A RECORD OF TIME 79 



tion, for it showed that the vertebrates lived in this 

 warm era between the ages of ice* The treasure 

 was sent to Washington for identification, but was 

 unfortunately lost* The broken story was resumed 

 by the discovery of part of an Elk's antler* showing 

 that not only the lower vertebrates but land mammals 

 lived in this region between the glacial periods* 



This scene of fertility and active animal life is 

 covered up with another immense bed of boulder 

 clay* revealing the slow intensity of another accumu- 

 lated continent of ice* Again the fragments of rock 

 are worn round and smooth* and imbedded in the 

 clay the slow deposit of ages* But this second 

 continent of ice obeyed the perpetual law of change* 

 and above the bed of boulder clay that records its 

 existence are the changing deposits and the water- 

 washed sand and gravel of the bottom of the lake that 

 covered the land where this city now stands* Again 

 come the evidences of marine life* shells and other 

 remains being modern and easily identified. Con- 

 templating that record of inconceivable time, the 

 transient growth of Oak, Pine, and Birch on the top 

 of the hill seems as presumptuous as man's usurping 

 institutions* But a few years few as time is recorded 

 in that cavernous pit and excavated hill and the 

 continent may sleep again in the long oblivion of a 

 glacial era*
