All these experiments have confirmed our belief in the considerable military advantages which will accrue from its use, but until recently it has been impracticable to use it extensively on account of the uncertainty as to the adequacy of its supply and the sufficiency of its distribution among the seaports of the world. We are now assured, however, as regards the supply, that there is sufficient oil on the public lands of the state of California alone to supply all probable naval demands...

It is especially noteworthy that every town gas-works with a modern installation, and every coke-works, can be completed with an electric power generating plant by using its tars. This will have an excellent effect on many municipal and national works. It would take too much time to enter into the details of this question, but one...

There are no cinders and the amount of smoke can be controlled. A considerable reduction in personnel is possible. The weight and space required for boilers are reduced, first, by the reduction in heating surface required, and, second, by the shortening of firerooms. Consequent on the reduction in heating surface is a decrease in weight and cost of boilers....
