I'm reading The Lost Princess by #GeorgeMacDonald and in one paragraph he starts off by saying that there is a fire made of fir-wood and by the end of the paragraph refers to it as a peat fire.
#ChatGPT informs me that fir-wood is fast burning and was often used in #Scotland to get a fire started while peat was long-burning and thus would be added to the fire thereafter.
It seems logical, but ChatGPT has also struggled to provide me with clear references to this information.
Curious if anyone is familiar with whether this was/is so? I'd like something to depend upon beyond the words of generative AI. 😂
