In July 2006, DAACS undertook a two-week survey of slave villages on Nevis in collaboration with archaeologists from DePaul University, the University of Southampton, and National Museums, Liverpool. Goals included locating and initiating preliminary shovel-test-pit surveys of three slave-village sites: Jessups I, Jessups II, and Upper Rawlins. Twenty-seven shovel-test pits were excavated at Jessups I, 16 STPs were dug at Jessups II, and 49 were excavated at Upper Rawlins. Archaeologists also conducted surface inspection at several other slave-village sites on the island.
Archaeologists affiliated with the St. Kitts-Nevis Digital Archaeology Initiative returned to the Jessups’ village sites in 2008 to complete the surveys begun in 2006. A total of 204 shovel test pits and one 1-x-1 meter unit were excavated at Jessups I.
These surveys are part of a larger collaborative fieldwork project in the Caribbean known as The St. Kitts-Nevis Digital Archaeology Initiative. The Jessups villages were selected for a number of reasons. First, a number of evocative primary sources provide glimpses into the development of the Jessups Plantation. These documents include an exceptionally detailed 1755 plat of the property that shows the location of these villages and their movement on the landscape through time as well as a 1748 slave inventory. Please see DAACS document queries for access to images and transcriptions of these documents.
Second, the Jessups village sites are currently under development. Mountainside villas were built along the western edge of the Jessups II village in the early 2000s. Nearly one-third of the Jessups I village was bulldozed in early 2008 to make way for more construction. As a result, portions of each village site were destroyed prior to archaeological investigation.
The St. Kitts-Nevis Digital Archaeology Initiative is funded by a JISC-NEH Transatlantic Digitization Grant to The Digital Archaeological Archive of Comparative Slavery (DAACS), Monticello, The University of Southampton, and the International Slavery Museum, Liverpool. The Jessups villages are a key component of a multiple-year research program in the Caribbean spearheaded by DAACS, known as the DAACS Caribbean Initiative (DCI). DCI’s immediate goal is to document archaeologically through survey, excavation, and collections analysis, the trajectories of change in slave lifeways on the north and south coasts of Jamaica and on the small islands of Nevis and St. Kitts during the 18th and 19th centuries. DCI’s ultimate goal is to improve our understanding of the causal forces that shaped the evolution of slave societies throughout the early-modern Atlantic World by giving researchers access to easily searchable and comparable data from archaeological sites throughout the Atlantic World.
Documentary research on the Jessups estate was conducted by Dr. Roger Leech at the Court House on Nevis as well as at the Southampton Archives Office. The documentary sources for Jessups plantation are principally title deeds and estate records.
The first known document to refer specifically to slavery at the Jessups Estate is a 1748 inventory that includes a list of enslaved individuals owned by Jesup. The inventory provides names and general ages of each individual owned by Jesup. In 1748, Jesup owned 53 men, 29 women, 18 boys, and 11 girls. Another two boys appear to have been in transit to the property, therefore the total slave population was listed as 113 individuals. Several names are embedded with clues to a person’s ethnicity, age, occupation or parentage. In these cases, two names are provided for a single individual, one proper name and one descriptor. For example, the first enslaved man listed is ‘Jack Driver’, suggesting his role as the driver within the village or gang. Two other men were listed with their possible occupations, ‘Mason Cockoe’ and ‘Cooper Cuffee’. Five men carried names that elude to their ethnicity, ‘Mundingo [sic] Prince’, ‘Creole Harry’, ‘Creole Sammy’, ‘Congo Jemmy’, and ‘Congo Scipio’. Four are listed as “old”: ‘Old Man’ ‘Old Jack’, ‘Old Jackoe’, and ‘Old Pompey’.
