In a recent article on “High Altitude Laboratories” inPhysics Today, November, 1950, page 17, the need for additional laboratory facilities in the equatorial zone was stressed.

Indeed four of these letters arrived one day in the same mail. Evidently such distinguished individuals as Dr. Warren Weaver are also keenly interested in this problem.
