A Travelling County Atlas
Another issue of A Travelling County Atlas. See Hall's Map Publisher page. In the top right corner, between the latitude/longitude and the frame there is the number "13". Also top right, but within the latitude/longitude bars, is a new legend: "Railway Stations shown thus", followed by a black line and a small cross bar with the word "Station". There is no explanation for open versus planned railways.
There is a table of Hundreds, with their numbers printed on the map; in this case the individual Hundreds are not coloured, and all roads are uncoloured. The title appears in a rectangular cartouche, with underneath it Engraved by Sidy Hall.
Latitude and longitude (noted as being from Greewich) are inscribed around the border, with 2 minute bars and numbers every 10 minutes. The Northern and Southern Divisions (unnamed) are edge-coloured (although the yellow used for the Southern has almost faded away completely).
Across the bottom is "London. Published by Chapman and Hall, No 193 Strand."
All railways are now shown as black lines, probably overlaying the double parallel black lines with closely spaced cross bars as used earlier. New black lines are shown from Forest Gate to Tilbury and up to Mucking (authorised 1852, opened 1854), and across north Kent (solely as a black line with nothing beneath it). The line of the route from Essex into Suffolk has moved a little, but the "Eastern Counties Rail Road" text has stayed in the same place, so no longer attached to the line. There are now branch lines shown on the routes in Suffolk.
The Romford to the unnamed Thames Haven (authorised 1836 but never built) has been removed, and a (presumably) planned line shown from Mucking to Thames Haven (authorised 1853, opened 1855) by means of the parallel black lines with the ladder in-fill, but with no overlying black line. The routes from Ilford to Ray House, and Layton Stn via Ray House to Epping (not Loughton; authorised 1846, but not built) are also now shown as the open ladder, as is Chapel to Halstead (authorised initially 1846, then in 1856, opened 1860). The Colchester line to Harwich (authorised 1847, opened 1854) is now (correctly) shown branching off at Manningtree.
Displayed scale of 10 miles = 37mm, or 6.9 miles/inch; actual scale = 6. miles/inch, or 1:425,000.
