The Hemerdon China Clay Works,Devon: A History and Description of the Site and Working Methods

This article presents an overview of the Hemerdon China Clay Works, 6 miles north-east of Plymouth (Devon), active from c.1860 to 1942. Based on research commissioned in advance of an extension to Headon West Quarry, it describes the development of the clay works and the methods of clay extraction and processing. Archaeological survey recorded a broad range of structures, features, earthworks and artefacts. They included the remains of an engine house of c.1907, two large masonry bases (probably associated with the flat rod system that transferred power from the engine) and a rocker beam. The article also describes a group of mica drags and settling tanks built c.1907. Combining this evidence with that gleaned from documentary sources, notably the large-scale Ordnance Survey mapping, an exceptionally detailed narrative has been constructed of the work's development through time. It has a relevance beyond the particular, and will help the future interpretation and management of the china clay extraction sites that are so characteristic of the region.     

Archaeology of the Border Fort Achiras,Córdoba (1832–1869)

During the nineteenth century, the existence of a southern border in the Córdoba province resulted from a complex situation where an expanding national state was inserted into a global economic system and into an environment occupied by various Indian groups. This situation created a mixed society on the borderlands. The military line was defended by forts, with one of them being the Achiras Fort (1832–1869). The fort was situated at the end of the mountain range of Comechingones. This paper considers the archaeological investigation of this fort. The most important and consistent part of the archaeological record is the Command. The Command was formed by two rooms. This work also presents the results of the excavations into the fort and describes the archaeological remains found. Finally, a general model for archaeology in the South Córdoba Border is presented.     

Excavations at Tilbury Fort,Essex

Tilbury Fort is situated on the N. bank of the Thames 25 miles doumstream from London (TQ 651 754) (FIG. 1). It is the best preserved example of late 17th-century military engineering in England and has been in guardianship since 1950. Plans by the Department of the Environment to alter the visitor access to the site from the riverfront to the landward approach necessitated excavations to establish the original construction of the earthworks, redan and ravelin and to identify the routes and levels of the roadways. Excavations were undertaken in 1973 by Jerry Pratt, concentrating on the ravelin, and in 1980 by the Passmore Edwards Museum. The results of both excavations are presented in this report.     

Pre-Columbian Ring Ditches along the Yacuma and Rapulo Rivers,Beni, Bolivia: A Preliminary Review

Abstract

Pre-Columbian farmers built a variety of earthworks in the Llanos de Mojos, part of the Bolivian Amazon. Raised fields, canals, causeways, and mounds of various types in this region date to ca. 800 B.C.–A.D. 1600. In central Mojos, archaeological work was carried out along the Yacuma, a large west-bank tributary of the Mamoré River. Four ring ditches and two areas of associated raised agricultural fields were mapped. The Global Positioning System was used to document earthworks under the forest canopy which were analyzed within a Geographic Information System. Ceramic evidence is also included. The ring ditches in this study expand the known range of such earthworks in Mojos by 200 km. This revised distribution of ring ditches changes interpretations of the long-term history of Arawak speakers in Mojos and throughout Amazonia. While earthworks in Mojos clearly represent systems of intensive agriculture, they cannot be associated only with Arawak speakers or with Arawak languages.     

New radiometric dates for precolumbian (2000–700 b.p.) earthworks in western Amazonia,Brazil

Abstract

In this paper we present new data on the precolumbian geometric ditched enclosures identified in Acre State, western Amazonia, Brazil. Remote sensing and ground survey have revealed 281 earthworks, located mainly on the edges of high plateaus overlooking the river valleys drained by the southeastern tributaries of the Upper Purus River. Excavations have shown that the few existing cultural materials are concentrated on the slopes and in the bottoms of the ditches, as well as on small mounds that were likely remains of houses, whereas the central, flat enclosed areas lack major archaeological features. New radiocarbon dates place the initial stage of earthwork construction as early as ca. 2000 b.p. We suggest that the building of these geometric earthworks may have been a regionally shared phenomenon, especially among the Arawak and the Tacana peoples, who used them for special gatherings, religious activities, and, in some cases, as village sites.     

