The primary deposit of Amber is usually assumed to be the blue clay 

 of the M. Oligocene (glauconitic). Thence derived, it is deposited se- 

 condarily in the Samland lignite-beds, also Oligocene ; thirdly, in marine 

 Miocene beds in Schleswig-Holstein ; fourthly, in the widely spread 

 lower Drift, in fossiliferous marls free from shingle, which is the chief 

 source, as this division extends from E. Mecklenburg to the Danish 

 Islands and Windschoten in Holland ; the yield is estimated at 1 lb. per 

 square metre of surface. It is redeposited, fifthly, in the boulder beds 

 (of Northern origin) over N. Germany, being in divisions of Glacial drift 

 which consist of sand, loam, gravel, &c. with erratics ; amber is found 

 in this from the Russian border to HoUand. Sixthly, it is found on the 

 sands between tides, thrown up by the waves and washed out of the 

 coast-alluvium or marsh-formation, which, again, was formed by the 

 elutriating action of the sea on the materials of the Drift. E. B. T.
