To light any great outdoor fire one places kindling, crumple paper, wood shavings, pieces of bark on top and under large split wood or logs arrange in a pyramid shape .. when lit flames start the burn, then hot embers burn down into the center igniting the inside wood.
In 1600s, European soldiers used logs for heating, lighting and cooking. To light, place kindling such as wood shavings, pine cones needles or small pieces of tree bark on top and inside of a log. Once the tinder starts to burn, the hot embers drop down into the log, igniting the inside. Modern day lighting one would use lighter fluid, or fire starter blocks.
