Pink Note (phenomenon)

On September 29, 1880, Mrs. Patience Sinnett, Mme. Blavatsky and Col. Olcott went for a picnic to the top of Prospect Hill at Simla. There, Mrs. Sinnett received a note on pink paper from one of the Masters. It was left in a tree and read: "I believe I was asked to leave a note here. What can I do for you?" The original of this "pink slip" is in the British Library.
