Vol. 68.] GLACIAL SECITONS EOUND SUDBUKY. 23 



3. The Glacial Sectiois's round Sudbttet (Suffolk). By the 

 Eev. Edwin Hill, M.A., F.G.S. (Read December 20th, 

 1911.) 



The sections round Sudbury are called in the Geological Survey 

 Memoir of 1885 'perhaps about the finest in any inland spot in 

 East Anglia.' They are described in the Survey Memoir on 

 JN'orth-'VVest Essex (1878) ; and there are further notes in that 

 on Ipswich, Hadleigh, etc. (1885). 



There is a paper by Dr. Marr in Geol. Mag. 1887 (p. 262) ; there 

 have been excursions to the neighbourhood on the occasion of the 

 Geological Society's Centenary in 1907, and by the Geologists' 

 Association in 1898 and 1910, of which brief descriptions have 

 been published. I know of nothing else. Since publication of the 

 two Survey Memoirs some pits have been closed ; some new ones 

 opened ; and many extended considerably. These changes have 

 disclosed facts of considerable interest, which deserve to be put on 

 record. 



I. The Pkincipal Pits. 



I will name the position and contents of the principal pits, 

 giving numbers to them for use in this paper and notes of 

 references to them in the Survey Memoirs. 



Beginning with those on the high road leading eastwards from 

 the town, Green's Pit(l) has been filled in, but the singular 

 contorted sands ^ are still visible. On the south side of the road 

 two pits (2) called Victoya on the Ordnance Map and in the 

 Geological Survey Memoirs,'^ now joined at the top, show Chalk, 

 Thanet Sands, Crag, gravels, and a patch of Boulder Clay. Farther 

 out along the road, on Gallows Hill,^ two brickworks (3), called 

 California on the Ordnance Map, show bedded silts and upon 

 these Boulder Clay. 



The high road which runs out of the town south-east towards 

 Newton, passes on its left (north-east) side, W ho r low's (4) Chalk- 

 pit^ (Chalk, Thanet Sands, Crag, Glacial Gravels, and clay) and 

 next, the entrance to the Alexandra Brickworks. Here are two 

 pits^ : the outer (5),^ nearest to the road, contains Thanet Sands, 

 Crag, Glacial Gravels, Boulder Clay ; the inner (6),' half a mile 

 from the road, very large, shows bedded silts and Boulder Clay, like 

 those in the Gallows-Hill Pits (above, 3), which are indeed across
