In 1893 he collected the most important and interesting of his scientific lectures and addresses into a volume to which he gave the title _Fragments of Earth Lore_. The book was published by his friend Dr Bartholomew of the Edinburgh Geographical Institute, and served to introduce the results of some of his researches to a wider circle of readers than they would otherwise have reached, as they had originally appeared in publications as widely different in purpose as _Good Words_ and the _Transactions of the Geological Society of Edinburgh_. Most of the papers, as was to be expected, treat of the progress of glacial geology, and one of these is of special importance. It is entitled “The Glacial Succession in Europe,” and was reprinted from the _Transactions of the Royal Society of Edinburgh_. It shows considerable progress along the lines which his work on glacial and interglacial periods had previously followed, and was the precursor of the third edition of _The Great Ice Age_, in which the new developments of this branch of science were to be more fully expounded. Among the other papers are several which are excellent popular scientific articles, such as the sketch of the “Geology of the Cheviot Hills,” originally issued in _Good Words_ in 1876. These essays show him at his best as an exponent of the simpler and more attractive themes of geological literature. He had an easy, fluent style, and had he chosen to do so, might have attained great popularity as an exponent of science for the million. The fine illustrations of this book deserve special mention, especially the maps, which owe much to the skill and artistic taste of Dr Bartholomew, who in this matter had the cordial support and co-operation of Prof. Geikie. Ever since his days on the Geological Survey he had set a very high standard in the preparation of maps, and paid the greatest attention to their artistic qualities as well as to their excellence as scientific documents.
