Flame Safety Lamps
Description:
From Introduction: "However, before the flame lamp becomes obsolete, it is fitting that the Bureau of Mines compile a permanent record of a device which has served the mining industry for more than three generations, and not only made possible the development of entire districts that otherwise could have not been worked but undoubtedly saved the lives of thousands of underground workers."
