Go down to the stream. Find a flat pebble with an indentation in the middle. Dry. Gather pine sap with slate knife, scrape into indentation in pebble. Climb a cattail tail frond and gnaw the cattail off. Pull a bit of the fluff of the cattail off, store the rest in one of the storage tunnels. Stick the fluff in the pine sap in the pebble. Let the fluff soak up the sap for a bit. Light. This is your lamp! Be careful not to light the sap! This is a lamp for little critters, not people!