Reconstructing Kirkstead Abbey,Lincolnshire: The Charters,Earthworks and Architecture of a Lost Cistercian House

Kirkstead abbey, in the Witham Valley of Lincolnshire, is a little-known but highly significant Cistercian house, both for its early history and architecture, and for the fact that it was treated unusually on being one of the monasteries seized by the Crown for the treason of its president after the Lincolnshire Rising of 1536. Substantially ruined and poorly preserved above ground, recent study has questioned its traditional interpretation. Its standing remains are sparse but extremely informative; its site at least partly marked by earthworks; and its home estate can be reconstructed from a late 13th-century cartulary and a remarkable series of loose charters.     

Some Account of the Parish Church of Bakewell in Derbyshire,and of the Early Grave-Stones and Other Remains Discovered During the Recent Repairs

This report outlines the results of excavations carried out on the Stanwick earthworks in four different areas between 1981–86. At Forcett, area investigation recovered more of the structural plan of the north-western entrance investigated by Wheeler in 1951. Both here and in the Tofts, earlier deposits and features were recognized beneath the ramparts. Wheeler's idea that the Tofts settlement originated as a defended enclosure can no longer be sustained, and geophysical survey has indicated that its southern defences in fact follow a different line from that originally envisaged. Other excavations took place at Henah Hill, where a low bank underlies a long sequence of agricultural activity, itself sealed by the medieval ridge-and-furrow; and at Forcett Barns. The date and context of the earthworks are briefly reviewed in the light of the recent work at Stanwick. The main defensive earthworks were all probably constructed within a relatively short period around the mid first century A.D., when the long-lived settlement was at its most important.     

Natural degradation of earthworks,trenches, walls and moats,Northern Thailand

We here investigate the geometry, age, and history of several enigmatic northern Thailand earthwork entrenchments that are mostly located on hills and could not have held water to form moats. The earthworks are either oval or rectangular in plan view and typically encircle 0.3 to 1?sq km areas with no potsherd debris that would indicate former towns. Most trenches are 3–5?m deep with inner walls 4.5–8?m high. Some encircling earthworks are concentric double trenches spaced approximately 10?m apart. Historians have suggested these earthworks enclosed defensible areas where people in outlying villages sought refuge when under attack by neighboring rulers, the Chinese Ho, or the Burmese. We argue that some encircling entrenchments may have been for the capture or containment of elephants. Nearly all of the once near-vertical original walls have degraded to slopes of 32–47°. Fitting calculated curves of the diffusion-based scarp-degradation model to our height-slope data, and assuming most scarps have degraded since the end of La Na Kingdom time a.d. 1558, we derive a diffusion coefficient of 0.002?m² y^?1. Slopes of the rectangular earthwork at Souvannkhomkham, Laos, across the Mekong River from Chiang Saen Noi, are significantly more degraded (approximately 32°), indicating an age of 800–1200 years. Locations of these earthworks are established in hope that they will be preserved as part of the Thai and Lao archaeological legacy.     

Pre-Columbian human occupation patterns in the eastern plains of the Llanos de Moxos,Bolivian Amazonia

Despite an increasing number of publications regarding the Pre-Columbian earthworks of the Llanos de Moxos, there have been no serious attempts to undertake a systematic survey of the archaeological remains of this lowland region in the Bolivian Amazon. Based on the GIS analysis of data gathered in the field and retrieved from satellite images, we discuss the spatial distribution of the Pre-Columbian settlements in a 4500 Km² area of the Llanos de Moxos to the east of Trinidad, capital of the Beni Department, and their relationship with the geographical settings. Our findings shed new light on the prehistory of the region and bear important implications for our understanding of the impact of Pre-Columbian human occupation.     

