In order to meet the ever-increasing demand by consumers for uniformity of ground talc, a new method of blending its finished product has been developed by Gouverneur Talc Company, Inc., at its plant near Gouverneur, N. Y. The method has been in use for a sufficient length of time to be now judged a success. The Gouverneur district is the leading talc producing area of the world, inasmuch as more tonnage is produced there than from any other state in the U.S. or, so far as is known, from any other locality in the world. Almost all of the output goes into industrial uses, with ceramics and paint being the principal consuming industries. The physical and chemical specifications imposed by these industries are stringent and the trend, as in most industries, is toward ever increasing severity. The blending method described herein has aided Gouverneur Talc to keep up with this trend.

JOULE-THOMSON coefficients for two natural gases were determined at pressures up to 600 lb. per sq. in. throughout the temperature interval between 70° and 310°F. From these primary data and available information relating to the isobaric heat capacities of the components at infinite volume, the heat capacities of these gases were computed throughout the above-mentioned range of pressures and temperatures. The enthalpies of the gases were computed as a function of state and the results compared with values obtained by several methods of prediction currently available. The results are presented in graphical and tabular form.

During the nineteen months in which our country was actively engaged in the war, the United States Shipping Board Emergency Fleet Corpn. expanded the shipbuilding capacity of the United States from an unimportant position among the world's producers of ocean-going tonnage to first place. At the same time it increased the overseas merchant fleet of the United States from a negligible quantity to second place. The shipbuilding program has been greatly reduced since the signing of the armistice. There have been suspended or canceled contracts for 754 ships aggregating 3,797,825 deadweight tons, which would have cost $797,564,276 to complete. The cost of canceling these contracts will be about $202,853,456, and the saving effected by cancelations will approximate $594,710,820.

Officials of the State Department have expressed their hope that a considerable number of technical men will take the examination for consular service. The Department recognizes that the interest of the United States will be served best if technical men are made available through these examinations for vacancies at points where their training will be of special value. Industrial engineers who have passed the con-sular examination will be assigned to industrial centers of Europe or South America. Mining engineers, chemists, electrical engineers, etc., will be assigned to industrial centers requiring special training.

Every 12 minutes, a cable operated skip car appears from beneath the desert surface of Arizona's Papago Indian Reservation. The Papagos have become quite used to the car, particularly those whose paychecks depend upon its regular appearance. The 24-ton capacity skip or tramcar hauls copper ore out of the North Decline of Hecla Mining Company's new mine about 30 mi south of Casa Grande. While there's nothing particularly glamorous about the skip itself, the railroad system upon which it travels is interesting because of the unconventional way it was built.
