ported that arsenic was absent while “C” reported the presence of a conszderable amount of arsenic. “C” was corroborated in his report b y “D” (another analyst). What credence is t o be given the report of “ B ” ? If “B’s” methods are faulty, what is t o warn a manufacturer of this fact? What redress has “A” if the report of “C” and “D” should prove inaccurate and needless anxiety has been caused by this fact? To conclude, if the title 6f chemist, analyst, and so on, is given b y the American Chemical Society t o those of its members who possess definite qualifications, the manufacturers of our Country will cease t o remark t h a t “chemists are bluffers” as one gentleman recently p u t i t in a private conversation. In other words, it is a pleasure t o have one’s name recorded as a member of our Society, but i t should be a n honor t o be recognized as a qualified consulting chemist or analyst b y the American. Chemical Society. FREDERIC DANNERTH.
-THE POTASH SUPPLY. There will always be a “potash situation” and the possibility of a controversy so long as the world’s supply of potash happens t o be lodged in one country a n d is controlled b y a monopolistic combine of which the government of the country in question through its ownership of mines is a part. At the bottom of the recent and present controversy between the American consumers of potash and the German producers stands the fundamental fact t h a t we are forced t o buy our potash of Germany because there is n o other source of supply. Germany can charge all that the trade will stand, for her potash, in defiance of any natural laws of supply and demand and Americans will have t o pay the price. The general situation has changed but little during the year and indeed not much change was expected after the failure of our government t o reach a successful conclusion in its diplomatic negotiations. The American contractors, who arranged for the delivery of their requirements through an American concern which had in turn contracted with the independent mines, are paying syndicate prices for their deliveries, although the money is paid under protest on account of the sur-tax, and i t is possible t h a t some settlement will later be arrived at.
The great hope of American consumers lies in the discovery of adequate potash deposits in the United States. The government has wisely appropriated a sum of money, for the purpose of prospecting and investigating probable sources of supply. Recently announcement has been made b y the Secretary of Agriculture t h a t potash has been discovered in the West in large quantities, b u t details are withheld until the assembling of the next Congress, when they will be communicated t o the legislative committees which haye the matter in charge. I t is t o be hoped t h a t this important announcement will be fully supported b y the facts when they are made known and that the deposits will prove commercially available in the near future. No other influence, it would seem, can change the monopolistic German attitude. The German Syndicate is already greatly interested in Secretary Wilson’s announcement, and i t has been pointed out in the newspapers t h a t even if potash were obtainable in the Western States, it could not compete with German potash on account of high freight rates. Statements have also been made to the effect that before the Syndicate was formed, a n examination was made of possible American potash deposits, and the conclusion was reached t h a t America possessed no deposits large enough t o be worked a t a profit. Feldspar and other potash silicates as sources of soluble potash do not appear to be arousing interest in the fertilizer trade or chemical manufacture. The processes which have been proposed-fusion with common salt or with salt and lime, electrolysis, etc.do not give promise of profitable working. The proposition is a very low-grade one a t best. The best potash silicates carry only 12-14% of actual K,O, and with the addition of fluxes these percentages would be still further reduced. Lixiviation and concentration would probably prove far too expensive, considering the price of the finished product. Soluble potash from insoluble silicates does not appear t o be in the realm of the possible a t the present time. The only hope lies in the discovery of soluble sources of supply, and it is for this reason that the fertilizer and chemical manufacturers as well a s the general public are awaiting with the greatest interest further announcements from the Department of Agriculture.

material to work with and the difficulty of reducing these very electropositive elements from their compounds. What metal has been obtained has been, in most cases a t least, small in amount and very impure, usually contaminated with the other members Of the group. On account Of the rarity Of the materials to work with, little has been done in a study of the physical and chemical propertps Of these rareearth metals, and the field of alloys has been almost untouched.
