Beneath the wheelhouse floors were a large number of pits, many containing articulated, dismembered or cremated animal burials, attesting to ritual practices. The site, which is the first wheelhouse excavation to be published for twenty years, has important implications for the structure, chronology functionand wheelhousesof Hebrideanthe in Iron Age.

Secondly, there is a detailed account of stratified groups of pottery from closed contexts of short duration; analysis of these groups gives a fixed point in CAMPBELL: EXCAVATION IROF STRUCTUREE SO NAG SOLLAT SA 195N SI 7 119 the controversial sequence of Hebridean pottery (Topping 1987; Lane 1990). Thirdly, the wheelhouse had an early phase of numerous pits, some of which contained a bizarre collection of animal burials and cremations. The nature of these pits poses problems for the interpreta- tion of the function of wheelhouses. This account does not discuss the implication of the results of the Sollas excavations at length. Recent projects by Edinburgh University (Armit 1988a; 1988b), Sheffield University (Branigan 1989) and the Scottish Central Excavation Unit (Barber 1984; Barbe t ale r 1989) shoul substantialld dad r knowledgou o yt f suceo h machair sites and hopeds i t i , , enabl abundane eth t data fro Sollae mth smora excavationn i et pu e b o st comprehensive regional context.

Crawford reports that the actual mound is known locally as Cnoc Slignich (Crawford 1986, 9) or Cnoc Sligeach (Crawford & Switsur 1977).

The apparent high density of sites in this area is almost certainly a consequence of the enthusiasm of Beveridge, who had bough e Vallath t y estate earlth yn ei centurye yearth f so . Modern surveys have shown that large numbers of unrecorded sites exist on the machair belt of the Outer Isles (Armit 1988a; Branigan 1989; Barber 1984; Lethbridge 1952, 193). Many of the wheelhouses in this area locate e seeedgee b th mo t f thi n so do s belt, especiall environmentaf yi l changes,e sucth s ha possible flooding of the Vallay strand machair, are taken into account (Scott 1948, 71).
