By RICHARD LLOYD GURDEN, Authorised Surveyor for the Governments of New South Wales and Victoria. \* Published with the Concurrence oj the Surueyors-General for New South Wales and Victoria. “Those who have experience in exact Survey-work will best know how to appreciate the enormous amount of labour represented by this valuable book. The computations enable the user to ascertain the sines and cosines for a distance of twelve miles to within half an inch, and this by reference to but One Table, in place ot the usual Fifteen minute computations requireü. This alone is evidence of the assistance which the Tables ensure to every user, and as every Surveyor in active practice has felt the want of such assistance few knowing of their publication will remain without them.” —Engineer. Strongly Bound in Super Royal 8vo. Cloth Boards. 7s. 6d. net. BONUS TABLES: For Caleulating Wages on the Bonus or Premium Systems. For Engineering, Technical and Allied Trades. By HENRY A. GOLDING, A.M.Inst.M.E., Technical Assistant to Messrs. Bryan Donkin and Clench, Ltd., and Assistant Lecturer in Mechanical Engineering at the Northampton Institute, London, E.C. . “C^vjot fail to prove practically serviceable to those for whom they have been designed.”—Scotsman.
