"This book has kept your reviewer awake when he reasonably expected to be otherwise engaged. We do not remember coming across a more fascinating volume, even to a somewhat blasé reader whose business it is to read all that comes in his way. The marvels miracles they should be called, of the modern workshop are here exploited by Mr. Williams for the benefit of readers who have not the opportunity of seeing these wonders or the necessary mathematical knowledge to understand a scientific treatise on their working. Only the simplest language is used and every effort is made, by illustration or by analogy, to make sufficiently clear to the non-scientific reader how the particular bit of machinery works and what its work really is. Delicate instruments, calculating machines, workshop machinery, portable tools, the pedrail, motors ashore and afloat, fire engines, automatic machines, sculpturing machines--these are a few of the chapters which crowd this splendid volume."--_Educational News._ "It is difficult to make descriptions of machinery and mechanism interesting, but Mr. Williams has the enviable knack of doing so, and it is hardly possible to open this book at any page without turning up something which you feel you must read; and then you cannot stop till you come to the end of the chapter."--_Electricity._ "This book is full of interest and instruction, and is a welcome addition to Messrs. Seeley and Company's Romance Series."--_Leeds Mercury._ "A book of absorbing interest for the boy with a mechanical turn, and indeed for the general reader."--_Educational Times._ "An instructive and well-written volume."--_Hobbies._ SEELEY & CO., LTD., 88 GREAT RUSSELL STREET.
