 Engineers. In folio, strongly half-bound, 30/. 



^*^ Published zoUh Concurrejice of the Surveyors-General for Neiv South 

 IVa/es and Victoria. 



"Mr. GuRDEN is to be thanked for the extraordinary labour which he has bestowed 

 on facilitating the work of the Surveyor. . . . An almost une.xampled instance of 

 professional and literary industry." — Atlienamm. 



" 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. 



"We cannot sufficiently admire the heroic patience of the author, who, in order to 

 prevent error, calculated each result by two different modes, and, before the work was 

 finally placed in the Printers' hands, repeated the operation for a third time, on revising 

 the proofs." — Engineering. 



'_' Up to the present time, no Tables for the use of Surveyors have been prepared, 

 which, in minuteness of detail, can be compared with those compiled by Mr Gurden. 

 . . . With the aid of this book, the toil 0/ calculation is reduced to a minimutn ; 

 and not only is time saved, but the risk of error is avoided. Mr. Gurden's book has but 

 to be known, and no Engineer's or Architect's office will be without a copy." — Architect. 



"A valuable acquisition to those employed in extensive surveys." — Building Ne7vs. 



" These Tables are Characterised by absolute simplicity ; the saving of time 

 effected by their use is most material. . . . Every one connected with Engineering 

 or Survey should be made aware of the existence of this elaborate and useful set of 

 Tables." — Builder.
