4. The stone row is almost invariably associated with cairns and kistvaens, and clearly had some relation to funeral rites. The stone settings are often single, sometimes double, or are as many as eight. They do not always run parallel; they start from a cairn, and end with a blocking-stone set across the line. In Scotland they are confined to Caithness. The finest known are at Carnac, in Brittany. It is probable that just as a Bedouin now erects a stone near a fakir's tomb as a token of respect, so each of these rude blocks was set up by a member of a tribe, or by a household, in honour of the chief buried in the cairn at the head of the row.
It is remarkable how greatly the set stones vary in size. Some are quite insignificant, and could be planted by a boy, while others require the united efforts of three, four, or even many men, with modern appliances of three legs and block, to lift and place them in position. This seems to show that the rows are not the result of concerted design, but of individual execution as the ability of the man or family permitted to set up a stone large or small. Usually the largest stones are planted near the cairn, and they dwindle to the blocking-stone, which is of respectable size.
There is no district known so rich in stone rows as Dartmoor. As many as fifty have been observed. The finest are those of Drizzlecombe, where there are three double rows, not parallel; Down Tor, a single line; Merrivale Bridge, two parallel double rows, but the stones constituting them small; Stall Moor, a single line that looks like a procession of cricketers
