On the Stone Avenues of Carnac. 



One exists in the Ile-aux-Moines, and a second on Isle-Lanic. The 

 third, at St. Pierre, Quiberon, is not far from a group of avenues. 

 Not one is in a perfect condition. 



The first is a crescent or horse shoe form, and it has been questi- 

 oned whether it was ever more than a segment of a circle. The 

 distance between the two points of the crescent is 322 feet. 



The second is upon a very small island close to Gavr' Inis, the 

 island being only about 200 yards in diameter. On the south side 

 the land slopes gently towards the sea, and on this slope lie the 

 remains of a circle of 165 feet in diameter. Three only of the 

 stones are standing, the others are fallen. The sea has encroached 

 upon the island, and its stormy waves have carried away a portion 

 of the circle, and continue to destroy both it and the island annually. 

 "When Sir Henry Dryden and I planned it in 1868, the tide hap- 

 pened to be low, and we had a good opportunity of observing some 

 of the stones that had completed the circle lying on the beach and 

 rocks, and resting not far from their original places. This is the 

 only example with which I am acquainted in Britanny where the 

 pre-historic people have left abundant traces of the unknown customs 

 which they practised upon such spots, and I trust it will receive, as 

 it deserves, a most careful examination with the spade from the 

 proprietor. Not only is the area of the circle thickly strewn with 

 fragments of clay vessels, coarse and fine, ornamented and plain, and 

 with animal bones and stone implements of various kinds, such as 

 chisels, scrapers, knives, and hammers, but the whole of the small 

 island itself appears to be sown with these objects. While we were 

 engaged in planning, I picked up several good specimens of them 

 that were lying on the surface, or had been brought to light by the 

 action of the waves. 



The third is 195 feet in diameter, and has been deformed by the 

 cultivators of the land, many of its stones having been displaced. 

 I was informed, in 1869, that the proprietor or occupier intended 

 removing what remains of this circle, because the stones interfere 

 with his agricultural operations. 



I know of one example only of a square of menhirs in Britanny, 

 and this is in the Morbihan, on the borders of the parish of Erdeven,