No women had occupations linked to their names but four carried names suggestive of their origins in Africa. These women included ‘Congo Diana’, ‘Ebo Sarah’, ‘Ebo Jenny’, and ‘Ebo Mary’. ‘Old Sarah’ and ‘Great Kate’ were listed last and were most likely the oldest enslaved women on the property. The 1740 list also provides clues to family groups. Priscilla, Ebo Sarah, Sabine and Judith each had a boy and B Bess, Fanny, and Mary Ann each had one girl. Children’s names such as ‘Little Cuffee’, ‘Little Lucas’, and ‘Little Judith’ may also provide clues to parentage and family structure at Jessups Plantation.
A plat of the Jessups Plantation drawn in 1755 shows in detail where these slaves lived. Titled “A Plan of the Plantation of Edward Jesup, Esq. in the Parish of St. Thomas Lowland in the Island of Nevis”, the plat describes two plantations owned by Jesup, a “Mountain Plantation” and “Lower Plantation”. The Jessups I and Jessups II slave villages were part of Jesup’s “Mountain Plantation” and those living in the villages were engaged primarily in sugar production. Cane fields were planted above and below the great house, mill works, and villages. The plat also shows the location of a cocoa garden, slabs [water collection ponds], pastures, provision grounds, and wooded mountainous zones that climb toward the peak of Mount Nevis.
The most striking feature of the plat is the detailed representation of the “Negro Houses”, an early slave village [Jessups I] northeast of the great house and works, where twenty-two structures of various sizes are arranged across the landscape. A path the leads to the provision grounds winds approximately east/west through the village and a number of the houses appear to face the path. The northern edge of the Jessups I village is bounded by a steep ghut [a narrow passage or gully], through which an intermittent stream flows after rainfall.
Sometime after the completion of the 1755 plat, it was edited to show the location of a second village north of the ghut. At least 13 structures (Jessups II) were lightly penciled in over an area originally designated as a sugar cane field in 1755, suggesting that the early village was moved north of the ghut. Archaeological data from SKNDAI’s 2008 survey has confirmed that the Jessups I village was occupied from the mid-1700s to around 1780 when it was moved to the location of the second village penciled onto the 1755 plat. That village, Jessups II, was occupied after 1780 into the early 19th century.
The history of land transfers among Jesup and subsequent owners and leasees is well documented in deeds and estate records. A 1767 inventory provides details of Jesup’s holdings, including individual slaves, structures, and livestock; however this document has not yet been viewed by DAACS staff.
Excavation history, procedure and methods
The Jessups villages were initially surveyed by Roger Leech in June 2003 at the request of the Nevis Historical and Conservation Society, which was concerned that nearby development had impacted a slave graveyard at Jessups II. Leech conducted a surface survey and mapped several landscape features at Jessups II but did not record cultural features at Jessups I, due in large part to the dense bush covering the majority of Jessups I. Leech identified, but did not map, a path that he associates with the path to the provision grounds shown on the 1755 plat.
2006 Excavation Season
In 2006, using the 1755 plat and visual inspection of the landscape, archaeologists laid-in two east/west transects and one north/south transect. The first east/west transect (STPs 1-20) were placed on 6-meter centers using a total station. The bush was so dense that narrow corridors were cut to allow for total station mapping of pit locations. The distance between pits was occasionally adjusted when physical features such as trees or rock walls prevented their placement on exact 6-meter intervals.
STPs 21-27 were laid-in using a compass and tape on a day when the total station was off-site, thereby explaining the more erratic placement of these pits. Their location was recorded with the total station after excavation.
A total of 27 STPs were excavated at Jessups I in July 2006. However, we encountered nearly undiggable clay throughout the first east/west transect consisting of STPs 1-11. STPs 1-6 were virtually undiggable. We attempted to bring the clay particles into suspension by water screening sediment from these pits but this was a failure. Excavating STPs 7-11 was a bit easier to excavate but the sediment was still barely screenable. STPs 1-6 represent an area of nearly undiggable and virtually unscreenable sediment, with the clay yielding slightly in STPs 7-11, which allowed us to retrieve some artifacts from these pits.
