149. If you ever really NEED to know how to do this, you're in serious trouble! |

Beat some the dry wood into as fine a pulp as you can with the rock, until you have a small pile of very fine fibers & shavings to start your fire with.
Find the CLEAREST section of ice you can- you'll need a piece 5 or 6 inches thick, big enough to carve into a 18-24 inch circle.
Then, by rubbing with the rock, grind that piece of ice into a bigass MAGNIFYING LENS. When the shape is right, friction-polish it by rubbing briskly with your gloved hand. (assuming your gloves aren't back at the house with your matches)
Obviously, ice doesn't make as good a lens as glass does- that's why you need such a big one. But an ice lens that size CAN focus enough sunlight to ignite that bed of dry wood pulp you prepared.
