ground falls rapidly to the north. Towards Christ's Piece on 

 the south the ground rises with slight indications of terraces. 

 Malcolm Street is raised several feet above the original base of 

 the houses, the gardens of which on either side are much lower 

 than the street. Behind the Clergy School the ground falls 

 away from Jesus Lane. 



Along the street (Bridge Street) which leads to St Clement's 

 Church, the drainage operations exposed alluvial deposits, and 

 what looked like a rough wooden roadway on them. About 

 140 yards west of this point, in digging the foundations of the 

 new buildings of St John's College near the Master's Lodge a 

 great depth of alluvium was passed through. 



It is difficult to trace the margin of the alluvium from this 

 to Queens' College and the King's Mill, but we know that the 

 loop of the river which bounded u Garret Ostell Greene" on 

 the west has been filled up, and that the Library of Trinity 

 College stands upon made ground. 



In some excavations between Trinity Hall and the river the 

 alluvial silt was found passing under the made ground between 

 the College and the river. In this that queer discovery was 

 made of a human skeleton apparently secured between stakes 

 and fastened down into the bed of the stream. 



Close to King's College Bridge a great depth of made 

 ground was passed through, with much late mediaeval pottery 

 and bones, but I did not see any alluvium thrown out. When 

 the foundations of the new buildings of King's College by the 

 river were being dug I saw a great depth of made ground with 

 bones of domestic animals and pottery (medueval). At the 

 bottom there was some dark unctuous clay, probably alluvial. 



When a trial hole was sunk by the Corporation close to 

 Queens' College Bridge, in the attempt to prove that the gault 

 was unsound in places, and that Bullock's scheme was therefore 

 impracticable, the upper part of the section was through 

 gravel. 



Up the valley beyond this the boundary between the 

 alluvium and the gravel is obvious, but the great mass of made 

 ground obscures it along the outskirts of the ancient town, 

 where from 7 feet to 15 feet of transported earth covers all the
