land. An improvement "on " the land, or " appertaining thereto,"
is a concrete thing, having a recognizable existence and identity
distinct from the land on which it is "made," with a locality and
extension of its own. An improvement "of" the land has an
abstract denotation indicating a better quality or condition of the
land itself, but having no independent existence or identity.
Tnstances of the former are readily suggested, as a house, a fence,
a bank, a wall, a tank, a right of light or water from an adjoining
tenement; and so on. The latter is not a thing, but the qualitative
result of some act. The removal of scrub, of noxious weeds or
vermin, the clearing of stones, the cutting down of a hill, the filling
up of a hollow, the drainage of a swamp, the grubbing of stumps,
are all acts which leave only beneficial results in the form of an
improved condition of the land itself, that is, of the bare land or
"site" as it exists at the moment of valuation, but add nothing to
it, though they add to its valwe. Lord Dunedin's words seem to me
as to this hardly susceptible of doubt; the "plot of land" as
contrasted with "nothing on it in the way of improvement." To
remove a detriment is, of course, an improvement to the land or of
the land, but does not constitute an improvement on, or " appertain-
ing to" the land. The force of this may be more fully appreciated
when one remembers that after the removal, say, of valuable building
timber naturally growing, it would not be correct to say there was
a detriment on the land. The land was thereby probably rendered
less valuable, but the absence of a given object does not constitute
_ the presence of its opposite. To call the mere past removal of an
obstruction or any other positive detriment - such as prickly pear -
an existing improvement on the land as it exists at the date of valua-
tion, is not, I think, consistent with the general understanding of
the quoted passage in Toohey's Case (1). The prevention of a
detriment is still further removed : it leaves the land precisely as it is.
'The third point is clear, and in effect it cuts away one source of
confusion as to improvements. I need say no more about it except
this: that it would, in my opinion, be a violation of it to substitute
"value of improvement " for "improvement on the land." What
Imean is this. It would be a violation of the third point to ask
