of success, which are (i) the species of timber with which to experi¬ 
ment, (ii) the cost of treatment, and (iii) the antiseptics with which to 
work. It will be necessary to deal with each head separately. 
{ a ) Species of Timber. 
Species of Timber with which it is proposed to experiment . 
On page 11, section 3, Chapter I, is given a list of timbers, divided 
into three classes, according to their value as possible sleeper-woods, while 
the remaining portion of that section is devoted to their relative merits. 
It is proposed that future experiments, with possibly slight modifica¬ 
tions, shall be confined to these timbers, and that those in class I shall 
be dealt with before those in class II, etc. 
(6) Cost of treatment. 
Before it is possible to decide on the antiseptics with which experi¬ 
ments should be made or by what process the timber should be treated, 
it is necessary to briefly review the figures of cost of treatment. 
As we have many possible methods of treatment to consider, which have 
been fully discussed in the previous chapters, it will simplify matters 
to tabulate the figures deduced from previous experiments and actual 
working so as to form a fair conception of their relative merits. The 
following figures of cost of treating a B. G. sleeper are taken from the 
body of this report:—
