 her Sernander sammenstiller »Lower forestian« med » Boreal« - 

 og »i4/JC(//«s«-tid, er kun, hvad Geikie allerede tidligere hadde 

 gjort (Smithsonian Report 1898 (1900), pag. 345). Den efterføl- 

 gende lid skildres af Geikie paa følgende maate: — »Evenlually, 

 however, submergence ensued — — — it is notable that the 

 character of the marine fauna which at this stage lived off the 

 coasts of Scandinavia and Britain is indicalive of more genial 

 condilions than now obtain. The climate, however, gradually 

 became colder, the verlical and horizontal range of the forests 

 was restricted, and snow flelds again appeared among Ihe higher 

 mountains of our Islands. In Scolland glaciers here and there 

 came down lo the sea, and dropped their moraines upon the 

 beaches there forming; the large majority, however, terminated 

 inlan(l< (L. c. pag. 345). Og videre fortsætter han: »Later cli- 

 malic oscillations foUowed, but on a decidedly reduced scale. 

 The etfecl of these was, naturally enough, most marked in north- 

 western Europe, decreasing gradually southward, and doubtless 

 evenlually fading away in the lower latitudes of the conlinent« 

 (L. c. pag. 34(j'. »The local glaciers of the British Mounlains, 

 some of which, as I have said, actually enlered Ihe sea, al last 

 began to relreat. The climate became more genial, and so once 

 more favored the growth of foresis, which in many piaces began 

 lo overspread Ihe now dry peat bogs, benealh which Ihe trees 

 of Ihc carlier foresl cpoch lay enlombed. Evenlually, however, 

 colder and more humid condilions relurned, and small glaciers 

 appeared in a few piaces among the lofliesl heighls of Ihe Scot- 

 tish Highlands The foresis now, as before, began to 



decay in many |)laces, and the bog moss and ils allies again 

 exlended in all direclions, and so, evenlually, a second forest 

 bed became enlombed in growing peal. Il is needless lo say