Relevance of soil biology and fertility research to archaeological preservation by reburial

Abstract

This paper discusses how soil biological information can help to improve understanding of, and possibly inform decisions about, preservation of organic archaeological remains by reburial. A brief summary of the properties of the soil biological community is followed by an outline of results from recent biological investigations following the recovery of archaeologically relevant materials that had been buried for thirty-three years in one of the experimental earthworks in England UK. Examples from the soil biology and fertility literature are discussed to illustrate the effects of fluctuations in soil wetness and aeration, and of nitrogen availability on decomposition. Finally, the impact of soil handling and physical disruption on biological processes in soil are discussed, as they influence whether soil functions can be restored at a reburial site once the archaeological resources have been ‘protected’ beneath.     

Some Aspects of Byzantine Military Technology from the Sixth to the Tenth Centuries

Abstract

Byzantine military technology remains to be examined thoroughly, despite its importance in demonstrating the Byzantines' ability to absorb ideas and practices from areas outside the Empire as well as developing their own traditions. This article examines arms and armour from the mid-sixth century to the end of the tenth century and puts the military panoply into a wider context, that of the development of offensive and defensive military equipment in Europe and the lands to the north and east of the Empire. Finally, it examines the relationship between military affairs and the economic and political situation of the Empire and attempts to account for the use of particular weapons and methods of equipping the soldiers at particular times.     

An Early Islamic Inter-Settlement Agroecosystem in the Coastal Sand of the Yavneh Dunefield,Israel

This study examines the remains of an agricultural complex found in the Yavneh coastal dunefield, central Israel. Known as a plot-and-berm agroecosystem, the complex consisted of earthworks in a crisscross pattern of sand berms and sunken agricultural plots that were used for groundwater harvesting. The plots, which provided easy access to the high groundwater table and the berms around them, are overlaid by a gray sand unit covered by pottery sherds and artifacts. This gray sand is more fertile than the underlying sand, suggesting refuse enrichment. Artifactual similarity of the finds to those of inland (Tel) Yavneh suggests that Yavneh was the main source for the refuse additive. Based on artifacts and OSL ages it seems that this agroecosystem was active during the 10th to early 12th centuries a.d. The agroecosystem demonstrates an early example of an Early Islamic agrotechnological attempt in marginal and sandy regions of the Mediterranean basin.     

Original DocumentsExtracts from the Pipe Roll of the Exchequer, 21 Edw. III. (A.D. 1353), Relating to the Early use of Guns and Gunpowder in the English Army

This report is concerned with a sampling excavation of Bronze Age, Roman and late Saxon/early medieval settlement traces near the church at Wraysbury, Berkshire. The most extensive evidence is for an agricultural settlement of the late ninth to twelfth centuries A. D. based on a series of ditched enclosures and trackways. The settlement moved location during the eleventh century. The environmental evidence is particularly important. A large faunal assemblage including extensive fish remains exists for the late Saxon and medieval phases as well as an unusual collection of charred plant remains. There are important groups of Late Bronze Age and Saxon pottery.     

Recent British research on prehistoric territorial boundaries

The British Isles are very rich, compared to the rest of Europe, in prehistoric boundary earthworks. There are difficulties in deducing prehistoric territories from them, mainly because of the incompleteness of other evidence of settlement patterns. Fortunately, in the past two decades there have been major advances in territorial studies, in particular, of the pattern defined by the reaves (long walls) on Dartmoor in Southwest England and in the Anglo-Saxon pattern in Southern England defined by boundaries in legal documents (charters). These studies enable some general principles of early land divisions to be deduced, particularly the relations of boundaries to the natural features of the terrain. These principles can be applied to the study of other early boundary earthworks, and, in some cases, reasonable deductions on the nature of the prehistoric estates can be made. The paper concludes with a discussion of major problems, namely, the dating of earthworks, the continuity of boundaries between prehistoric and historic eras, the functions of boundary markers, their chronological development, and their social implications.     

