how would you recover the potash at a profit12 If you are interested, read the solution in their article. The problems of a brine working plant, like that of the American Trona Corporation, were described last year. Progress since that report has been good. Equilibrium study of the system sulfates, chlorides, and carbonates of sodium and potassium between 20’ and 100” has been completed for our purpose. Other equilibrium studies have included borax, metaborate, carbonate, bicarbonate, and other combinations. Of some scientific interest is the discovery by Mr. W. E. Burke of still another double salt, NazBz04.2NaC1,4H20, to which he has temporarily given the euphonious name of “teepleite.” Some practical applications of these studies have been: (1) An improvement in the grade of potash produced (for the last two months the product made has not in any week dropped below 95 per cent of KCl and several weeks has reached 98 per cent); (2) increase in the percentage of potash recovered; (3) simplified method of making borax; and (4)cheap and simple method of making boric acid. Work on the other difficulties has been equally successful. Foaming in the evlporators has been entirely under control for a long time, The presence of borax as an impurity in potash has not been a problem for nearly three years, in spite of the fact that our friends, the recent enemy, are still talking about it. Dr. Whitney, Chief of the Bureau of Soils, recently issued another official statement on the high purity of American potash to counteract their propaganda, and agricultural experiment stations all over the country have been doing the same thing. It is amazing how many restatements of truth it takes to kill one lie. Other improvements in evaporating, cooling, handling, and control have all reduced production costs. Much research work is under way, directed toward recovery of other valuable products from Searles Lake, and this is progressing favorably. COSTAND MARKET Potash is one of the very few materials that is cheaper now than it was before the war-64 cents per unit to-day compared with an average of about 80 cents formerly. Converted to marks, this is about 330 marks to-day compared with 3.3 marks in normal times. The German workman used to receive 3.50 to 5 marks ($0.84 to $1.20) for a day’s work. Now he receives 150 to 300 marks, say, 30 to 60 cents. In marks his wages have been multiplied by 50, while the price of potash has been multiplied by 100. I n dollars he receives less than half what he did before, and works a whole day for what the American workman receives per hour. It takes on the average 12 to 15 days’ work in Germany to produce 100 units or one ton of actual KzO. This sells here a t $64 and the labor cost for the 12 to 15 days’ work is about $6 or $7. In America we would pay for that same amount of labor about $40. As a matter of fact, the labor spent to produce a ton of KzO in America is less than four days in a good plant. We can turn out four times as much potash per man-day as they do, but we pay the man eight times the price the German receives. This is bound to continue so long as the value of the mark is falling faster than the price of German labor in marks is rising. There will always be a discrepancy because the American workman demands and we want him to have a higher standard of living than any other workman. This is why the industry needs temporary protection now. It will continue to need it until the production costs can be cut still lower. If we had a standard by which we could measure cost in terms of man-days, power, and steam on an even basis, America could probably sell at a profit to-day a t any price 6

that Germany could. But with the American man-day costing 8 to 10 times what the German one does we are calling for temporary help.

PROPAGANDA In a review of this kind it should not be necessary to discuss propaganda and possibly it ought not to be done, but it is necessary and is going to be done. Last fall we were deluged with a series of interviews from bankers, college professors, and business men. All agreed that there was no American potash industry, never had been, and never would be, and anyway American potash was bad and dangerous and God had given Germany good potash and plenty of it. It was almost sacrilegious to consider any potash but the German. For such a wide diversity of men, none of them directly connected with potash, there was an astonishing unanimity in ideas, and even in words and figures used. One could almost believe the interviews were mimeographed in one office. Then some interviews from fertilizer men complaining of the impurities in American potash, and specifying borax and salt. At that very time the nitrate of soda they were using often contained more borax than any American potash, and the German potash they used frequently contained more salt than it did potash. Again, about June first, we find advertisements in papers like the Rural New Yorker and the Louisiana Planter still harping on borax in potash, apparently in the hope of influencing some poor ignoramus who had not seen the repeated official government denials that harm could come from American potash more than from any other. These advertisements were signed “United States Soil and Crop Service, Potash Syndicate.” This name looks harmless and patriotic but it is the official name of the Propaganda Office for North America of the German Kalisyndikat. I would not bother you with this recitation except that it is a part of the struggle for existence that American potash has been making for the last two years, and an appreciable amount of time of technical men in the industry has been consumed in combating just that kind of stuff. Many of us hoped that with the departure of the Kaiser from German affairs God and His Providence would no longer be restricted to Germany, but might be allowed to operate elsewhere. But not so! Within a month, two German business men assured me that Germany had a world monopoly on potash which could never be taken away. God had given it to her and she could starve or feed any part of the world she chose. This is of course hard on America. Who put the potash in the Nebraska and California lakes, the Utah marshes, the cement rock and the molasses, the greensand, alunite, and leucite? Are they not as natural as anything the other side of the Rhine? And are they not more accessible, being on the surface instead of far underground? German propaganda is meant for the unthinking and the unthinking often swallow it, particularly if it is signed with what looks like an American name.

THEFUTURE The foregoing is a picture of the American potash industry during the last two years as I see it. To be a large industry that will protect Americans against future high-priced potash it needs some support and encouragement now. Some part of it will live whether it gets that support or not, but may be not enough to be a real protection. These plants cannot start operation again suddenly if they are allowed to die now. It takes time and money, and money does not lightly reenter an industry that has been allowed to fail from lack of public support at a critical time. We will have a large industry if we support it now, and a small one whether it is supported or not.
