442 The Amorpholithic Monuments of Brittany. [OGober, 
Erdeven, stretching from the road south of the village 
towards the south-east for the distance of over a mile and 
ahalf. ‘There are, as well as can be made out (for there is 
sometimes considerable difficulty in tracing these lines), ten 
lines of stones nearly parallel; the convergence is very 
slight, the breadth of the lines at the western end being 
220, and at the eastern extremity 190 feet. But it must be 
remembered that these alignments are not actually traceable 
over the whole extent of this long tract of land; about 
half way is an eminence, upon which are four dolmens and 
a long barrow, and here traces of the lines are lost for some 
distance; but the same number of lines occur again further 
east, and continue toa spot not far from the huge dolmen of 
Courconneau, and it is presumed that they formed a portion 
of the same series. There is a slight deviation between the 
direction of the eastern and western portions, but only of 
3, the western portion being 117°, and the eastern 120° to 
the east of the meridian. 
From near the head of these lines is an alignment con- 
sisting of 25 stones extending ina N.E. direction (42° E. of N.) 
for a distance of 354 feet. The stones are at present all 
prostrate, excepting erect menhirs at either end. They are 
all large stones; in fact the largest masses to be found 
throughout all the series of alignments in Brittany, the 
largest measures 21 feet 6 inches long by 10 feet broad and 
5 feet thick; two others are nearly as bulky within a few 
inches. What the meaning of this diagonal line outlying 
the main body of the Erdeven lines can be is a mere matter 
of conjecture. It is certain that the blocks lie close 
together as those composing the circles, at Menec and 
Kerlescant. If this, therefore, was portion of a circle, it is 
the sole example of one north of accompanying lines. At 
the eastern extremity of the Erdeven lines, but at some 
small distance, is an enclosure of stones nearly oblong, 
measuring 150 feet long by 85 broad. 
Whilst on this subject, it would be wrong to omit any 
mention of the Red Carnac pebbles—although they are not 
mentioned in Mr. Lukis’s paper, nor even alluded to by the 
Vannes Society—which occur in multitudes, wherever there 
are these lines of menhirs. Whether the sites of the align- 
ments have been chosen from the presence of these pebbles, 
or whether these pebbles are the concomitants or deposed on 
the sites of the alignments, or whether they form part of a 
regular geological deposit wholly distinét from any con- 
nection with the menhirs, is at present undetermined ; and 
these stones have proved a puzzle to some of the best
