Pula: Botswana Journal of African Studies vol. 15 no. 1 An archaeological survey of Ntsweng in Molepolole Princess Sekgarametso Ntsweng was the capital of Bakwena before they moved to Molepolole. The bulldozing of a pan of Ntsweng for a sports field in 1994 inspired the mapping of the site. At Ntsweng, several clusters of ruins seem to represent different wards. Analyses of the settlement layout and soil samples suggest cattle were often kept in the center of each ward. This seems to follow the "central cattle pattern ", a conceptual model for the organization of settlements among southern Bantu, where the central placement of the kraal reflects the central role of cattle in the culture and ideology of the people. Ntsweng is a historic site located a few kilometers southeast of Molepolole in Kweneng District (Fig. 1). The area was first occupied by Bakwena, led by Sechele I, in 1864. It was abandoned in 1937 when Bakwena were forced to move to Molepolole by Kgari II, assisted by the colonial administrators (Schapera, 1943). Ntsweng is one of Botswana's most important monuments. Contrary to the 1970 National Monuments and Relics Act, 24,000 sq m of the site were bulldozed in February 1994 to make a sports field for Sedumedi Community Junior Secondary School. A rescue project was carried out by the Archaeology Unit of the University of Botswana, with assistance from students of Sedumedi Community Junior Secondary School and Legae Academy, to salvage the damaged area. A lot of artifacts like bones, pottery, ostrich eggshell beads, metal earrings and other metal objects were recovered from the area (Borgesen et al., 1994). The inadequacy of cultural resource management in Botswana can be partially blamed for the bulldozing of Ntsweng, as it failed to provide proper delimitation of the site (Borgesen et ai" 1994). This inadequacy in cultural resource management extends even to archaeological sites in Dimawe, Manyana, Lose, Modipe and Domboshaba which have also been damaged. The importance of these sites is that historically written information about Botswana's distant past is very limited. Information mostly comes from archaeological sites which need to be protected, Even though Ntsweng is documented historically, there is still more to the site which needs to be exploited archaeologically in order to add to historical information. If these sites are not preserved, historical information would be lost and we would have no history to talk about. Ntsweng today consists of a large area covered with traces of occupation. Most notable are the patterns of stones laid on their edges to form house foundations which are still visible on the surface. The only building still standing is what used to be Sebele II's office which is at present referred to as Mmakgosi' shouse, The main aim of this paper is to investigate the organization of the settlement at Ntsweng. This was done by conducting an archaeological survey of the remains of structures at Ntsweng. In particular, the survey was to assess the damage done by the bulldozer and to reconstruct the damaged area. Information generated from the survey is used to observe the settlement pattern and the site's functional and symbolic layout. The plan produced is also checked to see whether it conforms to Huffman's central cattle pattern, a characteristic of southern Bantu settlements where cattle have a central place (Huffman, 1986). The results of this survey can be used to guide subsequent archaeological research, as what lies on the site's surface is often a general reflection of what exists beneath. Excavators can use this surface information to place key excavation units so as to test the 23 hypotheses generated from surface data (Knudson. 1978). In this paper. I aim to address three issues. I intend to find out from the archaeological record how the settlement at Ntsweng was organized. I intend to find if the settlement plttern at Ntsweng <:<>nfo~ed to the central cattle pattern. And with the aid of phosphate analysis and oral mtervIews, I intend to find out how labour was organized and space was used at Ntsweng. Methodology .. Archaeological survey is taking stock of everything that remains on an archaeological site in the form of plans, notes and photographs in as much detail as possible without excavating the site (Sharer & Ashmore, 1979). The archaeological survey of Ntsweng was done first by walking around the site to familiarize myself with the features and extent of the site. This was also done to choose an area to focus my study. The criteria employed for choosing the area to work were good preservation of stone alignments, sparse bush to allow good visibility, and a size comparable to the bulldozed area. After choosing the area, I started mapping the stones using a dumpy level. The instrument provided the bearing of the stones from the temporary benchmark we had created. A measuring tape was then used to take the distance of the features from the instrument. These measurements and angles were then plotted on graph paper. In addition, soil samples were collected and taken to the Archaeology Unit in the University of Botswana to test their phosphate content. This was done because it is known that human activities produce phosphorus-rich organic materials which after decaying are incorporated into the soil in the form of stable phosphates. These tend to preserve for thousands of years and can be detected by chemical analysis. This technique dates back to the 1920s when fieldwork in Sweden revealed the close correlation between ancient settlements and high concentrations of phosphorus (Renfrew & Bahn, 1991). Phosphate analysis is a geo-chemical technique the main scope of which is t? localize ancient monwnents not visible in a surface survey, to assist in detennination of site Iwnts and to give infonnation about the function, activity or duration of occupation. (Bakkevig, 1980:74) Proudford was able to estimate that activities of a POpulation of 100 people would deposit 124 kg of phosphorus annually (Clark, 1990). Recent phosphate analyses done in England have revealed that archaeological features that remain undisturbed in the subsoil are accurately reflected in the topsoil. !n the ~~ .topsoil was considered to ~ unstratified and hence devoid of archaeological infonnatlOn; Bahn,1991:87)It was often removed mechanically and quickly without investigation . (Renfrew & Cl~ (l~? says t~t phosphate tests respond mostly to middens cattle pits and domestic actiVity espeCIally around pits and buildings.

