no artificial preparation of the k i n d could be expected to possess.
I t w i l l i n all probability be found that a very slight treatment
w i l l render it suitable for employment i n the construction of
roads, footpaths, courtyards, etc., for asphalting the flooring of
granaries, basements of warehouses, and the like, and further
as a roofing material. Should it be deemed more expedient
to separate the bitumen, this may be effected by simply boiling
or macerating the material with hot water, when the bituminous
matter, entering into fusion, w i l l rise as a scum to the surface
and may be removed by skimmers, whilst the sand falls to the
bottom of the vessel.
A n experiment was made i n order to ascertain the greatest
state of purity to which the bitumen could be brought by this
method; it was found that of the 81.73 per cent, sand, 69.26
per cent, had been removed, the extracted bitumen containing
50.1 per cent, sand, and— owing to the extreme fineness of a
portion of this latter, as already mentioned— it may be questioned
i f the purification by this method could be pushed much
beyond this.
The sand separated by this process, when carefully conducted,
is free or almost free from bitumen, and might, after
being heated to redness i n a reverberatory furnace— to destroy
any little adhering bitumen— be advantageously employed for
the manufacture of one of the better qualities of glass.
The above treatment requires hut the simplest of appliances,
and might be readily carried out on the spot.
The amount of maltha at my disposal was far too small to
warrant any attempt at its distillation. Should it occur in
sufficient quantity it might possibly, amongst other uses, be
k advantageously employed as a crude material for the manufacture
of illuminating and lubricating oils and paraffin.

The belt of timber, which at Fort Anderson ( established on
Anderson River in 1861, and abandoned 1866; approximate
latitude, 68° 30' north) extends for over thirty miles to the
eastward, rapidly narrows and becomes a mere fringe along the
Anderson River and disappears to the northward of the sixty-ninth
parallel of latitude. The country is thickly interspersed
