of Indiana and portions of each sample sent to each member of the Committee for analysis. We hope to have some results to report by the time of this year’s meeting of the A. 0. A. C., but it will undoubtedly take a longer time before final recommendations can be made. I t is very encouraging to note that the interest aroused by the subject of sampling has been quite general. \Ye learn that a large number of orders have been placed with the maker of the Indiana sampler, and that several additional states have adopted its use. We are also in receipt of a communication from the Chief Chemist of the Department of Agriculture and Stock, Queensland, Australia, outlining the sampling methods which were drawn up a t that place by a Committee, and to learn that not only was the Indiana sampler adopted, but an entire set of regulations had been drawn up which can be subjected to very little criticism. We feel that both the industry and state control will be greatly benefited by the agitation of this sampling question. F. S. LODGE,Chairman C. H. JOKES a‘.J. JOKES.JR.

At the last meeting of this division a motion was made and passed appointing a committee to formulate methods for the REPORT OF THE COMMITTEE ON RESEARCH AND sampling of fertilizers, to be presented to the Association of METHODS OF ANALYSIS Official Agricultural Chemists, requesting that the Bssociation adopt a standard method for sampling fertilizers, which would FERTILIZER DIVISION, AMERICAN CHEMICAL SOCIETY be official. Boston, September 12, 1917 The members of your Committee did not deem it feasible The work on the determination of sulfur in pyrites has been to work out such methods before the annual meeting of the Association in November, 1916. However, the Chairman ap- carried forward by Mr. H. C. Moore, Armour Fertilizer \Vorks, Atlanta, Georgia. Your Committee is advised by Mr. Moore peared before the members of the Executive Committee of the Association of Official Agricultural Chemists during their that he is not yet ready to render a final report, owing to his failure t o receive results from all collaborators and the hope annual meeting, stated the action of the Fertilizer Division of of receiving the missing Kesults later. the American Chemical Society, and requested the cooperation The results so far received have been tabulated as follows of the Association. by Mr. Moore! As a result of this conference the Chairman of the ilssociation was instructed to appoint a Committee of three to cooperate “SUMMARY OF RESULTS REPORTED BY 45 ANALYSTS FROM 32 with the American Chemical Society Committee to draw up LABORATORIES ON PYRITES SAMPLE NO. 4 satisfactory methods for the sampling of fertilizers, which might MISCELLANEOUS MISCELALLEN & BISHOP MODIFICATIONS OF be adopted as official.
