Among the publishers who produced charts for the Merchant Navy, "Mount & Page were famous, since the early eighteenth century. In the second half of the century they produced an atlas/pilot book of the Atlantic, from Ireland to Scotland to the islands of Cape Verde. It was entitled The / English Pilot / for the / Southern Navigation / descending the / Sea Coasts, Capes, Headlands, Bays, Roads, Harbours, / Rivers and Ports: / together with the / Soundings, Sands, Rocks, and Dangers / on the / Coasts of England, Scotland, Ireland, Holland, Flanders, / Spain, Portugal, to the Streight's - Mouth; with the / Coasts of Barbary, and off to the Canary, Madeirs, / Cape de Verde and Western Islands. / Shewing the / Courses and Distances from one Place to another; the / Setting of the Tides and Currents; the Ebbing and / Flowing of the Sea, Ec./ London: / Printed for J. Mount, T. Page, and W. Mount, / on Tower - Hill. / M.DCC.LXXVI. (The book is available at the Italian Navy Hydrographic Institute).
The first English Pilot, compiled by John Seller in 1671-72 in two volumes bound in one, each with its own title, published by John Darby, was reprinted in several editions for a few decades. The work was then re-edited by John Thornton in four volumes, in 1703, and had still a remake in 1708 by the publisher Mount & Page - in cooperation with Samuel Thornton, John's son - who published additional improved versions by the end of the century. The pilot book described here (Genoa, Hydrographic Institute of Navy), includes the First Book of 1776, of 92 pages and 25 maps, dated 1778, and the Fourth Book of 66 pages and 25 maps.
On page 5 there are profiles from Dunwich to Blakeney, the Walderswick - Southwould one being particularly significant, which is a coastal view actually conceived as a tiny coastal chart, because of the number of nautical information contained in it: thick bottoms, points of good anchorage marked with a small anchor, and an arrow indicating North.
