 soon found by use which kind lighted quickest 

 and which burned longest and with the most 

 steady heat, facts which the subtle analysis of 

 the chemists only confirmed. The conifers light 

 most readily and burn rapidly with the greatest 

 heat in a given time. The hard woods burn long- 

 est, some of them retaining fire for a surpris- 

 ing length of time under just the right conditions. 

 The woodsmen will tell you that the pines light
