Hello,
Does anyone know the origin of the term "bootleg", used here in Canada to denote a short section of a drill hole left by possible unexploded powder. It is illegal to drill new holes within six inches.
There was a piece in an 1899 newspaper with regard to the Silver Islet mine in Lake Superior in which it was said that mining was so close to the lakebed above the workings that miners carried wooden plugs in their "boot legs" to plug any unexpected breakthroughs to the lake above. This would have been before the article as the mine operated about 1870-1884.

I would post this on the Mining History list. If you are not a member I can do it on your behalf.

This might help at least to put 'bootleg' into context. According to the, ever reliable, U S Bureau of Mines "A Dictionary of Mining, Mineral and Related Terms" (a mighty and very useful tome, that came to me after a very good friend saved it from a skip at Yorkshire Chemicals old plant in Leeds):

Bootleg. a. A hole, shaped somewhat like the leg of a boot, caused by a blast that has failed to shatter rock properly [Hess] b. That portion or remainder of shothole found in a face after a blast has been fired. Also called socket
[Nelson]
