Kentucky Agricultural Experiment Station. ix · types recognized by the United States Bureau of Soils and has in progress pot culture experiments upon two of the A different types from that County. It may be interesting to mention here that one of these is the Devonian black shale soil from Berea, which was foundto be so strongly acid that cloveriwould not grow upon it, but where lime and phosphate were used in the pot experiments, an excellent V o growth was obtained. The pot experiments mentioned in the last report are being continued. We have given more time than usual this year to the U- study of methods of analysis and think we have decided ‘ upon a method of determining small quantities of potas- sium in soil solutions whichiwill give satisfactory results. . ` We have also done a large amount of work upon the deter- mination of carbonate of lime in soils. This is a very important determination in connection with the question of _ soil acidity and we have found it difficult to get concordant results where only a small quantity of carbonate of lime is present, hence an accurate method. ` . Work has been done upon methods of analysis of insect- . icides and of mineral waters, and on account of the fact that Mr. Shedd is Referee upon Inorganic Plant Constitu- ents for the Association of Official Agricultural Chemists, it - was necessary for him to give much time to this subject and more particularly the determination of iron, alumina and phosphoric acid in plant ash. It was also necessary for I Dr. Peter, as a member of the Committee of the American Chemical Society upon the analysis of phosphate rock, to give much time to that subject. On account of the important developments of phos- _ phate in Woodford County, we have been called upon to A _ analyze quite a number of samples of phosphate rock from both Woodford and Fayette Counties.
