Results of 36 Hesemann counts held in the Northern part of the Netherlands are reported. They confirm previous counts in this area, namely the occurrence of distinctly different assemblages of erratic boulders, while on the other hand mutually similar associations are sometimes spread out over tens of kilometres. In a few places crystalline indicator boulders are found in stringers as well as floelike masses of till of a type different from those in their immediate vicinity. The erratic boulder counts are considered to be of little chronostratigraphic value and have local significance only. Some kilometres South of Norg two parts of a glacial erratic boulder were found separately in ground moraine. Both had been transported by inland ice, one part one kilometre away from the other along a line N 15° W – S 15° E. Previously an identical propulsion direction of the inland ice in this area was assumed on geomorphological grounds.
