“Mr. Copperthwaite’s task has been to compile and condense ... scattered information into one place. He has done his work excellently.... Mr. Copperthwaite divides his book into eleven chapters. Of these the last chapter on ‘Cost of the shield,’ and the first three chapters on ‘Early history, 1818–1880,’ ‘Use of compressed air in engineering works’ and ‘Cast-iron lining for tunnels,’ respectively, are general in character; the remaining seven chapters are collections of descriptions of specific shield tunnel works classified under three heads; Shields in London clay, Shields in water bearing strata and Shields in masonry tunnels.”—Engin.

“The book is undoubtedly destined to be the standard English work on this peculiarly difficult branch of engineering practice.”

Corelli, Marie (Minnie Mackay). [Treasure of heaven: a romance of riches.] †$1.50. Dodd.
The treasure of Heaven which becomes the quest in Miss Corelli’s story is love, and she would demonstrate the fact that riches menace its possession. David Helmsley, an aged multi-millionaire, becomes a tramp in pursuit of definite happiness, he gives and takes in his wanderings and learns both are spontaneous. Finally he is nursed back from death by one who teaches him the great love lesson which, without any matrimonial thought, blesses his closing days.
