the Transactions, Vol. xv, page 351-368, with fifteen lithographic 
plates; one of these represents the rock recess with the railroad 
track running in front of it. The text accompanying the plates 
contains a statement concerning the probable age of the relics; 
thirty inches of black mold accumulated by decaying vegetation 
would seem to indicate to the author a time roughly estimated at

in the production of those physical changes which separate the 
deposits containing the remains of palzocosmic man from those 
of later date. The paper appears in full in the Kansas City Re-
