and the way in which Asphalte is laid, Chemical
changes may be looked for, which may not be
invariably uniform in their symptoms, while in the
materials used in a McAdam Road, all Chemical
changes are past, and we know exactly what the
matenals in the changeless form will do. Making
good disturbances after once laying is also an
important item. The judicious use of rollers is
another subject still requiring a little judgment;
in such a Parish as St. James's, steam rollers do
not appear to meet the difficulties of the case, as
of necessity the horse traffic must be more or less
suspended; whether or not horses as a rule can
ever be accustomed to them I cannot sav, but the
V '
result of our experience here is that for general
purposes, not special occasions, a good roller,
capable of the weight being adjusted, and drawn
by horses is the most useful; and I think for repairs
to McAdam Roads, (not forming New), a roller
varying from three to seven or eight tons will be
found most convenient; fifteen or twenty tons is
certainly too much for this purpose. As the use
of a roller at all is now an admitted necessity, I
trust the Parish of St. James's will soon begin to
entertain the idea of providing themselves with one
of their own.
With these few observations, the subject of the
Paving Works may be passed over, nothing special
requires any special observations, and the whole of
the matters have been so well and completely
discussed in the Works Committee from time to
time, that such interest as is connected with the
matters in question has been felt by those whose
duty it is to advise the Vestry as to the Works that
should be executed. The next report will I trust,
