To quickly assess the difficulty of the text, read a short excerpt:

The con- structive agencies which recorded the passing of the millenniums in- volved in those periods, were as active and extended as the agencies whose work has been recorded in the rock strata underlying the prairies of San- gamon county.
ORIGIN OF THE EOCKS.
None of the rocks in Sangamon county were formed by fire as were many rocks in mountain regions. Either wind or water were the agents active in their construction. The water in which they were deposited was cold, sometimes salty, other t
...imes fresh. Sometimes it flowed in a river of water or of ice. At other times it constituted a lake or an ocean. The kind of rock and the fossil remains contained therein lead to such a conclusion. Sandstone, shale and limestone are the only kind of rocks native to the county. The sandstones were formed along shores of great lakes or oceans, as they are being formed today when waves and winds carry away soluble or light material from the debris of the coast, leaving the heavier and insoluble substances, usually particles of quartz, sorted according to size.
