In one instance atAssos, that of an exceptionally heavy corner piece, the entireU-shaped boss had broken away, and was replaced by a deepslot, into which the end of a beam could be inserted. Of thesecond variety, a square or oblong slot, about 8 cm. in width, isthe most simple form, and is, as a general rule, employed uponone end of all those stones which were lifted by upon both ends of which were simple slots of this kind. 0 i,„ Fig. 15.

It was necessary to cut,upon one at least of the two surfaces meeting at a joint, a ver-tical channel, through which the grapple could be released andwithdrawn. This channel was made either suffciently deepin plan for the hook of the iron — the dog — to pass freelywhen slipped backwards, towards the joint; or sufficiently
