the second uppermost layer of the Sphagnum peat (II); as mentioned mi p. 

 142 it was a single carbonized nut which was found in this laver; it does 

 not seem unreasonable to conclude that it has been preserved just because 

 it was carbonized — just as it seems to me, that the discovery of Carpinus 

 in this layer Lndicates that considerable lavers of the uppermost parts of the 

 bog have been eroded away. 



Above has been noted the considerable lloristic difference between the 

 interglacial Brørup bog and our postglacial bogs; the or der in which the 

 (•(million species have wandered in or settled down in the bogs seems 

 however on the whole the same: first the aspen and birch, then firs and 

 later oak — even if it is not possible in the Brørup bog to distinguish the 

 separate zones of forest trees so sharply as in many postglacial bogs. 



Naturally a single section in a single bog can only give indications but 

 no certain proofs; for these we require much more extensive investiga- 

 tions. But the result of the investigation of this bog section is however quite 

 striking and agrees so remarkably well with the results of my studies on 

 other interglacial deposits — espccially with the Ejstrup section (see below) 

 — and also agrees so exactly with the corresponding investigations of Weber 

 and others in North Germany, that this correspondence cannot depend upon 

 mere chance occurrences. On the contrary, it is a link in what I would call 

 the biolog i cal or p alæ on t ol o g i c a 1 evidence for the inter- 

 glacial a g e o f t h e b o g. 



Bog on Tuesbol Common. 



(Mose paa Tuesbol Mark.) 



During the years 1.S98— 1907 I undertook a number of excavations, de- 



scribed on pp. 1(50— 171, in a bog on Tuesbol Common, ea. 2 Km. north-west 

 of Brorup Station (the place is marked on the map lig. 11 with a cross and 

 3); in the tables pp. 174—177 a list is given of the animals and piants found 

 in this bog. Of special interest is the discovery of Dulichium sjxttlmceum 

 Pers., partly in the Sphagnum peat (in borings I and II), partly in gytje 

 (borings IV and V) — as also the seed of Brasenia purpurea Mich. 



The bog is covered by 1 — 2 m. of sand with stones. 



Similar bogs were found at Skovlyst near Brorup, at Hulkjær waler-mill, 

 at Lervad and Bramminge as also at several piaces in the neighbourbood of 

 Brorup; they were covered by 1—4 m. of sand and contained a similar flora 

 to that described in detail found in the bogs at Brorup Station town and on 

 Tuesbol Common. 



Bog at Hollund Sogaard. 



(Mose ved Hollund Sogaard.) 



In 1903 excavations were made in an interglacial bog ca. 16 Km. north 

 of Brorup (cf. figs. 21 and 22, pp. 195 and 197) : 



0.5 — 0.75 m. sand with few and small, sand-rubbed stones. 



coarse sand.
