In respect to these, what we find at Carnac seems the exact converse of what exists at Stonehenge and Stennis. There the great stone monuments stand among the pigmy barrows of another race and age. Here all are megalithic and all seem to have been erected nearly at the same time, and to belong to one people, whoever they may eventually be proved to have been. In so far as any argument as to their age is concerned, it is at present of little importance whether this is so or not, for they are all equally uncommunicative on this subject.
One of the tumuli known as Mont St.-Michel, is so situated with respect to the Maenec row that it seems impossible to dissociate the two. It was opened by M. René Galles in 1862, and an account of his researches, in the form of a report to the Préfet, was published shortly afterwards. The mound itself, at its base, is nearly 400 feet in length by half that dimension in width. In modern times its summit has been levelled, to form a platform for the church which now occupies its eastern summit. In front of the church, M. Galles sunk a shaft near
