REPORTS. 



by the Members of this Section with the exception of the 



examination of peat deposits, 

 which, in consequence of the 

 clearness of coal, are being 

 utilised. 



The localities examined are : 

 Two openings at Vazon and one 

 at the Foulon. 



That at the Foulon may be 

 classed as a marsh peat deposit, J 

 the period being so far unde- 

 termined. The deposit is of 

 moderate depth (6 feet about), 

 consist of marsh plants and, as 

 far as we at present know, show 

 an absence of large trees. 



Owing to silting up of the 

 natural drainage of the valleys 

 to the west, the low lands ex- 

 tending from the Rohais to 

 Cobo became marshes, the last 

 parts being Mare de Carteret 

 and Grande Mare. Thus the 

 whole district so described must, 

 at one time and probably for 

 many hundreds of years, have 4*. 

 been composed of dangerous 

 bogs, and no doubt in many 

 places there are good deposits 

 of peat which should contain 

 the bones of animals and men 

 of the late Neolithic period. 



The drainage of the Talbot 

 Valley as well as the deposit of 

 marine sand produced a similar 

 result at the Grande Mare, the 

 peat of which extends under 

 the whole of the flat surface 

 where free from rock out-crops 

 — but there is this difference, 

 the lower portion of the Vazon 

 Peat is submerged forest, 

 whereas at the base of the 

 Castel hills, as far as known, 

 only marsh peat exists.
