The shorter upright was next set on end. A shallower excavation had to suffice in this case, but the base of the stone, as has been already intimated, was wider, and to secure greater stability blocks of Sarsen were provided for the stone to rest on, other blocks being packed in carefully as it was raised, and curiously enough among the firm packing were several large stone mauls, fitted in to make the whole mass solid and compact. There is no direct evidence as to the actual method of placing the imposts upon the uprights. It has been suggested, and with every show of reason, that one extremity of the imposts would be raised and packed with timber. The opposite end would then be similarly treated. In this way, by alternately raising and wedging first one side and then the other, the impost could have been brought, in time, level with the summit of its upright, and levered over on to the tenons. Such a method is employed by primitive races to-day. RAISING THE FOREIGN STONES The five Sarsen Trilithons already mentioned were raised into position from the inside of the circle. Investigation has shown this to be a fact. It therefore stands to reason that the Foreign Stones were erected last, and not first as has so often been supposed. This is a hard saying, for it at once negatives the picturesque legend that the Foreign Stones were a stone circle brought from Ireland, and erected by a colonial tribe, who afterwards gave dignity to their primitive temple by the erection of stately Trilithons. Furthermore, the _debris_ of the ancient mason reveals chippings of Sarsen and Foreign Stone intermingled so thoroughly as to preclude any idea of two separate periods of building. Stonehenge, therefore, was erected at one date and continuously. It is a question, as yet, if the outer Sarsen Trilithons were erected from the outside or the inside of the circle. It has not been possible, in the foregoing brief description, to enter into minute detail, but it is hoped that sufficient has been said to show the stages by which the work of building was approached.
