Many of the generalizations on the great events of geologic history 

 apply to a much larger area than that named in the title of the report.

Peat Resources of Wisconsin. By F. W. Huels. Wisconsin Geol. 

 Survey, Bull. 45, 1916. Pp. 274, figs. 20, pis. 22. 



As neither oil, natural gas, nor coal is found in this state, special 

 interest attaches to its peat deposits, and has resulted in their system- 

 atic examination. Part I contains a general discussion of the origin 

 of peat, its preparation and uses. Part II gives a description of the 

 state's peat deposits. These are limited to the drift-covered area. The 

 quantity of peat land is placed between two and three million acres and 

 the amount of peat between two and three billion tons. Analyses show 

 that for the most part the peat compares favorably in quality with peats 

 now being used extensively in Europe. 



A number of companies have engaged in peat production but all 

 have suspended operations. It seems probable that the greater part 

 of the peat lands will be drained and reclaimed for agricultural purposes.

Soils of Mississippi. By E. N. Lowe. Mississippi Geol. Survey. 

 Pp. 220, figs. 22. 

 This is a preliminary dicussion of the subject and is to be followed 

 later by a complete report. The state is divided into 9 soil areas that 

 correspond roughly to physiographic provinces. The soil of chief 

 geologic interest is found in a belt of loess, that extends the length of the 

 state, and borders the Mississippi River flood plain. 



An appendix to the report contains a number of soil analyses.

Hudson Bay Basins and Upper Mississippi River. U.S. Geol. 

 Survey, Water-Supply Paper, 355, 1915. 

 This volume is one of a series of twelve reports of measurements of 

 stream flow in the United States during 1913. The data cover the flow 

 of the larger streams in Minnesota draining into Hudson Bay and those 

 of Minnesota and Wisconsin that are tributary to the Mississippi.