The remaining pits (STPs 12-27) were excavated at 50 centimeters in diameter and, in most cases, were excavated to either subsoil or an apparent sterile layer. All sediment was screened through 1/4-inch mesh. Despite the nearly undiggable conditions along the first east/west transect, a large lump of lead and an 18th-century wine bottle finish were recovered from STP 1.
2008 Excavation Season
Archaeologists with DAACS, the University of Southampton (UK), and the International Slavery Museum (UK), returned to the Jessups I village in July 2008 to complete the STP survey begun in 2006. We discovered that in early 2008 approximately one-third of the remaining early village was cleared and bulldozed in advance of development. The area between the modern cistern and road, where STPs 1-20 were excavated in 2006, had been cleared and graded. A surface survey revealed many sherds of early-to-mid-18th century ceramics, including Afro-Caribbean, White Salt Glaze, and North Midlands Slipware.
The undisturbed portions of the Jessups I village were divided into two survey areas: Areas 1 and 2. Area 1 was north of the recently bulldozed road and Area 2 was east of the modern cistern. Both areas were covered in heavy bush and required extensive clearing prior to excavation.
Two datums were established at Jessups I. We used a total station and GPS to place an UTM grid across the site. All shovel test pits were placed on 6-meter centers using a total station. An alphanumeric system was established for naming STPs that combined the Area, the Transect Letter, and the STP number. Jessups I was divided into two areas, 1 and 2. Transects were labeled alphabetically across the site. STPs were numbered consecutively within each transect. As a result, STP context numbers follow this format: 1-G-01, which translates into Pit 1, on Transect G, in Area 1.
In Area 1, 135 shovel test pits were excavated on 6-meter centers. Forty-one STPs were excavated in Area 2. All STPs were 50 centimeters in diameter and all excavated sediment was screened through 1/4-inch mesh. In most cases, the pits were excavated to subsoil.
A single 1-x-1 meter unit was excavated in Area 2. Excavation of the unit stopped when a large lime/ash/mortar feature was encountered. The edges of the feature extended beyond the unit and excavators initially believed it was a shallow sediment layer before hitting subsoil. However, as they dug into the feature, they encountered a vertically oriented cobble in the middle of the unit that seemed to be firmly buried in another >20 to 30 centimeters of sediment. Excavation was stopped once the cobble was revealed. The feature was photographed and drawn and the unit was backfilled.
Summary of research and analysis
Preliminary results from our analysis of archaeological data recovered in 2008 from the New River, Jessups, and The Spring village sites are outlined here. The analysis is intended only to evaluate the analytical potential of the data and thereby the utility of the field research and digitization design that we have employed. We cannot hope to exhaust that potential here. After all the premise of the project is that the analytical potential of the data can only be realized when they are made freely available on the web to all researchers.
The historical questions that motivate our work at Jessups arise from anthropologist Sidney Mintz’s suggestion that the early-modern Caribbean is usefully understood not as a culture area, but as an ecological community (Mintz 1996). The implication of this idea is that ideological, behavioral, and material variation in time and space is not the outcome of the blending of cultural traditions, but rather the product of cultural strategies invented and adopted by individuals and groups to pursue their conflicting interests in the face of dynamic social, economic, and ecological environments. Artifacts can help us document strategic variation in space and time, and further our understanding of it.
Taking Mintz seriously requires archaeological data that capture variation at multiple spatial scales, within slave villages, among estates, and among islands. The 2008 fieldwork was an attempt to address spatial variation on all three scales by excavating shovel-test pits on 6-meter centers at the slave villages associated with three estates (New River and Jessups on Nevis and The Spring on St Kitts). The spatial analytical potential of the St. Kitts-Nevis project is further enhanced by its being embedded in a larger research framework, The DAACS Caribbean Initiative (DCI). DCI adds the systematic study of sugar estates and their slave villages on Jamaica to the mix, allowing analysis of biogeographic effects on slave lifeways (Terrell 2006). However, spatial variation is analytically intractable unless there is chronological control.
