This method of transporting fire was referenced in Ed Tom's dream at the end of No Country For Old Men:
[My father] just rode on past... and he had his blanket wrapped around him and his head down and when he rode past I seen he was carryin' fire in a horn the way people used to do and I could see the horn from the light inside of it. 'Bout the color of the moon. And in the dream I knew that he was goin' on ahead and he was fixin' to make a fire somewhere out there in all that dark and all that cold, and I knew that whenever I got there he would be there.
