BUREAU OF STANDARDS Combustion Method for the Direct Determination of Rubber. L. G. WESSON. Technologic Paper 35. 11 pp. This article was published practically in full in THISJOURNAL, 6 (1914), 459-62. Iodine Number of Linseed and Petroleum Oils. W. H . SMITHand J. B. TUTTLE.Technologic Paper 37. 17 pp. An experimental investigation of the Hanus method for determination of iodine number of oils shows that this procedure should be more exactly defined in order to give reproducible results, particularly with burnt oils. The effect of weight of sample, temperature, time of absorption and amount of Hanus solution were investigated. Observations on Furnishing Temperature and Properties of Rails. G. K. BURGESS,J. J . CROWE,H. S. RAWDON and R . G. WALTENBERG. Technologic Paper 38. 63 pp. This is the first report of a series which will be prepared in connection with the metallurgical and metallographic investigations by the Bureau of Standards in connection with rail specifications. The importance of rolling rails a t proper temperature is well known, but the specifications limiting the shrinkage to 6.75 in. in 33 ft. have been found to be of no importance commercially since this clause does not serve its avowed purpose of limiting the finishing temperature t o a value slightly above the critical range. I n this paper data are given which have been collected from investigations in four representative mills and some experimental work in the Bureau laboratories. I t is concluded that a comparison of chemical analyses, microphotographic examination and physical properties of finished rails, the rolling of which was observed, does not afford sufficient evidence of co-relation t o warrant associating any of the properties either with the temperature of rolling or with each other. Data are given for the thermal expansion of various steels and the commercial significance of the shrinkage specifications is pointed out. GEOLOGICAL SURVEY The following data, taken from advanced chapters of mineral resources for 1913, are of particular interest a t this time as showing relative American production of metals and mineral products and indicating the possible influence of the interruptions of foreign commerce a t this time. Recovery of Secondary Metals. J. B. DUNLOP. Separate No. 5 from Vol. I . 8 pp. Secondary metals are defined as “those recovered from scrap metal, sweepings, skimmings, drosses, etc., and are so called to distinguish them from the metals derived from ore, which are termed ‘primary metals.’ This distinction does not imply that secondary metals are of inferior quality.” The importance of the industries for reclaimed metal is brought out by the following table, which shows the quantity and value of secondary metals produced in 1913:

The Production of Graphite in 1913. EDSONS . BASTIN. Separate No, 14 of Vol. 2 . 7 2 pp. “In the present report there is republished in full or in abstract all of the information on graphite that has appeared in previous survey reports. This information has been amplified in some parts and brought up to date whenever possible. It will be unnecessary, therefore, for readers t o refer to any earlier survey report dealing with this mineral. ” The article covers the following subjects : Physical and chemical characteristics, origin, uses, production, and imports; and full summaries are given, by geographical sources, of the various graphite-producing districts both of this and foreign countries. The bibliography includes the more important articles of mineralogical and economic interest. It is pointed out that the production of graphite in the United States is very irregular and a t the present time only one concern is said i o be firmly established “in the treatment of such graphite rocks.” The production in the United States in 1913 was 4,775 short tons of natural graphite valued a t $293,000 and 6,817 short tons of manufactured graphite valued at $973,000. There were imported 288,791 short tons valued a t $2,109,000. The three causes for the unsatisfactory condition of the domestic industry are given as follows: “ ( I ) The superiority of much of the Ceylon graphite to any graphite that is mined in this count r y ; ( 2 ) the low cost of labor in Ceylon, which permits cheap mining, careful sorting, rubbing up, and blending of the product; and (3) the facts that the largest domestic deposits are schists which carry small flakes of graphite disseminating throughout them and the separation of graphite from the accompanying minerals, especially mica, in such rocks is a problem of unusual difficulty.” The Production of Abrasive Materials. FRAXK J. KATZ. Separate No. 15 from Vol. 2 . 2 2 pp. This report gives detailed information as to the production in this country and abroad of thc various abrasives. Details are given for the following: Millstones, grindstones, oilstones, corundum and emery, abrasive garnet, tripoli and diatomaceous earth, pumice, and artificial abrasives. The importance of these industries is shown by the following tabulation of abrasives consumed in the United States in 1913, exclusive of the various forms of silica and feldspar : Natural a b r y i v e s . . . . . . . . . . . . . . . . . . . . .

The Producti.on of Phosphate Rock in 1913. W. C. PHALEN. Separate No. 16 of Vol. 2 . 20 pp. The marketed production of phosphate rock in the United States in 1913 was 3,111,221 long tons, valued a t nearly $IZ,OOO,OOO. This was an increase of 5 per cent in quantity and I per cent in value over the previous year. Five-sixths of all the material came from Florida. The range in prices per ton was $3.20 to $6.10, averaging $3.79.
