, and on the south by the estuary of the Esk. The area was about ten miles from north to south and three and a half from east to west at its widest part.
[Mack, James Logan (1926). ''The Border Line'', p.85. Oliver & Boyd] Canonbie was the main population centre within the debatable lands.
These lands were finally divided between the English and Scottish crowns by an agreement supposedly arbitrated by the
French ambassador although his line was not ''the last and fynal Lyne of thr particion''.
[Robb, Graham (2018). ''The Debatable Land'', p.138. Picador ] The physical border constructed came to be known as the "Scots' Dike", the "March Dike" or more recently the "Scotsdike plantation", a political border rather than a fortification. The terminal points of the dike were said to be marked by square stones bearing the royal arms of England and Scotland; however, these markers have disappeared, were broken up for building nearby cottages or they never existed in the first place. Spaced along the centre of the bank are a number of small unmarked boundary stones of uncertain date, some of which have fallen.
It has been suggested that the name came from the archaic word "Batable" meaning land which was rich and fertile upon which stock animals were fattened or "battended".
[Robb, Graham (2018). ''The Debatable Land'', p.84. Picador ] This is far from certain, however, and the word appears in 1449 in the expression 'The landez called batable landez or threpe landez in the west marchez', where ''batable'' and ''threpe'' seem to be near-synonyms, and as ''threpe'' means "argument, controversy, dispute" this is perhaps a more likely explanation of "Batable".

Arthuret was a marshy bogland which was difficult to police, with the Scottish jurisdiction having difficulty policing their side from Gretna to
Canonbie. The Debatable Land arose because the
Grahams,
Armstrongs,
Elliots and Bells were too powerful, and the Wardens largely left them alone. These four families raided equally in both England and Scotland, claiming allegiance to neither country; it actually suited both governments to have such a "buffer" zone, so the district became a sort of
no-man’s land, where neither country could or would enforce their jurisdiction.
Eventually the general lawlessness spilled over and both wardens demanded that the Debatable Land be eradicated. So in 1552 the French ambassador was appointed to finalise the border line, together with

, ''Accounts of the Treasurer of Scotland'', 10 (Edinburgh, 1913), p. 212. The method adopted to dig the Scots' Dike was to dig two parallel ditches, and throw the material excavated therefrom into the intervening space, thus forming an earthen mound of varying height. There is no evidence of stone having been used. East of Crawsknow Farm, the Dike appears originally to have been about 12 feet broad and 3 or 4 feet high; however, it is variable e.g. at one point the Dike takes the form of a narrow strip and then becomes a double ditch with a space of about 30 ft separating them. There is little evidence that the dike has ever been used as a footpath. It may be that two teams built the dike, possibly one from each kingdom, with one starting from the west and another from the east. When the teams came close enough to each other they seem to have been about 21 feet out of their bearings and a correction in the line of the Dike became necessary.
[Mack, James Logan (1926). ''The Border Line'', p.94-95. Oliver & Boyd] However, the more prosaic version is that marshy land was avoided, necessitating a curved approach.
Although not a fortification the fields nearby had double hedges planted with thorns and the ditches were wide enough to discourage crossings. The tracks between fields were designed to be "narrow and somewhat crooked so that the enemy or thief might be met at corners and annoyed by crossbow or other means."

Terminal stones

The various sources state that the terminal stones were square stones bearing the royal arms of England and Scotland.

The name "Scots' Dike" was in use by Roy's time, that is the mid 18th-century, but previously "March Dike" seems to have been favoured. It is not clear why the name "Scots" stuck, as the Scots might just as well have called it the "English Dyke": there has been an "Englishtown farm" marked since at least Roy's time.
Place-names associated with the dike
The Blaeu Atlas of Scotland (1654) is the first to indicates a named dwelling, this being "March-dike (dyik)-foot". General Roy's ''Military Survey of Scotland'' undertaken from 17471752, indicates both "Craws Know", "English town" and "Scots Dyke"; however, March-dike-foot is not shown by that name.

