Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Salisbury National Topographic Map segment (NJ 18-5 quadrangle) including a description of the program and results with the flight line profile data and statistical analysis results.

From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."
