A population concentration i n t he mountains i n t erms o f t he model would mean t hat more s ites w ith a h igher density o f cultural r emains could b e expected i n t he mountains t han i n t he f oothills.

While i n t his study evidence i s advanced f or one optimum s olution t o an adaptation problem i n a specific t ype o f environment t he writer i s aware o f t he fact t hat o ther adaptation possibilities could h ave o ccurred. I t would b e very d ifficult t o f ind any meaning i n observations o f t he subsistence ecology o f Holocene h untergatherers w ithout using analogues f rom ethnographical s tudies o f t he r emaining B ushman t ribes i n South Africa.

The population density o f h unter-gatherers i n an area i s c ontrolled by t he productivity o f t he f ood r esources w ith c onsideration o f food preferences o f t he group and c onsumption t hereof. According t o t he model o f Hassan ( 1981:8) for t he c alculation o f population densities o f present-day hunter-gatherer groups, b ased on r esource potentials and t he e ffectiveness o f t heir e xploitation, t he d ensities vary b etween 0 ,01 and 9 ,5 p ersons p er s quare k ilometre.

I n 1 929 appeared t he c lassic work o f Goodwin and V an R iet L owe o n t he S tone Age and i t was t o r emain t he b asis o f South African archaeological t hought up t o t he 1 960 's. Of i mportance is t hat i t brought t he t erm L ater Stone Age i nto common use and even nowadays t he t erm i s still used by archaeologists e specially i n a t echnological s ense ( Plug 1 978:21; Thackeray, A .I. 1 981:13; D eacon, J . 1 982:9). I t i s a lso used i n t his work and i ncludes artefact assemblages characterised by f lakes w ith plain striking platforms, i n s ome i nstances m icrolithic elements and various t ypes of s crapers. At present t he c ommencement o f t he L ater S tone Age is placed i n t he l ate P leistocene , approximately 2 5 000 years a go ( Thackeray, A .I. 1 981:13; D eacon, J . 1 982:36). Problems were a lso e xperienced, during t he writing o f t his study, w ith t he m eaning o f t he word ' industry' which i s o ften used i n connection w ith t he L ater Stone Age b ut i s u nsatisfactorily defined. An i ndustry i s s een a s t he assemblage of a ll artefacts which was m anufactured by a prehistoric group o f p eople i n an area d uring a specific p eriod ( Bishop & C lark 1 967:893). Accordingly i t has m eaning f or a defined area i n which only one Holocene population should be present. W ith possible e xception of the W ilton i ndustry ( Deacon, H .J. 1 976) i t c an b e said t hat not o ne o f t he present i dentified i ndustries i n South Africa satisfies this definition. Yet i t i s c lear on the b asis o f e xisting k nowledge t hat t he L ater S tone Age i s a t echnological stage, consisting of s everal s ubstages, o f t he South African S tone Age t hat o ccurred over a w ide area i n South Africa. I n t his study i t i s s een a s sufficient t o i ndicate t he r elationship o f t he artefact a ssemblages f rom t he v arious s ites w ith t he d ifferent t echnological s ubstages. T he c ulture h istorical f ramework o f Goodwin and V an R iet Lowe ( 1929) r ecognised t wo i ndustries i n t he L ater S tone Age o f South Africa n amely t he W ilton and t he Smithfield. Both were v aguely defined and t his l ed t o the appearance of various r egional variants. I n t he f ollowing years archaeologists attempted t o f it t heir artefact assemblages i nto t his f ramework. The presence o f m icrolithic elements, e specially segments, was used t o c lassify an assemblage as W ilton while other assemblages were s een as Smithfield ( Inskeep 1 967). According t o t he model o f Goodwin and Van R iet L ouw ( 1929:150) t he W ilton c ame f rom t he north o f Africa t o S outh Africa by means o f waves o f i mmigrants.

