Report by W Goddard on the original water supply to the Sanatorium, built 1871-84. An artesian well supplied the water storage tank in the water tower, which provided the hydraulic pressure for hot and cold water services around the hospital complex. Over the years, a series of artesian wells had to be sunk as silting affected the earlier ones. During redevelopment of the hospital site one of these former wells was revealed. J Mills reported that a further water reservoir was a below ground tank, also revealed during the recent works. (SIHG 98)

Report by P Tarplee on research into the estate’s hydraulic rams, by the Surrey Gardens Trust. The rams were supplied in 1922 by Green & Carter of Somerset, who have comprehensive records dating back to 1836. These show that a ram was supplied to the estate in 1875. One was also supplied in 1851, with valves for another ram, presumably installed before the start of the existing records. (SIHG 101)

A watching brief by D W Williams of work to this property, which cuts into the slope below the castle. Subsidence resulted in the destruction of a 19th century brick baking oven and a stone and brick revetment, before recording could take place, as well as the rear wall of this 16th-17th century building. Subsequent observation revealed a buried soil layer, which contained early Mesolithic flint blades and 13th century pottery, that had been disturbed by excavation, presumably for sand, at some point in the 13th century.

A survey of the barrow was carried out by K Pringle for BHRG and SyAS. Examination of the section revealed by the removal of a retaining wall constructed c.1924 revealed no evidence for turf lines. A number of struck flints were recovered from the backfill of the retaining wall and one flake was recovered during the cleaning of the section. Further examination of the barrow revealed that a substantial air raid shelter had been constructed within it. (320)

Observation by S Dyer, for SyAS, of disturbance caused by the excavation of a series of trenches for an irrigation system on the golf course, adjacent to the Roman villa. North of the villa site a concentration of Romano-British tile was observed but these may have been redeposited previously, to infill a hollow of some kind. Elsewhere a few sherds of greyware pottery were recovered. The disturbance was also observed by the BHRG who collected a quantity of Roman pottery, mainly 3rd century greywares, and also noted the concentration of tegula and imbrex tiles. (313)

A watching brief by D W Williams of SyAS on works to underpin a toilet block recorded part of a substantial structure constructed of chalk blocks with brick facings; the floor of the structure was of clay with parallel timbers at short distances apart. The structure had been infilled with brick rubble and silty clay. No dating evidence was recovered but the structure is probably early 19th century in date and presumably relates to water management in the landscaped gardens around the Priory. (302)

Excavation by D W Williams, for SyAS and SCC’s Planning Dept, continued. The full extent of the prehistoric pit concentration was confirmed, with no sign of an encircling ditch or other defining boundary. A preliminary examination of the pottery recovered from these features indicates that conjoining pieces of Grooved Ware were deposited in different pits, although no vessel appears to be completely reconstructable. Examination of the pottery associated with the later enclosure to the south suggests usage from the very Late Iron Age through to the early 2nd century AD. (307)

Excavation by S Dyer, for SyAS, continued on the site of a villa first excavated in 1877, with the aim of establishing the size of the complex and the location of the 19th century excavation. The work established the plan of a western range of what is presumed to be a corridor villa, but not the full extent of the complex. The results suggest different phases of construction, with the western range possibly being the earliest and the northern range the latest. Finds recovered range from mid/late 1st century to late 4th century AD.

Fieldwalking by J English of SyAS of an area where Iron Age finds have been reported revealed little of archaeological interest.
