SOUTHERNMOST KANSAS TILLS 379 
I 
Kansas River is according to Todd in the vicinity of Linwood 
and Lenape.® Opportunity presented itself later for a detailed 
investigation of several of these deposits. The exposures, which 
are all in Douglas County and from three to seven miles south of 
Eudora, are interpreted by the writer as being till. 
The three chief outcrops, all of which are in road-cuts, are 
located as follows: 
(1) . SW. cor. NW. % Sec. 21, R. 21 E., T. 13 S. 
(2) . SW. cor. Sec. 9, R. 21 E., T. 14 S. 
(3) . mile east of exposure (2).

The material at these places is exposed in road-cuts from 100 
to 200 feet long and about three feet deep. In all cases the drift 
is composed of a brown, more or less sandy, often sticky clay 
material, thoroughly leached and containing numerous pebbles 
and boulders. Some stratification is at places in evidence. The 
coarse materials consist chiefly of red quartzites, well-decayed 
granites, brown to white cherts, gneisses, schists and sandstones. 
In size, the pebbles average less than one half of an inch in
