68 STEVENSON— INTERRELATIONS OF THE FOSSIL FUELS. 



ing: (i) Diluvial sand, 2 to 2.5 meters; (2) carbonaceous clay, 1.2 

 meter; (3) brown coal, peat-like, i meter to 3 decimeters; (4) clay 

 marl, 3 to 3.5 meters; (5) peat, 45 centimeters; the upper part is 

 Aloostorf with seeds and reeds, while the lower portion has leaves, 

 wood, seeds, rhizomes of Nymphcca; (6) Lebertorf with diatoms, 

 I.I meter. 



The Lebertorf is a lens-like deposit and is replaced in the southern 

 part of the excavation by a meter of sand. Keilhack could not 

 determine the age of the beds and maintained that the matter could 

 be determined only by a boring. A. Nehring, in the discussion, held 

 that the deposit is interglacial and probably equivalent in age to the 

 Schieferkohle of Utznach and Diirnten. Credner*^ visited the same 

 locality and obtained a section, evidently from another portion of 

 the excavation. The peat is a single bed with maximum of a meter 

 and a half. Number 4 of Keilhack's section being absent. The 

 Lebertorf rests on clayey marl overlying sand. He thinks that the 

 peat is post-glacial. In the following year, Potonie^*^ summed up con- 

 clusions presented by H. Credner, H. Keilhack, A. Nehring as well 

 as by other observers and discussed in detail the relations of the 

 flora found in the Klinge deposits. This is distinctly diluvial. The 

 succession is that of so many peat-filled basins, Lebertorf below, 

 succeeded by peat in which are many erect rooted stumps, clearly 

 in situ. The compression, due to weight of the overlying deposit, 

 had so changed the appearance that Keilhack thought it brown coal 

 with peat-like features, while Credner preferred to call it peat with 

 resemblance to brown coal. 



Weber^' described two interglacial peat deposits, exposed during 

 excavation of a canal from the Elbe to the Eider. One, seen where 

 the canal emerges upon the Eider lowland, is exposed for more than 

 1,600 feet. The underlying material varies. The bed is in two 

 divisions separated by sand ; the upper one has suffered much from 

 disturbance and is broken up badly, while the lower one is practically
