Peter's house and an clay flow [1] and embanked stream on the upper edge of the "Illinois Fields." The raised edges of the short stream are probably caused, according to N.R.E., by differential elevation due to un- equal freezing and thawing in the ground upon the uneven sur-face of the ice table or upon the surface of the rock floor, which is not deeply buried. We passed the graves of two Danes and three Greenlanders, two of the latter were children of Seck- mann Rosbach, formerly Peters assistant or clerk. On our return route we went to Astrup's monument or cenotaph, a cairn of angular blocks of diabase partly covering a triangular block of the same rock all built so as to face the ice.
