Impatience from the Rev. Edward Daniel Clarke, who probably believed all sorts of unlikely things himself.
The superstition of the inhabitants, not only of Mull, but of the neighbouring islands, is beyond belief. Stones of any singular form.. have each a peculiar characteristic virtue. They are handed with veneration from father to son, and esteemed as a remedy for every species of disease incident to the human or animal race. As there is not in the whole island of Mull a single surgeon or apothecary, it is well for the natives they can have recourse to a mode of relief so universal and so efficacious.
.. It was with much difficulty I could prevail upon these credulous quacks to part with any specimen of their potent charms. I succeeded, however, in purchasing two, during the time I remained in Mull. One of these, a hard and polished stone, evidently appears to have been once used as an axe, or hatchet, and bears a strong resemblance to the specimens of similar instruments brought by circumnavigators from the South Sea islands. The other is of the same nature with the first, with respect to the use for which it was originally fabricated, although it differs in its composition; it was probably once an instrument of war.
By holding the former over the head of any diseased cattle, and pouring water upon it, letting the water at the same time fall on the animal, the beast is said to recover without fail. The latter is a sovereign remedy against barrenness in cows, if it be used in the same way. If either of them be dipped in water, the water cures all pains of the head or teeth, it also removes the rheumatism or sprains in the joints, with a variety of other virtues, too numerous to mention.
Several others which I saw, possessed virtues as various as their forms. Some of these were fossil shells; others like the flint of a gun, called Fairy speds*; and again, others, mere oblong pebbles, which they distinguished by the appellation of 'Cockaroo-hoo-pan', a sovereign antidote for barrenness in the female sex.
* I guess these could have been flint arrowheads. 'Sped' means 'discharged or let go' which sounds like what a fairy might do to an arrow? Also, if anyone's got an axe I'd like to try it on my sciatica please.

A green mound, near the village of Pennygown (Peigh'nn-a-ghobhann), in the Parish of Salen, Mull, was at one time occupied by a benevolent company of Fairies. People had only to leave at night on the hillock the materials for any work they wanted done, as wool to be spun, thread for weaving, etc., telling what was wanted, and before morning the work was finished. One night a wag left the wood of a fishing-net buoy, a short thick piece of wood, with a request to have it made into a ship's mast. The Fairies were heard toiling all night, and singing, "Short life and ill-luck attend the man who asked us to make a long ship's big mast from the wood of a fishing-net buoy." In the morning the work was not done, and these Fairies never after did anything for any one.

If you access this site from the castle cafe and shop then the walk is pretty gentle and it's very easy to find. You walk past the front of the castle (at a distance) which is a handsome building and decend to the stones, all through open ground with some wonderful sea views.
Parking at the cafe /shops is very limited, and the excellent cafe (WELL worth a visit!) is popular with vistors and locals alike, so if you intend to do this try not to go over the main lunch period.
When we visited at Easter 2010 there was a large bull being kept in the Druids field so we obviously didn't dare enter - but there also wasn't any warning he was there so we could have got caught out!
Also a note on actually finding Druid Field / the circle - once you are parked up in the signposted spot next to the road, head across the field in front of you following the white painted boulders, but when they lead you to the field fence you follow it along on the *same side* which will lead you through a gate and along the side of the Druids Field to another gate leading into that area. We could see what appeared to us to be more painted boulders in the next field and ended up crossing field boundaries and getting very lost!
Also at that time of year the field was *extremely* wet and thick with very sticky, deep mud - enough to go over the tops of childrens wellies and take off even a heavy adults boot with suction. We ended up having to criss cross the field finding the driest path to make it passable at all (also beware the slippery boards over ditches) - so go prepared folks!
