Excerpt from Formation of Coal Beds It is almost invidious to express obligations to any apart from all, for the experience has proved anew that geologists are a whole souled race. Assistance has been rendered freely and. Without reserve, not only by those who have shown friendship and confi dence during many years, but also by those, in this and other lands, to whom the writer is only a name. But it is impossible to avoid expressing earnest thanks to I. C. White, D. White and C. Barrois, who, by timely suggestions, removed serious perplexities and thereby added to an already great debt, which cannot be paid and can receive only gratitude as interest. At the same time, it must be remem bered that these students are in no wise responsible for the writer's conclusions, which in some cases are notably at variance with theirs.
