The interest of this section lies in its corroborating the evidence 

 for a deep channel of Drift, given by the section at St. Peter's Quay, 

 New Mill, showing a depth of 127 feet to the Chalk, whereas at 

 Messrs. Turner's foundry (close by to the west) it is but 70 feet. 1 

 All three show a considerable thickness of Drift, the top of the 

 Chalk being lower than on the rather higher ground northward, as 

 the following section, as well as the Geological Survey map, shows. 



Ipswich. Messrs. Pretty's Stay Factory, about 200 yards north of
