16 LIFE OF THE PLEISTOCENE 



as known to the writer, these are the only places along the entire length of the 

 upper beach where molluscan shells have been reported, and none have been 

 personally found, though search has been made for them in several exposures 

 and excavations. There appears, therefore, to have been a great scarcity of 

 molluscan life in this stage of Lake Chicago. " The deposit spoken of above 

 should probably be referred to the Toleston stage, as herein understood, and 

 not to the Glenwood stage. This marsh was probably a long, narrow bay, 

 occupying the territory now drained by the Galien River. 



Interval of Emergence {page 440) 

 A low water Post-Glenwood stage is recognized, the data presented in a 

 previous paper (1897) being repeated. 



Calumet Stage {page 444) 

 The statement of 1897 is repeated. 



Second Emergence {page 446) 

 A second period of emergence (possibly preceding the Algonquin Lake 

 stage) is recognized. 



Toleston Stage {page 450) 

 The information contained in the previous paper is repeated. 

 1902. alden. 23 — In the Chicago Folio, Alden repeats the statements made 

 in the Bulletin of the Chicago Geographic Society (1899). 



1905. Anderson. 24 — In this paper, attention is called to the finding of 

 proboscidian fossils in Cook County. 



"Evanston. — The tooth of a mammoth was taken from a gravel pit near 

 Evanston. It was placed in the museum of the Northwestern University. 

 (Reported by Prof. U. S. Grant, Northwestern University) 



"Glencoe. — A fragment of a mastodon tooth four and three-fourths inches 

 long was dug up by Mr. James Robertson while ditching in glacial drift at 

 Glencoe. The fragment, which was from the proximal end, is now in the 

 possession of Mr. Walter O'Neill of Lake Forest. 

 (Reported by Prof. James G. Needham, formerly of Lake Forest College) 



1906. goldthwait 25 (page 420) calls attention to the shells found by Dr. 

 Marcy and others in the Toleston beach at Evanston, remarking that the 

 presence of these mollusks indicates a lake with less frigid waters than during 

 the Calumet or Glenwood stages. 



1907. goldthwait 26 (page 118) mentions the presence of life in the Toleston 

 beach at Evanston, and says, "In the deposits of the 24-foot beach at Evanston,
