Of course, coke quality varies with the quality of the bituminous coal from which it is made, just as the quality of anthracite varies. The quality of anthracite seems to be gradually decreasing whereas the quality of coke grows better as more is learned about its manufacture. With this in mind it is not difficult to imagine coke entirely taking the place of anthracite, at least at points remote from the mines. Conclusion In 1881, Sir William Siemens said: "I am bold enough to go so far as to say that raw coal should not be used for any purpose whatsoever, and that the first step toward the judicious and economical production of heat is the gas retort or gas producer, in which the coal is converted into gas, or gas and coke, as is the case at our ordinary gas works." A study of the curve of coke production and the map, Fig. 1, showing the location of byproduct coke-oven plants in the United States will show that the development has been rapid. For the duration of the war, it is probable that it will be impossible to meet the demand for by-products. It is to be hoped that the war will be over before some of the plants now under construction are completed. In any event, when peace does come, we will be confronted with the problem of utilizing most advantageously the byproducts that will result from a normal production of coke. By summarizing the fuel values recovered in by-product ovens, we can satisfy ourselves that at least 25 per cent of the fuel value of the coal coked in bee-hive ovens is wasted. If we are to promptly secure the great saving in national resources that inevitably results from the widespread use of by-product ovens, it will be the mission of more
