By RICHARD LLOYD GURDEN,
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.