I llustrations show s crapers s imilar t o t hose a ssociated w ith t he e arly Holocene i n t he study area. Two rock shelters were e xcavated by Laidler at Nqamakwe ( Laidler 1 933) ( Fig.1). The d eposits i n rock shelter B contained a Middle Stone Age artefact a ssemblage f ollowed by a L ater Stone Age a ssemblage which was i dentified a s ' Smithfield'. The d eposit i n shelter C consisted o f t hree l ayers w ith Smithfield A , B and C a ssemblages. A f ew potsherds were f ound i n t he youngest l ayer and bone was preserved t hroughout. Laidler e xcavated another s ite i n the Ngcisininde Valley, 32 km f rom Tsomo ( Laidler 1 937). S even occupation l ayers were r ecognised i n a deep d eposit ( 2,7 m deep) f rom which potsherds, bone and stone artefacts were r ecovered. The potsherds f rom l ayers 1 and 2 were e xamined by D erricourt 1 977) and he sees t hem as b elonging to t he Later Stone Age. Apparently Laidler could not f ind any s egments or b acked blades i n h is e xcavations d espite c areful observations. H e a lso questions t he validity o f t he development w ithin t he Smithfield a s proposed by Goodwin and Van R iet Louw ( 1929)). After a l ong h iatus i n systematic r esearch B .D. Malan ( 1955:1-26) m ade a superficial survey o f archaeological s ites i n E ast Griqualand. I t was f ollowed by an excavation a lso i n t his area in 1 961 ( Farnden 1 966). The shallow deposit c ontained only a small a ssemblage o f artefacts and no mention i s m ade o f bone r emains. The contribution t hat t he early r esearch attempts c an m ake t o t his study i s l imited. The descriptions i ndicate t he d istribution o f Later Stone Age groups and possible t echnological a ffinities. E XPLANATORY
PHASE
T he approach t o archaeological studies i n South Africa started t o change during t he l ate 1 960's and t he r equirements f or r esearch b egan t o place more emphasis o n explanation t han o n mere description. Dissatisfaction w ith t he W ilton and Smithfield concepts ( Inskeep 1 967) l ed t o determined attempts o f r edefinition. T he W ilton Rock S helter was r e-excavated and t he m aterial analysed ( Deacon, J . 1 974:12). A model presenting t he Wilton as a system developing t hrough d ifferent growth phases was g enerated. These growth phases c an b e s een as t he r esult o f adaptation t o t he environment ( Deacon, J . 1 972:38). T he e xistence o f t he W ilton and Smithfield as t wo s eparate entities was now questioned ( Deacon, J . 1 974:12) and t he possibility t hat only o ne t echnological complex had b een present i n South Africa during t he m iddle and l ate Holocene was suggested. T he use o f animal and p lant r emains i n archaeological e xplanations l ed t o an ecological approach f or the solving o f archaeological problems. The t endency was now t o move away f rom t he l ithic centred v iewpoint that characterised t he previous 30 years t o an approach which t ried t o f ind models t hat c ould explain t he e xploitation o f t he environment by t he

