Tyson's Farm is further below High Topps than Atkinson's Farm, but near enough to High Topps for the miners of SADMC to go prospecting for the lost mine in Pigeon Post. Mrs Tyson's grown-up son Robin Tyson manages the farm, with a farm-hand. They have cows to milk (PP6,16,34). Mrs Tyson is apprehensive of a fire, so the miners initially have to camp in the orchard, and sit down to breakfast and dinner at the farm prepared by Mrs Tyson. But when Titty finds water, they move up to Camp Might Have Been.
