Part 2 — BONUS TABLES:

Reading edition

For Calculating 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.

"The adoption of this system for the payment of workmen has created a demand for some handy table or series of tables, by means of which the wages may be easily found without the necessity of any calculations whatever. With the object of supplying this need, the author has compiled the following tables, which have been in practical use for some time past at a large engineering works in London, and have been found of inestimable value. Not only are they of great value as a 'time saving appliance,' the computation of the bonus or premiums earned by a number of men taking only one-tenth the time by the aid of these tables compared with ordinary calculations, but they possess the additional advantage of being less liable to error, as there is practically no possibility of a mistake occurring."—Extract from Preface.

Authorised Surveyor for the Governments of New South Wales and Victoria.

*** Published with the Concurrence of the Surveyors-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 of the usual Fifteen minute computations required. 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.