For the Cape Fold mountains a model

Each o f t hese s ectors r epresented a d ialectic group compounded of smaller subsistence groups ( Deacon, H .J.1976:170). The i mplication o f t he above mentioned models i s t hat gradient areas w ith t heir complementary natural r esources were preferred by Holocene hunter g atherers a lthough t he coastal areas were a lso exploited. I t was observed i n t he s outhern and e astern Cape t hat a s equence o f t hree t echnological substages o ccurred i n t he Later Stone Age i .e. t he Robberg ( 20 000 1 2 000 B .P.) c haracterised by b ladelets f rom small blade cores t ogether w ith a f ew small s crapers and b acked t ools; t he Albany ( 12 000 8000 B .P.) characterised by l arge s crapers and an absence o f backed t ools; t he W ilton ( 8000 - h istorical t imes), characterised by s mall s crapers and b acked t ools as well as a variety o f o ther t ools ( Klein 1 974a; D eacon, J . 1 978). During the l ate P leistocene and t erminal P leistocene l arge and medium l arge grassland g ame species were mostly h unted while t he m anufacturers o f t he Wilton t echnological substage started t o concentrate f rom early Holocene t imes on t he smaller t erritorial g ame. The e xplanation f or t his shift l ies i n h uman adaptation t o changes i n vegetation f rom m ainly grassland t o f ynbos ( Deacon, H .J. 1 976:161). The spread o f t he m icrolithic t echnique associated w ith t he W ilton i s d escribed as d iffusion a long social and l anguage routes ( Deacon, H .J. 1 976:170) i n contrast t o t he e arlier v iewpoint f avouring m igration waves. R edefinition o f t he Smithfield has b een attempted by S ampson and i s b ased on t he r esults o f a s eries o f 1 1 e xcavations which were executed i n t he p eriod 1 965-1967 i n t he Orange R iver S cheme r egion. This area l ies o n t he border b etween t he Orange Free State and t he northeastern Cape and i ncludes t he t raditional d istribution area o f t he Smithfield. Strictly speaking Sampson's work c an b e s een as a continuation o f t he descriptive phase ( Sampson 1 967, 1970, 1 972, 1 974). H e succeeded i n f inally proving t he s equence i n t he Smithfield according t o Goodwin and Van R iet Lowe as i nvalid and i dentified i nstead s ix stages o f devolopment i n t he various deposits ( Sampson 1 970:1). This s equence was l ater r evised by h im t o i nclude f our I ndustrial Complexes i .e. Oakhurst, W ilton, Smithfield and S trandloper ( Sampson 1 972:288). I n a f urther d escription o f h is c lassification s cheme phase 1 or Smithfield A i s a ssigned t o t he Lockshoek i ndustry ( 12 000-8000 B .P.), p hase 2 -5 t o t he i nterior W ilton i ndustry ( 8000-500B.P.) and phase 6 t o t he Smithfield i ndustry ( 500 B .P. and l ater)(Sampson 1 974). Sampson's r esearch r esults certainly stimulated archaeologists i nvestigating Later Stone Age s ites i n t he i nterior o f t he c ountry. H umphreys ( 1979) f ound t he s ix phase b ecause no s ingle s ite contained a ll

u nacceptable phases and
e specially t he stratigraphic context and age o f phase I could not b e proved. Sampson a lso used arbitrary units i n most o f h is e xcavations and not c learly d efined occupation l ayers. Even an attempt by S ampson t o apply h is c lassification s cheme t o t he whole o f South Africa's L ater Stone Age was not g enerally accepted b ecause o f i nsufficient data ( Thackeray, A .I. 1 981). I t i s i nteresting t hat advanced s cale and cluster analysis o f a rtefact a ssemblages f rom t he Orange R iver S cheme a rea r evealed a s ignificant r elationship b etween phase 1 a ssemblages ( Southard 1 975:34). The i nvestigation by Southard a lso c onfirmed t he sequence o f Oakhurst, W ilton and Smithfield. An e xcavation i n M erino Walk c ave, s ituated i n t he f oot h ills o f t he Stormberg, was conducted a s part o f t he Orange R iver S cheme project ( Sampson 1 970)(Fig. 1 ). The e xcavation i s o f i mportance for t his study b ecause i t i s s ituated approximately 1 5 km north o f Grassridge, which i s o ne o f t he k ey s ites i n t he project. Dates f or t he deposit are l acking b ut t he d iscussion o f t he small artefact a ssemblage suggests t hat i t b elongs t o t he same p eriod a s Grassridge, i .e. e arly Holocene. Fourteen sterile l ayers covering t he occupation m aterial i ndicate t hat Merino Walk was l ike Grassridge w ithout human i nhabitants f or a l ong t ime. An extensive archaeological survey program was u ndertaken by D erricourt i n t he C iskei and T ranskei r egions during t he e arly 1 970' s. P art o f t he survey was an e xcavation i n a rock s helter on t he farm Oakleigh i n t he Queenstown d istrict ( Derricourt 1 977). The deposit was t he r esult o f t wo p eriods o f o ccupation. The earlier one was characterised by an artefact a ssemblage t hat i ncluded f ew f ormal t ools b ut a c onsiderable number o f utilised artefacts. A s econd phase f rom 2090 ± 5 5 B .P. ( Pta-671) f ollows a break i n habitation. A s eries o f f our r adiocarbon dates shows t hat t he shelter was c ontinually v isited u ntil h istorical t imes. Pot sherds appear a fter 1 040 ± 5 5 B .P. ( Pta-935). T he fauna i s typical o f a grassland environment with small t o medium-small antelope abundant.

