I think it was LF
Conifer sap ... hmm is that edible like maple?
I am pretty sure it is Ferlinghetti, because it sounds like his famous poem about his dog. Unfortunately all my books are temporarily inaccessible as I rearrange my apartment so I can't find out for sure, but I'm pretty sure this is it. And I wish I knew the title. Something with the word "Dog" in it.