This was 24 then followed by adding two drops of amonium molybdate to the soil and allowing it to spread into the filter paper. Two drops of ascorbic acid were then added to the soil solution and left for three minutes to dissolve on to filter paper. It is important to have the chemicals reacting within a given time to avoid over-reaction. The soil was then removed from the filter paper which was examined. Sixty two percent of the filter papers showed no sign of blue colouring which means that the soil was <0.08 % P20S. Twenty three percent had a trace of blue up to 2 mm from the soil, which means that the phosphate content was 0.08 - 0.15 %. Nine percent were weak (blue circle, with rays merging) marking phosphate content of 0.15 - 0.8 %. And finally, 5 % were positive (distinct blue band 10-15 mm in diameter) marking phosphate content of 0.8 - 0.9 %. The control samples showed no phosphate content which showed that naturally the soil contained no phosphorus. After collecting the soil samples, oral interviews were conducted in Molepolole. These were used to help interpret the archaeological information at Ntsweng. A prepared questionnaire was used to guide the oral interviews (see Sekgarametso, 1995). A total of 21 informants were consulted in individual and group interviews. The group interview was conducted amongst a group of women known as Matsosa-Ngwao. These women are volunteers who have dedicated their spare time to the promotion of Kweneng culture. Thus they are mostly found at the Kgosi Sechele I Museum or at the kgosi-e-kg% 's kgot/a assisting where help is required. The information gathered from these women was checked by conducting individual interviews. Literature consulted was found at the National Museum, Phutadikobo Museum, Kgosi Sechele I Museum, National Library and University of Botswana Library. These books gave historical information about Bakwena and the stages that led to the abandonment of the site at Ntsweng. Other more general books about settlement studies conducted outside Botswana were also consulted Problems encountered during the research were mainly that the instrument I was using demanded a lot of labour. Thus, I spent more time in the field than I had anticipated. The more efficient Electronic Distance Measurer (EDM) was not working. Literature review Archaeological work done in Botswana is very limited, especially on historically documented sites. More historical archaeology has been done in neighbouring South Africa and it is information from these sites that would be most useful for comparsion with the settlement patterns at Ntsweng (e.g., Pistorius, 1992). This is because the occupants of Ntsweng are said to be part of the Sotho-Tswana group which came from South Africa (Ngcongco, 1982). More broadly, comparative studies on settlement patterns and use of space have been done worldwide and especially useful to my study is a book edited by Kent (199Oa) on domestic architecture and use of space. The contributors provide very important and original insights into the relationship between the built environment and the organization of space, though from different backgrounds. In their studies the fundamental role of culture as expressed in technology, symbolism, socio-political organization and economics is explored. This is done with the aid of case studies of the past and present drawn from various countries. Especially useful information in this book was Lawrence's study on urban housing in Switzerland where he argues that when studying settlement patterns one should not look only at specific buildings but also look at the diverse actors involved with their design (Lawrence, 1990). Kent's (199Ob) cross-cultural study of segmentation, architecture and the use of space saw Batswana as segmented into gender and age 25 distinctions when observing the relationship between use of space and domestic built environments. Information regarding survey techniques was available from a number of sources including Sharer & Ashmore (1979). Renfrew & Bahn (1991) and Knu~n (1978). They provided the necessary details including case studies in which archaeological surveys we~e done and interpretation of the results was given. Literature consulted on phosphate analy.S1S includes Nunez (1990), Shackley (1981), Bakkevig (1980) and Clark (1990). These prOVIde different ways of conducting phosphate analysis and include case studies. Particular~y useful was Bakkevig (1980) who points out some of the problems in phosphate analysts which have been done in the past and attempts to correct the mistakes .. Huffman (1986) has proposed a pan-southern African settlement system to explam southern Bantu settlements. This has been termed the southern Bantu cattle pattern or the central cattle pattern. This pattern, according to Huffman (1986:289) is " ... found among Bantu speakers in southern Africa who are predominantly partrilineal and who exchange cattle for wives". He further says that attitudes about economy, politics and religion result in a specific arrangement whereby an outer arc of houses, arranged according to some alternating system of status, surround a central zone that contains cattle byres, grain storage facilities, elite burials and the men's court. (Huffman, 1986:289) The settlement, says Huffman, was arranged in such a way that the front was public and reserved for dangerous activities and the back was sacred and private. He further says that the settlement pattern is governed by attitudes towards status. Using this model, I will investigate whether Ntsweng corresponds to Huffman's central cattle pattern. Pistorius' (1992) study of Bakwena settlement pattern near Rustenburg was especially useful. He conducted an ethnoarchaeological study in which historical, ethnographic and archaeological evidence was combined to interpret the settlement pattern at Molokwane. He further attempted to explain the way of life of the inhabitants of the village. Based on ethnographic and archaeological information obtained, Pistorius (1992) says that the settl~~ent had once been that of Bakwena. He found numerous wards occupied by related pamlineages (masika) and also found that the settlement pattern conformed to the central cattle pattern defined by Huffman (1986). McDonald (1940) conducted an ethnographic study of Bakwena material culture and architecture immediately after the abandonment of Ntsweng. Although his study mainly ~m~ the Bakwena ~f Molepolole and those in South Africa, he provided useful information about the SOClal, economic and political organization of Bakwena at Ntsweng. Lm:ssc:'n& Larsson .(1?84) documented traditional Tswana housing in Botswana. Their mam mterest was buil~g methods and they observed the layout of dwellings together with th~ use of space. Then book provides useful information for interpreting the stone altgnments at Ntsweng. Arc~l~gi~ wo~ ..., , ,... .. ,. ,.../,.,.- f ,f\], l)~ I .~ ,,," 32 .... -\ _, r- :• : • •- , 33 .
