This morning, while Paul was chainsawing through the tree that fell over the driveway during the recent storm, Hil went pale for a second. Blood seemed to be gushing from a wound. Oh my god, where's the finger?... Do you need some help with that? "It's sap," said Paul, "it's from the tree." Sure enough, it was coming from a saw line, but flowing as if an artery had been severed: thick and dark red, just like human blood. Paul explained the sap was making its way back down the tree for winter. Did you know that trees could bleed? And does anyone know if you can make anything from gushing sap?
