Scottish Series 6 1″ Maps

A GENERAL REVIEW OF THE SCOTTISH SERIES 6 ONE INCH MAPS

SCOTLAND

Scottish Series 6 maps were published from Southampton, not Edinburgh They differ from the English and Welsh Series in that they have floating covers and the Lion Rampant on the front cover rather than the full Royal Arms. These arms have “GR” written about them. The numbering is shown on the index map in Red with the England and Wales maps in Black, and the numbering system is unique to the country. 1 to 70 are only Scottish maps but 71 to 92 appear in both series as different maps. Not all Scotland is in the Scottish Series, for example 75 England has Gretna and the region near Dumfries as well as Wigtown

Cumberland (Solway) and these places do not appear on a Scottish map. Scotland No. 75 is much the same region and England 64, that is: Berwick Region. The other maps which cross the border are: Scotland 85, 86, 81; and England 71, 77, 76.

The Isle of Man is in the England Series as number 87.

Scottish maps of the 6th Series use the English Datum of Newlyn LWMMT and they use the National Grid citing 2 figures. Scottish National Grid numbers confirm just how small the island is:  Kirkcudbright is still only 543 km north of a point south of the Scilly Isles.

LANGUAGE

The languages seen in the toponyms of Scotland on Series 6 maps are: Scots, Gaelic, Norn, Old Western Norse, Anglo Norman and Old Welsh.

The map betrays language use by choosing not only the language of the toponym but its spelling “Ben” or “Beinn” might show a defunct language or a living one. It is a country of isoglots and language overlay and theoretically there are two if not three forms of Gaelic toponyms: Pure, or overlaying and absorbing Old Western Norse, Defunct and written in a Scots orthography. Old Welsh survives but is nowhere spoken. It is synonymous withy Pictish and can be seen in “Aberdeen” and other similar names- It is most apparent in the north east of the country. It is the ancestral tongue of the country with Scots (a Germanic tongue) and Gaelic, both arriving in the 6th century.

Small lochs betray language use, particularly when they use the terms Lochan, Lochanan, Lochanain or Loch. Rivers from them- being “River…” or “Abhainn” also show language.

Scottish maps show how languages spread into a landscape- and which are essentially rural, which urban and which maritime. Two Scottish language groups are preserved only in toponyms: Norn and Old Welsh.

GENERAL

There was a hiatus in civilian mapping from 1939-1945.

The Sixth Edition was essentially the Survey of 1930-35 revised for 1945+. A new survey had been planned but its plates were destroyed when the Southampton offices of the OS were bombed- so this 1945+ series returned to a previous set of surveys. The lost survey plates had not been photographically recorded.

It is said that the masters used for Series 6 map were still electrotype engraved for those maps north of Birmingham but the masters were already lithographic for those Series numbers south of that rough line across the English Midlands. The 6th Series itself was entirely lithographic.

The standard dates are 1930 revision -1946 edition

The earliest and latest dates seen are about

1928 revision- 1948 publication.

Some were published in the War : 1940+. These must have had restricted sales

In this series, RAF and RNAS airfield from the 2nd World War are redacted. Royal Dockyards tend to be simply redacted and left white and blank. Army camps tend to be marked because they were visible on pre war maps anyway. Sea Plane stations were redacted.

One might have imagined that post 1945 these could again have been included but it was probably a matter of timing- also, operational RAF and RNAS fields were to remain hidden even onto the Series 7 maps.

RAILWAYS

Scottish railways od this period were dominated by the LM&SR and the L&NER. It was the East Coast L&NER which ran the Flying Scotsman express.

This was the last survey to show the full Pre-British Railways’ network, with the Old Company named written by the lines. The country was covered by the Southern Railway, London & North Eastern Railway, Great Western Railway, and London Midland and Scottish Railways. Some smaller railways remained, notably “Lancashire and Cheshire Lines”, “Midland and Great Northern Joint Railway”, “Norfolk and Suffolk Joint Committee Railway”.

Here was the last survey to definitely show all the branch railways of the district open, prior to the mass closures of the 1950’s- 1960’s.

There were no preservation railways at this age.

ROADS

Series 6 maps named roads with their MOT numbers for the first time on 1 inch maps. This was the last survey to never show Britain motorways.

A roads showed MOT numbers and were red between black base plate lines. B roads had MOT numbers and were orange-yellow between black base plate lines. Other roads were just shown with parallel black lines on the base plate.

LAND USE

Woods are quite a yellow green and symbols show coniferous or deciduous. Orchards had regular tree symbols and are uncoloured. Park land was stippled- perhaps the last remnant of the electrotyped maps of old. Rough Pasture and marshes were shown with a black stippled symbol. Fields were not surveyed. Arable is not differentiated from pasture and a hop garden is not marked as an orchard, but as open land

FORMAT AND STYLE

Series 6 maps tended to be about 27 inches by 31 inches.

Then were sold on cloth or paper. They were not dissected and mounted in sections unless seen as a bespoke preparation for libraries or by cartographic suppliers such as Edward Stanford.

Covers were 8 ¼ inches by 5 inches. Some early ones are shorter and fold the bottom margin in-to accommodate the same sized sheet.

There were 190 maps in the Series, numbered north to south. No 1 was Shetland; No 190 was Truro.

In Series 6 Scottish Maps were still separate from English and Welsh and has different covers- Both were called “1 Inch New Popular Edition” The numbering of the Scottish Series was different. On the index map, printed on the back cover, one sees Scottish sheets numbers in Red 1 to 92 and English and Welsh maps numbered 71 to 190 in black on the Index Map. English series No 64 is an oddity. It showed Berwick. But is remote in numbering from the rest of the English Series. Scottish map 64 was Dundee.

