutter_, by: of
which, I nede not here speake: as of the describing, in any place, vpon
Globe or Plaine, the 32. pointes of the Compase, truely: (wherof,
scarsly foure, in England, haue right knowledge: bycause, the lines
therof, are no straight lines, nor Circles.) Of making due proiection of
a Sphere in plaine. Of the Variacion of the Compas, from true Northe:
And such like matters (of great importance, all) I leaue to speake of,
in this place: bycause, I may seame (al ready) to haue enlarged the
boundes, and duety of an Hydographer, much more, then any man (to this
day) hath noted, or prescribed. Yet am I well hable to proue, all these
thinges, to appertaine, and also to be proper to the Hydrographer. The
chief vse and ende of this Art, is the Art of Nauigation: but it hath
other diuerse vses: euen by them to be enioyed, that neuer lacke sight
of land.
