3o8 AUTOBIOGRAPHY OF JOHN FRITZ
tionized the chenflcal flidustries to a large extent, and are bound to revolutionize metaUurgy much more than has yet been done. We can almost see our way clear to the giving a candle power of light for say a quarter of a watt, or 1500 candle power to a horse power perhaps — not the 2000 candle-power arc Ught that you have aU heard of, that only measures three or four or five hundred actuaUy, but 1500 real cancUe power. We have given you not only one kind of Ught, but half a dozen different kinds of light, and those half-dozen different kinds of Ught having their own special field.
We have in these few years revolutionized the street-rail¬ way systems and we are boimd to revolutionize fli time those great systems that extend over the country for hundreds and hundreds of mfles. From the electric furnace we have produced the best abrasives, the hardest substances, and we have even produced the diamond. At the same time we have some furnaces that have produced not the grittiest and hardest of substances, but almost the softest of soUds, which wfll flow under pressure Uke Uquid,— an artificial graphite. We have given you aluminum, the Ughtest of metals, with aUoys which make it almost as common as brass and cheaper bulk for bulk. There is even a promise that we may be able to attack on a commercial scale the elements of the atmosphere, nitrogen and oxygen, and unite them commerciaUy and produce nitrates for use in the fertilization of lands.

Now we are, as it were, on the threshold of this develop¬ ment. Within a few years we have had a most surprising development in the way of transmission of signals for long distances. The telephone itself was wonderful enough,— a Uttle piece of sheet metal in front of a magnet with a coil on it through which you could talk over enormous distances — but we have, as it were, seized upon the whole ether sur-