The hunting p attern o f small t o medium small game i s a lso s imilar t o t he hunting strategy f ollowed at Grassridge. Of s ignificance f or t his study i s t he work by Carter i n e astern Lesotho during 1 967-1974. F ive s ites were e xcavated d uring t he f ieldwork w ith one, B elleview, s ituated i n E ast G riqualand close to t he Lesotho border.

THE HISTORICAL
PERIOD
T he hypothesis and model t hat t his study e xamines are b ased m ainly o n ethnohistorical observations m ade during the f irst h alf o f t he nineteenth century. I t i s t herefore n ecessary t o m ake an appraisal, using k nown h istorical sources o f t he d istribution, material culture and customs o f t he B ushman population o f t he northeastern Cape during t his p eriod. I n t his s ection the i ncreasing pressure t hat B ushman groups e xperienced f rom black t ribes and white settlers w ill b e r eviewed and r eference w ill b e made to specific observations t hat throw l ight on the l ifestyle o f t he B ushmen during t heir l ast years o f i ndependence i n the Drakensberg mountains o f t he northeastern Cape. I n D erricourt's archaeological surveylthe area o f d istribution o f t he B ushman b ands i n the e astern parts o f t he Cape f rom t he 1 7th century i s d epicted a s t he r egion north o f t he Amatola Mountains up t o t he S tormberg, t he upper r eaches o f t he K ei R iver and t he upper parts o f t he Transkei up t o t he Drakensberg e scarpment. I n t he c oastal areas o f t he C iskei and T ranskei t he southern Nguni t ribes a s well a s t he Gonaqua, a Hottentot t ribe, were a lready present before t he 1 600s. T he t ime o f arrival o f t he f irst Nguni groups i n the Transkei and C iskei i s uncertain b ut o n t he e astern Cape coast, at C halumna R iver mouth, pot sherds ( Shixini ware) s imilar to E arly I ron Age ware f rom Natal were f ound i n a m idden ( Derricourt 1 977:107; Maggs 1 980:9). During building activities on t he c ampus o f t he University o f Fort Hare a h uman skeleton was found approximately 0 ,6m under t he surface i n association with a f ew pot sherds. A metrical analysis o f t he skeleton r evealed strong negroid characteristics ( P. Banghart, personal communication). W ear o f t he t eeth i s s imilar to that o f p eople eating cereals ground w ith a grinding stone. A radiocarbon d ate o f 880 ± 50B.P.(Pta-3101), f rom bones o f t he s keleton, i s evidence that a group of I ron Age a griculturalists was a lready west o f t he K ei R iver about 1 000 years ago. Observations at both Chalumna R iver and M iddledrift ( Derricourt 1 977) showed t hat pastoralists ( Hottentots) were i n the e astern Cape even earlier t han t he a griculturalists. I n L esotho t he s ettlement o f b lack tribes o nly t ook p lace during t he 17th century ( Maggs 1 980:12).

