From p 94 of "The Colossus of Golf:"
"In 1867 the Green Committee of The Royal and Ancient applied itself to the problem and DL Burn proposed that the area to the west of the last loop of the Swilken Burn, before it meets the sea, be cleared of whins to make a putting course for the ladies. Mrs Boothby and her daughter would appear to have been the main driving force when Tom engaged extra labour to clear the land and make what came to be known, and is still known, as the Himalayas Putting Green."
EDIT: Malcolm's book does not provide an endnote on this passage.
