nated everywhere at the surface, but the boulders of the deeper 

 drift were fine and coarse quartzite, gray granite, gneiss, syenite, 

 dyorite, and limestone. Many of the last contained Fusulinas, and 

 much resembled the Upper Coal Measure limestones. Many of 

 the boulders, including the limestone boulders, were planed and 

 striated. The great age of this moraine, possibly a million years, 

 was shown by the fact that the surface boulders were all fine- 

 grained quartzite, while the protected ones were of mixed species. 

 Even the coarse quartzite, where exposed, was badly weathered. 

 The boulders of the deeper drift were common archsean species, 

 and, according to all indications, were brought to Kansas by the 

 same ice movement which brought the quartzite. The Kansas 

 glacier may have picked up the granite, etc., in northern or central 

 Minnesota, the quartzite in southwestern Minnesota or eastern 

 South Dakota, and the limestone in northern Kansas. 



Professor Popenoe showed us what seems to be the pseudomorph 

 of the end of a huge calcite crystal consisting of basalt. Molds of 

 similar crystals in great masses of copper from the copper mines 

 near the western end of Lake Superior were on exhibition at the 

 World's Fair at Chicago. This pseudomorph may have come in 

 the Kansas glacier from that locality near Lake Superior.
