It was Forchhammer who was the first to propose to look for a statistical evaluation of the erratic boulders within the Quaternary moraines of Northern Germany and Denmark. However, between these early remark in the year 1843 and the first boulder countings of J. Korn (in Schroeder & Stoller 1905, 1909), followed by V. Milthers ( 1909), there was the precocious and mislead period of Nordic Glaciation explanations, long before polyglacialistic ideas appeared, and it is from Hesemanns (1930 a.s.o) work only to talk about suitable statistics, which were complemented by the publications of van der Lijn (1932) and K. Richter (1933 a.s.o.). From the middle of this century on, boulder statistics began to be practized in almost all of the distributional areas of sediments of the Northern European Glaciations, from the Netherlands in the West up to Poland in the East. It is a method of supporting value of course, but it is only possible to make use of it for lithostrati-graphical questions and correlations if – a reliable framework of samples exists, which have been calibrated by biostratigraphical determination, – the statistical comparisons have been restricted to a region of reliable size, – the statistics is supported by other findings like lithological, petrographical, facial observations. This is so, because Quaternary Stratigraphy is a part of geosciences which is needing a multiple classification system and cannot be developed by one single method only. In this sense erratic boulder statistics' specialists are understanding their work as one approach amongst various others.