(19141918) the section within the Scotsdike Plantation was largely intact, but tree felling operations, such as the laying down of temporary railway lines on top of the dike and the hauling of cut tree trunks, caused considerable damage or even complete destruction in places. The period between 1916 and 1926 seems to have been the worst, despite complaints having been lodged regarding the wholesale destruction of a national monument.[Mack, James Logan (1926). ''The Border Line'', p.97. Oliver & Boyd]
Visual remains
The dike is only traceable within the Scots Dike Plantation, consisting of a bank, with slight ditches on either side, which varies in width from 5.8 m at the west end to 3.3 m at the east end, standing to a maximum height of 0.8 m.[Barber, John (1999).''The Linear Earthworks of Southern Scotland; survey and classification''. Trans. Dumfriesshire & Galloway Nat. Hist. Soc. LXXIII. ISSN 0141-1292. P. 78.] The east and west ends cannot be traced, and in places the ditches have silted up while elsewhere they have been re-cut.

field investigators visited as part of a National survey pilot project. They describe the monument as lying at the centre of a belt of woodland, comprising spruce plantation to the north of the dike and deciduous woodland to its south. Parts of the plantation had been felled recently, but the dense vegetation rendered detailed survey impossible and investigation was limited to surface examination of the dike. The remains of the linear earthwork, between and , consisted mainly of flat-topped bank flanked by a ditch on either side. The form and preservation of these features varied considerably along the length of the dike and it was concluded that little of the monument survived in its original form, but its course is preserved in later boundaries and drainage ditches.
Long sections of the ditches, especially the northern ditch, have been re-cut to provide drainage for the conifer plantation, although in places the modern drainage appears to have been cut through the centre of the dike. Elsewhere, for example at , the feature have been almost plough-levelled, the ditches having disappeared and the bank surviving as little more than a rise in the ground. Between and , where the Glenzier Beck crosses the course of the dike, there are no traces of the earthwork; whether it has simply not survived or whether the dyke was ever constructed across the slack was not apparent. At a number of points along the length of the dike - most notably at approximately and – there is a disjointure in the earthwork which is suggestive of a shift in the line of the original boundary, perhaps due to later land use. At the extreme western end of the dike, between approximately and , a second, much slighter bank and ditch lies to the south of the main earthwork but may be nothing more than later drainage. The course of the dike between the western end of Scotsdike Plantation and the River Sark could not be traced on the ground but it was thought that it followed the extant field boundary to the south of Craw's Knowe farm.
Access
The site is marked as an ancient monument on some tourist maps[Philip's big driver's atlas of Britain. 2007. Octopus Publishing. P. 42.] and 'Solway Heritage' unveiled a new access point to the dike in 1999.[''Dike becomes the Border again.'' Sunday Herald (Glasgow) (11 April 1999) P. 4.] No interpretation or formal access to the dike itself exists at present (2006). The easiest point of informal access is via the minor road at the Sark end of the dike.
Access from the eastern end is from a large lay-by on the A7. A path runs round the back of a house (at ) and up the bank to the rear. On entering the wood there is a bridge across a ditch with a modern marker post showing the location of the boundary.
Status
The Scot's Dike is recorded in the English National Archaeological Record as ancient monument NY37SE 14, and in Scotland it is likewise recorded by the RCAHMS as NMRS number: NY37SE 6. It is a scheduled monument under the terms of the Ancient Monuments and Archaeological Areas Act 1979; from the crest north the monument is scheduled in Scotland; from the crest south, in England.
Scotch Dike railway station
A railway station named Scotch Dyke was opened on 25 October 1861 by the Border Union Railway as 'Scotsdyke' and later renamed 'Scotch Dyke'. It was on the English side of the present border, and closed on 2 May 1949. It was a two-platform station with a level crossing to its north. Today (2006) the former station retains its building and platforms. The canopy of the building has a script reading "Speed and comfort by rail" with its 'British Railways' logo."
Other national border earthworks
The ''Countrup Sike''[ A Researcher's Guide to Local History terminology] at is a much reduced bank, 0.2 m high and 2 m wide, running for less than 20 m, virtually along the line of the border in a north-west direction. Its true nature remains to be confirmed as this will require more than just field observation.

Miscellany
The term 'lands Debatable' was still being used as late as 1604 by the Supreme Courts of Justice in Scotland.[Mack, James Logan (1926). ''The Border Line'', p.91, note 3. Oliver & Boyd]
In Scotland a dyke or ''dike'' is a stone wall, but in England a ''dyke'' is a ditch. In the Cumbrian dialect of English a Dike is the name given to a banked hedgerow.
