Such is indeed the General opinion. This proposal seems tobased conventional geological classification. The Silurian system,Devonian system, the Carboniferous system are represented in our books asgroups of formations which everywhere follow one another in this order fromwhich each separately is the same everywhere the antiquity. Although, maybenot saying that this number of systems is widespread, however, the assumptionthis, apparently, is accepted as correct. In North and South America, Asia,in Australia, the series of layers added to one or the other of these groups, and onefrom the reasons adduced to justify this reckoning isthey are known for mineral signs, and lying on each other inknown order. Although, in all probability no informed geologist notwould argue that the European classification of strata is applicable to allthe globe, however, all geologists or at least most of themI write so, as if really it were so. Between the readersgeological books nine-tenths render the impression that the division of systemsprimary, secondary, and tertiary is absolute, unchanging application,these large rasklineny division into smaller units, of whicheach dramatically different from all others, and everywhere can be parsable byknown, inherent characteristics, and that in all parts of the globe thesethe secondary system began and ended each with his hand in one andthe same period. Every time they meet with the expression "coalera", they understand it in the sense that it was the Carboniferous erafor the whole Earth that, as the right says Hugh Miller, it was the epoch whenthe whole Earth was covered with vegetation, much more luxurious than insubsequent periods; and if anyone of these gentlemen in one of ourthe colonies met the layer of coal, he would have taken as agiven that the layer of this modern Carboniferous strata of England.
