MISCELLANEOUS NOTES AND OBSERVATIONS. 
“Post Glacial” Faults on the East Coast. — In a short paper 
Mr. Longe brought before the notice of the Society certain dis- 
locations or faults in the strata exposed in the cliffs of the East 
Coast, which he 'regarded as effects produced by lateral pressure 
after the deposition of the Chalky Boulder Clay. He used the 
term “faults” in its most comprehensive sense, and the term 
“post glacial” in accordance with the general usage of geologists 
without implying his adoption of the glacialists’ theory that the 
Chalky Boulder Clay of East Anglia is in any way a glacial 
production. 
He noticed first the effects of lateral pressure exhibited at 
Lowestoft — and referred to a pamphlet entitled, “ Did the 
Waveney ever reach the Sea via Lowestoft?” wvitten some 
years ago by Mr. Edwards, the engineer of the harbour works 
undertaken in 1821 . 
In cutting through the narrow isthmus which separated Lake 
Lothing from the sea, Mr. Edwards met with a mass of Chalky 
Boulder Clay some way below the surface, and under this a bed 
of sand of the depth of thirty feet, which he identified as the same 
deposit of sand as that comprised in the cliffs on either side of the 
valley, and in some pits inland, known by geologists as the 
“ Middle Glacial.” 
The position of this bed of sand below the sea level, could only 
be explained by its having been dropped down by a sort of “trough 
fault ” — during the process of elevation by which these parts w'ere 
raised to their present height after their submergence in Pleistocene 
times. Evidence of coast disturbance in the immediate neighbour- 
hood of the harbour was furnished bv the discovers of a larye 
mass of chalky loam intruded into the sands of the cliff, about 
half-a-mile to the south (nearly opposite the present Empire Hotel).