I ntermarriage w ith t he blacks t ook place ( How 1 962:11) and s igns o f acculturation, which i ndicate peaceful contact, were observed ( Wright 1 971:9). This study a lso produced ample evidence t o prove t hat B ushman b ands occupied t he Drakensberg t housands o f years b efore t he arrival of t he f irst pastoralists and agriculturalists and t hat they were not driven t here by t hem ( Kay 1832:476; W illcox 1 956:27). At t he b eginning o f t he 1 9th century t he D ifaqane conflict b etween t he b lack t ribes o f Natal and L esotho was i n f ull swing and t ogether w ith clashes w ith t he White s ettlers i t l ed t o t he e xtermination o f t he Bushman t ribes i n the northeastern Cape. Matiwane, chief o f a l arge Nguni t ribe ( the Ngwane), f led from Natal after b attles w ith t he i mpis o f Tshaka, penetrated i nto Lesotho i n 1 827 and eventually r eached t he d istricts o f Wodehouse, Barkly-East and Queenstown ( BarklyE ast R eporter 1 973; Omer-Cooper 1 978:86). T his group, comprising hundreds of f ugitives, must have been strong competition f or the hunter g atherers o f t hese areas for the natural f ood r esources. Many farm and place names are r eminders o f t his period for i nstance F etcani Glen, F etcani Pass, Maxongoshoek, Lehannes Pass. More pressure on t he hunting areas o f the B ushmen were e xerted by white farmers appearing w ith t heir families and l arge h erds o f l ivestock i n 1 845 i n t he v icinity o f t he Kraai R iver ( Barkly-East R eporter 1 973). The l arge game r esources o f t he Drakensberg and t he f oothills were depleted shortly a fterwards and that contributed to a pattern o f stock t heft and r eprisals t hat continued up t o the 1870s. As was t he c ase w ith t he stockfarmers o f Natal ( Wright 1 971) t he f armers o f t he northeastern Cape also suffered l arge losses i n stock as t he r esult o f r aids i n t he period 1 840 t o 1 875. Some of t he i ncidents are still r emembered. A b and o f stock t hieves was surprised on t he farm Denorbin ( Barkly-East d istrict) by farmers f rom Vaalhoek f ollowing the t racks o f t heir stolen c attle ( Mr. Small, personal communication). A skirmish a lso t ook place on t he farm T he Caves where B ushmen drove stolen stock i nto a v ery l arge c ave ( Barkly-East R eporter 1 973). T he s ituation was complex and i n the Drakensberg r egion o f t he northeastern Cape and Natal, B ushman b ands robbed stock f rom both blacks and whites. Sometimes black b ands, bushman and hottentot groups r aided t ogether i n Nomansland ( East Griqualand)(Vinnicombe 1 976:67). White farmers, Xhosas and Hottentots a lso undertook e xtermination e xpeditions against t he guilty parties. Rock paintings, dating t o this conflict p eriod, on t he farm Nelsrust ( Elliot d istrict) i nclude p ictures o f t he f irst white s ettlers, s oldiers and the Nguni. D espite t he pressure exerted on t hem because o f stock theft activities, t he B ushman b ands i n the Drakensberg o f t he north-eastern Cape were still enjoying a measure o f i ndependence o f movement i n 1 850.

The veld t ype is H ighland sourveld and Dohne-sourveld ( Acocks 1 975:82) and occurs on s oils derived f rom t he Molteno s ystem at h eights varying b etween 1 350m and 2 150m. The origin and prevailing nature o f t he grassland i s probably due t o a ccidental or d eliberate burning ( Killick 1 963; Tainton 1 981:22). Grasses, which are i mportant for grazing, i nclude T hemeda triandra. T he dominance o f t his type o f grass i s the r esult o f r egular burning ( Robinson et a l 1 979). T ristachy h ispida and H eteropogon contortus are a lso present. Overgrazing o f the v eld by c attle stimulates t he growth o f Erogrostis plana while A colypha schinzii dominates when o vergrazing by sheep o ccurs ( Acocks 1 975:83). Large patches o f s outhern tall grassveld or m ixed veld grow i n t he r iver b asins. The dominant types o f grass h ere are T hemeda triandra and H yparrhenia h irta ( Acocks 1 975:102).

Smaller patches grow s outh of Mt F letcher and i n t he K inira valley north o f Mt Frere. The growth p eriod o f t he grasses is between S eptember to April ( Tainton 1 981:33) and t he protein content and t herefore n utritional value o f the southern tall grassveld d iminishes considerably s lower d uring the summer t han is the c ase with t he surrounding sourveld s o that i t c an supply grazing for at l east t wo months longer.

