Within this report the results of two field surveys on neighbouring sites lying north of the Arbury Estate, Cambridge, are presented. These investigations were undertaken within the broader context of the Cambridge Archaeological Unit�s ongoing Arbury Environs landscape project. These two sites are interrelated and the evidence of each reflects upon each other. Both were undertaken by the same field team, one directly after the other and, in fact, the results of the second survey (the Gypsy Ditches) caused us to re-examine the still exposed sections of the first (The Unex Lands). It is appropriate, therefore, that these two sites are, so to speak, herein �bound up� together. Neither of these sites produced substantial artefact assemblages and, moreover, what �early� pottery was found was very abraded.

An archaeological watching brief was executed at the Coles Lane Recreation Ground, Milton, Cambridgeshire. Despite the considerable evidence from aerial photographs and cropmarks on the ground for archaeological deposits, no ancient remains were discovered.

Following advice from the County Archaeologist concerning the proposed development of two tennis courts in the orchard at Sawston Hall, an archaeological evaluation was undertaken in order to establish the presence/absence and character of any archaeological remains possibly associated with the sixteenth century hall or the earlier building of Pirot's Manor (S.M.R: 01267). Of prime concern was the location of the possible north leg of the 'moat' which was thought to flank the northern bank of the garden.

This project was commissioned by Mott-MacDonald on behalf of the Department of Transportation. The project brief consists solely of a desktop study of the known archaeology in the area around the five proposed routes for the A1(M) widening from Baldock to Alconbury. The aims of this project are: 1. to determine the direct threat to known sites along each of the five routes, 2. to provide some determination of the degree of probable archaeological density along the routes, 3. to present areas of particular archaeological sensitivity and areas of high archaeological potential, 4. to provide some measure of archaeological destruction for each proposed route.

An archaeological watching brief was undertaken during the building of a new sewer at Madingley hall, Cambridgeshire (NGR TL 394 604) . Archaeological deposits were observed from the early medieval field; the early 18th century formal gardens; the 1756-7 landscape gardens of capability Brown; and the late 19th and 20th century demolitions and re-buildings. Roman and Saxo-Norman pottery was recovered.

An archaeological field evaluation was undertaken across a c.80ha. site located on the eastern side of the village of Longstanton, Cambridgeshire. A variety of investigative techniques were employed (e.g. test pitting and transect fieldwalking). And their respective rates/biases are compared. In the course of this work, the site�s upstanding fieldsystems were plotted and its headlands sectioned. A windmill mound of that date, which seals a later Iron Age settlement, was discovered. Two previously known, major cropmark complexes were also investigated. Both proved to be primarily of Romano-British date, while including an Iron Age component. Apart from the evidence of these Iron Age and Romano-British sites, the main contribution of these investigations in relationship to the later prehistoric archaeology of the region is largely negative. In the report�s concluding discussion the results of the survey are compared with other recent investigations on �land-locked� (inland from rivers and the fen-edge) gravel terraces within the clay basin north of Cambridge. It is argued that this region may not have been intensively settled/utilized until the later Iron Age.

A watching brief was conducted by the Cambridge Archaeological Unit of work in advance of the construction of a rear extension to 21 Magdalene Street, Cambridge. The preparation involved the demolition of the existing yard and outbuildings, the removal of the concrete footing of these structures and the excavation of two foundation trenches as footings. The trenches were hand dug by the developers to a depth of c. 0.90m and a width of c. 0.80m. Features and deposits were observed in section only; consequently recording was not as extensive as it might otherwise have been. Present day Magdalene Street follows the course of the important southeasterly route into Cambridge which spans the River Cam at a narrow crossing point. The site lies some 200m from the Castle Mound, centre of the old upper town, and falls therefore in an area of considerable archaeological interest.

Following an initial assessment of an area of proposed housing development at Caxton, Cambridgeshire (NGR TL 30150/58480) a further trial trench was excavated. A ditch had been located which contained llth-12th century pottery. The sherds were large and unabraded which suggested that they were domestic refuse from a nearby settlement. A further trench was therefore required in order to establish whether any traces of that settlement were within the proposed area of development to the north of the ditch.

This desktop study, commissioned by ARC Ltd., evaluates the archaeological impact of the proposed re-activation of the c. 170ha Block Fen, Mepal Quarry (which actually lies in Langwood Fen, Chatteris). Apart from the actual area of the quarry itself (Zone I), this study extends to two further surrounding 'zones': II- A 'boxed' (developer-designated) c. 500m wide berm around the north, west and eastern sides of the quarry so as to evaluate the effects of de-watering. Ill - A further c 1km wide box so as to provide a sense of broader landscape context and allow for the identification of sites that might extend into Zone II but which may have evaded aerial photographic recognition. This area extends north to Vermuden's Drain and east of the Bedford Level (fig. 1). While no excavation has occurred within this immediate area, it has been extensively surveyed. It was recently fieldwalked by David Hall during the English Heritage Fenland Project, and he has made available to us all of his records. In conjunction with that project Roger Palmer has compiled and analysed the area's aerial photographic coverage, and he has provided a summary of his researches. Albeit in an intermittent and informal manner, since 1963 the area of Langwood Hill has been fieldwalked by local amateurs and, in recent years, extensively surveyed by a metal detector.

In July 1991 a survey, sponsored by Trinity Halt was conducted by the Cambridge Archaeological Unit of machine-cut trenches within a College-owned field on the north side of Cambridge (NGR TL 471 / 618). The field lies to the northwest of the current boundary of the Science Park, and south of the A45. It represents the latest block of land to be examined as part of the Cambridge Archaeology Unit�s ongoing Arbury Environs Project. The Unit has previously investigated three sites within this area: the Arbury Camp grounds (Evans 1991a); the Unex Lands and the Gypsy Ditches Site (Evans 1991b ). The adjoining King's Hedges Farm Site was investigated by the office of the County Archaeologist (Ette 1991).

An archaeological watching brief and assessment was carried out at Chevington Place, Ely, Cambridgeshire. Ridge and furrow was recorded but evidence of earlier archaeological remains was not discovered.

An archaeological assessment was undertaken in advance of planning permission for the development of an area of rough pasture at �the Parks� Godmanchester (NGR TL 2460/7080). Archaeological features were recorded from a Medieval fish pond system linked to a moated manor, overlying infilled Roman quarries and associated features situated to the north of the Roman town.
