HYDRATED LIME The statistics of the output of hydrated lime include only the product made in hydrating machines and omit hand-slacked lime. There were seven more plants reported as producing hydrated lime in 1923 than in 1922. ^ Hydrated lime increased 11 per cent in quantity and 24 per cent in value in 1923. Hydrated lime sold by producers in the United States, 1921–1923 Hydrated lime sold by producers in the United States, 1922 and 1923, by uses Hydrated lime sold by producers in the United States, 1922 and 1923, by States Alabama.. 56, 024 537, 816 5,984, 240 1, 740, 209 26, 029 385, 955 223, 735 15, 284 280, 444 49, 712 21, 680 98, 188 428, 587 208, 142 1, 196, 344 1, 106, 063 12, 229, 598 In the following table the consumption of lime is estimated by subtracting from the production the quantities reported shipped by producers out of their States and adding the quantities reported shipped in by producers in other States. No account is taken of jobbers' or dealers' interstate business nor of producers', jobbers', dealers', or consumers' stocks, which are quite unknown. Imports and exports are also ignored, but these are insignificant. The estimates are therefore not precise, but they afford the best approximations possible. On this basis almost all the States showed the same or a slightly higher per capita consumption in 1923, and the average for the country was higher." The lime produced in Ohio is more widely shipped than that from any other State; that of Missouri and Pennsylvania has the next widest distribution.

Dorsey, of the United States Geological Survey, from records of the Bureau of Foreign and Domestic Commerce, Department of Commerce. By JEFFERSON MIDDLETON INTRODUCTION Preceding volumes of Mineral Resources and other reports of the Geological Survey and reports of the Bureau of Mines contain information on changes and developments in the feldspar industry and on the composition, occurrence, and uses of feldspar, the geology and mineralogy of feldspar deposits, and the methods of mining and milling feldspar, and the reader desiring such information is referred to those publications. The principal reports are listed below. Bastin, E. S., Economic geology of feldspar deposits of the United States : U. S. Geol. Survey Bull. 420, 1910. Watts, A. S., Mining and treatment of feldspar and kaolin in the southern Appalachian region : Bur. Mines Bull. 53, 1913. Watts, A. S., Feldspars of the New England and northern Appalachian States: Bur. Mines Bull. 92, 1916. These reports are no longer available for free distribution, but the first and third may be purchased from the Superintendent of Documents, Washington, D. C., for 20 and 25 cents, respectively, or the three reports may be consulted in many of the public libraries of the United States. The following late papers on the subject are of interest: Ladoo, R. B., Conditions in the feldspar industry: Bur. Mines Repts. Inv. 2311, January, 1922. Watts, A. S., The marketing of feldspar: Eng. and Min. Jour.-Press, vol. 115, No. 12, pp. 535-538, Mar. 24, 1923. Shaw, J. B., On the control of composition of feldspar: Ceramic Industry, vol. 2, No. 2, p. 91, February, 1924. Staley, H. F., The feldspar problem in enamel making : Ceramist, vol. 4, No. 2, pp. 87-98, May, 1924. PRODUCTION Statistics of production of feldspar are presented separately in tabular form for mine and quarry output as crude feldspar and for mill output as ground feldspar. The crude feldspar is reported in long tons and the ground feldspar in short tons, according to common practice in the industry. The industry made considerable progress in 1923, and the output reached the highest quantity and value recorded. The average value of crude feldspar in 1923 at the shipping points nearest to the quarries was $7.29 a long ton—8 cents higher than that of 1922. The average value of domestic ground . spar was 20 cents a ton lower than in 1922, and that of Canadian spar ground in the United States was 8 cents a ton higher. The |
