This characteristic feature of "Expamet" ensures an even distribution of stress throughout the con- crete work; as all the strands or mem- bers are connected rigidly, they cannot be displaced by the laying and tamp- ing of the concrete. Moreover, the concrete within the meshes is brought into compression under loading conditions; thus the value of the reinforcement is increased and there is found a rational ex- planation of the great strength of "Expamet "-Concrete construction.

Volume I deals with the services of Military Engineers in India from the purely military point of view; it traces this history of the old Bengal, Bombay and Madras Engineers and subsequently of the Royal Engineers in India, and of the three Corps of Sappers and Miners; it records their exploits in war and their military achievements in peace. Volume II deals with their work on the civil side and records their services in all spheres of civil engineering, showing the extent to which practically every branch owed its inception to military engineers; it also relates their activities in the Royal Mints, Survey, geology and civil administration. A few of the many appreciations of Volume I received:- The Mlorning Post, Ioth October, I933. .There is a remarkable freshness and originality in what might be termed the pioneer work that was being done in India during the two centuries previous to the Mutiny. Much of it, indeed, was of far greater OPINIONS OF THE PRESS. "In such times as this, a work at such a cost is as marvellous as the book is admirable. Parents of lads entering their teens-the doubting stage-should make a point of placing a copy in their hands."-Daily Mail, 26th January, I920. " Really excellent little work."-Daily News, 26th Sept., 1902. "We welcome a new edition.... The appeal of the book is evidently one to common sense, and the success it has met is fully deserved. There is a healthy lay atmosphere about Col. Turton's arguments which renders them we fancy peculiarly effective."-Pall Mall Gazette, IIth March, 1907. "It is difficult to know whether to admire most the logical precision with which he marshals his facts and enforces his conclusions, or the charming candour, and freshness of style, which makes his book so readable."-Liverpool Daily Post, I4th March, I907. " This is a new edition, thoroughly revised, of Lt.-Col. Turton's famous book.... We are specially struck with the detached manner in which he examines the case, he holds the scales evenly and is not rhetorical. Any one who has any power of reasoning at all can follow him clearly from start to finish."-Bristol Times and Mirror, I8th Feb., I907. "It is a book for the hour, and needs to be circulated by thousands... straightforward, manly, and convincing."-School- master, 27 th March, Igo9. " This well-reasoned work appeals to common sense, it is candid and convincing."-Labour News, I6th Jan., 1925. Church of England. "Nothing need be added to our previous commendations of a work which has proved singularly serviceable, except to remark with approbation that its price has been lowered."-Chitrch Times, 12th Dec., 19I9. " If you want a simple book of Christian Apologetics, get Turton's ' The Truth of Christianity.' "-Church Times, 7th April, 1933. " We have repeatedly expressed our sense of the merit of Col. Turton's book."-Guardian, 9th Dec., 90o8. ... " It deserves to be pointed out in more than a word, that every new edition is really such in a special degree. Col. Turton seems to devote the greater part of his leisure to the perfecting of his work, and never to be satisfied. Thus a thought is developed here, an argument strengthened there, and fresh illustrations are added as one edition succeeds another."-English Churchmlan, I2th Dec., I912. " The present edition has again been carefully revised throughout, and full use has been made of the most recent developments of scientific knowledge. The valuable character of Lt.-Col. Turton's work is now so well known that it requires little recommendation." -Record, gth Oct., I93I. " There is no padding and no unnecessary rhetoric. All the available space is filled with good solid reasoning, put in simple language which an intelligent artisan can follow as easily as an educated person."-Chlurch Family Newspaper, 3rd Oct., 1902. " Few works of Christian apologetic have proved so useful.... All the argument is lucid, and no questionable assumptions are introduced."-Commonwealth, May, 1926. " This is a text-book on Christian Evidence we would readily place in the hands of the lay-worker as an essential part of his equipment."-Lay Reader, Dec., I912. " We have often privately recommended this work to seekers after truth who have written to us in perplexity."-Church Monlthly, Jan., 1932. " It has done work of an inestimable value in defence of the Christian Faith in the face of every kind of criticism and antagon- ism."-Church Union Gazette, Nov., 1931. " It is one of the best books of its class, readable, candid, convincing and thorough. It would be cheering news to hear that it had been widely read."-Church Intelligencer, Oct., g905. " This is the kind of book which strengthens believers and makes converts. It is one which should be placed within the reach of every lad at that period of his life when he begins to think for himself."-The (Church Lads) Brigade, Oct., 1905. "We have never met with any book which can be more confidently recommended."-Church Army Review, Dec., 1925. " It offers an admirable, thorough and terse examination of the more important arguments for and against believing in our Holy Religion. It should be in the hands of every teacher and preacher." -Irish Churchmlan, 22nd Aug., 1931. "This book is an old friend of mine.... I have constantly found it most serviceable. ... I know of no better book of its kind; it is reasonable, candid, and convincing, and admirably lacking in controversial bitterness."-Fiery Cross, Dec., I93I. " There is no book of this class known to The Canadian Teacher so complete and conclusive.