For this reason, the principle focus of our initial analysis is on dating. We show that it is possible to date accurately beginning and ending dates of each settlement and chart change in the intensity and location of occupation within settlements over time. With dates in hand, we then assess the extent to which it is possible to chart change over the course of the village occupations in the frequency of an artifact class that is a major focus of our project: Afro-Caribbean ware.
Our chronology relies on frequency seriation. The seriation method assumes that the relative frequencies of types, in our case ceramic ware types, in a suite of temporally successive assemblages follow lenticular or Gaussian curves. If this is right, then an ordering of undated assemblages in which type frequencies display this pattern is likely to be a chronology (Dunnell 1970). We rely on two complementary methods to estimate order: correspondence analysis (CA) and mean ceramic dates (MCDs) (Ramenofsky, Neiman and Pierce 2009, Smith and Neiman 2007). CA converts a data matrix of type frequencies into a set of scores which estimate the positions of the assemblages on underlying axes or dimension of variation. MCDs are weighted averages of the historically documented manufacturing date for each ware type found in an assemblage, where the weights are the relative frequencies of the types. Measuring the correlation between CA axis scores and MCDs offer an indication of whether the CA scores capture time (Ramenofsky, Neiman and Pierce 2009).
Because artifact samples from individual STPs are small, a large proportion of variation among assemblages is the result of sampling error, which obscures any meaningful pattern. To reduce sampling error, we rely on empirical-Bayes smoothing methods (Robertson 1999). Once the ceramic assemblages from each STP were fit into a single chronological framework, we used regression splines to extract the trajectory of change in AC ware.
As we’ve seen, the location of Jessups’ 18th-century slave village is documented on an 18th-century estate plat, which shows the village adjacent to the great house and mill complex. Penciled addenda on the plat suggest the location of a later settlement, further away from the great house, on the opposite side of a deep ghut. Unfortunately, less than half of the early village site has survived recent road construction in the vicinity. Nevertheless, 204 STPs were excavated at Jessups I, covering roughly a third of the original village site. A total of 93 STPs were excavated at Jessups II, enough to verify that the penciled addenda really do represent later slave housing. However, complete survey of the later village site waits additional funding.
As at the New River Estate, the smoothed ceramic ware-type frequencies fit the expectations of the seriation model well, witness the U-shaped point configuration in the plot of STP assemblages on the first two CA dimensions (Figure 1). The corresponding plot of ware types reveals that CA axis 1 captures time: later types lie on the right and earlier types are on the left (Figure 2). The relationship with time is confirmed in a plot of axis-1 scores against MCDs (Figure 3).
The MCDs suggests that the Jessups I village was occupied from the middle of the 18th century until about 1780. The occupation span for Jessups II apparently runs from about 1780 to 1810. However, the presence of sizable quantities of ceramic wares on the later site that postdate 1820, indicates that the MCD of 1810 may be too early. The discrepancy might be resolved by suggesting that the number of slaves at Jessups II dropped dramatically after 1810. Evaluating this idea requires additional samples from Jessups II.
A comparison of the dating evidence for New River and Jessups reveals that the shifts in the locations of the slave villages occurred at the same time. Not only are the dates the same, but the character of the change was too. In both cases, the site of the old village was terraced for cane cultivation and the new village was located farther away from the great-house and mill complex. The Jessups slave village appears to have moved in order to increase the amount of land under cultivation and bring that production closer to the plantation’s processing hub. This would have increased production efficiency by reducing travel time and labor needed to transport sugar cane to the mill.
We suspect that changes in the frequency of Afro-Caribbean ware may offer evidence for better living conditions for slaves. Here our conclusions are more tentative because research, including INAA and petrographic studies, is ongoing. Afro-Caribbean ware is an open-fired, locally-produced, hand-built ceramic common on slave sites in the Caribbean. Red-slipped exteriors attest to the effort that went into production.
