Various measurements made during ten controlled head fires in the New Forest have been reported by Woolliscroft, who calculated that flame radiation contributed significantly to the spread. Here, these data are discussed further. There are two or three apparently anomolous rates of spread which one cannot resolve with the few data available, but the rate of spread is broadly related to the amount of fuel and the wind speed, viz R?b = a + bu where R is the rate of spread in m/s ?b is the bulk density of the fuel in kg/m^3 (including water content) u is the wind speed m/s a is 0.15 kg/m^2s^1 b is 0.16 kg/m^3
