but they have not negatived its being a mine." It was held by the
whole Court in that case that whether any excavation in the earth -
be a mine or not depends upon the mode in which itis worked, and not
on the substance obtained from it. Lexicographers, as Dr. Johnson,
Latham, and Jacob, include " quarries " in " mines." See Farie's
Case (2) and Midland Railway Co. v. Robinson (3). At the place last
cited Lord Herschell adds his approval. In the present case the only
importance as to the substance obtained is that it is not coal, and
therefore the place is not within statutory exception. " Mining
operations " in sec, 17 is an expression which, being unqualified by
anything apart from the coal-mining exception, must be given its
usual meaning as understood in Australia. The expression " mining
property " means nothing more than the property on which mining is
carried on. The word " mining " is the same in both expressions, and
is the governing term. '* Mining operations " is, in the first place, a
well-known legislative phrase; as may be seen by referring, for
instance, to the New South Wales Mining Act (No. 49 of 1906), sees.
42, 47, 57, 60, 61, 68 ; the Victorian Mines Act 1915, secs. 3 (definition
of " mine"), 4, 63 and 75, the South Australian Mining Act 1893, sec.
107. The last-mentioned section is a remarkably illuminating pro-
vision. It refers (inter alia) to work necessary to trace any lode, vein or
gutter from any " property" held under " claim" or " mining lease,"
and adds: " Provided that such work shall not interfere with the
'mining operations ' of" the " owner or lessee."" So that " mining
operations" there include mining on a "claim" which has been
pegged out, as well as on a lease granted. The.expression " mining ~
operations " is apt to include all that is done in the way of mining as
that is universally understood in Australia, The phrase " mining
operations" embraces all operations whether by hand or by
machinery and whether confined to excavating the surface, as in
alluvial claims or extended to excavations, hundreds or even thousands
of feet below the surface, by which any valuable deposit, other than the
