Certain wells could put in a good claim to the title of wonderful on the ground of the effects they were able to produce. If a spring could act as a sign-post to guide the wayfarer, who had strayed from his path, it might surely be classed among marvels! This is what a certain well on Dartmoor, in Devonshire, could do, at least in the sixteenth century. A man of the name of Fitz and his wife, when crossing the moor in the year 1568, lost their way. They lighted on the well in question, drank its water, and found the lost track without the least difficulty. In gratitude, Fitz afterwards raised a memorial of stone over the well "for the benefit of all pixy-led travellers." In Germany, before a meal, the ceremony of wishing one's friend a good appetite is still kept up. Such a salutation must have been unnecessary in the Island of Harris, at least in Martin's time, for he tells us of a spring, then lately discovered, that could produce an appetite whenever wanted. "The natives," he says, "find by experience that it is very effectual for restoring lost appetite; all that drink of it become very soon hungry though they have eat plentifully but an hour before." A small quantity of its water might with advantage be added to the contents of the "loving cup" at the Lord Mayor's banquets, and on other festive occasions both in, and out of the Metropolis. Martin speaks of another marvel in Harris. "A large cave in the face of a hill hath," he says, "two wells in it, one of which is excluded from dogs, for they say that if a dog do but taste of the water, the well presently dryeth up; and for this reason, all such as have occasion to lodge there take care to tie their dogs that they may not have access to the water. The other well is called the Dogs' Well, and is only drunk by them." The student of folklore cannot fail to find Martin a congenial companion, as he records a variety of quaint Hebridean customs that might have been passed over in silence by a more matter-of-fact writer. When in the Island of Lewis, he was told of a fountain at Loch Carloway "that never whitened linen," though the experiment had been often tried. In connection with his visit to Barray, he says, "The natives told me there is a well in the village Tangstill, the water of which, being boiled, grows thick like puddle. There is another well, not far from Tangstill, which, the inhabitants say, in a fertile year, throws up many grains of barley in July and August. And they say that the well of Kilbar throws up embryos of cockles, but I could not discern any in the rivulet, the air being at that time foggy." This reminds one of the Well in the Wall in Checkly parish, Staffordshire, said to throw out small bones like those of chickens and sparrows all the year round except in the months of July and August. Toubir-ni-Lechkin, in Jura, rising on a hill near Tarbert, was a noted fountain. Martin mentions that its water was counted "lighter by one half" than any