I NTRODUCTION The Ravenscraig rock s helter ( 27 ° 4 7 ' 30"E ; 3 1 ° 00 ' 4 5" S ) ( 1850 m above sea l evel) i s t he northern most o f f our rock s helters located within about 1 km o f e ach other i n t he sandstone rock-faces on t he western s lopes o f t he Sterkspruit k loof o n t op o f t he Drakensberg e scarpment ( Fig.1). T he s ite c onsists o f t wo sections namely a rock o verhang 30 m l ong and 1 6 m deep i nside t he dripline, which e xtends on t he northern s ide i nto a c ave 20 m deep and 1 0 m w ide ( Fig.53). T he entrance to t he c ave was c losed o ff w ith a stone wall by t he owner o f t he farm. A collapsed stone wall 5 0 m away f rom t he s helter shows t hat t he s ite at o ne t ime served as a k raal. The whole •f loor surface o f t he shelter and c ave i s c overed by a ashy deposit t hat gradually s lopes i n t he d irection o f t he Sterkspruit 1 00 m away. The d eposit appears t o b e u ndisturbed but t here are i ndications t hat t he roots o f a n earby poplar grove are penatrating i t. T he shelter and e specially t he c ave gives good protection i n a ll w eather c onditions. A f ew faint paintings are v isible against t he f ront roof s ection o f t he shelter. Some h uman f igures wearing k arosses are depicted on t he s ide o f a l arge rock i n f ront o f t he s helter. A small panel w ith well preserved e land p aintings appears on t he rock f ace about 1 5 m north o f t he shelter. A l arge s helter 500 m t o t he south, used at present as a sheep k raal, contains t he r emains o f paintings but m any have b een d estroyed by activities i n t he kraal. T he s helter has a southern a spect o ver t he Sterkspruit v alley which has a grassland plain a s i ts bottom. T he v eldtype i s Themeda-Festuca grassveld ( Acocks 1 975).

The r esemblance b etween t he areas above and b elow t he e scarpment d uring drier warmer t imes was p erhaps greater t han during cooler wetter p eriods.

The h unting o f l arge grazers at t he end o f t he Pleistocene and t he b eginning o f t he Holocene confirms a pattern t hat has a lready b een i dentified i n t he eastern and southern Cape f or t his p eriod ( Deacon, H .J. 1 976; D eacon, J . 1 982, 1 984). The m aintenance o f a s imilar subsistence system o ver a l arge area during t he l ate Holocene provides a meaningful new d imension t o t he study o f t hese systems. I t contrasts with observations i n t he southern and e astern Cape where, when a more c losed v egetation c over appeared c . 8 000 years ago, t he grazers d isappeared and subsistence strategy focused on p lant f ood and s mall t erritorial g ame ( Deacon, H .J. 1 983b). E lsewhere during t his period bands i n g eneral l imited t hemselves t o small areas o r patches and were not adjusted t o t he hunting o f mobile h erd g ame. Accordingly, i n areas where t hese animals were present, f or i nstance Grassridge or i n t he r egion o f t he Orange R iver S cheme, t hey d id not try t o h unt t hem i n l arge n umbers b ut r ather r estricted t hemselves t o t he more stable small game.

I n v iew o f t he f act t hat i t was t he Drakensberg v alleys and t he m ixed grass patches l ower d own which were exploited by t he l ate Holocene population, i n accordance w ith t he proposed model ( Fig. 6 9), t he i mpression i s created o f a v ery l ow population d ensity i n t he r egion a s a whole. I t would t herefore be m uch more r ealistic t o c onsider t he population n umbers i n r elation t o t he s izes o f t he above mentioned k loofs and v egetation patches. A model which proposes t hat t he prehistoric i nhabitants o f t he Drakensberg m aintained a subsistence system t hat c entred on mountain food r esources and i n t imes o f s carcity supplemented t heir stock by e xploiting f ood r esources at t he f oot o f t he e scarpment, i s a t estable a lternative t o t he model o f l inear movement i n t he subsistence system o f b ands t hat i ncluded s easonal transhumance f rom t he Drakensberg i n t he summer t o t he c oast i n t he w inter ( Carter 1 970; C able 1 982).
