The statistical test in appendix C indicates that the alternative method presented 

 here can be used for fuel near the size of excelsior to obtain the reaction velocity 

 used by Rothermel to describe the dynamics of a horizontally spreading fire. ' Investi- 

 gations at larger fuel sizes are necessary to extend the range of the usefulness of 

 this method. 



This method should be useful in studying fire spread in forest fuels comparable in 

 size to excelsior. Some specific applications that come to mind are; dependence of fire 

 spread on natural variables such as mineral content, moisture content, extractive 

 content, and packing ratio, and also the efficacy of fire-retarding chemicals.
