(This sample was taken because we took a sample of ground-water' pt the 
same place, SE. % sec. 23 T. 38 N , R. 8 E. The incrustation as gathered 
yielded 7.4 prcent of its weight to water.)

A sample of the soil and subsoil was also taken at this place. 
The series of analyses thus presents as complete a set of analytical 
data as we can present from the chemical standpoint.
