The editor of "The Petroleum Review" is responsible for the following interesting statistics concerning the world's production of petroleum :— or about 50,000,000 tons, which, if used for fuel purposes only, would have an efficiency equivalent to about 85,000,000 tons of coal. The world's production of coal, however, is many times larger, and the complete returns for 1911 are as follow :—
These figures demonstrate that there is no reason to apprehend that the supply of petroleum will be in excess of requirements.
