I'm going to say this isn't OT (off topic) since a lot of cave entrances got found between say 1810 and 1865 in search of good sources for saltpetre, an ingredient of gunpowder.
This from TagNet: 40,000 Pounds Of Saltpeter---How Many Pounds Nirates? By: Doug Plemons (Sevierville, Tennessee) I have been looking for the answer to one question about saltpeter mining. I'm asking anyone else who might know how to figure this out. A particular saltpeter producer in Jefferson County, TN made up 40,000# of gunpowder during the War of 1812 and sent it to Andy Jackson so he would help win the war. My question is, what is the percentage of nitrates that thie shipment had, in pounds? And approximately how much dirt would have to been manhandled to obtain said amount? All the nitrates are reported to come from ONE cave on this gunpowder maker's land. Would it had to have been a fairly sizable operation? I am assuming that there were other customers besides Andy J. --------------------------------------------------------------------- Visit our website: http://texascavers.com To unsubscribe, e-mail: texascavers-unsubscr...@texascavers.com For additional commands, e-mail: texascavers-h...@texascavers.com
