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

"Tri-nitro-glycerine, as Applied in the Hoosac Tunnel, Submarine Blasting, etc." by Geo. M. Mowbray is a scientific publication written in the late 19th century. The text discusses the properties and applications of the explosive tri-nitro-glycerin, particularly in relation to its use in the construction of the Hoosac Tunnel and various submarine blasting operations. Topics include manufacturing details, safety considerations, and the comparison of tri-nitro-glycerin with other explosives. At the start of the work, Mowbray recounts historical explosions caused by nitro-glycerin, highlighting notable incidents in New York and San Francisco that led to significant destruction and loss of life. The text emphasizes the importance of understanding this explosive's properties to ensure safety and efficacy in engineering applications. Mowbray's motivation to explore the use of nitro-glycerin stems from the need for a powerful and reliable blasting agent that could improve tunneling efforts, as evidenced by experiments and reports from engineers involved in the Hoosac Tunnel project.
