to this Court. Sec. 6 (1) of the Workers' Compensation Act 1912-1924
of Western Australia makes the familiar conditions of the employee's
right to workers' compensation alternative, and not cumulative as
in the British statute. It is not necessary that the accident shall
arise both out of and in the course of the employment. It is enough
if it arises either out of or in the course of the employment.
Accordingly, in this case the appellant must succeed if the accident
arose in the course of the employment. In the circumstances in
which it occurred, the accident could not be considered to arise out
of the employment, at any rate unless it also arose in the course of
the employment. It has been said that in Charles R. Davidson v.
M:Robb (1) a decision was given upon the words " in the course of the
employment " which is final and that it only remains to apply it in
other cases. Its application, however, has not proved simple. There
can no longer be any doubt that the accident must happen while
the employee is doing something which is part of or is incidental
to his service. It is another matter to be sure what is included
within this conception. In Pearson vy. Fremantle Harbour Trust (2)
some passages are collected from judgments in the House of Lords
in which illustrations are given of acts done by workmen which are
preparatory or incidental to or consequential upon the performance
of their actual work. As the test is not, and could not be, whether
the employee was obliged to act as he was doing when the accident
occurred, the inclusion of things arising out of the actual performance
of his duty was, no doubt, inevitable, but, as a result, the sufficiency
of the connection between the employment and the thing done by
the employee cannot but remain a matter of degree, in which time,
place and circumstance, as well as practice, must be considered
together with the conditions of the employment. In this case the
question appears to be whether the presence of the appellant at
the place where he was struck by the cricket ball was connected
with the actual performance of his duty in a sufficient degree.
His work was that of an iron machinist. The award which regulated
his employment provided for a week's work of forty-four hours,
extending over five or six days at the choice of the employer, and
