At the same period the two rites appear to have been practised simultaneously in Armorica, but there incineration was the dominant custom. In one hundred and forty-five megalithic monuments supposed to date from the Neolithic period, seventy-two give proof of incineration and twenty of inhumation only. The others yielded a few cinders, but it was impossible to come to any definite conclusion. In many cases, as we have seen, the megalithic monument was surrounded by a double or triple _enceinte_ of stones without mortar. Inside these _enceintes_ were some small circular structures made of stones reddened by the action of heat. In the lower part of these structures were openings to admit a current of air to fan the flames. These strange structures, full of cinders and black greasy earth, bear the significant name of _Ruches de Crémation_.33 Of thirty-nine sepulchres of the Bronze age twenty-seven gave evidence of incineration, two of inhumation, whilst ten decided nothing one way or the other.34 The dolmen of Mont St.-Michel and that of Tumiac are separated by a short distance only; they were erected by the same race and probably about the same period, yet at Mont St.-Michel we find incineration, while inhumation was practised at Tumiac. How explain this difference in funeral customs? Does it imply a diversity of race, of caste, of religion, or of social position, or may it not rather be explained as being merely the result of those later displacements which upset the most careful reasoning? Whatever may have been the cause of the different modes of burial, we meet with them in every country. In Scandinavia, during the Bronze age, cremation and burial were practised in about equal proportions. Similar facts are noticed in Germany, but in the North incineration predominates, while in the West it is inhumation. Beneath the cairns of Caithness in Scotland, we find some bodies lying at full length, while others are in a bent position, and large jars of coarse pottery filled with cinders and calcined bones which had belonged to men of medium height. One of the largest of these jars is fifteen or sixteen inches high by forty-nine wide at its largest part.35 In excavating the barrows of the Orkney Islands, Petrie noted the practice of both modes of burial36; but were those buried in manners so different contemporaries? This is what we are not told, and what we have to find out.
