Experimental shock-tube data for the aerodynamic heating at the stagnation point on spherical bodies at superorbital and suborbital flight velocities (U/sub/0) have been compiled from a number of sources and compared to theoretical predictions. It was found that the empirical correlation given by Detra, Kemp and Riddell is remarkably close to a least-squares fit of the data. It is therefore recommended that their correlation be used for continuum flow theoretical predictions of the laminar hypersonic convective stagnation-point heating rate to spherical bodies in the region U/sub/0 - 6000 to 58,000 ft/sec.

A method for the comparative evaluation of geothermal prospects in the Eastern United States is proposed and illustrated. Comparisons are based on quantified data from geologic, engineering, and socio-economic sources including temperature gradient, depth to basement, drilling costs, population, and distribution by town size, as well as energy use in residential, commercial, and industrial applications.

Letter from D. W. Kempner to D. S. Correll of the United States Department of Agriculture discussing the genus of the Farleyense fern he has been searching for, which can be likened to the Maidenhair fern, in order to identify where it may be supplied.

Letter from botanist D. S. Correll to D. W. Kempner discussing the letter Kempner sent to the American Fern Society about the search for Farleyense ferns that was forwarded to him. Correll asks that Kempner specify the genus of fern or send a fragment for identification.
