To quickly assess the difficulty of the text, read a short excerpt:
It is a matter of common knowledge that the valuable ores, minerals, rocks, fuels, etc. , are not uniformly distributed in nature, nor, on the other hand, do they occur with entire irregularity, or as though by mere chance. The experience of men all over the world, when brought together, shows certain relationships between the occurrences of these ma- terials and the occurrence of other materials, or of other conditions and forces. These facts, when all brought together, make up the science of ...geology. When, for example, the geologist draws a line around a certain area in the Cumberland Mountains and says, " Within this line there is, or may be, bituminous coal, but outside of it there is none, " he bases his statement on a whole volume of " theoretical " informa- tion. Thus it implies that he knows the age of the rocks within that line and of all the rocks outside of that line, involving in turn an intimate knowledge of the fossils in these rocks through which their age is determined, and the general meaning and relations of these fossils.
