Fig. 153 gives the plan of the tie-beams and piles of the marniera of Castione, taken from the author's work.[34] These slabs or joists were not fixed in any way; at least, no trace now exists of any fastening. They seemed to have been provided by splitting trunks of trees by means of wooden wedges, a number of these wedges having been found in the peaty earth. Neither the saw nor the gimlet appear to have been employed; but the square holes have been cut out by means of the chisel. The timber that was used was principally ash and oak.
