ith oil there is not the same cleanliness as with gas; while
there is also more trouble, attention, and considerable danger attending
its use. Still, in these "hard times," most people are inclined to adopt
the cheapest article, even at the cost of these drawbacks, so as to make
their money go as far as possible.

But not only as an illuminant is it being brought into direct
competition with gas, but also as a fuel and for cooking purposes, as
well as for motive power. And I am inclined to think that the sooner we
set about trying to solve the problem of how to meet this new
competitor, the better.

OIL IN GAS MAKING.

A new departure has also recently taken place in the adoption of oil for
gas making purposes. This, of course, is more fraught with danger to the
coal master than to gas companies, inasmuch as, should this prove to be
a more economical raw material from which to produce illuminating gas
than coal, our present coal gas works could be easily remodeled and
turned into oil gas works. This process has recently been introduced
into a village in Fifeshire. And I have made it a point to visit and
inspect the works, which have been converted into an oil gas works, so
that I might be able to lay a few particulars before you. The process,
however, has not been in operation long enough to enable me to give you
much information on the subject, especially in the way of details of
cost, working expenses, or permanency of the gas under varying and low
temperatures. The patentees claim that they can produce 100 cubic feet
of 60 candle gas from a gallon of oil, or at a cost of 3s. 11d. per
1,000 cubic feet for oil, fuel, and labor; no more expense being
incurred, as the gas does not require purification.

At Colinsburgh (the village alluded to), I was informed that the man
sent by the patentees could produce 100 cubic feet of gas per gallon of
oil; but they had no means of testing the illuminating power. The gas
company's own servant, however, only produced 80 cubic feet per gallon,
which they attributed to his want of experience in knowing the proper
heat at which to work the retorts. Whether or not this was so I cannot
tell; but of this I am certain, that the statement made that the gas
does not require purification will not bear investigation. When I tested
it for sulphureted hydrogen and for ammonia, both were indicated in such
an unmistakable manner as none of us would care to see in our coal gas
as sent out to
