Helium and Airships

Abstract

IN a recent article on the British dirigible programme (NATURE, December 6, p. 842) it is stated “The United States naturally hold for themselves the only supplies of helium.” Of course, it must be admitted that the United States authorities, ever since 1918, have pressed with vigour the investigation of their resources of helium, its production and use. At the present time the two large dirigibles, the Shenandoah and the Los Angeles, are inflated with helium. Processes of repurifying the gas in them have been devised and applied. A more efficient and cheaper method of production than the present Linde process has been worked out by the U.S. Bureau of Mines, and much valuable scientific data have been accumulated.
