Tri-nitro-glycerine, as Applied in the Hoosac Tunnel, Submarine Blasting, etc., etc., etc.

This work surveys the adoption and field use of nitroglycerin as a high‑power blasting agent, opening with accounts of early accidents and engineers' reports. It presents submarine and terrestrial blasting case studies and examines the explosive's chemical properties alongside detailed manufacturing, storage, and purification procedures. It describes electrical firing methods, construction of detonators and exploders, common explosive mixtures, and summarizes patent disputes. Practical guidance for tunnel drilling and blasting operations, safety directions, contractor memoranda, accident summaries, and technical illustrations round out a practical manual intended for engineers, miners, and contractors.