Therefore maps 71 to 92 were found in both Series as different maps. Maps 1-70 were Scottish maps alone and 93-190 were English or Welsh maps alone. The Isle of Man is No. 87 in the English Series.

Paper was not bleached to white and was not gloss. Larger places were names in Roman Serif and smaller places were Italic and capitalised only on their first letters. District or Parish names were an Italic Roman.

There was no shading – either relief of topographic, though close contours form an effective form of relief shading in fell districts. Welsh place names defaulted to the common usage of the region : Afon or River, etc.

NATIONAL GRID

The average map showed 40 km x 45 km or 1800 km squared. This was roughly 25 miles by 30 miles or 600 miles square.

The point 00 or “False Datum” for the National Grid was south west of the Scilly Isles. It thus allowed all Britain to be east or north of that datum. The only exception was Rockall. Ireland was a different survey.

The grid divided the archipelago into 69 100 km squares numbered 1-69. Being asymmetrical, some of these 100 km squares contained no land: 00 ,01, 02, 03, 0-4, 05, 06, 07, 09, 13, 14, 15, 49, 56, 57, 58, 59, 60, 64, 65. 66, 67, 68, 69. Others hardly touched land: 11, 47, 50, 55. Interestingly very few showed no coast water: 43 & 42. Nos 32, 44, 52 showed almost none, and perhaps the only square to show no tidal water was 43.(100 km square No 43- not Map 43).

Some important points on the National Grid were: 500-500: near Flamborough; 199-900, just off Harris; 500-100 near Portsmouth; 200-200 near Pembroke. 400-400: a reasonable Centre of England: inland from Liverpool or Skegness, due north of Poole. Very little of Scotland was east of the E400 line. The E600 is a good approximate for the Greenwich Meridian. London is centred quite near 550-180.

This series was, despite its grid, a “1 inch Series” which was 1/63360. On it One Centimetre represented 0.6336 of a kilometre.

The projection used was a Transverse Mercator. This differs from a Standard Mercator, on which latitude is correct at the Equator, by having two latitudes which are precise- roughly at the tropics and thus the world between those two latitudes is mapped in a compressed manner and the world north and south of them is progressively elongated to the poles. This reduces the distortion and the latitude of the British Isles- which would have been too sever on a Standard Mercator Projection.

ALTITUDE

Altitude was calculated above Mean Sea Level. By this date, that would be from the Newlyn Datum in Cornwall (LWMMT). The old Pre 1915 datum was at Liverpool. Some maps did not fully covert until the 1960’s. The difference between the two data is significant and not standard over the whole of the country. In Kent, for example, it ranged from about 0.9 ft to 1.6 ft. with the Liverpool figure being higher.

Lakes had bathymetric data in feet from water level. So altitude at the bottom would be shore line altitude minus Bathymetric depth. Land lochs have Bathymetric data, Sea lochs have fathoms. Scotland is unique in having many freshwater lochs which plunge well below sea level. Isostatic Rebound must have cause some sea lochs to become freshwater lochs. 100 ft interval contours were surveyed; interim 50ft contours were observed. Contours were umber in colour Series 6 did not revise using Aerial Photography, but the War heralded this form of cartography for Series 7.

COVERS

The cover aesthetic was almost Edwardian and quite unlike that of Series 7 maps. OS did not use gloss covers then.

All editions cited revision and publication dates on the cover.

The covers of Series 6 maps hinged in the English and Welsh series; Scottish maps had floating covers.

HYDROGRAPHY

Series Six maps do not show Admiralty soundings , as earlier terrestrial Ordnance 1” maps did. But the shallows and tidal flats were shown in great detail in a grey stipple- and the major tidal flats are named. The marine contours of a Series 6 map are 5 and 10 fathoms. Note that inland waters are measured in feet not fathoms (if measured at all). A fathom, for safety at sea, was calculated from the lowest tide, not the Mean Tide. Thus you cannot strictly calculate combined terrestrial and submarine altitude by adding on to the other. A fathom is 6 ft so the two contours on a Series 6 OS map equate to 30 ft and 60 ft sea depth. A shallow water which can be measured by plumb line is “sounding”. “Beyond Sounding” is deeper than 100 fathoms. Interestingly, burial at sea has to be at least 6 fathoms: called “Deep Six”. Technically a fathom is 1/1000 of an Imperial Nautical or Sea Mile, which is a little more than 6 ft.

TOWNS

1” OS maps did not show bomb or war damage- there was no new survey work between the Pre war revision date and the publication date. There might have been a couple of exceptions to the above rule, one might have been Portsmouth, where cleared streets seem to be seen near the docks. One has to fine 25” or 50” surveys- used by the Land Registry and Planners before the word “ruin” is seen on buildings, plots and parcels of land.

Urban blocks of buildings were, on Series 6 maps, represented with opaque black. This is the first full lithographic series. Previous editions of the 1” survey used hatching on urban areas, as is necessary with an intaglio, engraved or electrotyped process. The aesthetic result is that this Series 6 seemed bolder, darker and broader lined than that which preceded it. The electrotypes were light, high key and thin lined. This use of black for urban areas was short lived and somewhat problematic. By the 1950’s it had been replaced with lithographic grey in which individual buildings such as town halls and churches could again be differentiated, in black, from the general urban shading.
