NOTE.
Mr. J. W. Gregory, writing in the Contemporary Review, says the quantity of oil in the world is totally inadequate to serve constantly as a primary fuel. Therefore, he thinks, irreplaceable mineral oil should not be used for the boilers of tramp steamers, or petrol used for purposes that could be met by a refuse-burning Diesel engine. In 1918 the world's output of oil was about 70,000,000 metric tons, which would be equivalent to from 90,000, 000 to 100,000,000 tons of coal, whereas the total out put in 1913 was 1,477,000,000 tons. Any general replacement of coal by oil is therefore, impossible, and it is doubtful whether the present output can be long maintained. Petrol, or gasoline, is indispensible for aircraft and light motors, and the development of aerial navigation will be seriously handicapped if, in a few decades hence, aeroplanes have to use an inferior fuel because the world's stock of petrol has run low.