The STP chronologies for New River and Jessups allow us to chart change in the frequency of Afro-Caribbean ware relative to all other ceramics at these sites. Again, statistical methods are critical to defining the pattern of change. We fit a generalized additive model, with logistic link and binomial errors to the New River and Jessups data.
The trend in the relative frequency of Afro-Caribbean ware at the Jessups villages shows similarities and differences with the New River trend. The overall pattern for the course of the occupation is the same: increase followed by decrease (Figure 4). However, at Jessups Afro-Caribbean ware achieves its highest frequency in the late 1760s and there is an apparent dip and then a second increase in the 1770′s. If, as the New River data suggest, AC ware manufacture is largely a Nevisian tradition, this kind of unanticipated variability may track variation in the proportion of newly-arrived Africans, in slave labor forces. These individuals lacked the local knowledge necessary to produce these wares. Again, further work is required to resolve this issue.
We hypothesize that at both villages the increase in Afro-Caribbean ware before 1780 represents increases in the ability of slaves to improve their own lives though local production of ceramics, resulting in the increasingly widespread use of ceramic vessels for food processing, storage and consumption. The post-1800 decline in the proportion of AC ware may represent greater means and motive to acquire and display more costly imported ceramics as living conditions further improved and as payoffs to costly signaling with them increased (e.g. Galle 2010). Further analysis is underway to test this hypothesis.

Things you need to know about the Jessups I Village site before you use the data:
- Field measurements are in meters and centimeters.
- All excavated sediment was passed through 1/4-inch mesh.
- Excavation units and shovel test pits are on the UTM grid system.
- Two hundred four shovel test pits and one 1-x-1 meter unit was excavated at the Jessups I village during excavation seasons in 2006 and 2008.
- In 2008, an alphanumeric system was established for naming STPs that combined the Area, the Transect Letter, and the STP number. Jessups I was divided into two areas, 1 and 2. Transects were labeled alphabetically across the site. STPs were numbered consecutively within each transect. As a result, STP context numbers follow this format: 1-G-01, which translates Area 1, Transect G, Pit 1.
- In the DAACS database, the Jessups I village site is designated as Project “1208″. Artifact ID numbers for artifacts associated with Jessups I therefore begin with the 1208 prefix.
- Architectural and landscape features including terraces, roads, and cisterns, were selectively mapped with a total station. The dense overgrowth in the village made it difficult to map landscape features in a systematic fashion; those represented on the site map are features that could be easily mapped with the total station and limited clearing.
The St. Kitts-Nevis Digital Archaeology Initiative
The archaeological survey of the villages at The Jessups Estate was conducted as part of the St. Kitts-Nevis Digital Archaeology Initiative (SKNDAI). Funded by a JISC-NEH Transatlantic Digitization grant in 2008, The St. Kitts-Nevis Digital Archaeology Initiative (SKNDAI) is an innovative collaborative project designed to further scholarship on slavery. The goal of SKNDAI is to develop an integrated digital archive of diverse archaeological and historical data related to the experiences of the enslaved men and women who labored on 17th-, 18th- and 19th-century sugar plantations in the Caribbean. An international team of scholars from The Digital Archaeological Archive of Comparative Slavery at the Thomas Jefferson Foundation in Charlottesville, Virginia (http://www.daacs.org), the University of Southampton’s Nevis Heritage Project (http://www.arch.soton.ac.uk/Research/Nevis/Nevis.html), and the International Slavery Museum in Liverpool (http://www.liverpoolmuseums.org.uk/ism/) are working together to digitize and deliver on the web information from 18th-century plantations and their slave villages located on Nevis and St. Kitts. The result will be a first-of-its-kind digital collection of fully searchable archaeological and historical data from multiple slave village sites in the Caribbean.
