moor extends over all the Lincolnsliire fens^ and has been traced 
as far as Peterborough^ more than sixty miles to the south of 
Sutton. * * * * There is a subterraneous stratum of decayed 
trees and shrubs, exactly like those we observed at Sutton, at 
Axholme Isle, a tract of ten miles in length by five in breadth.^^ 
Dugdale has noticed the moor in the Isle of Axholme. The order 
of super-position of the alluvial strata is thus^iven by that able g^eo- 
logist, Prof. Phillips, in his Essay on Geology in Lardner^s Cabinet 
Cyclopaedia ; " In some of the old lakes oif Holderness, the same 
mechanical explanation (by warping) appears applicable : an ex- 
ample has been furnished (Waghen in Holderness) which shows 
on the same spot, first, the accumulation of violently agitated 
"Water (diluvium), then a deposit of fine clay and several layers 
of peat, and trees of dififerent kinds ; and over all the stumps of 
Pine (Scotch Pir), which seem to be in their place and attitude 
of growth. 
The same relative position of the alluvium and diluvium oc- 
curs in Marshland (Norfolk), for on reference to the section 
No. 4, afibrded by sinking the well in the town of Lynn, yon 
will find the latter (in stratum No. 5) lies beneath the beds of 
peat and silt ; it is therefore a legitimate inference from the pre- 
mises herein produced, that a similar disposition of the beds of 
peat, silt, and clay exists throughout the level. 
These alluvial beds occupy a lower level than more recent de- 
posits, which circumstance has been attributed to their subsi- 
dence in the course of their desiccation ; for " it is a fact well- 
known near Lynn, that the land which has been regained since 
the Roman sea-banks were made, is on a higher level, and of 
greater value than that which was enclosed by the Eomans ; and 
outside of ' Marsh land^ as this tract is called, the new foreshores 
are sometimes still higher. 
Associated with the peat are subterranean forests consisting 
of the trees indigenous to our island ; they lie buried beneath 
the moor ; the wood, upon exhumation, is generally found to be
