Pratt called attention to the work being carried out on the Victoria County History. He produced for the information of members an account of the project by Mr. W. R. Powell, Editor of the Victoria County History of Essex. Mr. Kenneth Marshall, Curator of the Passmore Edwards Museum, then gave an account of the first season's work in excavation on the site of the old Thorndon Hall. The lecture was illustrated by lantern slides, plans and blackboard drawings. He has kindly provided the following notes on the subject. The remains of Old Thorndon Hall are located on a south-facing slope of London Clay in the parish of West Horndon, Excavations on the site during 1957 have been principally of an exploratory nature. The first object was to examine the area of the house, now covered by thick woodland, and to identify at least one point in relation to the existing 18th century plans. A grid of squares was then laid down to cover the point so identified and the immediate neighbourhood completely excavated down to undisturbed levels. The point tentatively identified during the early summer was an angular wall near the western-extremity of the area covered by ruins. This was thought to be a part of the structure noted on the plans as the Great Tower. Its identification was made certain at an early stage when the foundations of a large bay window were uncovered to the west of the "Tower" and in a position corresponding closely with a similar window shown on the plan. Inside the angle of the bay window a narrow, brick-lined pit was discovered, leading down to an area of vaulting supporting the upper walls. These vaults were tightly packed with reused London clay containing much human debris. Outside the window the excavation was continued down to natural, reached at a depth of 13 feet.