Led by principal investigators Jillian Galle and Fraser Neiman (DAACS, US) and Roger Leech (University of Southampton, UK) and Robert Philpott (National Museums Liverpool/International Slavery Museum, UK), SKNDAI undertook 9 weeks of archaeological survey on three slave villages during the summer of 2008. In addition, Leech worked in archives in Nevis, St. Kitts, and the UK to recover nearly 70 18th- and 19th-century documents related to slavery on these sugar estates. The archaeological and historical data have been digitized and are available through easy-to-use queries on the DAACS website and through the International Museum of Slavery’s website.
Barbara Heath (The University of Tennessee, US), in collaboration with the University of Missouri Research Reactor Center (MURR), conducted instrumental neutron activation analysis (INAA) on Afro-Caribbean ceramic sherds from these sites. Elaine Morris (University of Southampton, UK) has conducted petrographic analysis on the same sherds sampled for INAA. The results will be available through DAACS in early 2011. Joanne Bowen, Steve Atkins, and their team at Colonial Williamsburg’s Zooarchaeological Laboratory analyzed the recovered faunal remains.
The end result of this project acknowledges both scholarly and non-scholarly user-communities by providing free access to information through two web-based portals: the research-oriented DAACS website (http://www.daacs.org) and the publicly-oriented International Slavery Museum website (http://www.liverpoolmuseums.org.uk/ism/).
The work at Jessups was supported jointly by the National Endowment for the Humanities (US) and the Higher Education Funding Council for England of the United Kingdom acting through the Joint Information Systems Committee.
Barbara Heath (University of Tennessee, Knoxville), in collaboration with MURR, is conducting the instrumental neutron activation analysis on the African-Caribbean coarse earthenware ceramics. Elaine Morris (University of Southampton) is conducting the petrographic analysis on these same sherds sampled for INAA. INAA and petrography data will be made available through DAACS artifact queries in early 2011.
Excavations conducted on Nevis and St. Kitts were made possible through the help of many hard working crew members. Lynsey Bates (DAACS/UPenn), Ivor Conolley (DAACS/UWI, Mona), Karen Hutchins (DAACS/UMass), Sara Corker, and Brian McCray (UVA) served as field and lab supervisors for the project.
John Guilbert and Paul Diamond from the Nevis Historical and Conservation Society provided invaluable help and support during our field work on Nevis.
The Reed Foundation, Inc. generously funded three-week internships in historical archaeology for students from the University of the West Indies, Mona, Jamaica. These interns surveyed much of New River I and they included: Krystle Edwards, Suzanne Francis-Brown, Clive Grey, Shailean Hardy, Khadene Harris, and Kenesha King.
University of Southampton students who participated in a four-week archaeology field school were also essential to completing the surveys at New River, Jessups, and The Spring.
There were no archaeological features identified or excavated at the Jessups I village.
DAACS Seriation Method
DAACS staff aims to produce a seriation-based chronology for each site using the same methods (see Neiman, Galle, and Wheeler 2003 for technical details). The majority of sites in the archive are comprised of data derived from deposits within quadrats. On these sites, only assemblages from features or stratigraphic groups with more than five ceramic sherds are included in these ceramic-based seriations. Plowzone contexts do not contribute to a DAACS seriation-based chronology.
The DAACS Caribbean Initiative focuses on exploring large-scale change on slave villages in the Caribbean through the use of shovel-test-pit surveys. For villages with extensive STP coverage, including the Jessups villages, a variation on our site-based seriation method is employed. This is because each STP is small (50 cm. in diameter) and provides a small artifact sample. As a result, STP assemblages are rife with sampling error. The samples from individual STPs are so small that variation among STPs is almost entirely statistical noise.
