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.

THOUSAND. THE TRUTH OF CHRISTIANITY BY LT.-COL. W. H. TURTON, D.S.O. (late R.E.). EXTRACT FROM PREFACE. I have again carefully revised the whole book, and have made several slight improvements, the most important being in Chapters v., vi., xviii. and especially ix., x., owing to the recent discoveries in Egypt, Ur, and Jericho.

"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, 1920. " 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, I4 th March, 1907. " 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 Til,z s and Mirror, S8th Feb., I907. " It is a book for the hour, and needs to be circulated b X thousands ... straightforward, manly, and convincing."-School master, 27 th March, I909. " 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."-Church Times, 12th Dec., 1919. " If you want a simple book of Christian Apologetics, get Turton's ' The Truth of Christianity.' "-Church Times, 7 th April, 1933. " We have repeatedly expressed our sense of the merit of Col. Turton's book."-Gutardian, 9th Dec., 1908. .. " 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 Churchman, I2th Dec., 1912. " 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, 9th 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."-Chtzrch 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."-Commnonwealth, 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., 1912. " We have often privately recommended this work to seekers after truth who have written to us in perplexity."-Church Monthly, 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., I931. " 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."-Clhurch Intelligencer, Oct., 1905. "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 Churchmanz,22nd Aug., I93I. "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., 1931. " There is no book of this class known to The Canadiant Teacher so complete and conclusive. Every teacher should have a copy." -Canadian Teacher, Toronto, Dec., I920. " Its excellent index' makes it extraordinarily easy to lay one's finger upon any specific point; we tested it, for instance, on this point, the contrast between the Incarnation and Hindu incarnations. In a moment we have been able to find the gist of the whole matter accurately stated in a few words."-Calcutta Diocesan Record, Jan., I913. Roman Catholic. "The gallant Colonel is a non-Catholic, but the subject matter of his book is so admirable that hardly a Catholic periodical in the country has failed to commend it, and that with high and unqualified praise."-The Tablet, Oct., 1925. " We most heartily wish that a copy of it could, be found in the library of every Catholic family, school, and institution."-Catholic Times, Jan., I909. (Sixth notice.) Presbyterian. "One does not know what to admire most in the book-the accurate knowledge gathered from so many fields, the clear reasoning, the sound judgment, or the fine spirit which animates the whole."-Christian Leader, I5th June, 1905. Nonconformist. "He is eminently fair to opponents, clear in statement, and convincing in argument for his own case, and his standpoint is unmistakably evangelical. His style suits his work, being calm, lucid and simple."-Metlhodist Times, 22nd Aug., 1901. " On the whole it is the best popular summary that we have met. It excells in definiteness of purpose, in clearness of statement, in moderation and in conciseness."-Baptist Times, 24th Oct., I902. "To the evangelical reader the book will be a delight; more modernist readers will turn to the book, we believe, time after time, in treating almost any religious subject, to find clear and reasoned statements of views, which, although not theirs, must be taken into account."-Liverpool Congregational Moznthly, Dec., 1925.
