Earliest concrete pavement of reliable record was laid in Bellefontaine, O., during 1893 and 1894, containing 4,400 square yards. It is estimated that throughout the United States during 1915 over 19,000,000 square yards were constructed. This interesting, well-illustrated document gives practical directions, at the same time pointing out the advantages and disadvantages of this type of road.

Gives costs and a typical specification.

Although of comparatively high first cost, properly constructed pavements of this type are durable under practically all traffic conditions, affording easy traction and moderately good foothold for horses, and are easily maintained and kept clean. This well-illustrated document tells how the bricks are made and how the pavement is laid. Appendix contains typical specifications.

It is a nontechnical presentation of the problems of the track foreman and supervisor in the laying of tracks and switches, written largely from the author's own experience as track laborer and foreman. At the same time the author expresses the belief that the book will be useful to the young engineer in charge of track work, and the reviewer fully agrees with this opinion...

"This little book of problems was prepared to be used in conjunction with
Morecroft's elementary text-book on Continuous and Alternating Current Machinery
as texts for a short course given by the author to civil and mining engineers.
It is well understood that the average student is apt to find general principles
and mathematical formulae somewhat vague and uninviting, unless his concep-
tion is made somewhat easier by the way of concrete examples and laboratory
work. The author believes that Morecroft's text-book, Clewell's Laboratory Man-
ual and this little book of problems make a very effective combination for admin-
istering a short elementary course to advanced students in non-electrical en-
gineering courses... In general the problems are very closely related to
engineering practice and are so made up as not to be mere mathematical puzzles."

"There are few authors better qualified to deal with dynamo design than
Professor Miles Walker, who is not only personally responsible for much prog-
ress in the subject, but is a clear writer and an original thinker. This originality
is shown in the planning of the book, which does not profess to be a complete
treatise on the design of every kind of dynamo-electric machinery, but handles
the subject in a way that we do not remember having seen attempted before.
Addressing himself as much to the consulting engineer as to the designer, he
makes the main part of the work the second part, in which, after a few words
as to the drawing up of specifications in general, he gives a series of some
eighteen model specifications for A. C. and D. C. plant, including generators
(both engine and turbine driven), motors, rotary converters, boosters, phase
advancers, etc., all worth detailed study by those responsible for central station
design and extension. Each one of these specifications is followed by a complete
working out of the data of a machine to comply with the specification, following

exactly the methods that might be adopted in an actual designing office... The industry and the profession of electrical engineering are distinctly_the richer by the possession of such a book."— Electrical Engineering, London, Sept. 30, 1915, p. 396.

Practical, carefully written, and encyclopaedic treatise by the well known professor of engineering at the City and Guilds Engineering College, London. Scientific in scope, typical apparatus is described to illustrate the general technical principles, no attempt having been made to supply knowledge of all concrete designs. Its 760 pages cover a general discussion of the steam plant, with special chapters on boilers and heating circuits; motive power circuits; performance and losses; condensing plants; energy diagrams for simple and compound locomotives; dynamics of the steam engine; train motion and energy requirements; engine balancing; valves and valve-gears; steam flow; and steam turbines. Well supplied with diagrams, tables, and many practical problems. Decidedly an important work.

"The book is well arranged, with the parts in logical sequence. It is well written. The diction is always clear and unambiguous, and it is usually concise. When there is departure from the latter high quality it may be attributed to anxiety to avoid the barest possibility of misunderstanding. There is here apparent the style of the conscientious lecturer who is determined that not the dullest of his students shall have the smallest excuse for mistaking his plain meaning."
