[101] “France, indeed, furnishes us with a stepping-stone, as it were, between the natural cave and the dolmen in certain artificial caves which offer comparison both with the former and the latter... the natural cave was scooped out into a large chamber or chambers either by the swirling of water pent up in the limestone or other yielding rock and finding its way out through some narrow crevice. The ground plan and section, therefore, is that of an allée couverte with a vestibule... the artificial cave is modelled on the natural one, and yet bears, as M. Mortillet points out, a close resemblance to the dolmen.”

[103] It is interesting to point out in relation to the fact that different swarms successively introduced the May and solstitial years that the “sleeping rooms” of the May year cairns at New Grange are about 3 feet square, while at the solstitial Maeshowe, built very much later, the dimensions are 6 feet × 41⁄2 feet. There were differences of sleeping posture in the old days among different peoples as well as different methods of burial.
