eaoh time, you will have 200 pounds. By this method you will reduce the temperature of the fire-box equal to the absorbing quality of the coal, in fact, you will reduoe the temperature so much, that the carbon will pass off unconsumed in the form of smoke, and we need to look out for that, so that communities will not get after us and tell us that we are ruining the health of men and destroying tapestries, lace goods and that sort of thing sorauohthat they are going to put us out of business. The amount of coal placed in, and the frequency with whioh it is put in, has much to do with economy. Some men will put in 15 to 20 sooops of coal at a time, and then sit up on the baok seat and say, "That is fine, see the black smoke rolling out of the stack". Whereas, if we got him down on the deok and insisted on his putting it in at proper intervals of time, and looking for the thin places and plaoing the ooal where it is needed most, it would be easier work for him, Intelligence is what moves the man,

you all know that, because that is what you are developing here, intelligence* 1 might tell you also about the depth of the ooal, upon the grates, how deep it should be; but that must be learned by experience. The ratio of grate area to heating surface is also a very important thing, as well as the ratio of firebox area to tube heating surface. Perhaps you can develop something along that line. I know Dr* Gosa will develop something along that lineftfhe can, and I know if
