The prehistoric axe was probably regarded as gifted with fetish power, even in the earliest age, especially when it was made of certain rare materials. Thus among the Red Indians of Massachusetts stone "tomahawks" of veined, petrified wood were specially consecrated to burial-places, while in Europe axe-heads of jade were the most coveted of possessions. A. B. Meyer has written a large work, "Jade und Nephrit Objecte aus dem Ethnographische Museum zu Dresden, America und Europe" (Leipzig, 1882). It has always been supposed that the objects of true jade came only from Tartary, and I believe that I was the first person to discover that it existed in quantities in Western Europe. The history of this "finding" is not without interest. It has been usual--it is said for a thousand years--for pilgrims to Iona to bring away with them as souvenirs a few green pebbles of a peculiar kind, and to this day, as every tourist will remember, the children who come to the steamboat offer handsful of them for sale. When I was there many years ago--in Iona--I also went away with perhaps twenty of them. One evening, after returning to London, there were at my home three Chinese gentlemen attached to the Legation. The conversation turned on Buddhist pilgrimages and Fusang, and the question, founded on passages in the Chinese annals, as to whether certain monks had really passed from the Celestial Kingdom to Mexico in the fifth century and returned. This reminded me of Iona, and I produced my green pebbles, and told what I knew about them. My visitors regarded the stones with great interest and held an animated conversation over them in Chinese, which I did not understand. Observing this I made them presents of the pebbles, and was thanked with an earnestness which seemed to me to be out of all proportion to the value of the gifts. Thinking this over the next day, I wrote to the clergyman at Iona asking him to be so kind as to send me some of the pebbles, and offering to pay for them. He did so, sending me by mail a box of the stones. Two or three were very pretty, one especially. It is of a dark green colour and slightly transparent. Two years after, when in Philadelphia, meeting with an old friend, Dr. Joseph Leidy, well known as a man of science, and, inter alia, as a mineralogist. I showed him my pebble and asked him what it was. He replied, "It is jade." To my query whether it might not be nephrite he answered no, that it was true jade of fine quality. Jade is in China a talismanic stone, many occult virtues and luck-bringing qualities being ascribed to it. It is very curious, and possibly something more than a mere chance coincidence, that the green pebbles of Iona were also carried as charms. It would be remarkable if even in prehistoric times, or in the stone age, Iona and Tartary had been connected by superstition and tradition.
