First edition. Published on the eve of WWI, this timely manual for the design of a variety of explosive devices and detonators intended for combat engineers, would go through several war-time editions (a second edition in 1914; a third in 1916). The manual presents a full overview of the equipment, tools and instruments of a professional sapper of the early twentieth-century, explaining the chemical composition of various explosive substances, the rules for their proper handling and transportation by water and land. It also provides information on the design of explosive devices and detonators such as hand grenades and land mines. In addition to combat operations, the manual describes a variety of situations that may require blasting operations such as the building of railways, tunnels, bridges, as well as detonation of rock formations and ice. The manual is appended with formulas, tables and graphs that provide additional information on issues related to explosion technology. Numerous technical drawings accompany the text, providing additional visual aid. Not in KVK, OCLC, which show only one copy of the 1914 edition in Melbourne.
