Outings
The National Museums of Scotland Conservation Unit at Granton
An outing has been arranged to the conservation unit of the National Museums of Scotland on Tuesday 31st October starting at 2.00pm.
A wide range of fascinating techniques are used in conservation and are essential in preparing artefacts for presentation and preserving them for future generations. Amongst many other current tasks they are working on preserving a log boat from Carpow and on an 18th century ship found off the west coast of Scotland.
The unit is at Granton on the southern wing of West Granton Road between Granton Square and Crow Road West. It is on the north side of the road to the west of the Lidl store. The unit has its name on the gate but this does not stand out well. Once there, report to security at the entrance and then proceed to the car park.
The staff has gone to considerable trouble to accommodate us so it would be nice if we could have a good turn out.
Lectures
We start again on Wednesday, 18th October but there has had to be a change of speaker. We now have Tam Ward on ‘‘An Unenclosed Platform Site (Bronze Age) at Fruid Reservoir’. As usual lectures are at 7.30pm at 23a Fettes Row. In November (Tuesday, 14th) we have Dr Alex Hale of RCAHMS on ‘An Archaeological Survey of the Pentland Hills Training Area and Ranges’.
Library
New additions include Pat Dennison’s ‘Holyrood and Canongate: A Thousand Years of History’.
Castlehill, Penicuik
During the excavations we have taken six separate soil samples and these will soon be sent for analysis with the hope that they will throw some light on the use of the site in Iron Age times.
The lack of finds associated with domestic occupation possibly endorses the comment, made on the two cobble tools found, that the site could have been used for leather or hide preparation. This is a smelly process that even Iron Age folk would probably be loath to live beside. One other tool, thought originally to be made of pumice, has been termed ‘unconvincing’ by the experts. It seems not to be pumice but is similar in texture and may originate from an unusual geological formation near Carlops. Is it just coincidence that the archaeological reports on leather working sites at Brough of Birsay and the Pictish monastery at Portmahomack state that the excavations have both produced pumice tools or does this tool add to the evidence for leather working at Castlehill?

Dalmeny Estate Mesolithic Dig
The dig took place within the allotted two weeks in a period of very hot weather that made our earlier thoughts of wet sieving unnecessary as the soil was dry to a depth of 0.5m and, when broken up, was generally the consistency of sand.
Some twenty pits were dug, most within the 20 by 20m square L12 which produced the highest number of lithics during field walking in 1997 and 1999.
Two pits, one well to the west and the other to the south, produced virtually no finds suggesting that the Mesolithic activity was probably limited to the raised ground adjacent to the west bank of the River Almond. Most pits produced lithic tools similar to those found during field walking and on the final day, in a pit on the north side of L12, carbonised hazelnut shells were found.
The analysis of the lithics and the shells will take some time but at least the project, which started almost a decade ago, has produced positive results. We will have to await the carbon dating of the hazelnut shells before we know whether the site is a contemporary of that at Cramond at 10K B.P.
Our thanks go to Lord Roseberry and his factor, Mr Jonathan Burrow, for their cooperation and for giving access to the field, and also to Dr Catriona Pickard of the Archaeology Dept of the University of Edinburgh for providing the Mesolithic expertise necessary to supervise the dig.
Ground Resistance Survey at Cousland
On Saturday, 23rd September, we started our first survey in conjunction with David Connolly in East Lothian. Cousland lies on a minor road junction (NT 377 683) to the east of Dalkeith and the archaeological remains are a matter of some debate.
The record in RCAHMS shows a chapel (remains of) near the road junction, a castle (remains of) a little further to the south, then ‘nunnery quarry’ and finally ‘cist with inhumations’. The house on the corner of the road appears to be called Chapeldyke and the castle looks rather like the remains of a tower house and this is what David suggests it is (with some unusual design features – Ed.) There is however a substantial wall, partially collapsed, that runs west from the tower. As it butts on to the tower the assumption is that it is later in date. This wall then continues southwards for over 100m and looks more like a wall that could surround a large formal garden than anything else – so no great support for the suggestion of a cloister for the nunnery. A marked ‘step’ in the field probably indicates that the wall turned to the east at its southern end. If it was a large garden the question is, where is the associated house
The map held by the British Geological Survey, that shows the drift geology of the area, records ‘Bedrock at or near the surface or beneath artificial deposits’. This is borne out by some sections of the tower wall being built on limestone foundations that rise some 0.5m above field level. The whole area has been worked in the past for limestone (and still is); this, plus comments like ‘artificial deposits’ and ‘worked ground’, do not inspire great confidence that ground resistance survey will find anything other than holes that have been dug in the past – or bedrock where they did not dig.

