Refrigerants from the Tropics Y O U N G as we are, we can remember the days when sailing vessels carried cargoes of natural ice from Maine to Cuba, and we believe even as far as Calcutta. How times have changed! There is now en route to New York from Mexico one of three vessels, each of which has been equipped with a compartment insulated against heat exchange by 12 inches of cork board to bring solid carbon dioxide to the metropolis for refrigerating purposes. One of the petroleum companies in drilling for oil struck a supply of carbon dioxide, which rushed to the surface a t a pressure of 1000 pounds per square inch, and the present project has for its purpose the exploitation of this natural resource. It is much too early to discuss the economics of this venture. Inasmuch as the gas must be cleaned of its impurities before it can be made into solid carbon dioxide, it is doubtful whether the natural high pressure will be of much advantage, and undoubtedly there have been some nice technical difficulties in the purification of this particular supply of gas. We have yet to learn, too, with what efficiency and what percentage of loss the solid gas has been stowed in the hold, transported, unloaded, and distributed. These are technical details concerning which no information has so far been made available. However, the whole venture is intriguing, The mere thought of preparing a refrigerant in the tropics for shipment into the Temperate Zone is so complete a reversal of the old established practice as to afford another example of how chemistry is helping to remake the world.

and will be afforded much help in locating his particular niche in a great organization. Officials, through weekly addresses, place emphasis on phases of the company’s affairs which might otherwise be overlooked. This training plan is really one of selective apprenticeship which, through a series of years, should find men fully capable of discharging exacting duties in the lesser as well as in the more important positions of the organization. Not so many years ago young men and women trained themselves and hoped to find a place in which they would fit. A few pointed for work which they knew they wanted, and some were able later to engage in it. Today the exceptional man is sought by the industry, is given an opportunity for specialized training, and is materially assisted in making himself valuable to his employer. It is a good thing for industry, and even better for the well-trained individual.

International Critical Tables E ARE about to see concluded a monumental work which has engaged the active attention of a group of

chemists and physicists and the collaboration of numerous colleagues for almost a decade. When Volume VI1 of International Critical Tables makes its appearance during the year, the curtain will be rung down on what we hope is but the iirst of a series of compilations planned to make immediately available certain products of scientific research to their ultimate consumers. International Critical Tables were undertaken as a National Research Council project to provide an improved LandoltBornstein more readily available to those who have but limited working knowledge of technical German. Originally the plan also called for an edition in English of a work similar NDUSTRIES largely founded on the work of science not to Beilstein, this to be undertaken by our British colleagues, only have made greater progress than those time- but it was later abandoned.
