Burns much better than wood in its natural form, and that logs from twelve to fourteen inches are best for splitting for fuel (Fig. 42); also one must not forget that in starting a fire the smaller the slivers of kindling wood are made, the easier it is to obtain a flame by the use of a single match (Fig. 36), after which the adding of fuel is a simple matter. A fire must have air to breathe in order to live, that is a draught, consequently kindling piled in the little wigwam shape is frequently used.