Successfully analyzing STP data, without first aggregating those pits into counting units called sites, requires methods to suppress sampling error. Here we use empirical-Bayes methods. They offer a smart way to smooth both artifact density surfaces and relative frequencies of artifact types. To understand how these methods work, consider an STP – let’s call it STP 12. The number of artifacts found in STP 12 is likely to be similar to the number of artifacts in the STPs within a certain distance of it. The information contained in the neighborhood of pits is combined with the actual number of artifacts from STP 12 to arrive at an estimate of artifact counts that are less influenced by sampling error (Neiman et al. 2008).
We use two forms of Bayesian smoothing in succession. First, to smooth counts of ceramic ware types in individual STPs, we use a gamma-Poisson model. The gamma-Poisson algorithm smoothes counts of individual artifact types in each STP, based on the counts for that type in nearby STPs. We then use a beta-binomial model to estimate relative frequencies (percentages or proportions) of ceramic ware types in individual STPs. Together two forms of Bayesian smoothing provide smoothed, stable estimates of artifact-type frequency variation in individual STPs, allowing us to see overall site patterning that may otherwise be distorted using raw data (Neiman et al. 2008).
To infer a chronology from the STPs we used correspondence analysis (CA) of ware-type frequencies. We employ CA because with the numbers of STP assemblages in the hundreds, a traditional manual frequency seriation is completely impractical. CA converts a data matrix of ware-type frequencies into a set of scores which estimate the positions of the assemblages on underlying axes or dimension of variation. MCDs are weighted averages of the historically documented manufacturing date for each ware type found in an assemblage, where the weights are the relative frequencies of the types. Measuring the correlation between CA axis scores and MCDs offer an indication of whether the CA scores capture time (Ramenofsky, Neiman and Pierce 2009).
Dating the Jessups I Village
The CA results for Jessups I indicates that there is no temporal trend within the village (Figure 1). However, a village-wide Mean Ceramic Date of 1747 points to the village’s occupation during the mid 1700s.
Two other measures that are less sensitive to excavation errors and taphonomic processes that might introduce a small amount of anomalously late material into an assemblage were used. They are TPQp90 and TPQp95. The TPQp95 of 1762 provides a robust estimate of the site’s TPQ based on the 95th percentile of the beginning manufacturing dates for all the artifacts comprising it. The TPQp90 of 1762 provides a more robust estimate of the site’s TPQ based on the 90th percentile of the beginning manufacturing dates for all the artifacts comprising it.
Bayseian smoothing and CA analysis can be used on STP data from both Jessups I and Jessups II. When data from these village sites are combined in the same analysis, the CA shows clear temporal trends between sites. The smoothed ceramic ware-type frequencies fit the expectations of the seriation model well, witness the U-shaped point configuration in the plot of STP assemblages on the first two CA dimensions (Figure 2).
The corresponding plot of ware types reveals that CA axis 1 captures time: later types lie on the right and earlier types are on the left (Figure 3).
The relationship with time is confirmed in a plot of axis-1 scores against MCDs (Figure 4).
The MCDs suggests that the Jessups I village was occupied from the middle of the 18th century until about 1780. The occupation span forJessups II apparently runs from about 1780 to 1810. However, the presence of sizable quantities of ceramic wares on the later site that postdate 1820 indicates that the MCD of 1810 may be too early. The discrepancy might be resolved by suggesting that the number of slaves at Jessups II dropped dramatically after 1810. Evaluating this idea requires additional samples from Jessups II.

Jessups I Village Harris Matrix
The Harris Matrix summarizes stratigraphic relationships among excavated contexts and groups of contexts that DAACS staff has identified as part of the same stratigraphic group. Stratigraphic groups and contexts are represented as boxes, while lines connecting them represent temporal relationships implied by the site’s stratification, as recorded by the site’s excavators (Harris 1979).
A single 1-by-1 meter unit was excavated at the Jessups I village. The Harris Matrix below is for this single unit (001). It is based on data on stratigraphic relationships recorded among contexts in the DAACS database. It was drawn with the ArchEd application. See http://www.ads.tuwien.ac.at/arched/index.html.
