Savage has suggested that an energy flux of 2 • 101~ erg cm -2 s -1 passes through the umbra of a sunspot in the form of hydromagnetic waves. In this paper some of the consequences of this flux are considered. It is first shown that it is not inconsistent with the energy requirements for the heating
