"Simply get an old red brick, hammer it to dust, and spread the dust around the front of your house, using a broom. Keep a pan of water that has been treated with a ball of Indigo bluing (anil) behind your front door, and draw crosses using cascarilla behind every door of the house. Add a couple of drops of urine from a child and use the mixture as a floor wash, this will complete making your home hex-proof."
