matter of fact.'" Now, it is all important to adhere to the care-
fully-worded formulation of the rule. 'The formula says not a
word about putting the premises into repair or keeping them safe.
It is the person, the visitor, who is to be kept safe, so far as
reasonable care can do it. The duty of the invitor is to "use
reasonable care to prevent damage from unusual danger which he
knows or ought to know "; that is what the invitee is "entitled to
expect." The invitor, however, may choose his own way of doing
it; he may, if he pleases, endeavour to prevent damage by making
the place as safe for the invitee as such a place with its incidental
risks usually is - the invitee himself being bound then to look
after his own safety by exercising reasonable care on his part.
But the occupier is not bound, apart from legal enactment or
contract, to tie himself down to this mode of guarding the safety
of'the invitee. He is not bound to alter his premises, which are
his private property and under his sole dominion; his duty,
though arising in relation to his premises, is not in respect of his
premises as the subject matter of his duty. The subject matter
of his duty is his visitor. And so the occupier may leave his
premises dangerous, provided he reasonably protects the invitee.
If, however, the occupier omits to make the place reasonably
safe, having regard to its character, so that there is in fact
unusual danger which he knows, or ought to know, then his
reasonable care of his visitor must take another form. Willes
J. says (1): - * Where there is evidence of neglect, the question
whether. . . reasonable care has Leen taken, by notice, lighting,
guarding, or otherwise, . . . must be determined by a jury
as a matter of fact." The learned Judge does not say where
there is "neglect," but where there is "evidence of neglect," which
covers the whole field, then the question of whether reasonable
care has been taken to prevent damage by any means whatever
- in other words, whether there has in fact been "neglect " - is
to be decided by the jury. In the Exchequer Chamber, in a
passage, one phrase of which not affecting the present point
requires later consideration, Kelly C.B. says (2): - * If a person
