Abstract
"One f the real effective weapons in cannon hunting is the detector of underground metal. A member of CHAOS, Olin Spoon, makes such detectors in the Simcoe Laboratories at Goldendale. Incidentally, his detectors are useful for detection of underground metal other than cannon, e.g. water pipes. It was originally designed to locate placer gold. I hope that Yakima cannon hunters may be able to get hold of a small cannon and some black powder to use for saluting purposes at the time the C of C has its cannon meeting. It could be used to either open or close the session. If enough powder were used, it might do both at one belch."
