“The present (1896) edition has been brought right up to date, and is thus rendered a work to which civil engineers generally should have ready access, and to which engineers who have construction work can hardly afford to be without, but which to the younger members of the profession is invaluable, as from its pages they can learn the state to which the science of tunnelling has attained.”—Railway News.

“The estimation in which Mr. Simms’s book has been held for many years cannot be more truly expressed than in the words of the late Prof. Rankine: ‘The best source of information on the subject of tunnels is Mr. F. W. Simms’s work on Practical Tunnelling.’”—Architect.

“The chapter upon filtration of water is very complete, and the details of construction well illustrated.... The work should be specially valuable to civil engineers engaged in work in Japan, but the interest is by no means confined to that locality.”—Engineer.

“We congratulate the author upon the practical commonsense shown in the preparation of this work.... The plates and diagrams have evidently been prepared with great care, and cannot fail to be of great assistance to the student.”—Builder.
