What reading level is First And Second Annual Report of Progress By the State Geologist And the Assist book?
To quickly assess the difficulty of the text, read a short excerpt:
Tolerably pure limestone contains twelve per cent, dolomite about thirteen per cent of pure coal ; every hundred feet of limestone contains enough of pure coal to form a bank of anthracite of ten to twelve feet in thickness. But all of this combustible, both metalic and carbon- aceous, is now unavailable, since these elements are in the rock, combined with oxygen ; that is they are burnt. The only exception to this rule is the coal ; for this reason it has so great economic value.
The coal havi...ng been at length considered in the first chapter, I REPORT OF STATE GEOLOGIST. 241 may here limit myself to the calcareous rocks of the State. Neither the arenaceous nor the argillaceous rocks have as yet been analyzed.
THE CALCAREOUS ROCKS OF IOWA.
The results of chemical analysis of these rocks, are usually stated by the per centage of each of the proximate chemical com- pounds contained in the same. But it is impossible even for an expert to get a really precise idea of the constitution of such a rock by the full, unreduced result of the analysis.
