Mr. Irving, I marvelled at hearing that a box of tissues adds about 35 times the value of a piece of wood, or of the tree. I mean, I would have had no idea. I don't know how that compares with what the various plastics are related to the value of a barrel of oil, for example, or natural gas.
It seems to me that part of the challenge going forward is going beyond that multiple, going to higher multiples, obviously. What do you foresee as the opportunities, in terms of the innovation and R and D that you're aware of, that hold promise for the future?
