the inspector of mines is largely statistical. The supervisor of natural gas 
outlines improvements for the abuses now allowing unnecessary waste of a 
valuable resource. The major portion of the volume is upon the stratig- 
raphy and paleontology of the Cincinnati series. The smaller alternation 
of shale with limestone in the Cincinnati beds is attributed to climatic con- 
ditions while the sudden change of fauna and type of sediment is attrib- 
uted to epeirogenic causes. The Richmond of Indiana is considered the 
time equivalent of the Medina of New York. A complete résumé of the

After a brief description of the physical geography of the state, the

the water-power resources of northern Wisconsin, and the second with those 
of southern Wisconsin. Care 
Waste of Our Fuel Resources. Address of Dr. I. C. WHITE, State 
Geologist of West Virginia, at the Conference on the Conservation 
of Natural Resources, held at the White House on the afternoon 
of May 13, 1908. 
The extent of the large deposits of coal, petroleum, oil, and gas is briefly 
stated. The wanton waste of them is characterized in a forceful manner. 
Our industrial rivals—France, Germany, and Great Britain—have no 
supply of the purest of fuels, natural gas, of which there are wasted in the 
United States 1,000,000,000 cubic feet daily, the equivalent of 1,000,000 
bushels of coal. For every barrel of oil taken from the earth ten times its 
amount has been lost one-half of which may be saved. From 4o per cent. 
to 70 per cent. of the coal is irretrievably lost in mining.
