374 THE ILLINOIS GLACIAL LOBE. 



This till tract fronts the south border of a swamp for 2 or 3 miles. 

 The till extends back but a short distance toward the south, soon giving 

 place to sand. 



A very small tract underlain by till is found near the corner of sees. 14, 

 15, 22, and 23 of this township (Bainbridge). It is less than a square mile 

 in extent. A well in the southwestern corner of sec. 14 penetrates:

A mile west from here, at Bainbridge Center, wells are almost entirely 

 in sand to a depth of 60 f eet. In the sand are thin beds of slightly 

 cemented gravel. This sandy tract extends west a mile or more from Bain- 

 bridge Center and nearly as far north. A well in the western part of sec. 

 10, on the farm of A. Woodruff, penetrates:

A well across the road, 75 feet in depth, has a similar section. 



In western Bainbridge and eastern Benton townships (Ts. 4 S., R. 17 

 "W., and 4 S., R. 18 W.) wells vary much in the character of their section, 

 some being almost wholly in till, others penetrating little beside gravel and 

 sand, and this is often true where the whole surface appears sandy. 



In the northeastern part of Bainbridge Township, about 3 miles due 

 south of AVatervliet, are three flowing wells. They are only 16, 28, and 

 40 feet deep. Most of their section is in blue-gTay till, and the water 

 comes, it is said, from caverns in the clay. The water, which is quite 

 chalybeate, rises 2 to 4 feet above the surface. 



In the portion of the Valparaiso moraine in Berrien County south from 

 the latitude of St. Joseph, Michigan, no records of wells were collected. 

 The portion east from St. Joseph River apparently consists largely of sand.
