@Sawbones listening to Lactose Intolerance today and am reminded of something I saw:
To stop ants from coming into your house leave a saucer of milk outside. The adult ants drink it and it has an effect on ant reproduction.
@LOTR_Daily_ At the end of the prologue we are told that when Celeborn sailed into the West he took with him the last living memory of the Elder Days. This means that the ship must have been made out of Treebeard.
