Mathematical problems encountered in the measurement of heat flow at the Earth's surface are reviewed. Most of these problems can be solved by simple solutions of the equation of heat conduction. Reduction of observations in drill holes for horizontal layering are given by the methods of Bullard and Gough. Described briefly are: heat production; the methods of Jeffreys and Bullard, Lees, and Birch for topographic correction; perturbations of the temperature gradient caused by the oscillations of surface temperature; past climatic changes; uplift and erosion; igneous intrusion; groundwater circulation; mine ventilation; the process of drilling and circulation of drilling fluid; and the sudden insertion of temperature probes. The theory of transient methods for determining thermal conductivity and the effect of anisotropic thermal conductivity are also discussed.