Outings
i) Cammo
We visited this ancient estate south of Cramond on 27th June. It was developed by the eminent horticulturalist, arboriculturalist and agriculturist Sir John Clerk in the late 17th century prior to him inheriting his father’s estate at Penicuik. Many of the features on display in Penicuik were developed here and the estate is of particular interest to those interested in the evolution of estate management in Scotland. Like Mavisbank it has a water feature, but the banks are badly eroded and much work remains to be done to restore it to its former glory. Other features of note were a standing stone, a water tank built as a round tower and the rather spooky ruins of the ‘big house’ burnt down in the last century. We are very grateful to Hamish Bell, the ranger, for the time he spent in making this such an informative and enjoyable afternoon.
ii) Outing to Torphichen and Cairnpapple
We shall be visiting these two particularly interesting monuments in West Lothian on Saturday, 26th August starting at 2.00pm. The first monument, Torphichen Preceptory, was the monastic centre of the Knights of St John, a warrior order that was involved in the care of pilgrims and fighting Saracens in the Holy Land. The tower and transepts of the church and the footings of the priory are still extant. It is a relief to say that it has NO connections with the Holy Grail – so far! We shall then be driving to Cairnpapple, a henge which contains burials that was developed over several millennia. Reconstruction after an excavation means that it provides a particularly vivid impression of its evolution. Visiting involves a short walk up a hill and visitors should wear a stout pair of shoes.
Lectures
We start again on Wednesday, 18th October with Ian Paterson on The Demise of Knossos: A Stratigraphical Problem.
Castlehill, Penicuik
The digging season finished with a final session on 16th July which concentrated on Trench 3 on the inner bank at the SW end of the site. The southern side of this trench contains a lot of sandstone, possibly collapsed or partly robbed out walling of unknown date, but nothing to match the stone packing round a possible post hole which was found on the N side of the trench. A one metre wide section has been cut on this N side down into the ditch between the inner and outer banks. Having reached a fine sandy gravel the thought was that we were down to the natural but, just in case this was downwash from the banks, we went a little deeper. A one by half metre sonde, half a metre deep, appears to have a sandstone paved bottom, but not enough is yet exposed for us to be sure. From the top of the inner bank to the paving we measured a vertical difference of 2.45m; this compares well with the printout from the resistive linear array measurement that was made in 2003 along the line of the N edge of Trench 3, which shows a small rise in resistance under the centre of the ditch. The measurement taken from the linear array print from this resistance to the top of the bank is about 2.5m.
An ever interested and tolerant Sir Robert Clerk has said that we can return for our fifth season in February 2007 so we should be able to find out what is at the bottom of that ditch – in February of course it could be snow. Once again we record our thanks to Sir Robert.
Dalemeny Estate
The guess that the oil seed rape crop might be harvested early was correct and the Farm Manager has given a date of Thursday, 10th August when the field will be clear and available to us. We are likely to work Thursday and Friday, take the weekend off and then work ten consecutive days. The first Thursday is an early start for us as we have to relayout the 20 by 20m grid before the Edinburgh University squad can start to do anything. The square L12, in which the highest concentration of lithics was found, is 60m from our baseline and at the River Almond end of the field so there is a lot of triangulation to do before we dig. Our lithic fieldwalking finds from 1997 and 1999 were assessed by Dr Catriona Pickard and with her particular Mesolithic experience she will supervise the project.
Ground Resistance at Chapelgill Burn
Tam Ward has been excavating at Chapelgill in Glenholm south of Broughton. The site appears to be a late medieval farm – buildings, enclosures and sheep buchts but no main farm building yet. To date four buildings have been investigated. One of these had plastered walls and ceilings, with large ceiling fragments on a floor of packed or puddle clay. A second building had an area of high quality cobbled flooring while a third was a byre with a gruip and well paved floor. Midden deposits have yielded large quantities of glass from wine bottles, medicine phials and window panes. Abundant potsherds and iron objects have also been recovered but none of the artefacts can be dated to earlier than the beginning of the 18th C. although records show that the site was occupied from the 15th C.
Tam’s request to us was to survey an embanked enclosure that lay just up the slope from the excavation sites. The eight 20 by 20m squares surveyed on 22nd July show the bank as a very high resistance suggesting it includes a stone wall. Within the enclosure there are linear high resistances that, in the printout, suggest a group of buildings. After the survey was made, Jill was in West Register House and found an estate map showing farm buildings within the enclosure apparently round a central yard! Trenches have since been cut across the most promising anomalies but no archaeology was found – the very dry ground may have caused problems for the ground resistance measurement.
