It is also folded into four sections of different lengths to fit as the frontis to the Directory. Map has some wear and soiling/staining. This is similar to the large-scale and detailed World chart on Mercator's projection produced by the British Admiralty under the "Superintendence of Captain Wharton R.N. F.R.S Hydrographer" engraved by Edward Weller and sold by J. D. Potter chart agent. The map has no internal landmass detail unless relevant to steam ship routes thus the Suez and Panama canals are marked as is the Canadian Pacific Railway. Panels along the lower edge list major ports and give distances dependent on routes taken and average knots-per-hour speeds with daily distances covered in miles. The world's major ports are linked by ship-routes each track with its relevant distance and so on. An interesting chart at the time steam took over from sail.
