reliable and permanent and of nearer approach to those esthetic ideals which find their beginning in a radical departure from the common-place and ugly equipment which predominates everywhere." Has chapters on sign lighting and color attraction. A wealth of half-tone illustrations. Adapted to the needs of the lay reader.

"An interesting discussion on the different light powers and their uses is given and this section of the book alone will be invaluable to those interested in display lighting. Several color plates have been used to show the highest degree to which effective lighting may be made. The photographs used to illustrate the text are excellent and these, together with drawings and diagrams, make it particularly intelligible."—From a review in the Upholsterer, New York, June 15, 1915, p. 71.

"Mr. Fleming's book is written for the man who is considering the installation of a small pumping plant. He tells him first how much water he should have for the irrigation of the various crops, how large a stream he should have to work economically, and the area which he can irrigate in a ten-hour day with streams of different sizes...all of which the man must know to decide intelligently how large a plant he should have... The book, as a whole, is typical of Mr. Fleming's work as an investigator and a teacher, with which the reviewer has been familiar for years, and shows a very unusual combination of theoretical knowledge and common sense. .”—From a review in Engineering News, New York, June 17, 1915, p. 1174.

"Professor Furman has been very successful in his arrangement of material and treatment of the subject which is especially well adapted to the work of instruction. Numerous problems to be worked out in the drawing room accompany the text, and the method of procedure in each case is logically presented. The introduction of preliminary freehand exercises for drill before taking up the more detailed drafting-room problems is an excellent feature which must appeal to the teacher of machine design."-From a review of the first edition in Engineering News, New York, March 14, 1912, p. 510.

"This work, the original edition of which was published in 1909, is intended as a text-book for engineering students of advanced standing in technical schools. Problems pertaining to practical engineering work are given in abundance. Graphical methods in the solution are used quite as freely as are the methods of analysis. This feature commends the book to working engineers who may be desirous of perfecting their educations by private study. The general flavor of the work, however, stamps it essentially as a class book; and as such, it is a good one." -From a review in the National Engineer, Chicago, June, 1915, p. 328.

The book deals with dynamometry with great thoroughness, giving us an interesting historical sketch of experimental progress, setting forth such theoretical considerations as are required with clearness, and describing the construction and working of practically every apparatus that has been devised for the measurement of mechanical power, including appliances for the laboratory, the test bed, the steamship, and the

This permits the solution of quite involved thermodynamic problems with very little labor or time, although it has necessarily required the expansion of the subject over a considerable number of pages, but it is confidentially believed that the saving of time thus gained in facilitating numerical solutions more than justifies the presentation."-From the preface.
