T case directing the inquirer to the source of the abstract where full text of the article may be found. The Digest will aim in no sense to supplant any existing military periodical, but to supplement and render more valuable all of them; positively, by directing the inquirer at once to specific articles desired (often especially when in a foreign language, liable to be inaccessible to many searchers); negatively, by enabling him, by its outline of their scope, to ignore ab initio articles quite out of the range of his investigation."— From the prospectus. 67. *Laubeuf, Alfred Maxime.

"To 'know America first' is a patriotic obligation, but to meet this obligation the railroad traveler needs to have his eyes directed towards the more important or essential things within his field of vision and then to have much that he sees explained by what is unseen in the swift passage of the train... These books are educational in purpose, but the method adopted is to entertain the traveler by making more interesting what he sees from the car window. The plan of the series is to present authoritative information that may enable the reader to realize adequately the scenes and material resources of the region he is traversing, to comprehend correctly the basis of its development, and above all to appreciate keenly the real value of the country he looks out upon, not as so many square miles of territory represented on the map in a railroad folder by meaningless spaces, but rather as land—real estate, if you please-varying widely in present appearance because differing largely in its history, and characterized by even greater variation in values because possessing diversified natural resources... Items of interest in civic development or references to significant epochs in the record of discovery and settlement may be interspersed with explanations of mountain and valley or statements of geologic history. In a broad way the story of the West is a unit, and every chapter should be told in order to meet fully the needs of the tourist who aims to understand all that he sees. To such traveler-reader this series of guidebooks is addressed."- From the preface. 74. *Ibbotson, Fred., and L. AITCHISON. The analysis of nonferrous alloys, by Fred.

Treats each metal in a separate chapter and gives directions for the analyses of the common commercial alloys, such as bronze, brass, white metal, German silver, etc. Reviewed in Metal Industry, New York, Oct., 1915, p. 426; in Journal of the Society of Chemical Industry, London, Sept. 15, 1915, p. 927. 75.

"The importance at the present time of the rare earths and radioactive substances can hardly be over-estimated. Out of their technical utilisation most important industries have recently arisen, the whole subject of gas and electrical lighting has been revolutionised, the match industry has been attacked, while certain branches of surgery and medicine have entirely changed their course within a few years. With the advent of the rarer elements into technology, moreover, has dated the discovery of a whole series of very remarkable steels, which have again reacted on the engineering industries, and on the progress of invention in a way which at present it is difficult to adequately estimate."From the preface. This is a practical, well illustrated treatise dealing less with the pure chemistry of rare earths than with their industrial applications. There are numerous bibliographical and patent references.

(Thaer-Bibliothek.) Author believes that the shutting off of the Belgian and Russian supplies from Germany during the war, and probably afterwards, will offer a good opportunity for farmers to profit in flax raising. The second edition contains an account of all new developments since the publication of the first edition nearly twenty years ago; also gives the results of a recent tour of the author through the flax areas of Silesia and Bohemia. 80. Todd, John A. The world's cotton crops, by John A. Todd... London: A. & C. Black, Ltd., 1915. 460 p. illus. 8°. "The aim of the book is to give, as briefly and comprehensively as possible, an account of the sources of supply of raw cotton, in a form sufficiently nontechnical to be understood alike by the average grower and consumer, so that the former may learn something of the final destination and use of his crop, and at the same time may know what rivals he has in other countries; while the latter may understand the conditions under which his raw material is produced, and be able to estimate the prospects of the future supply from existing fields, or the possibilities of new sources of supply."- From the preface. "Professor Todd gives a very interesting account of these various crops. Though he modestly disclaims any pretension to be a botanist or an agriculturist, he has been for years a keen student of economics. He now occupies the chair in that subject at University College, Nottingham, and before he was appointed to this post he spent five years at the Khedivial School of Law in Cairo at a period when, as he truly remarks, economics and cotton were almost synonymous in Egypt. On this account his description of the Egyptian crops is perhaps somewhat more exhaustive than his treatment of some other countries; but he has visited practically the whole of the American cotton belt, and in all cases he has taken the greatest care to have his work revised and checked by firsthand authorities. The result is a highly interesting and valuable book, which will be recognized as a standard work among those engaged in the multifarious branches of cotton industry."— Journal of the Royal Society of Arts, London, July 30, 1915, p. 819.

Deerfield: published by the authors [at the Montague Press], 1915. illus. 8°. 45 p. A practical and attractive book of directions, with some colored plates exceptionally well done. Includes work both in raffia and in grasses. "The raffia basket in its highest development, as to workmanship, form, design and color, is an expression of true art... Much has been done in copying baskets made by various tribes of Indians. Why shall not we, who have the advantages of a higher civilization, carry into wider fields the work so well begun? The development of the dye industry reveals new possibilities and colors have been created which have never been named. The study of Japanese prints is of great value. Nature has done her part and many a color scheme has been developed from the hills, rivers, clouds and sunsets. She has also provided abundant material with which to work, from her fields and meadows. Shall we not use these opportunities wisely? It is our earnest desire to give some helpful suggestion which prompts us to place these pages before the public, hoping that others may feel such joy in the work as has been ours.' - From the preface. 27 P. illus. 82. *Ayers, S.

Department bulletin. no. 240.) It is only within the last two years that the pasteurization of milk directly in bottles has been practiced on an extensive commercial scale. This interesting document shows that bottle infection may be eliminated, and milk losses saved; that ordinary cardboard caps may be used, and that by using a temperature of 145° F. for 30 minutes, satisfactory bacterial reductions may be effected. 83. *Bock, Otto.
