The Settlement and Drainage of the Wentlooge Level, Gwent: Excavation and Survey at Rumney Great Wharf 1992
Reproduced with the permission of the publisher and JSTOR. Journal home page http://www.romansociety.org/frame.htmIntroduction: The Wentlooge Level in SE Wales represents an extensive area of some 35 km' of alluvium
reclaimed from estuarine saltmarsh from the Romano-British period onwards (FIGS I-2).1 As
was noted by Allen,' the landscape is characterised at its southern and northern extremities by
a pattern of small irregular fields, often fossilizing the meanderings of natural drainage channels
(FIG. 2). This arrangement is typical of many of the reclaimed alluvial wetlands that fringe the
Severn Estuary.' The remainder of the Wentlooge Level is distinguished by a very different
landscape, comprising regularly planned blocks of long, narrow, and generally straight-sided fields,
quite unique among the wetlands of the Severn Estuary.4 At Rumney Great Wharf, north east of
Cardiff, part of the latter field-system can be seen cut into a clay-peat shelf in the intertidal zone (see
below), thus indicating a major episode of coastal retreat and the repositioning of the sea-wall across
it;s similar evidence from the intertidal zone can be recognised as far to the north-east as Peterstone
Gout.6 An extensive spread of Romano-British pottery and primitive iron-making slag was
associated locally with this field-system in the intertidal zone at Rumney Great Wharf, while survey
of the adjacent mud cliff revealed at least one ditch, sealed by a buried palaeosol, which yielded
stratified Roman material. Further erosion of the mud cliff revealed more ditches with Romano-
British material, as well as other indications of settlement, and prompted a programme of survey and
excavation grant-aided by Cadw and the National Museum of Wales in the spring of 1992

Roman diet and trade: evidence from organic residues on pottery sherds recovered at the Roman town of Calleva Atrebatum (Silchester Hants.)
The analysis of organic residues from pottery sherds using Gas-Chromatography with mass-spectroscopy (GC-MS) has revealed information about the variety of foods eaten and domestic routine at Silchester between the second and fourth–sixth centuries A.D. Two results are discussed in detail: those of a second-century Gauloise-type amphora and a fourth-century SE Dorset black-burnished ware (BB1) cooking pot, which reveal the use of pine pitch on the inner surface of the amphora and the use of animal fats (ruminant adipose fats) and leafy vegetables in cooking at the Roman town of Silchester, Hants

The Metapopulation Dynamics of an Infectious Disease: Tuberculosis in Possums
An SEI metapopulation model is developed for the spread of an infectious agent by migration. The model portrays two age classes on a number of patches connected by migration routes which are used as host animals mature. A feature of this model is that the basic reproduction ratio may be computed directly, using a scheme that separates topography, demography, and epidemiology. We also provide formulas for individual patch basic reproduction numbers and discuss their connection with the basic reproduction ratio for the system. The model is applied to the problem of spatial spread of bovine tuberculosis in a possum population. The temporal dynamics of infection are investigated for some generic networks of migration links, and the basic reproduction ratio is computed—its value is not greatly different from that for a homogeneous model. Three scenarios are considered for the control of bovine tuberculosis in possums where the spatial aspect is shown to be crucial for the design of disease management operation

Silchester Roman Town Insula IX: the development of an urban property c. AD 40-50 - c. AD 250
The development of an urban property in the Roman town of Calleva Atrebatum (Silchester, Hampshire, England) is traced from the late 1st to the mid-3rd century AD. Three successive periods of building with their associated finds of artefacts and biological remains are described and interpreted with provisional reconstructions of the buildings.