A Statistical Study of Lunar Alignments at the Newark Earthworks

Abstract

Previous work has presented evidence that the Circle-Octagon Earthworks at Newark Ohio contain numerous features that are aligned to the lunar standstills (extreme rise and set points of the Moon). A Monte Carlo study of randomly constructed octagons is presented to investigate the statistical significance of this evidence. The study investigates the sensitivity of the statistics to a variety of plausible assumptions about the design of the earthworks, the capabilities of the builders, and the type and precision of the astronomical alignments. The results of the quantitative study establish that the statistical significance of the evidence for deliberate astronomical alignment over the entire range of plausible assumptions is far too high to be dismissed. The study reveals that the hypothesis of deliberate astronomical alignment predicts the otherwise unexplained shape of both octagonal earthworks constructed by the Hopewell Culture. The analysis compares the Newark dataset to hypothetical datasets which have no statistical significance, so that the difference is clearly established. We also show the evidence is consistent with the hypothesis that the astronomical alignments were established from observations made from high points where the effects of local horizons were negligible.     

Sepulchral Barrows at Broad Down,Near Honiton,and an Unique Cup of Bituminous Shale there Found

The principal characteristics of the earthworks known as pillow mounds—artificial rabbit warrens—are discussed, together with the evidence for their date and purpose. Several aspects of their location and construction have caused considerable confusion to archaeologists in the past, and examples are suggested of current misidentification of these earthworks as prehistoric features. The need for a discussion of pillow mounds has recently become especially urgent due to the recognition of certain types of Neolithic earthwork of similar general appearance.     

Cold War Heritage and the Conservation of Military Remains in Yorkshire 1

Over the last few years there has been a growing interest in the future of military remains created in the UK since 1945. This interest has been sparked by debates that have taken place in archaeology, heritage management and conservation. Our purpose in this article is to intersect with these discussions and practice in a number of ways. First the article sets the discussion of Cold War military sites into the wider context of the rise of military archaeology and heritage conservation more generally. Second, it reviews some of the literature relating to Cold War heritage, both in terms of land management and reuse, but more centrally as a potential national heritage asset. Third, it outlines how this potential asset is managed currently within the heritage protection system and the heritage challenges posed by these remains, particularly the attempts which have been made to incorporate them into a mainstream heritage agenda. Finally, the paper considers the successes and limitations of heritage conservation strategies, under the auspices of the Cold War Monuments Protection Programme (MPP).     

Sheepcotes: Evidence for Medieval Sheepfarming

SHEEPCOTES were late medieval buildings for the shelter of flocks and the storage of fodder, among other functions. They are visible as earthworks and are recorded in documents. This study uses mainly Gloucestershire examples to provide insights into medieval sheep husbandly, and changing patterns of land management.     

A TOWN AT THE CROSSROADS: SITE-WIDE GRADIOMETRY SURVEYING AND MAPPING AT OLD TOWN RIDGE SITE (3CG41) IN NORTHEASTERN ARKANSAS

Abstract

Gradiometry survey at the Old Town Ridge (3CG41) site, a stockaded Middle Mississippian period town in the central Mississippi River Valley of Arkansas, demonstrates the efficacy of a broad-coverage, site-encompassing remote sensing methodology for initial interpretation of intrasite organization and complexity. Site access, time constraints, deep plow furrows, and cotton plant “stubble” associated with ongoing agriculture at the site defer the efficient use of a site-wide multisensor prospection methodology. However, a gradiometry survey identified multiple anomalies consistent with prehistoric structures, earthworks, earthquake liquefaction, and other interpreted features encompassed within the remains of a 7-ha, rectangular enclosure. Aerial photography, topography, and preliminary archaeological ground truthing provided additional information for analysis and interpretation.     

Forced into exile: The untold journeys of Myanmar's CDM teachers

This article delves into the experiences of Myanmar schoolteachers who have fled to Mae Sot, Thailand, as refugees after participating in the civil disobedience movement (CDM) against the military junta's February 2021 coup. The CDM is unique for its large scale and prolonged duration, as well as for its leadership by civil servants, with teachers and educators from the Ministry of Education constituting the majority of protesters. The study analyses the impact of the challenges faced by these teachers, including job loss and legal repercussions, on their understanding of civil disobedience and their commitment to resistance. Through in-depth interviews with 10 CDM schoolteacher refugees in March 2022, the author provides a firsthand account of the experiences and motivations of these individuals.
