A well in the southwestern part of the same section, 103 feet in depth, 

 penetrates only 8 feet of till, the remainder being sand. 



A well in the northeastern part of sec. 20 of the same township, 80 

 feet in depth, penetrates but 7 feet of till. The sand is coarse at top and 

 becomes finer below. In the lower part of the bed it was fine as flour. 

 The pipe was drawn up to within 57 feet of the surface, where the sand 

 was sufficiently coarse to be screened by the pump strainer. Several other 

 wells in the southwestern part of Lawrence Township are characterized by 

 a slight depth of yellow till underlain by a great depth of sand.
