Practical Tunnelling, 



PRACTICAL TUNNELLING : Explaining in detail the Setting 

 out of the Works, Shaft-sinking and Heading-Driving, Ranging 

 the Lines and Levelling under Ground, Sub-Excavating, Timbering, 

 and the Construction of the Brickwork of Tunnels with the amount 

 of labour required for, and the Cost of, the various portions of the 

 work. By Frederick Walter Simms, M. Inst. C.E., author 

 of "A Treatise on Levelling." Third Edition, Revised and Ex- 

 tended, with additional chapters illustrating the Recent Practice ot 

 Tunnelling as exemplified by the St. Gothard, Mont Cenis, and 

 other modern works, by D. Kinnear Clark, M. Inst. C.E. 

 Imp. 8vo, with 21 Folding Plates and numerous Wood En- 

 gravings, 30 J., cloth. 



It is the only practical treatise on the great art of tunnelHng. Mr. Clark's work 

 brings the exigencies of tunnel enterprise up to our own time. The great length of 

 modern tunnels has led to a new difficulty in the art, which the last generation was 

 ignorant of, namely, the difficulty of ventilation. In Mr. Clark's supplement we find 

 this branch of the subject has been fully considered. Mr. Clark's additional chapters 

 on the Mont Cenis and St, Gothard Tunnels contain minute and valuable experiences 

 and data relating to the method of excavation by compressed air, the heading 

 operations, rock-boring machiner^'-, process of enlargement, ventilation in course of 

 construction by compressed air, labour and cost, &c." — Building Nezvs. 



*' The estimation in which Mr. Simms' book on tunnelling has been held for over 

 thirty years cannot be more truly expressed than in the words of the late Professor 

 Rankine : — * The best source of information on the subject of tunnels is Mr. F. W. 

 Simms* work on " Practical Tunnelling.'' ' — The Architect. 



Levelling. 



A TREATISE on the PRINCIPLES and PRACTICE of 

 LEVELLING ; showing its Application to Purposes of Railway 

 and Civil Engineering, in the Construction of Roads ; with Mr. 

 Telford's Rules for the same. By Frederick W. Simms, 

 F.G.S., M. Inst. C.E. Sixth Edition, very carefully revised, with 

 the addition of Mr. Law's Practical Examples for Setting out 

 Railway Curves, and Mr. Trautwine's Field Practice of Laying 

 out Circular Curves. With 7 Plates and numerous Woodcuts. 8vo, 

 Ss. 6d, cloth. Trautwine on Curves, separate, 5^. 



** One of the most important text-books for the general surveyor, and there is 

 scarcely a question connected with levelling for which a solution would be sought but 

 that would be satisfactorily answered by consulting the volume." — Mining Journal.

The High-Pressure Steam Engine. 



THE HIGH-PRESSURE STEAM ENGINE; an Exposition 

 of its Comparative Merits, and an Essay towards an Improved 

 System of Construction, adapted especially to secure Safety and 

 Economy. By Dr. Ernst Alban, Practical Machine Maker, 

 Plau, Mecklenberg. Translated from the German, with Notes, by 

 Dr. Pole, F.R.S., M. Inst. C.E., &c. &c. With 28 fine Plates, 

 8vo, i6j-. (id. cloth. 

 " A work like this, which goes thoroughly into the examination of the high-pressure 



engine, the boiler, and its appendages, &c., is exceedingly useful, and deserves a place 



s every scientific library." — Steam Shipping Chronicle,
