Rh establish a connection between the Kindergarten and the public schools. The present book is the first fruits of his efforts in this direction, and aims to make the principles of Froebel applicable to primary schools.

author expresses a considerable degree of satisfaction at the manner in which his work in the survey of these mountains has been accomplished. He had his own way in conducting it, and pursued it under circumstances of exceptional advantage, with the result that, he says, "so thorough was the display [of the formations], and so satisfactory the examination, that, in preparing my report, I have felt less than ever before the desire to revisit the field and prove my conclusions by more extended observation." The Henry Mountains are not a range, and have no trend, but are simply a group of five individual mountains, separated by low passes, and-without discernible system of arrangement, situated in Southern Utah, on the right bank of the Colorado River of the West, and between its tributaries, the Fremont and the Escalente. The highest peaks rise about 5,000 feet above the plateau at their base, and 11,000 feet above the level of the ocean. At the time of their discovery by Professor Powell they were in the center of the largest unexplored district in the United States; and they are in a desert country that has hardly any economic value.

This work forms one of the series of the "Catalogue of the Library of Harvard University," and is one of the first formal attempts to collect separately the titles of papers on fossil insects. It shows the results of great labor, for it gives not only the titles of books and papers on the subject, but also a very large number of references to works and essays in which fossil insects are only referred to, or form one among other topics of equal prominence, which are touched upon in the course of a chapter, essay, or book, and in all the principal languages of science. Except when otherwise stated, all the papers quoted have been examined by the author personally.

object of this work is to furnish tables by means of which students may, with as few easy tests as possible, learn to determine and classify minerals found in the United States, and become familiar with their principal characteristics. Two tables serve for the determination of species; a third gives the crystalline structure and other distinctive characteristics of each species; a fourth classifies the species according to "Dana's Mineralogy"; and a fifth classifies by basic elements and ores. The appendix gives the distinctions between some of the closely allied species and varieties. A great deal of information is compressed into a small space.
