siliceous ferruginous limestone are polished and scratched in various direc- 
tions, and are identical in aspect with pebbles from the Pleistocene boulder 
clays of North America and Europe. The scratched stones were found 
in numbers firmly fixed in the green tillite, in such a condition as to show 
that they had never been disturbed nor subjected to surface abrasion 
since they were imbedded there in early Paleozoic time. 
The promiscuous arrangement of the pebbles, the heterogeneity of 
the mass and of its lithologic components, the subangular shapes of the
